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.
