Synth 1, (Synth 1) Sidechain and Synth 2 are lit; selecting each of these generates a pattern
of illuminated pads; the pattern represents the version numbers of the three rmware elements
in binary form. You may need to describe these patterns to Novation’s Technical Support Team
in the event of a problem.
Bootloader Mode is most easily exited by simply pressing the Play button. Circuit will then
reboot into the normal operating state.
MIDI I/O
Circuit is able to send and receive MIDI data both via the USB port
3
and the dedicated MIDI
IN and MIDI OUT sockets
2
. Use the 3.5 mm TRS jack-to-5-pin DIN breakout cables supplied
to use standard MIDI cables to connect the latter to other MIDI equipment.
When it is shipped from the factory, both MIDI Rx and MIDI Tx are ON.
To enable/disable MIDI transmission (Tx) and/or reception (Rx), Circuit must be placed in a
special Setup View. This is accessed by holding down Shift
19
while powering Circuit on.
(Remember to save any unsaved work before powering Circuit off!)
The display will look like this:
MIDI RX
On/Off
MIDI TX
On/Off
AUTO Sync
On
Internal
Clock
On
The rst two pads in the bottom row control MIDI Rx and MIDI Tx respectively. A red
illumination means that Tx or Rx is OFF; a green illumination that Tx or Rx is ON.
Note that the MIDI Tx/Rx settings have no effect on how Circuit uses MIDI clock. Clock settings
are described on the following page.
