Hi Eexee,
If you have to put the attack up to 5-6 then I am afraid you might have another issue going on, that shouldn't be the case. I don't know which Doepfer ADSR you have, if it's just the A-140, the one I am using too, then make sure that how often you trigger your ADSR should be roughly in the rhythm of the ADSR itself as well, that's how I call that for myself, not sure how to put this properly under words.
What I mean with that is that if you offer very fast gates to a (Doepfer) ADSR/EG then make sure you put the ADSR in fast mode, i.e. put that time range switch to L (low time, so high speed) or M (medium time/speed) but not H (high time thus low speed) and visa versa so if you provide a slow trigger set the ADSR to H (high time, thus slow speed). Once that's corresponding to each other than I don't think there is a need to put the attack so high to avoid clicks.
Let me know if that works out for you and good luck. Kind regards, Garfield.

I have the A-141-2 VCADSR/LFO unit. That's the worst case scenario, I suppose. This has three modes, x1, x10, and x100. Those seem to be like S/M/L on my other ADSR (Soundforce Dual). Patching a basic sine through a VCA and using this module to attenuate the amplitude, at x1 I need at least 3-4 to crop out the clickies, at x10 I need 2-3, and at x100 I only need 1-2 -- though all these require at least equivalent delay times. I guess that's really not so bad, though some signals fare better than others it seems to me, and in fairness, I think I do confuse the x1/x10/x100 setting at times, and haven't always chosen the most appropriate one.
That said, with my Soundforce Dual ADSR I barely have to have any attack to elimate clickies on the same wave, no more than 1 in some cases, regardless of the setting (S/M/L - Lin/Exp). I feel like I generally have more problems with clicks/pops from the Doepfer one.
I'd actually thought about selling off the Doepfer one, since I mainly use the Soundforce now, but the A-141-2 does have CV ins for each stage of the envelope with -5 to +5 attenuverters for each (which I quite like), EOA and EOR triggers, and can be patched in ways that turn it into a crazy sound source. If it could get a couple hundred for it I'd probably list it, but you can get them new for like $180-190, so I'd probably have to settle for $150 or so before shipping/fees. It's handy enough to keep around for now, though I might eventually sell/replace with a different type of envelope generator.
