As you can see, there are two sound engine formats in SunVox. Let's look at them in detail.
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.
The SunVox window is divided into the several rectangular areas (windows):
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.

The SunVox project consists of the following parts:
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:
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||…|
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:
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
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 frames 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 speed (number of ticks per line) of playback. Valid values for speed setting are 1 - 1F (1 - 31 in decimal). Values above 1F (31 in decimal), represent a modified speed based on beats per minute, where 4 lines are 1 beat. 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%)).

You can use controllers with number 80+X to send MIDI Control Change command. Where the X is MIDI Controller Number.
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 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
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 is a basic element of the SunVox. There are several types of modules:
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:
Reconnection removes the previous connection.
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:
Some modules have a “Mode” parameter with the following possible values:
If the CPU of your device is too slow for some SunVox project (app stutters and hangs), you can use the following tips:
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.
Playback speed is defined by the following parameters:
Generator with 32 double alias-free oscillators with internal 12/24dB filters, exponential envelopes and smooth parameters changing.
Video: Virtual Analog Generator
Drum synthesizer with variety of predefined sounds.
Distribution of sounds:
This synth is based on frequency modulation. It operates on an internal sampling frequency 44100 Hz. Abbreviations: C - carrier; M - modulator.
Basic oscillator with different waveforms and volume envelope.
This module can receive the incoming signal and use it for the phase modulation. To do this, connect any other audio source to the input of the Generator, and that source will affect the frequency of the Generator. And don't forget to set Phase Modulation controller to non-zero value.
Available local controllers: Type; Pan.

Signal amplifier with various settings.
For example you can split a stereo audio input into the left and right channels with this module:
Explanation of compressor settings (taken from here)
This controls the amount the compressor reduces the volume when activated (the threshold is the point where the compressor is activated).
In SunVox it is measured by a percentage, but in other DAWs it is called “Ratio”. They have the same effect, it's just that the measurement is different (Example: 50% vs 2:1 ratio)
I have a kick and a synth going to a compressor. I set the sidechain input to the kick module, so when the kick's volume goes over the threshold, the sidechain compressor activates and decreases the volume of the synth.
Now let's get into some numbers.
Suppose the slope is set to 50%. If my kick goes 2 decibels over the threshold, the compressor will reduce the volume of the synth by 1 decibel (2*.5=1). If my kick goes 4 decibels over the threshold, the compressor will reduce the volume of the synth by 2 decibels (4*.5=2). If I want less volume reduction, I reduce the slope. So now let's set that slope to 25%. If my kick goes 4 decibels over the threshold, the compressor will reduce the volume of the synth by 1 decibel (4*.25=1).
This value controls how long the compressor takes to reduce the audio when activated. Note that (when activated) the compressor will IMMEDIATELY start to reduce the volume. It's the attack that tells it how long to take to get to the full reduction.
Suppose I have a kick that lasts 32 milliseconds and exceeds the threshold by 4 decibels. My slope is set to 50%, and the attack time is 10 milliseconds. The volume of the synth connected to the compressor will be reduced by 2 decibels (4*.5=2) over 10 milliseconds. The biggest change in volume will be at the end of the attack.
Here is a more visual example of the effect of the compressor on the synth:
--- = Volume of synth Threshold = 2 db Assuming the synth's volume starts at 8 decibels: A-------- <==(kicker exceeds the 2 db threshold by 4 db, sidechain compressor is activated and begins reducing the volume of the synth) B------ <==(the synth's audio is reduced by 2 db 10 milliseconds after being activated at A. The volume of the synth is now 6 db)
Note that the length of the kick doesn't matter (when changing the volume), its volume just needs to exceed the threshold to activate the compressor (you could have a kick that is 1 millisecond long and it'll still activate it). To sustain the compression, your kick will have to stay over the threshold for a longer period of time.
This controls how long the compressor takes to return the audio to its original volume after the attack (it's essentially the same as attack, but backwards).
Using the example above (from the attack portion of this post), let's set the release to 45 milliseconds. After the sidechain input audio stops being over the threshold, the release returns the synth to its original volume over 45 milliseconds.
--- = Volume of synth Threshold = 2 db Assuming the synth starts at a volume of 8 decibels: A-------- <==(kicker exceeds the 2 db threshold by 4 db, sidechain compressor is activated and begins reducing the volume of the synth) B------ <==(the synth's audio is reduced by 2 db 10 milliseconds after being activated at A. The volume of the synth is now 6 db) C-------<==(the kick's volume has decreased and is no longer over the compressor's threshold, which triggers the release) D-------- <==(45 milliseconds AFTER C, the audio is back to its original volume)
What your attack/release/slope values are depends on what you want. If you want a hard, pumping sidechain compressor, try an attack of 10 and a release of 45, then adjust the slope until it really pushes the synth down (just before it hits the bottom of the waveform box). This will reduce the volume over 10 milliseconds, then return it to its original state 45 milliseconds after the sidechain input audio stops being over the threshold.
If you want the kick to be louder, but don't want it to affect the compressor, you can link it to a distortion module (which is linked to out) and increase the volume (of the distortion module). The sidechain just uses the input you give it. The sidechain compressor functions the same as a regular compressor, the only difference is that the sidechain asks for an input instead of affecting everything linked to it.
DC blocking filter.
Maximal length of the delay is 1/64 second.
Maximal delay length: 4 seconds.
State Variable Filter.
In HQ mode the Filter is double-sampled. In LQ mode the Filter is 2x faster, but with the following consequences:
High quality IIR filter. Much more slower than the Filter.
LFO - Low Frequency Oscillator.
This effect is for repeating small pieces of input sound.
Video: Loop Module
Amplitude or Phase modulator. First input = Carrier. Other inputs = Modulators.

