May l first thank all who gave me advice and help on my last post.
I have been looking at Sam’s videos on the Sega Mega Drive synth, it looks expensive to build but worth it. The problem is that l can’t find a schematic or any details on how to build it, has any plans on how to build this synth been posted?
Any help would be appreciated, many thanks.

It’s basically one big MIDI controller for a [genMDM](https://catskullelectronics.com/genmdm), using an Arduino Nano and a number of 4067 muxes (e.g. [this one](https://www.sparkfun.com/products/9056)) to sample a ton of potentiometers. Code and more details here:

(If you haven’t used Arduinos for MIDI before, I’d strongly suggest starting with something much smaller, like one Nano and a couple of potentiometers.)

Hi Fredrick, yes l have seen the Catskull Electronics gen MDM, l will take your advice and start with a small project first. But is there a wiring diagram for the panel and strip boards, l think Sam says he will produce one, but l appreciate that he has been working full time in the new premises.
