I love the low pass filter on the TÅKEN and think it would be great with the Romferd. The tone control on the Fabrikat is good because it works well with all of the patches but I think the Romferd has a particular character that would suit the resonant filter well. Can you make it more resonant? Like, self-oscillating resonant? That would be amazing. I guess the thing I worry about is that if it has the same filter as Taken, they might be too similar.

Could you elaborate?

Can add an internal trimpot to adjust the amount of resonance/Q. You can make it self oscillate in a very abrasive/unpleasant way. You could probably also make it resonate with the feedback knob which would be more usable.
If I flip the enclosure vertically I'd still have room for an expression jack for feedback control. Could probably just copy the EXP specific circuitry from my KNIV pedal. We'll see how it goes. The way I'm picturing this the FEED knob would set the max available feedback (toe position of your exp pedal).

Great idea! I've had a lot of fun myself jumping between different cycle positions while the feedback is oscillating. The main reason I wish to replace the toggles with knobs is that they're less durable components. I'm now toying with something in the same realm as the knobs on the Thermea. A CYCLE knob with maybe 8 positions (normal pot) that can also be set by a random cycle length generator (microcontroller). Wouldn't add a lot of extra work/circuitry.

I've ordered a prototype PCB for the updated Romferd. The circuit is very similar to the original:
* TONE switch is replaced by a knob that sets the cut off frequency of a low pass filter. The filter resonance can be tuned by adjusting an internal trimpot.
* CYCLE switch is replaced by a knob that sets the delay time. As suggested in this thread the delay time is locked to step (4 steps). Minimum delay time remains the same as that's just how the PT2399 works.
* Added an expression jack for feedback adjustment. Haven't tested this yet.
* Top mounted jacks on an upright 1590BB (same size as before).
Hopefully the prototype works as intended and I'll be able to start production of a smaller batch in November.
