The SID 8-Bit Groovebox Synthesizer from Mode Machines is a hardware synthesizer based on the 8-bit Commodore 64 SID chip. It features an integrated 16-step sequencer as well as access to 24 separate parameters designed to control and tweak your sound. The 24 parameters can be modulated through hand-drawn graphs on the downloadable librarian software. Over 100 patches and over 50 wavetable drums sounds can be set up and stored in SID. 5-pin DIN MIDI input and output allows you to play SID with an external controller.
