Created by Marcus Dunn: https://github.com/lonesoulsurfer/Delay_Modular_Synth

Arduino based mono delay (not clockable) with six different time settings and an FX switch.

Adding delay to any synth can add fantastic depth to the sonic soundscape. This build uses an Arduino Nano to create a digtal delay that can be used on a modular synths or as it's own stand along synth. It's an easy build with minimal components needed and the finished module sounds great!

The original schematic (see below) had some additional features which were removed as they didn't sound great. Also changes to the values of 2 capacitors connected to the input and output audio sockets as the module was getting too much feedback. This doesn't effect the delay at all and removes most if not all of the noise.
