Hi everyone,

Been searching high and low for tutorials on using the Doepfer A-171-2 VCS Slew Processor/Generator Serge clone module that came with my Doepfer A100 Basic modular system but cannot find anything on how to patch it and the manual is less than useless from Doepfer. Any ideas? It has Input, CV increase, CV decrease, exp CV, trig, cycle and end/output patch points.


Well, given that it's a variant on Ken Stone's revision of the Serge USG, looking first at THIS might be useful: https://www.elby-designs.com/webtek/euro-serge/es114-universal-slope-generator/es114.htm Also this, from Serge's original docs: https://serge.synth.net/documents/datasheet/DSG.jpg

Thanks Lugia,

I've been enjoying the Doepfer A100 modular system so far. I did order a few more modules to fill out the case and they should arrive next week: a Borg filter, quad vca, quad EG, and Richter anti-oscillator as well as Batumi quad LFO!

Hi sacguy71,

Have you gotten a handle on this module yet? Did you find any useful tutorials? How do you find yourself using it?
