A-135-5 Polyphonic Mixer + Suboctave Generator

Doepfer A-135-5

An unexpected yet incredibly creative combination of functions, Doepfer's A-135-5 is a polyphonic mixer with integrated frequency dividers for suboctave signal generation. Featuring three channels (A, B, C) with four inputs each (1, 2, 3, 4), the A-135-5 allows you to easily sum together multiple outputs from multi-channel polyphonic modules, such as the A-111-4. Set the levels of channels A, B, and C manually or with control voltage, and use the mute switches to optionally bypass them entirely. As a bonus, the inputs of A normal down into B with a frequency divider in between, giving you a free square wave sub-octave to blend in with up to two other sources. If you're going all in on Eurorack polyphony, then the A-135-5 from Doepfer should be on your radar.
