If you have already created a pattern including synth notes, you can change the keynote to
transpose the pattern, even while the pattern is playing. You can also change the scale itself
for an existing pattern. In this case, some notes in the pattern as it was created may not exist
in the new scale. In such a case, Circuit makes an intelligent decision as to which note to play
instead, which will normally be either one semitone above or below the original note.
Selecting Patches
Each of the two synth tracks in your Circuit can use any one of 64 pre-loaded Patches
(Presets). These Patches have been developed specically for Circuit, and are listed on the
Patch Sheet packed with the unit.
To change the Patch for Synth 1 or 2, hold down Shift
19
and press Synth 1 or Synth 2
5
as
appropriate. This opens the Patch View Page 1 in the case of Synth 1 and Patch View Page 2 in
the case of Synth 2. Synth 1 and Oct J (or Synth 2 and Oct K) will illuminate white and each
of the pads in the grid represents 32 synth Patches: Patches 1 to 32 for Synth 1 and Patches 33
to 64 for Synth 2. To view the other page in the case of either synth, press the non-illuminated
Octave button.
The pad corresponding to the currently selected Patch will be illuminated white and the others
will be purple (Synth 1) or green (Synth 2). Patch 1 is the default Patch for Synth 1 and Patch 33
is the default Patch for Synth 2.
To select a different Patch, press its pad. The synth (1 or 2) will now adopt the sound dened by
the new Patch. You can change Patch while a pattern is running, though the transition may not
be absolutely smooth, depending on the point in the pattern when the pad is pressed. Changing
the Patch of a saved pattern does not alter the Patch that was originally saved with the pattern,
unless the session is re-saved.
Patch Preview
You can hear what the Patches sound like while in Patch View by using Circuit’s Patch Preview
feature. Patch Preview will take into account the current Scale and Root Note setting when
playing a Patch.
If you hold down Shift
19
while pressing a pad in Patch View, Preview is disabled; this may be
desirable in live performance when you know which patch you’re using and don’t need to hear it
on selection.
Patch Preview is disabled when Circuit is in Record Mode.
External Patch Select
Synth Patches may also be recalled from an external MIDI controller by sending Circuit MIDI
Program Change (PGM) messages on MIDI Channel 1 (Synth 1) or Channel 2 (Synth 2). Circuit
must be congured to receive Program Change messages: this is the default setting, but see
“MIDI I/O” on page 67 for full information.
The separate downloadable document Circuit Programmer’s Reference Guide contains full
details.
