What is SunVox

SunVox is a small, fast and powerful modular synthesizer with pattern based sequencer (tracker). It is a tool for those people who like to compose music wherever they are, whenever they wish. On any device. On any system.

Official SunVox page: http://www.warmplace.ru/soft/sunvox

List of terms

  • BPM - number of Beats Per Minute.
  • Envelope - graph of the dependence of some parameter (volume, for example) on time.
  • LFO - Low Frequency Oscillator which is used to modulate some synth/effect parameters (frequency, volume, panning, etc.);
  • Panning - the sound location in the left-right stereo space.
  • Phase - position of a point in time on a waveform cycle (in Generator) or on a sample. Usually this means the initial phase, not the current position.
  • Sample:
    • amplitude of the audio signal at a point in time;
    • portion of some sound in digital form: set of the values (amplitudes) described above; it can be very long (loop or the whole audio track) and very short (one note of some instrument).
  • Sample rate - number of samples per second.
  • Sustain - suspension point (until the Note OFF) on the envelope.
  • Tick - smallest time interval in SunVox pattern.
  • TPL - number of Ticks Per Line.
  • Velocity - universal parameter combining such types of expression as the velocity (how fast or hard the keys are pressed) and the aftertouch (amount of force on held-down key). It can be changed at any time in the life cycle of a single note.

Comparison of different versions

System Supported architectures Sound engine format Multi-touch MIDI GPIO
Linux x86, x86_64, ARM (Maemo-based devices, Raspberry Pi, PocketCHIP, etc.), ARM64 (PINE64 etc.) 32-bit floating-point / 4,12 fixed-point YES Full support YES
Windows x86 32-bit floating-point / 4,12 fixed-point YES Full support
Windows CE ARM 4,12 fixed-point Export and Import only
macOS x86, x86_64 32-bit floating-point Full support
Android ARM, x86 32-bit floating-point / 4,12 fixed-point (on devices without FPU) YES Export and Import only YES
iOS ARM 32-bit floating-point (iOS 7 and higher) / 4,12 fixed-point YES Full support

As you can see, there are two sound engine formats in SunVox. Let's look at them in detail.

  • 32-bit floating-point - using high quality 32-bit (and 64-bit in some cases) floating-point computations for the sound synthesis. Math coprocessor (FPU) is required. Can be used on most of modern computers.
  • 4,12 fixed-point - using low quality fixed-point (4 integer bits and 12 fractional bits) computations. Specially for the slow computers without FPU. Such version of the engine will be much faster than the 32-bit one, but a small amount of the quantization noise will be present in sound. In this case the 32-bit WAV export may be with better sound quality due to the absence of the signal clipping.

In some cases the sound engine format will be selected automatically. But in some cases (in Linux, for example) you can choose it manually: there are several versions of SunVox with different engines.
You can always find the information about the current engine format in the SunVox Main Menu → About window.

Interface description

The SunVox interface is divided into the several rectangular areas (windows):

  • pattern editor;
  • musical keyboard;
  • controllers of the selected module + modules (routing);
  • timeline (select the pattern here and its content will be shown in the pattern editor at the top).

Each area has its own menu with different options and functions - use the button with three horizontal lines to open this menu. Click on some area sets the focus on this area.

First click on the Stop button - stop playing. Second click - reset all SunVox activity and switch the engine to standby mode.

Basic concepts

Project

The SunVox project consists of the following parts:

  • modules generates the sound;
  • patterns controls the modules (sends them notes and other commands);
  • timeline determines the order of the patterns.

All the project parts are stored in the single *.sunvox file. The sound of the project should be the same (or close to the original) regardless of the device and system.

A few words about hex numbers. Memory locations and software in today's computers use the hexadecimal (hex) number system which comprises sixteen distinct symbols, digits 0 - 9 and letters A, B, C, D, E, F (or a - f) where the letters represent the numbers 10 - 15. For more detail on the hexadecimal system please visit: http://en.wikipedia.org/wiki/Hexadecimal

Examples of hexadecimal numbers and its decimal (dec) equivalents:

  • 00 = 0;
  • 01 = 1;
  • 09 = 9;
  • 0A = 10;
  • 0B = 11;
  • 0C = 12;
  • 0D = 13;
  • 0E = 14;
  • 0F = 15;
  • 10 = 16;
  • 11 = 17;
  • FF = 255

Pattern

Pattern is a group of simultaneously played tracks that represents some section of the SunVox project (score). It is divided into horizontal lines. Playing direction is top-down.

