'Here's a clip of the performance synth I built over the summer of 2011. I just added an awesome rhythm section prototype circuit based on Eric archers amazing andromeda drum modules. The drum sequencer is basically just two CD4089 binary rate multipliers. I added a CD4024 binary counter for making more complex rhythm sequences and also added a CD40106 for inverting various signals to put everything in phase.'
