7.  Patch-Sheet

The following diagrams of the module can help you
recall your own 

Patches

. They’re designed so that a

complete 19” rack of modules will fit onto an A4 sheet
of paper.

Photocopy this page, and cut out the pictures of this
and your other modules.  You can then stick them
onto another piece of paper, and create a diagram of
your own system.

Make multiple copies of your composite diagram, and
use them for remembering good patches and set-ups.

• Draw in patchleads with colored pens.
• Draw or write control settings in the little
white circles.
