Hi there, I'm new to the group. Just bought my first Doepfer product, the R2M ribbon
 controller, which I have been using with my Modcan and Arrick (dot com) systems. I'm very
 please with it. Works great with both MIDI and CV.
 The A-107 Multitype Morphing Filter and the A-113 Subharmonic Generator have caught
 my interest. I'm considering putting together a small Doepfer system based around these
 modules.
 Has anyone used these How do they sound Advice Suggestions