Any pattern in the SunVox looks like this:

line track 0 track 1 track 2
000 event event event
001 event event event
xxx

event - some music event (something like a MIDI command).

Examples of events:

event of turning note C5 on: C5 80 01 0000 0000
event of turning note A5 on: A5 80 01 0000 0000
event of turning note off: ==

As you can see, an events contain several text/numeric columns (fields). All numbers in the pattern are represented in HEXADECIMAL format.

Event format: NN VV MM CCEE XXYY

Lets see detailed description of each column in the event:

  • NN - some special command code or the note:
    • SP - Set Pitch XXYY, where 0000 - highest possible pitch, 7800 - lowest pitch (note C0); one semitone = 100 (256dec)
    • << - Previous Track; use it to apply effects to previous track; but the following secondary effects are not allowed: 2x, 40..5F, 1D;
    • == - Note OFF;
    • C0 - С-0 (first note of the lowest octave);
    • c0 - C#0;
    • D0 - D-0;
    • d0 - D#0;
    • E0 - E-0;
    • F0 - F-0;
    • f0 - F#0;
    • G0 - G-0;
    • g0 - G#0;
    • A0 - A-0;
    • a0 - A#0;
    • B0 - B-0;
    • C1 - C-1 (first note of the octave 1);
    • B9 - B-9 (last note of the highest octave);
  • VV - velocity (00..80);
  • MM - module number (00,01,02,03,04,05,06,07,08,09, … FF);
  • CC - the controller number (01,02,03, … 7F) or the MIDI controller number (80,81,82, … FF);
  • EE - effect that will be applied to the last note activated on the current track; some effects (marked in bold) can use the last nonzero parameter when XXYY = 0:
    • 01 - slide up (portamento up; sliding speed = XXYY);
    • 02 - slide down (portamento down; sliding speed = XXYY);
    • 03 - slide to note (sliding speed = XXYY);
    • 04 - vibrato; (XX - frequency; YY - amplitude);
    • 07 - set phase (or sample offset) XXYY in percents (from 0000 (0%) to 8000 (100%));
    • 08 - arpeggio (XX - second note increment; YY - third note increment);
    • 09 - set phase (or sample offset) XXYY in samples*256dec;
    • 0A - slide velocity up/down (XX - up speed; YY - down speed);
    • 0F - set playing speed (XXYY: 0001..001F - number of ticks per line; 0020..00FF - BPM) or time grids (XXYY: F001..F020 and F100..F120);
    • 11 - fineslide up;
    • 12 - fineslide down;
    • 13 - set Bypass/Solo/Mute (BSM = XYY) flags; example of mute: 13 0001; example of solo: 13 0010;
    • 14 - reset Bypass/Solo/Mute (BSM = XYY) flags; example of bypass reset: 14 0100;
    • 19 - re-trigger note after XXYY ticks during the line;
    • 1C - cut note after XXYY ticks in the current line;
    • 1D - delays the start of note until tick XXYY in the current line;
    • 1F - set BPM;
    • 20 - note probability;
    • 21 - note probability with random velocity;
    • 22 - set controller value to the random number from 0000 to XXYY;
    • 23 - set controller value to the random number with range from XX (00..FF) to YY (00..FF);
    • 30 - stop playing the song;
    • 40…5F - delay an event for selected fraction of the line (from 40 (0%) to 5F (96.875%));
  • XXYY - parameter of a selected effect/controller (0000 - min; 8000 - max).

Velocity can be changed dynamically. Example:

NN VV MM CCEE XXYY
C3 10 03 0000 0000
-- 20 -- 0000 0000
-- 30 -- 0000 0000
-- 40 -- 0000 0000
-- 50 -- 0000 0000
-- 60 -- 0000 0000

In this example velocity changed from 10 to 60.

Example of changing cutoff frequency (global controller) of filter from min to max value:

NN VV MM CCEE XXYY
-- -- 01 0200 0000
-- -- 01 0200 1000
-- -- 01 0200 2000
-- -- 01 0200 3000
-- -- 01 0200 4000
-- -- 01 0200 5000
-- -- 01 0200 6000
-- -- 01 0200 7000
-- -- 01 0200 8000

The “Cutoff frequency” controller has a number 2 in the filter.

Some modules have the local controllers. A local controller can be changed for a particular note (sound) on a particular track, independently of the other sounds of the same module.

