Sequencer
Panning controlled by voltages put out by a se-
quencer such as the A-155.
In the patch in fig. 5, the control voltages are
produced by the lower row of the A-155, so that
as the sequence runs, each note is positioned
at a different place in the stereo soundstage.
(Lessening the abrupt changes between volta-
ges can be achieved by using Post Out 2 on the
A-155.)

MIDI Interface
By patching in a MIDI interface (such as the A-
190 or A-191) you can use virtually any MIDI
Controller message to control panning (for in-
stance the mixing two signals using Aftertouch).
You can also use the pitch information genera-
ted by the MIDI interface to control any aspect
you want - for instance voltage-controlled pan-
ning using pitch data, perhaps making lower no-
tes appear more on the left of the soundstage,
and higher notes on the right.
