Simple 4-OP 8-Algo FM Synth
surFMan is a simple FM synthesizer with 4 Operators and 8 Algorithms.
There is also a modulation section including 4 LFOs and 4 Envelope Generators as sources.
Finally there is a Tape-style Echo effect with saturation and flutter.
Where surFMan loses in bells & whistles it gains in simple UI and ease of programming.