Example: (changing local controller 2 in the module 1)

NN VV MM CCEE XXYY
C3 80 01 0200 0000  //Set local controller 2 to value 0000. Separate sound begins playing here
-- -- -- 0200 0001  //Set local controller 2 to value 0001
-- -- -- 0200 0002  //Set local controller 2 to value 0002
-- -- -- 0200 0003  //Set local controller 2 to value 0003
-- -- -- 0200 0002  //...
-- -- -- 0200 0001

Pattern effects

01 - Slide up (Portamento Up). This effect will slide up the frequency of the synth being played on the track by XXYY (one semitone = 40) tones for every tick. If a slide rate is not specified (XXYY is zero) then the last slide rate used on the track is used again.

02 - Slide down (Portamento Down). This effect will slide down the frequency of the synth being played on the track by XXYY (one semitone = 40) tones for every tick. If a slide rate is not specified (XXYY is zero) then the last slide rate used on the track is used again.

03 - Slide to note. This effect will slide a note being played on a track to a specified note. The parameter XXYY (one semitone = 40) will states the speed at which a slide will occur. If a slide rate is not specified (XXYY is zero) then the last slide rate used on the track is used again.

04 - Vibrato with parameters XXYY, where the XX - frequency (examples of values: 20 - one period per line; 40 - two periods per line), YY - amplitude (one semitone = 40).

08 - Arpeggio. This effect is normally used to simulate chords. It can also be used to produce a heavy vibrato. Example: Note = C3; XXYY = 0407 (second note increment = 4; third note increment = 7) this is an attempt to produce a C-major chord. At the beginning of a line the C3 note is played, then 1/3 into the line the sound is retriggered at E-3, at 2/3 is retriggered at G3, and at the beginning of the next line (if there are no new notes to be played on the track), it is retriggered at C3 again. Video: Arpeggio Standard Effect

09 - Set sample offset. This functionality enables you to start a sample from a specified position rather than the normal beginning position. Multiply value XXYY * 256 to get the position in samples from the beginning of the sample where playback should start. If no sample is specified, the sample currently playing is retriggered to the offset specified. Example: play instrument 2 at note C3, and XXYY = 0023. This would make playback of the sample start at offset 0023 * 0100 = 2300. This offset provides quite a wide range from where you can start playing the sample.

07 - Set sample offset (by percentage). XXYY from 0000 (sample start) to 8000 (sample end). Video: Sampler Retriggering / Scaling

0A - Slide velocity up/down. This effect will change the velocity of the synth being played on a track. The value XXYY the speed of the velocity change. If XX is nonzero the velocity is increased, and if YY is nonzero the velocity is decreased. Example: set XXYY to 0003. This means that at the beginning of the line, the current velocity of the synth is decreased by 3 (because YY = 3). The velocity is decreased by 3 again for every tick on this line.

0F - Set playing speed. This effect changes the TPL (number of ticks per line). Valid values are 1 - 1F (1 - 31 in decimal). Values above 1F represent a modified BPM (beats per minute). A speed value of 2A (42 in decimal), equals 42 beats per minute.

11 - Fineslide up. This effect functions just like effect 1, except that the frequency of the note is only modified once (at the beginning of a line).

12 - Fineslide down. This effect functions just like effect 2, except that the frequency of the note is only modified once (at the beginning of a line).

13 - Set Bypass/Solo/Mute flags. BSM = XYY; Example of mute: 13 0001; example of solo: 13 0010.

14 - Reset Bypass/Solo/Mute flags. BSM = XYY. Example of bypass reset: 14 0100.

19 - Re-trigger. Effect 19 allows you to re-trigger a note after XXYY ticks during the line. For example, let's specify note C3 and set XXYY = 2 when the speed (TPL) is currently 6. This starts the specified note at the beginning of the line, and after two ticks it is restarted. This continues until the beginning of the next line.

1C - Cut. This effect turns off the note after XXYY ticks in the current line.

1D - Delay. This effect delays the start of a note until tick XXYY in the current line. For example, if note C2 is played, with effect 1D and argument XXYY = 3 when the speed is 6. The note C2 will be triggered at the 3rd tick after the start of the line. Purpose: to delay the start of a sample for a VERY short amount of time.

1F - Set BPM to XXYY;

20 - Note probability. Set the probability XXYY (from 0 to 8000) of a note being triggered. This effect can be used for original unpredictable rhythms.

21 - Note probability with random velocity. Same as effect 20 but with random velocity.

22 - Set controller value to the random number with range from 0 to XXYY.

23 - Set controller value to the random number with range from XX (00..FF) to YY (00..FF).

30 - Stop playing the song.

