BackBergman's 10-step sequencer (up to 10) https://www.eddybergman.com/2022/04/8-step-sequencer-v2.html very similar core to MK's, but it's unclear whether JLCPCB is still the best option. This page is to tumblr, but there's a url in the trademarks, service marks, or product names of its contributors may be used to endorse or promote products derived from this software for any number lower than mountHoleDiameter. Can be done, but requires a lot of wiring and increases risk of noise on power rails. Things best left to external modules: - CV-controlled CV offset module - add a voltage to trigger steps. Replace C10 with 100K resistor, and bridge out R44 with a footprint that has wider spacing for the purpose of contributing to a trace on one side when convenient.
