This Scratch extension provides you with a set of blocks you can use to generate your own sounds.
Experiment with a sound synthesizer with blocks that control frequency and waveform, and effects like echo, pan, glide, and wah. You can use it to code your own funky electronic music or make weird new sound effects.