40…5F - delay an event for selected fraction of the line (from 40 (0%) to 5F (100%)).

MIDI Out

You can use controllers with number 80+X to send MIDI Control Change command. Where the X is MIDI Controller Number.

Example:

NN VV MM CCEE XXYY
-- -- 01 8100 0000 - set Modulation (MSB and LSB) to the min value
-- -- 01 8100 8000 - set Modulation (MSB and LSB) to the max value
MSB - Most Significant Byte;
LSB - Least Significant Byte.

Interpolator

Interpolator is a tool that provides the ability to make a smooth transition between the values of the selected area of the pattern, with various parameters (like the curve type, noise, etc.).

Description of the buttons

  • First row: type of the interpolation curve, ping-pong mode switch, interpolation step.
  • Second row: column selection (use SHIFT key to select multiple columns).
  • Third row: amount of the noise (random values) and the number of repeats.
  • Fourth row: envelope begin/end values (are only relevant for the Apply envelope button).
  • Fifth row:
    • Interpolate: New value = Smooth transition between the first and the last line of the selection. Video: Interpolation
    • Apply envelope: New value = Old value * Smooth transition between the Env.Start and the Env.end parameters. Video: How to Apply the Envelope

If you want the smooth transition between the first and the last line of your selection - use Interpolate. But if you want to change the existing values (fade them out for example) - use Apply envelope.

Module

Module is a basic element of the SunVox. There are several types of modules:

  • synthesizer (generator) - can produce some sound;
  • effect (filter) - can change the incoming sound;
  • some other modules that can generate/change not only the sound but the music events (notes, parameters, etc.) too.

Lines between the modules define the direction of signal transmission: more intensive part of line must go from the source; less visible part must go to the destination (reciever).

There is internal set of basic SunVox modules. Click twice on the empty area between the modules - and you will see the list of internal modules. You also can load some modules from the external storage medium by clicking the LOAD button under the list of internal modules. You can find several folders with additional modules (effects, instruments) in the SunVox directory.

There are three ways to connect one module to another:

  • Select the first module (source). Click on the button. Select the second module (destination).
  • Select the first module (source). Drag it to destination with SHIFT key pressed.
  • For multitouch devices: first touch on source, second touch on destination. See this simple video-tutorial.

Reconnection removes the previous connection.

Controllers

Every module has a set of parameters (controllers):

Value of any controller can be changed manually or from the pattern (automation). If you want to write the value of selected controller to the pattern - click the controller with the SHIFT button pressed. If you need real time recording - press the REC button (on the same panel with PLAY and STOP).
Click twice (or right click) on the controller to open the Controller Properties window, where you can do the following operations: change, reset, randomize, write to pattern, assign MIDI IN:

Modes

Some modules have a “Mode” parameter with the following possible values:

  • HQ - High Quality (stereo). Linear interpolation
  • HQmono - High Quality (mono). Linear interpolation
  • LQ - Low Quality (stereo) for devices with slow CPU
  • LQmono - Low Quality (mono) for devices with slow CPU
  • HQspline - High Quality (stereo). Spline interpolation

If the CPU of your device is too slow for some SunVox project (app stutters and hangs), you can use the following tips:

  • use monophonic modes (Mono, HQmono or LQmono) for the modules;
  • use low quality modes (LQ or LQmono) for the modules;
  • use reduced polyphony for generators;
  • don't use the Reverb, or use it in LQ mode and with All-pass filter disabled;
  • use the Filter instead of the Filter Pro;
  • use the Sampler without interpolation (Sample interpolation = OFF; Volume interpolation = OFF);
  • if possible, use the Generator without Attack and Release (Attack = 0; Release = 0; Sustain = ON);
  • don't use Sample rate greater than 150 in the Glide and the Sound2Ctl modules.

Timeline

Timeline defines the layout of the SunVox project. It describes how to play the patterns. Patterns can be repeated across multiple orders to save tracking time and file space.

When you select a pattern, you will see its contents (tracks, lines, events) in the Pattern Editor. In the single pattern play mode, when you select another pattern, it will play after the end of the previous selected pattern.

Playback speed is defined by the following parameters:

  • TPL (Speed) - Ticks Per Line. Tick is the smallest time interval in SunVox.
  • BPM - Beats Per Minute. Beat = 24 ticks. Number of lines per beat = 24 / TPL. So if TPL=6, Beat size is 4 lines. Or if TPL=3, Beat size is 8 lines.

