Doepfer A-166

Effectively four circuits packed into this 8HP logic module. There are two logic circuits for combining gates in various ways. The other two circuits are a couple of logic inverters at the bottom. Highly versatile and although I have been using this module for more than a year I still find new ways to use it.

Generally I use it to create rhythmic patterns. Sometimes just as a gate or trigger combiner. I like to generate rhythm with the logic circuit and inverted to get the exact opposite then use these two gates to control two VCAs panned to either side of a stereo image to get rhythmic stereo bouncing. The inverters I also find useful for flipping an out of sync gate to bring everything back into time. Plus the inverters can be use simply as a voltage source with nothing plugged into the input and the output routed through an attenuator for added control.

Eight LEDs let you know exactly what this module is doing ...and as well as interesting sounds I love flashing lights too!

Since the module doesn't genarate any sound I have knocked a star off "sound".

I would say essential for any system.
