How to add "Mode" to Deflector reverb?

[Riccardo Turacchio]

Hi folks!
I was checking few videos of the Afterneath eurorack version and I noticed that they implemented a really interesting feature called "MODE" that basically tune the tail of the reverb on various pitches ratios
Since the Deflector is basically a clone i presume it shouldn't be too difficult to modify the circuit to have those extra features
....maybe a small daughter board...
Anybody tried any interesting mods on this pedal?

Other interesting things of the eurorack version are the CV /expression controls
Can we implement those also on this pedal version?

The "mode" is likely different programs on the eeprom. So, new patches would need to be coded, though it's probably just a modified original reverb patch with varying pitch shifts added.
You could have any of the 3 pots controlled by CV. You need to convert the 5V or 8V euros k CV to a 0-3.3V scale and somehow switch the pot out of the loop(or just turn the pot all the way up/zero resistance) and break the 3.3v feeding it.

Converting 0-5v to 0/3.3 is done often in Arduino world and there's tons of articles and ways to do it so I won't spell it out here. I think going the optocoupler route would be better than a voltage divider route to avoid potential ground loops but do as thou wilt.
Also. However you go about it, I would add proper decoupling caps and switching to make sure you can't accidently send 8v to the fv-1 pins or the 3.3v regulator when inserting a patch cable.

"Mode" in V2 is a quantized clock.

We don't have anything like that yet, but it's possible. I do have a modulated clock (similar to what the Transmisser uses) in progress.