Internal modules

Synths

Analog Generator

Generator with 32 double alias-free oscillators with internal 12/24dB filters, exponential envelopes and smooth parameters changing.
The sound quality of this module is better at a sample rate of 44100Hz.

Feedback

Generally the feedback is not allowed in SunVox you can't create an endless loop between the modules. But you can do it by placing two Feedback modules inside of the loop (see screenshot).

Internal Feedback delay = 20 ms.

Glide

Glide is similar to the MultiSynth (which sends the input events to the connected output modules), but it also adds the commands of smooth transition between the notes.

GPIO

With this module you can use the General-Purpose Input/Output (GPIO) pins of the device board. For example, you can send some signals to the LEDs, or receive the ON/OFF messages from the buttons.

Requirements: Linux with GPIO Sysfs Interface enabled.

Video: Using Raspberry Pi GPIO in SunVox

MetaModule

MetaModule is a full-featured copy of SunVox in a single module. So you can include one SunVox-project into another recursively. Some complex synth or effect (with large amount of the modules) may be hidden in the MetaModule. You also can use it as arpeggiator.

There are two ways to play some generator in the MetaModule:

  1. set Input Module controller to play some selected module inside of the MetaModule; polyphony is possible in the this way, because it can be handled by the selected module directly;
  2. set Play Patterns controller and play the whole SunVox project (with patterns) inside of the MetaModule; polyphony is not possible in this way, because we need a separate copy of the MetaModule for each polyphony channel, but this limitation may be removed in future SunVox updates.

MultiCtl

With this module you can control multiple controllers at once.

Controllers:

  • Value - input value;
  • Gain (normal = 256);
  • Quantization - max number of output levels;
  • OUT offset.

Video: MultiCtl Module

MultiSynth

Sends the incoming events (notes, pitch change, phase change) to any number of connected modules (receivers). So with the MultiSynth you can play a large number of synths simultaneously by pressing one note only.

Controllers:

  • Transpose;
  • Random - random frequency change;
  • Velocity;
  • Finetune;
  • Random phase;
  • Random velocity;
  • Phase - the initial position of the sample or the initial phase of some Generator.

Videos:

Pitch2Ctl

This module converts the incoming notes to the controller values (in some another connected module).

Controllers:

  • Mode:
    • frequency - use frequency (in Hz) of the incoming notes;
    • pitch - use linear pitch (first note … first note + number of semitones) of the incoming notes;
  • Note OFF action - action which will be performed after the note release:
    • do nothing;
    • pitch down (to the OUT min);
    • pitch up (to the OUT max);
  • First note (only for the mode pitch); corresponds to the OUT min value of the controller;
  • Number of semitones (only for the mode pitch) between the OUT min and OUT max;
  • OUT min;
  • OUT max;
  • OUT controller.

Sound2Ctl

This module converts the audio signal to the numeric value of any selected controller.

Input port of the Sound2Ctl is for receiving the audio signal. Output port of the Sound2Ctl is for transmitting the commands like “set controller X to the value Y”.

If you want to disable this module: just mute it, or set OUT Controller to 0.

Video: Sound2Ctl Module

Velocity2Ctl

This module converts the velocity parameter of the incoming notes to the controller values (in some another connected module).

Preferences

Go to the main menu → Preferences, and you will see the window with the main SunVox settings (not for the separate project, but for the whole SunVox app).

  • Main
  • Modules
  • Timeline
  • Interface
  • Audio
  • Recording
    • Metronome ON/OFF.
    • Fit pattern to grid: when enabled - the start position of the new recorded pattern will be multiple of 32.
    • Note quantization: when enabled - the Delay effects (40…5F) will not be used for the new recorded notes.
    • Automation quantization: when enabled - the Delay effects (40…5F) will not be used for the automation (controller changing) commands, and the pattern size will be much more compact (one track per controller) and readable.
  • MIDI

Configuration file

In most cases, you should not change this file manually, because the main settings are available in the SunVox Preferences window. But if you want to use some specific options, you can create your own configuration file based on this one (description of all options).

Frequently asked questions (FAQ)

Interface

Interface is lagging very much

Try to disable some module visualization options: Main Menu → Preferences → Modules.

I noticed the effects parameters on the right of the note, velocity etc at the top seem to be missing

These columns are hidden by default. But you can enable them - just go to the Main menu and select “Show additional columns”.

Modules, samples, effects

How to connect one module to another?

The answer is here.

Filter effect's impulse value doesn't change. When i change impulse value, it return 0

It is normal behaviour. There is no need to remember the “impulse” value. I'll try to describe the algorithm.

