Infiknob — "infinite" range control

If you, like me, have been frustrated by the lack of fine-grained control afforded by the Organelle’s pots (or by MIDI controls in general for that matter), then you might be interested in my new patch “Infiknob.” It’s packaged up as a demo synth, which might be interesting to some, but the real point is that the use of Infiknob in the demo shows off how you can (say) control a frequency between 0.1 Hz and 20000 Hz in 0.1 Hz increments across the entire range.

The basic theory of (user) operation is that the center portion of the raw control lets you directly control the output one increment at a time, and the extremes are used to auto-increment and auto-decrement at a rate which varies with distance from the center. E.g., if you nudge just above the center range, the value will increment slowly, and as you move further towards the top of the range the rate of change increases.

I spent a while tweaking the behavior, and I think I hit on a sweet spot. Nonetheless I’m open to feedback, suggestions, etc.

I hope y’all find this useful!

The patch is uploaded on Patchstorage, here:


This is great… I think you did manage to find the sweet spot, it is easy to adjust and only takes a second to understand how it is working. Some kind of visual indicating what zone of the knob you are in could be useful, but not totally necessary since once you know how it works you wouldn’t really need it.

It would be great to use this to scrub through long sound files, such as to select start and end loop points…

I like it too…
I think id like to try it so that 9 o’clock and 3 o’clock was where the auto inc/dec starts.
so that would give you a clear point where behaviour changes, even without looking to the screen.

I did once try a similar idea, an ‘encoder’ mode,
but it lacked your centre fine tune zone… and it felt like it was drifting, so I didn’t feel ‘connected’.
but this fine tune/pot mode really helps fight that, which keeping its advantages (non-locking)

definitely makes my head whirl a bit with ideas about using the pots a bit more creatively.
I could imagine having different modes in Orac… I do remember some users talking about using ‘relative’ take over rather than ‘lock’ - but encoder and infiknob could be interesting to ‘test drive’. (*)

(*) this is actually pretty easy for me to do…
I already have some different modes changing values encoder mode (aka incremental), take over (pots) and non-takeover (used for midi), just users dont see it :wink:
so switching if over to different mechanisms could be easy enough, at least for a playground to see what feels like it works.

Thanks for the feedback. It certainly makes sense to have more visual feedback. The lack of it in this version is more about where I am in the process than anything else. (Also: This is gonna be a hard nut to crack, given how little screen real estate one has on an Organelle, and given the relative thinness of the abstraction provided by the display API.)

As for where to place the boundaries between scrubbing and auto-inc, I definitely see the draw of the visually obvious 9 o’clock / 3 o’clock. I’ll play with that boundary a bit more, and please do let me know if y’all do any similar experimentation. I’ll admit up-front that I’m a little skeptical, because that will squeeze the auto-inc range and may make for a control that’s a bit overly “jumpy.”

Just FWIW, in an earlier iteration[*] I had the speed of auto-inc increase with time in addition to the distance from center. That added complexity turned out to not particularly help given the size of the auto-inc range (and it also made the operation of the control a bit less obvious), but if the auto-inc range were reduced (per above) then a time-based rate adjustment might become a bona fide useful feature to (re)include.

[*] You can find it in the revision history of the repo (, though (sorry) I didn’t actually tag it or similar.
