TIMBRE POT : sets Channel. In the absence of graduation, timbre variation may help
(Wave Form 1 low = CH1, WF 1 High = CH2, WF 2 Low = CH3, etc...)
MUTE BUTTON:
Sends ALL NOTE OFF on selected channel and stay in mute until it's pushed again.
AUDIO:
Audio processing from antennas to output jack, including pots, LEDs and button functions, is exactly the same as in open theremin V3.
### What can I do to get a theremin like glissando?
Set pitch bend range of the theremin with a high value (12 semitones or 24 semitones).
Activate picth bend and set pitch bend range of the theremin with a high value (12 semitones or 24 semitones).
Set pitch bend range of the synth with the same value
Closest to real theremin settings (pitch bend range = 24 semitones):
1. Set pots like this: Volume = Min, Pitch = Max, Register = Max, Timbre = Midi channel.
2. Push button for two seconds.
3. Then set pots as for audio (Example : Volume = Mid, Pitch = Mid, Register = Wanted octave, Timbre = any)
4. Play (you can mix synth and audio if you want)
### If I do not trigger with the volume hand it also seems to trigger a new tone with the pitch antenna. Guess this is how MIDI works.
Yes, with settings above, if you trigger a note (with volume loop) and go in one direction (with pitch antenna) a new note will be triggered after two octaves.
This is a limitation of midi. Maybe some synth can perform pitch bend on more that 2 octaves but none of mine does...
### Tweak
In the following lines of application.cpp:
// Set key follow so as next played note will be at limit of pitch bend range
When legato mode is activated if you trigger a note (with volume loop) and go in one direction (with pitch antenna) a new note will be triggered at the limit of pitch bend range.
The "-0.2" could be changed into another value from "0" to "-0.5" depending on how good you are to reach center of the note that you play. "0" is for very good players. "-0.5" is very permissive and generates note toggling in 1 semitone mode. "-0.2" is the limit where my favourite chromatic tuner's green LED turns off (and it is OK for me).
Legato mode is used as a workaround for a limitation of midi (max 24 semitone pitch bend). Maybe some synth can perform pitch bend on more that 2 octaves but none of mine does...
