I dunno either… its the key to aleatoric heaven
one of the best things about the venerable korg Z1 was how flexible it was with LFO routing… and the 4 ENV + 4 LFO cross modulating each other as well as other params… super nice
you can make very organic, alien animal type sounds as well as evolving drones that never repeat, etc…
and with param locks? holy shit, your brain will explode
btw - im just about to order an AK myself… so you’re in good company
