Hello @Tchnondz,

It looks like 510 doesn't have its own envelope generator built in, so you will need a separate module for that if you are going for a more traditional subtractive synth voice. You can still send the meloDICER's gate out to the mod inputs on the 510's filter and VCA, but it will be very abrupt sounding. You will probably want a couple of envelope generators (and maybe an LFO or two) to really get things moving in the 510. That'll give you a lot more sound shaping ability and variety of sounds out of the 510. Something like Intellijel's Quadrax would be a great option for this, in my opinion.

I hope some of that helps!
