BUGS

  • ! ! ! Check for 'TODO:' in files
  • Pattern instances can have a negative beat_start but should not

THINK ABOUT

USER REPORT

  • New pattern already filled and un-editable
  • Crash on adding pattern / synth -> Crash from ArrayExt when freing previous ptr while it should not It should be NULL but can't find why it's not.
  • Note effects not saved !

SELF REQUEST

  • Mod will recording as CV ?
  • CV Fx
    • Note effect 'Mxy' set synth CV channel x to y (0v to 10v) OR
    • Note effect 'Mxx' set synth CV channel 0 to x (0v to 9.9v) OR
    • Both ? 'Mxx' & 'mxy'

USER REQUESTS

  • Midi input

    • Midi input set velocity
    • Midi polyphonic input

  • Information / Help display (bottom left)

    • Pattern mode: Active column / cell / note effect information
    • Timeline mode: Current time & total time (in beats)

  • Shortcuts

    • Transpose shortcut (ctrl + arrows = semitone ; maj + arrows = octave)
    • Use num pad to enter numbers
    • Play / pause shortcuts

  • Slew limiter to panning & velocity in synth module (avoid click)

  • Synth module needs CV output to be connected even with mapping

  • Polyphonic rotation rotate to find next available channel (if possible)

  • Pattern instance selection + edition

  • Auto-scroll playing timeline

  • ! ! ! Selection + multiple edition ! ! !

  • ? ? ? FX controlling pattern length ? ? ?

  • Glide allowing effects ? -> Useful to have chance or random note / octave

  • What happens to overriden notes / voices when synth is used with many notes ?

  • Tuning

    • Multiple tuning - switch between them (via CV ?)
    • Tuning view

Effects

  • Axx Amplitude random (xx: noise amplitude) Multiply base amplitude by noise (noise can only make it lower)
  • Pxx Pan random (xx: pan amplitude) Add noise to base panning (bipolar noise)
  • pxx Pitch (micro) random (xx: pitch amplitude)
  • txx Tuning (micro) fixed (xx: pitch amplitude up to 1 semitone) xx = 0 : Note n xx = 99 : Note n + 1 Transition from 0 to 99 depends on temperament table Microtonal + MPE
  • Dxx Delay random (xx: delay amplitude)
  • Oxy Octave random (x: mode y: amplitude) x = 0 : -+ offset x = 1 : + offset x = 2 : - offset
  • Mxy Note random semitone (x: semitone tone 1st offset y: 2nd offset) Peek random note between [base note], [base + x] and [base + y] x & y being semitone offset Can be cumulable
  • Vxy Vibrato (x: speed y: amplitude)
  • Txy Tremolo (x: speed y: amplitude)
  • Cxx Chance keep (xx: chance) Keep previous running note on if chance does not occur
  • cxx Chance stop (xx: chance) Stop previous running note even if chance does not occur
  • Rxx Ratchet / Retrigger (xx: retrigger interval) ? (x: amp fade y: interval) x<5 : decrease | x>5 : increase | x=5 : static y represents the interval between retriggers
