Behringer Pro 800, Dual Phase, Arp 1036 S&H for Pro 800 Filter CV in!
at 2.35 the internal S&H is routed to the filter cutoff.

yes!

Very nice! Did you do any fancy tricks to get the filter CV working? Mine only modulates a tiny bit (with the mod amount turned up to 999).

[@Ebotronix]

Thanks! I use the full Synthtribe value but it doesn't work very well . at 2.35 I use the internal LFO but without the possibility to sync the internal LFO it makes no sense.

@@Ebotronix yeah, hope they can sort this stuff out in a firmware update.. Cheers :)

[@Ebotronix]

@dudfaz I thing it does't work with a Firmware update .
please have a look at Maffez Pro 800 mods:
Increase external filter CV mount: Nt sure what Behringer were testing this with but even with a 3340 VCO I get only say, mild filter cutoff control. I wired some 3.3k resistors across each R340 (23.2k) and am fine with the max amount now.

​@@Ebotronix Thanks for the info. Interesting theory about the firmware - I wonder if they somehow sacrificed the CV for the extra filter EG.. but seems it's impossible to revert to a previous version to check. Yeah, I saw that from Maffez - but I don't want to mess around with it in case they fix the problem in a future update. Fingers crossed! Cheers

Thanks for the demo.
I tried to modulate Pro 800 FILTER CV IN with Hydrasynth, but it seems to increase resonance only (up to very loud, cv works). Filter frequency doesn't seem modulated. :(
Edit : I was also sending midi HS knob, resonance CC ! So I made it work. The range is deceiving indeed...
