The AHR envelope was exactly what I was searching for!

Agreed, simulating those incompatibilities would be pointless endeavour! I bought the LPG to get 'buchla bongo' which it does perfect, but also use now to get '303 acid bass' or 'deep sine bass' so is good multi purpose filter. And your right with the Forbidden Planet reference, this was to do some 'krell patches'

Another useful module I found was https://store.cherryaudio.com/modules/civil-unrest - a good simple interface to get 'controlled random values', I've also been using https://store.cherryaudio.com/modules/indent for wave folder - but control is a bit limited so will also be looking at the Monkey Business https://store.cherryaudio.com/modules/foldr in future.

Thanks for the suggestions I will definitely take a look at the Zeroscillator for oscillator next time round
