21: Addsynth 2
General Description:
This voice is similar to the previous Addsynth 1. In fact, the steady-state sound of a note that has been
held down 3 or 4 seconds is absolutely identical. The only differences occur at the beginning of the sound.
The envelope generators are designed so as to bring in each harmonic of the sound separately.
Patch Information:
Identical to Addsynth 1 except for EG settings. Ops. 2-6 all have a rather slow EG Rate 1 (ranging from 7
to 23) which is combined with a Level 1 setting that is too low to be audible. This combination serves to
delay the the audible "attack" which is provided by a moderate EG Rate 2 ( ca. 50) in combination with a
maximum Level 2 setting.
Exercises:
1. Try altering the order of harmonic entrances by adjusting EG Rate 1 on Ops. 2-6. If you "get lost"
and want to get back to the original sound to try again, or before going on to Exercise 2, simply recall
a fresh copy of the voice to the Edit Buffer. (Select "Compare" under the Edit menu for Macintosh or
CARTRIDGE button followed by button "21" on DX7)
2. Experiment with the Coarse Frequency Ratios of all the operators, making sure that you set them all
to different integers.
3. Experiment with the Fine Frequency Ratios of all the operators.
