Synthmulator

Synthmulator is a virtual world simulator (aka video game) where you are alone in a room with the PROTO-1, a modular synthesizer setup, and a bunch of cables. It is not a sound desing tool, but you might be able to design sounds with it; approach it as a toy.

The PROTO-1 is an eurorack system with 2 LFOs, 2 VCOs, 2 envelope generators, 2 filters, a sequencer, an oscilloscope, a 2-channel splitter, a 4-input mixer and a speaker. Everything fits inside a manageable case with all you need to start experimenting with sound synthesis.
