Sound2Note module

Post by queries »

Sound2Note could work like this:

The absolute value of the incoming waveform is mapped to a configurable pitch range from 0x0000 to 0x8000. At a configurable frequency, this is converted to SP (set pitch) note events that are sent to downstream modules.

"Start pitch" and "End pitch" controllers - 0x0000 to 0x8000 as noted above... can be reversible like MultiCtl and Velocity2Ctl etc.

"Active" yes/no controller - defaults to "yes" - when set to "no", it will stop generating new notes. (Will not send a note-off though; combine with setting "note off immediately" to yes to stop generating notes AND note-off any currently playing note)

"Velocity" controller - range 0-128; default 64 - velocity of generated notes.

"Freq" and "Frequency Unit" controllers - similar to LFO, controls rate at which incoming audio is sampled and note events are produced.

"Set Phase" controller - similar in function to LFO; you can set to a specific phase point in the sampling frequency; always rests at zero.

"Hold notes" on/off controller - when on (default), if sampled value is same as previous, no new note event is sent; when off, note events always sent even if sampled value is same as previous.

"Note off at zero" on/off controller - when on (default), if sampled value is 0, a note-off event is emitted; when off, a set-pitch of 0x0000 is emitted.

"Note off immediately" on/off controller - when set to on, immediately sends a note-off event; always resets to off (like "set phase" does).

--

Possible use case would be LFO-driven arpeggiators, when combined with a note-transforming metamodule (see other feature request):

Amplifier w/ DC offset > LFO > Sound2Note > Note Transformer > Synth

The note that was playing would be determined by the LFO's frequency, and the rhythm would be determined by the Sound2Note's frequency.

This might be cool for generating random music without using any if the effects commands. I could imagine using this with a couple generators to drive an entire patch.

A little addition to the feature request... the absolute value of the second audio input could be translated to velocity.
