Repeating notes played on keyboard
In the patch in Fig. 2 each note played on the keyboard
produces two sounds: the first when the key is pres-
sed, and the second when it’s released.
To achieve this, output $ (+/-) on the A-165 is used.
The ADSR attack time needs to be very short.

Repeating notes with ping-pong echo
A modification of the previous patch is shown in Fig. 3.
In this case, the sound is repeated when the key is
released, but this time from a different output: at the
original key-press, the sound goes to one VCA (Out
L
),
and on release goes to the other VCA (Out
R
).

The patch sounds particularly good if the triggering is
provided by a sequencer (like the MAQ 16/3) instead
of a keyboard.
