RISCy is a drag and drop synthesizer puzzle full of sonic perturbation. You live code via the limited instruction set in the lower part of the interface; drag out tokens to the top area to build your synth graph, drag a token back off the top area to remove it. Each token has an aural consequence, and some special tokens also change the nature of the hidden graph connecting active tokens; puzzling out these relationships is part of the fun. You'll be able to make lots of noisy sounds as well as generative sequenced patterns. Press ! to clear the graph and reset; press ? to get a random starting point. Download RISCy if you are open to stranger computer music sounds, and avoid it if you just want diatonic melodies and piano sounds!
