Tunefish synth

Tunefish is a very tiny virtual analog synthesizer. It is developed to fit into about 10kb of compressed machine code while still producing an audio quality that can compete with commercial synthesizers.

Uses an additive synthesis based wavetable generator
The Noise generator can produce any frequency of noise with any bandwidth
Lowpass, Highpass, Bandpass and an improved Notch filter are available
2 ADSRs and 2 LFOs that can be linked to pretty much any important knob using a modulation matrix
Supported effects are Flanger, Chorus, Distortion, Delay, Reverb, EQ and Formant
The effects stack allows for any permutation of up to 10 effects
