Just a quick update with some pictures to show how my drone synth is coming along. The design is now finished and two of the three boards are built.

The panel layout is sorted and I’m currently putting it together on a plastic panel to see how it works out. I have a metal panel but will see how the thing performs before going wild with a drill as there’s over 100 holes.

I’m currently thinking I may try a version with different oscillators but am doing my best not to get distracted and finish this first.

I had the main voices for the synth finished a little while ago and have been working on circuits for modulation sources. I decided that one circuit in particular would be useful outside the synth I’m building as a modulation source for my beloved Juno 6.Read more »
