Here's the full list:
| Code | Python | Type-range | Notes |
|---|---|---|---|
| a | amp | float 0-1+ | use after a note on is triggered with velocity to adjust amplitude without re-triggering the note |
| A | bp0 | string | in commas, like 100,0.5,150,0.25,200,0 -- envelope generator with alternating time(ms) and ratio. last pair triggers on note off |
| B | bp1 | string | set the second breakpoint generator. see breakpoint 0 |
| b | feedback | float 0-1 | use for the ALGO synthesis type in FM, or partial synthesis (for bandwidth) or for karplus-strong, or to indicate PCM looping (0 off, >0, on) |
| C | bp2 | string | 3rd breakpoint generator |
| d | duty | float 0.001-0.999 | duty cycle for pulse wave, default 0.5 |
| D | debug | uint, 2-4 | 2 shows queue sample, 3 shows oscillator data, 4 shows modified oscillator. will interrupt audio! |
| f | freq | float | frequency of oscillator |
| F | filter_freq | float | center frequency for biquad filter |
| g | mod_target | uint mask | Which parameter modulation/LFO controls. 1=amp, 2=duty, 4=freq, 8=filter freq, 16=resonance, 32=feedback. Can handle any combo, add them together |
| G | filter_type | 0-3 | 0 = none (default.) 1 = low pass, 2 = band pass, 3 = hi pass. |
| I | ratio | float | for ALGO types, where the base note frequency controls the modulators, or for the ALGO base note and PARTIALS base note, where the ratio controls the speed of the playback |
| L | mod_source | 0 to OSCS-1 | Which oscillator is used as an modulation/LFO source for this oscillator. Source oscillator will be silent. |
| l | vel | float 0-1+ | velocity - >0 to trigger note on, 0 to trigger note off. sets amplitude |
| N | latency_ms | uint | sets latency in ms. default 0 |
| n | note | uint 0-127 | midi note, sets frequency |
| o | algorithm | uint 1-32 | DX7 algorith to use for ALGO type |
| O | algo_source | string | which oscillators to use for the algorithm. list of six, use -1 for not used, e.g 0,1,2,-1,-1-1 |
| p | patch | uint | choose a preloaded PCM sample, partial patch or FM patch number for ALGO waveforms. |
| P | phase | float 0-1 | where in the oscillator's cycle to start sampling from (also works on the PCM buffer). default 0 |
| R | resonance | float | q factor of biquad filter. in practice, 0-10.0. default 0.7 |
| S | reset | uint | resets given oscillator. set to > OSCS to reset all oscillators, gain and EQ |
| T | bp0_target | uint mask | Which parameter bp0 controls. 1=amp, 2=duty, 4=freq, 8=filter freq, 16=resonance, 32=feedback (can be added together). Can add 64 for linear ramp, otherwise exponential |
| t | timestamp | uint | ms of expected playback since some fixed start point on your host. you should always give this if you can. |
| v | osc | uint 0 to OSCS-1 | which oscillator to control |
| V | volume | float 0-10 | volume knob for entire synth, default 1.0 |
| w | wave | uint 0-11 | waveform: [0=SINE, PULSE, SAW_DOWN, SAW_UP, TRIANGLE, NOISE, KS, PCM, ALGO, PARTIAL, PARTIALS, OFF]. default: 0/SINE |
| W | bp1_target | uint mask | see bp0_target |
| x | eq_l | float | in dB, fc=800Hz amount, -15 to 15. 0 is off. default 0. |
| X | bp2_target | uint mask | see bp0_target |
| y | eq_m | float | in dB, fc=2500Hz amount, -15 to 15. 0 is off. default 0. |
| z | eq_h | float | in dB, fc=7500Hz amount, -15 to 15. 0 is off. default 0. |