Reverberator with DC Blocking Filter.
This filter was designed to simulate the vocal tract of a human.
In simple terms, WaveShaper allows you to change the shape of the input signal. Default shape is linear (no changes; play the original signal).
In math terms, WaveShaper is the expression y = f( x ); where y - output; x - input; f - function with graph which you can see in the WaveShaper interface. The horizontal axis of the graph is Input. The vertical axis of the graph is Output.
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 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.
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.
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:
With this module you can control multiple controllers at once.
Video: MultiCtl Module
Sends the incoming events (Note ON, Note OFF, etc.) to any number of connected modules. So with the MultiSynth you can play a large number of synths simultaneously by pressing one note only.
This module converts the incoming notes to the controller values (in some another connected module).
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
This module converts the velocity parameter of the incoming notes to the controller values (in some another connected module).
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).
In most cases, you should not change this file manually, because the main settings are available in the SunVox Preferences window.
SunVox takes its configuration from the sunvox_config.ini or sunvox_config.txt file. This file must be placed in one of the following directories:
Typical sunvox_config.ini file looks like this:
// Remove the '//' symbol to enable (uncomment) the string. // Uncomment this option if you want to launch SunVox without the window (pure console mode without UI): //nowin // Window width and height: width 800 height 600 // Use this option to set max number of frames per second: // ( less value - less CPU usage ) //maxfps 30 // Uncomment these options to hide scopes and levels (i.e. for slow devices): //no_scopes //no_levels // Modules size: //synths_min_num 8 //synth_max_xsize 100 //synth_min_xsize 32 //synth_xsize_divider 8 //synth_ysize_multiplier 80 // Undo buffer size (in kilobytes): //undosize 2048 // Uncomment this option to rotate the screen (device dependent): // ( example of usage: rotate 90 //turn the screen by 90 degrees ) //rotate 90 // Uncomment this option if you want fullscreen mode: //fullscreen // Uncomment this option if your device has touchscreen without pen (stylus), // or if you just want a large buttons: //touchcontrol // Sound buffer size (in frames): buffer 4096 // Audio device name: // * name examples for ALSA (Linux): "hw:0,0", "hw:1,0"; // * name examples for other audio systems: "0" - first device; "1" - second device; //audiodevice hw:0,0 // Audio driver name (alsa, oss, sdl, dsound, mmsound, asio): // * alsa - ALSA (Linux); // * oss - OSS (Linux); // * sdl - SDL (Linux); // * dsound - DirectSound (Windows); // * mmsound - oldest audio API, slow, but compatible with all Windows and Windows CE devices; // * asio - ASIO (Windows); //audiodriver alsa // Sample rate (audio frames per second; minimum - 44100): frequency 44100 // Video driver name on Windows CE: // * gapi - default; requires gx.dll installed in your system; // * raw - raw hires framebuffer; not supported by some devices; // * gdi - compatibility mode; slow but universal; //videodriver gapi // Force UI optimization for Pen/Mouse control: //pencontrol // Display pixels per inch: //ppi 160 // UI scale factor (normal=256): //scale 256 // Pixel size: //zoom 2 // Uncomment the "theme" option to use the custom color themes: // (four base colors defined by c_0, c_1, c_2 and c_3 options) //theme c_0 #000000 c_1 #101010 c_2 #808080 c_3 #FFFF00
Q: Interface is lagging very much.
A: Try to disable some module visualization options: Main Menu → Preferences → Modules.
Q: I noticed the effects parameters on the right of the note, velocity etc at the top seem to be missing.
A: These columns are hidden by default. But you can enable them - just go to the Main menu and select “Show additional columns”.
Q: How to connect one module to another?
A: The answer is here.
Q: Filter effect's impulse value doesn't change. When i change impulse value, it return 0.
A: It is normal behaviour. There is no need to remember the “impulse” value. I'll try to describe the algorithm.
Q: How to paste sounds from another iOS apps?
Q: 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.
A: 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.
Q: Is there a particular bit rate/sample rate/# channels that the samples need to be in order to work?
A: WAV samples must be in following format: 8 / 16 / 24 / 32 (float) bits; mono / stereo; any sampling frequency; 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).
Q: How to open the sample editor?
A: Please check this video-tutorial.
Q: For multisamples, how do I set the root note of my sample?
A: Use the “rel.note” (relative note) parameter for such purposes.
Q: 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?
A: I hope this little tutorial will help you.
Q: Sound stutters or (and) freezes. How to fix?
Q: After i export the session into soundfile, where can i open this file in iOS device?
A: There are three ways.
1) 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.
2) Open SunVox → Main menu → Export/import → Wi-Fi export/import. Then follow the instructions on the screen.
