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!

Great fun!

Had this app a long time now and wanted to say: it's a cool hidden gem I use to get strange synth loops. No audiobus or connectivity that I know of so recording it is a challenge but nonetheless, I do find I keep going back to it, along with all of Nic Collins' notes and writings on diy noise making. Thank you for your brilliance.

Yep cool

Fascinating sound and tone generator. Would love to be able to copy and paste some of the interesting results to manipulate in music creation apps. Very cool and mesmerizing
