Synth by Brain Control

Free Product
Tunefish v4 was developed as a smaller replacement of Tunefish v3 with roughly the same power. It was developed for our intro "Turtles all the way down" which forced us to rethink how to most effectively produce music in very tight machine code. This is how we've come up with creating a very small additive/wavetable synthesizer that can produce a broad range of different sounds without many parameters or machinecode.
The synth is free and comes without any warranties. 


  • Improved UI compared to TF3 which will visualize all modulations
  • 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
