/* Pro 3 Morph Controller Generator
 *
 * Usage:
 * 
 * ./morph-controller wavetable-number name level1 ... level16 > sysex-file.syx
 * 
 * wavetable-number is a number between 33 and 64
 * if wavetable-number is 0, pro3-lfo outputs raw PCM instead of sysex
 * name is a string of up to eight characters
 * 16 levels between -32768 and 32767 must be provided
 *
