Features:
    on the front panel:
  • 4 user knobs with rainbow coloring (violet through green, on the front and folded front)
  • large text labels (front, back, and folded front)
  • number and 2d plot displays (high/mid/low can be drawn on the plots too)
  • up/down meters on both, showing the current value, high, mid, and low

  • high and low boundaries
  • midpoint curving (with option to do relative to high/low or as a fixed point)
  • s-curving (a single s-curve amount for this, but with toggles for each section to use it or not)
  • 5 curve functions

  • multiple bi/uni modes: bipolar, unipolar, negative unipolar, notes, smooth notes, and velocities
    (some are functionally equivalent but display differently)
  • sources (freely-chosen from the knobs and performance properties)
  • special behaviors for knobs with non-default sources
    (adding to or scaling the value as bi/uni, etc.)
  • level adjusters (0%-400%) with an option to choose how this is centered
  • direct invert, negate, and level adjustment on the displays

Frequently Asked Questions (FAQ) and Notes:


In no particular order:

1. Num/Plot selector isn't saved with songs (Plot gets selected)
Well, shit. Just noticed this (right before release). Maybe I can fix it, maybe not. :)
It's set up this way so the Undo feature ignores switching it.


2. Colorblind options
If this sells and there's enough interest, and/or the same with the upcoming device these knobs came from, I may give some options for these colors. It's not trivial, otherwise I'd have done it already. ;)


3. Future features?
Depending on how this does, other possible future features include: more mod inputs with some kind of mod matrix, custom-drawn-waves, etc.
