Welcome to the Sound Stage
Plumbmonkey Music Sandbox
Two instruments from the Ghost Circuit sound lab, running entirely in your browser.
Make a beat, play a riff — no install, no sign-up.
Drum Machine
Program 16-step beats across eight synthesized drum voices — kick, snare, claps, hats, toms and cowbell. Tempo, swing, save & load, and export your loop to WAV or MIDI (plus one-shot samples).
Soft Synth
Play with your mouse, touch, or computer keys across a shiftable C2–C6 range. Shape it with waveforms, a resonant filter and full ADSR, then run it through a real FX rack — vibrato, drive, chorus, delay and reverb — with five presets and a live oscilloscope. Record a take and export it to WAV or MIDI.
Ready for the full studio?
The desktop Drum Machine adds real sampled kits, your own sample import, MIDI-controller playability and deeper sound design — the pro studio version of what you're playing here.
