Description
Draft listing upstream (info.yaml draft: true). ESP processes incoming audio through a gain stage and bandpass section, then derives envelope, gate, trigger, and pitch control signals. Main controls preamp gain, X sets lower cutoff, and Y sets upper cutoff. In switch middle, pitch updates are held unless gate is high; otherwise pitch tracks continuously. Audio Out 1 is post-gain signal and Audio Out 2 is bandpassed output.
