Fig. 3: VCF cutoff control with a MIDI-synced LFO.
Set the LFO frequency so that it completes one cycle
every whole note.
During the first four 1/8th notes of the sequence, the
filter is opening; and in the last four 1/8th notes, it’s
closing.
Another example of MIDI-synchronised use of the
internal LFO is shown in Fig. 5. Two A-125 phasers
set to opposite phase are sent to two audio outputs
(Out
L
and Out
R
) to produce MIDI-synchronised spa-
tial effects.
