1k FM

What is this?

This is a 1kilobyte FM (PM) synthesizer that runs in your web browser. You can check out the commented source in uncompressed.html. This is a step further from 2048fm which has a somewhat better interface.

Features

6 Operators
ADS (Attack, Decay, Sustain) Envelope
Theoretical 34-voice polyphony (on my computer, no keyboard events fired after holding down 6 keys)
Matrix modulation indexes
Saving and loading patches
Almost 3 octave keyboard range (C to . for lower octave; Q to \ for upper octaves)

Caveats

Operators must be in order. That is, the program stops compute after it reaches an operator which have Output Volume of zero
UI drag regions wraps at border.

Example Patches

Saw Harpsichord
Drone
Lush Keys
Fifth Bass
Drunk Sine
Rhythm Machine (Best when played at Q)
