Implementing modulator

[firodj]

Hi @schellingb thanks for awesome tinySoundFont (tsf).

I am trying to enhance the tsf by implementing SF2 modulators, some of existing conversion such-as velocity to attenuation, some midi control to some modulated generators already moved to use default modulators.

I'm very excited to hear this! I (tried to) read the modulator specs a few times but it was always a very daunting endeavor. How far do you think you are, or how much do you think is left? And is there anything a general non-audio programmer like me could help with? If you think you're happy with an implementation, I'd certainly look into integrating it into mainline.
Besides modulators, a chorus and reverb effect is something we are lacking, do you have any knowledge of either implementing these effects or an implementation available under MIT license or public domain?
