SawCutter 2.0

Envelope Editor

Overview

Adjust the three envelopes for the selected instrument.  The red envelope controls the volume or amplitude of the note.  The green controls the pitch and the blue controls the frequency cutoff.  When using hand drawn waveforms the cutoff will vary with the frequency of the note.  When using MIDI commands to trigger notes the note played will have a minimum length that is specified by the "end" waveform position.  The maximum length of the envelope is four note steps.  If the note is longer than 4 note steps the sustain portion of the envelope will be looped.

The pitch envelope changes scale based on whether the waveform currently being used is hand drawn or and imported wave.  If the waveform is hand drawn the pitch is scaled non-linearly between plus and minus an octave.  If the waveform is an imported wave, then the pitch is scaled linearly between 3x speed and reverse 1x speed (i.e. if the pitch envelope is set to zero, the the waveform is played backwards at regular speed.)
