Filter, Envelope, VCA, and Spring Reverb based on 900 series modules.
Oscillators based on Minimoog instead of 900 series - not a big shocker, 'coz you know, marketing.
Mixer based on CP3.
This thing could replace my Ekdahl moisturizer, in addition to two analog monosynths - keeping the Monologue though. Being able to run violin/guitar through the spring reverb and filter is compelling.
