Unless I am just doing something very wrong, which is surely possible : )

if I go into the 'manipulate gene' section, and twist either the vol attack or mod attack knobs - while the knobs turn and the dna L-R slider moves, neither envelope changes. Same from different patches. Can't hear any audible difference either. Doesn't matter what I adjust the other envelope settings to, attack refuses to move for vol or mod. I am using mouse to drag them around (no midi controller).

All the other knobs in those sections appear to work fine. (haven't dug into the others yet, but adjusting basic attack & release are usually things I tweak alot)

again, win 10 x64, vst3 far as I can tell

thx again!

Just to double-check that this is not just a misunderstanding, env_atk + mod_atk (and env_dcy + mod_dcy) shape the attack (and decay) segments; they don't affect attack times. If you want a slower attack, try the env_tilt parameter.

The genes in Synplant are a little unconventional because they are meta-parameters that generate the underlying synth parameters for the audio engine. They are balanced so that they generate interesting sounds with almost all settings.