  1. Frequency = 1000 (for example).
  2. You set “Impulse” to 3000.
  3. Filter sets its internal frequency to 3000.
  4. Filter resets “Impulse” to 0. (0 = no more commands from user).
  5. Frequency changes smoothly from 3000 to 1000. Speed depends on the “Response” value.

How to paste sounds from another iOS apps?

  1. copy the sound in some another app #1;
  2. go to SunVox;
  3. open Main Menu (button it the top right part of the screen) → Export/Import → Paste file from system pasteboard;
  4. select folder and name for the new file;
  5. click SAVE and the file with sample from app #1 will be created;
  6. now you can load this file: go to the Modules (routing) window, open its menu and select Load.

Is there a way to make the Sampler notes less 'clicky'? When I play pure waveforms especially the clicks become really loud as it cuts off a wave at one amplitude and starts a new one at a different amplitude.

There is no automatic anticlick function in the current version of the Sampler. You should make through the Volume Envelope with 1-tick (at least) release. Also make sure that your Sampler has enough Polyphony channels. If not sure - just set it to 32 os ro.

Is there a particular bit rate/sample rate/# channels that the samples need to be in order to work?

WAV samples must be in following format: 8 / 16 / 24 / 32 (float) bits; mono / stereo; any sample rate; only uncompressed PCM data. Supported file formats: WAV, AIFF, XI, JPEG. As for JPEG, brightness of the pixels will be converted into the sound wave (pixel by pixel).

How to open the sample editor?

Please check this video-tutorial.

For multisamples, how do I set the root note of my sample?

Use the “rel.note” (relative note) parameter for such purposes.

How do I adjust multisample instruments? I see slots for multiple samples and a zone managment section in the editor, but I can only load one sample at a time?

I hope this little tutorial will help you.

Step 1. Open new empty sampler:
www.warmplace.ru_docs_sunvox_sunvox_sampler_01.jpg

Step 2. Load sample 0:
www.warmplace.ru_docs_sunvox_sunvox_sampler_02.jpg

Step 3. Sample 0 loaded:

Sound

Sound stutters or (and) freezes. How to fix?

General tips

  1. Make sure that the CPU load is not too high in your project. Check some lightweight project (tiny_tune for example).
  2. Go to the SunVox Preferences → Audio and try to change the Frequency to 48000 (or some other value if you know the native frequency of your sound card). Sometimes it helps, because the resampling (from 44100 to 48000) algorithms are not always fast enough.

Linux tips

  1. Go to the SunVox Preferences → Audio and check the Output field. If it is set to Auto - change it to some real audio output device from the drop-down list.
  2. If this does not help, try to launch the SunVox with the following command: pasuspender -- ./sunvox . This will open an exclusive access to the sound card for the SunVox.

MIDI

How to connect SunVox to another app via MIDI?

  • Windows: use LoopMIDI to create the virtual MIDI cable between the apps; in SunVox this port can be used as MIDI input (SunVox → Preferences → MIDI) or MIDI output (SunVox Module Properties → MIDI OUT).

How to split MIDI notes by channels, and send the notes from different channels to different modules?

Right now (SunVox 1.9.2) there is no direct way to do it. But it will be implemented in future updates. Now you can split your MIDI notes by the octaves (or some another pitch regions). See the example.

Other

SunVox crashing for no apparent reason

Try to clean the settings of the SunVox. Launch it from console with the following command: sunvox clearall. If you are Windows user - just run the reset_sunvox.bat script.

iOS

How can i import/export files from/to the SunVox internal storage on iOS?

There are several ways.

  1. Open SunVox → Main menu → Export/import → Wi-Fi export/import. Then follow the instructions on the screen.
  2. Use iTunes File Sharing to access the SunVox files. Launch the iTunes on your computer. Sync it with iOS device. Then find SunVox in the list of apps of your device. Select it and you will see the content of the internal SunVox storage.
  3. In some other app (for example, Mail) click on the audio file and select Open inSunVox (this function can be hidden in some menu).

How can i copy/paste audio to/from the other iOS audio apps?

  • If you want to copy the audio file (it must already exist in the internal SunVox storage) to some other app: open SunVox → Main menu → Export/import → Copy file to system pasteboard → select your audio file. Then you can open some other iOS app with Audio Copy/Paste support and do the Paste operation.
  • If you want to paste the audio file from some other app: open SunVox → Main menu → Export/import → Paste file from system pasteboard. And the new file will be created in the internal SunVox storage. Now you can load this file: Modules → Menu → Load.
