24: Addsynth 5
General Description:
This voice, too, is derived from Addsynth 1 and shares an identical steady-state sound with it. It also
shares with Addsynth 4 the concept of harmonics fading in one by one over a period of time. The differences
this time are that the harmonics enter in opposite order, from high to low, and take longer to enter. This is
of course similar to opening up a high-pass filter.
Patch Information:
Identical to Addsynth 1, except EG Rate 1 settings for Ops. 1-6 ascend from 15 to 70 as the harmonic ratio
ascends by whole integers.
Exercises:
1. Assign the same Rate Scaling value to each operator so that time-delays for entrances of the
harmonics vary according to the highness or lowness of the key depressed. Try several different
"across-the-board" values.
2. Try adjusting the EG for Ops. 2-6 to give the illusion of sweeping the center-frequency of a band-pass
filter from high to low. Hint: Put all Level 3 and Level 4 settings for Ops. 2-6 to "0" then adjust the
Rate 2 settings so they read something like 30, 35, 40, 45, 50.
