Building a dual Sympleseq
I’ve been building a couple of Sympleseq analogue sequencers from hexinverter and they’re coming on, most of the soldering is done.
Essentially, they’re basic analogue 8 step sequencers based on a 4017 decade counter, offering note on/off/reset per step. There’s an internal clock provided by a 40106 with quite a wider range, and there’s an option for externally clocking, although you’ll have to get quite close to the input voltage to clock it. I’ve not had any success yet in my brief attempt at trying to directly clock it from an MFB Dual LFO.
Here’s the rather lovely Eurorack-sized panel – hats off to Ben at resynthesis.co.uk, he’s done a great job, I’m really happy with this:
