This is a phase modulating synthesizer using jack
Dependencies:
- Jack Audio Connection Kit
- Probably stuff I forgot.
Try starting the synth and type "help".
And ignore the debugging output.
Format for the .prog files:
oscillators=<number of oscillators>
<PARAM>=<value>
<PARAM>=<value>
...
controllers:
<PARAM>=<affect value>
...
defaults:
cont[<CTRL NUMBER>]=<default value>
...
velocity:
<PARAM*>=<velocity expression>
...
where <PARAM> is one of:
mod[x][y]: controls how oscillator #x modulates oscillator #y.
out[x]: output level of oscillator #x.
waveform[x]: waveform number of oscillator #x, or "440:filename.wav", where 440 denotes
the frequency of the sound in the file.
sync[x]: 0 or 1, whether this oscillator #x should be reset on every sync point or not
factor[x]: frequency factor of this osc
trem[x]: tremolo depth
trem_lfo[x]: which LFO oscillator to use for tremolo
vib[x]:
vib_lfo[x]: same for vibrato
attack[x]
decay[x]
sustain[x]
release[x]: time (in seconds) for the A/D/S/R phases of the envelope
hold[x]: 0 or 1. if set, the release phase is only entered upon NOTE OFF. if unset, release
is entered immediately after the sustain phsae.
ksl[x]/ksr[x]: key scale level/rate: affect amplitude or ADSR-phase-length depending on pitch
filter. this filter is applied to the final mix of all oscillators.
enabled: enable the high frequency cutoff filter.
env_amount: how much the filter gets affected by the filter envelope
attack
decay
sustain
release
hold
offset: cutoff frequency factor of the filter if unaffected by envelope
resonance: filter resonance, 0 .. 1
trem
trem_lfo
sync_factor: frequency of the "oscillator reset" signa;
freq.
env_amount
attack
decay
sustain
release
hold
<PARAM*> may only be "mod", "out", "filter env res off", "freq env".
<value> may be a simple expression containing numerical calculations:
Examples: 1/2, 4, 5.4*9/2
<affect value> is:
ctrl[<MIDI CTRL NUMBER>]*<value> + ctrl[<OTHER MIDI CTRL NUMBER>]*<value> + ...
<velocity expression> is:
vel*<value> + <value>, where "vel" is a reserved keyword
the "controllers:", "defaults:" and "velocity:" sections are optional.
lfo number can also be "snh", for sample and hold of random data.

about the note compiler: this generates sourcecode for a certain .prog file and
generates a .so shared object which then can be loaded. It's supposed to improve
the performance.
