Different envelopes with each note played
With the patch in Fig. 4, every time a new note is
played, a different envelope will control the VCF.
Each gate signal from the keyboard moves the A-161
another step forward, and so triggers the next enve-
lope. The envelopes obviously need to have different
settings for the effect to be noticeable.
The outputs from the envelopes are patched into an
A-138a (linear) mixer. At its output, the envelope is
available to be patched into the CV input of, most
commonly, a VCF or VCA.
After four steps, output % on the A-161 resets the
A-160, so that the first envelope is triggered again.
However many (n) envelopes you use (up to a maxi-
mum of seven), you must patch the next output on the
A-161 (n+1) to the reset input on the A-160. With
more than four envelopes, two A-138a mixers will be
needed.
