I also would like to see a simple reverb (or delay).
Microfreak is also about mobility/portability(USB powered etc.) so a simple reverb algorithm would be perfect if possible(like in the volca modular e.g.)
I have a Microfreak because I can take it with me in my small backpack and a USB power bar.
I don't want to carry also an additional pedal to have this effect.
Of course, there are a lot of perfect reverb/delay pedals and I also own some, but again I would like to keep it simple.
But yes, the only question is how much CPU/DSP power it needs.
The control of the FX I could imagine to use e.g. SHIFT + TYPE for the FX type and SHIFT + WAVE /TIMBER / SHAPE for e.g. wet/dry / Para1 / Para2 etc.- again - only if such routings are possible...
