My RackMy rack is a mix of Eurorack Modular and Korg Volcas. It's always changing but usually looks something like this.
VCAThis is a crappy but functional VCA I built. While VCA does technically stand for Voltage Controlled Amplifier, it doesn't actually amplify anything.
VCFThis Voltage Controlled Filter isn't great, but it does work and I learned a lot from building it.
556 LFOThis is a dual Low Frequency Oscillator built around a 556 timer chip. While it is a bit crude it does the job just fine.
Up-DownI built this to allow me to route audio signals in and out of my modular rack. Eurorack uses a much hotter line signal than most other gear like my Korg Volcas, so it's important to shift the levels when going in or out of the rack. A signal put into an input can then be taken out in either a boosted (going into the rack) or attenuated (coming out of the rack) level.
I enjoy both playing and building Synthesizers.
