Arp Odyssey LFO free-run
The LFO on the Odyssey is reset each time a key is
pressed. (Or triggered externally by a Midi/CV converter.)
This simple modification adds a switch which,
when open, allows the LFO to run free.
Cut the track between the resistors and transistor
as shown on drawing.
Each side of the cut is attached to the switch
by a wire as shown.
To avoid any drilling in the cabinet, the switch
can be mounted in place of one of the High/Low output sockets.
I suggest to move the output wire from the high
to the low output jack, remove the two resistors and relabel the low output
The original high out phono socket can then be
removed and replaced by a small toggle switch.
