tildearrow Sound Unit instrument editor

this instrument editor has two tabs.

Sound Unit

for sample settings, see the Sample instrument editor.

the differences are:

  • the lack of an "Use wavetable" option
  • the presence of a "Use sample" one
  • the presence of a "Switch roles of frequency and phase reset timer" option. when enabled, this writes frequency to the phase reset timer register rather than the frequency register
    • this may be used to create sync-like effects.

Macros

  • Volume: volume sequence.
  • Arpeggio: pitch sequence.
  • Duty/Noise: waveform duty cycle sequence.
  • Waveform: select waveform.
    • 0: pulse wave
    • 1: sawtooth
    • 2: sine wave
    • 3: triangle wave
    • 4: noise
    • 5: periodic noise
    • 6: XOR sine
    • 7: XOR triangle
  • Panning: stereo panning sequence.
  • Pitch: fine pitch.
  • Phase Reset: trigger restart of waveform.
  • Cutoff: set filter cutoff.
  • Resonance: set filter resonance.
    • values that are too high may distort the output!
  • Control: filter parameter/ring mod sequence.
    • band pass: a band-pass filter. cutoff determines which part of the sound is heard (from bass to treble).
    • high pass: a high-pass filter. higher cutoff values result in a less "bassy" sound.
    • low pass: a low-pass filter. the lower the cutoff, the darker the sound.
    • ring mod: enable ring modulation with previous channel.
      • note: square wave goes from 0 to volume, so in that case it acts more like amplitude modulation.
  • Phase Reset Timer: sets the phase reset timer.
    • if the "Switch roles of frequency and phase reset timer" option in the Sound Unit tab is enabled, this macro controls the frequency register instead.
