// Sparkle v0.1
// Richard Jackett 2021
// Using Paul Hamshere's SparkPedalOverride code SparkClass.ino as its basis
// There will be things in here that aren't elegant, for which I apologise. I'm not a programmer. The goal is just to get it to work.
// Bugs: too many to count, but the big ones are:
// Doesn't update parameters changed on amp, and in some other situations
// Sometimes the left/right gesture doesn't change the effect until the direction is reversed.
// Under some situations Sparkle can get out of sync with the amp. Need to look into this.
