  • Launch of CESYG

    A new year... a new synth adventure!! I'm pleased to say that my new venture in synth design is now online. The aim is to give a more formal structure to my ideas, with a wider range of parts, and also ready-made modules. The first of CESYG's fruits is now available: 3.5mm jack board. I've also started a blog to accompany this new project. Early days, but more to come!!

  • Synth Modules

    The first daughter card for the 3-channel mixer is now released. The 3-channel voltage controlled mute adds three channels of voltage-controlled mute to each of the mixer input channels. Each mute circuit has a "mute" LED, CV input with a 1.5V threshold suitable for most gate signals, and supports both momentary push buttons and standard SPDT toggle switch.
