Appendix D: Modulation Sources and Destinations
Modulation Sources
Note played Log The note being played with exponential
response. The modulation value follows the
frequency of the played note (bipolar).
Note played Lin The note being played with a linear response.
The modulation value follows the note number
(bipolar).
Velocity The MIDI note-on velocity information. The harder the key is hit, the
higher the modulation value (unipolar).
Aftertouch MIDI pressure / aftertouch information. Alpha responds o both
polyphone and monophone aftertouch (unipolar)
Pitch Wheel The value of the pitch-Wheel is takes as modulation source, maybe it
makes sense to reduce the Pitch Wheel range to 0 when using the
Pitch Wheel as modulation source. The Pitch Wheel is bipolar
Modulation Wheel The MIDI modulation wheel (MIDI CC 1) (unipolar )
Amp Envelope The envelope of the Main Amplitude. This envelopes control the
overall Volume, however if it makes sense within the sound to do so,
the envelope can be used as a modulation source (unipolar).
Filter Envelope The envelope of the Filters Cutoff. This envelopes control the Filter
cutoff frequency, however if it makes sense within the sound to do so,
the envelope can be used as a modulation source (unipolar).
LFO 1 to 3 LFO 1 to 3 (bipolar).
Random There are also two random sources: Random Unipolar and Random
Bipolar. This random values stays constant during the note being
played but changes upon each trigger of a new note. So its different
for each note.
To have a modulation source which is random and changes while the
notes is played, use a LFO with the Noise waveform.
Alternate The Alternate modulation source changes between values of 1 and
-1 for each note. (bipolar).
Constant A constant value of 1, sometimes useful to apply static modulation,
e.g. of the oscillator symmetry. (unipolar)
