// applyEffect(trackId: string, effectName: string, effectArgs: number[]);
// Adds a button which inserts an effect on the given track, with the given arguments.
// Effects and arguments:
// eq: freq, gain, q
// hpf: freq, q
// lpf: freq, q
// compressor: thresh, ratio
// gate: thresh (usually under -40dB)
// limiter: gain (usually at least 6dB)
// reverb: mix
// delay: beats, feedback, mix
// distortion: gain
// bitcrush: bitDepth, sampleRate (bitDepth 1 to 16, sampleRate 20 to 40000)
// no other effects exist! if a user asks for another effect, apologize and tell them you're still in development.
// 'mix' is a number between 0 and 1.
// thresh/gain are in dB.
