Clock settings
When Clock Rx is OFF, the clock is in internal mode and Circuit Tracks’ BPM is defined only by the
internal tempo clock. Any external clock will be ignored. When Clock Rx is ON, Circuit Tracks is in
AUTO mode and the BPM will be set by an externally applied MIDI clock at either the MIDI In or the
USB ports if a valid one is applied; if this is not the case, Circuit Tracks will automatically switch to its
internal clock.
If Clock Tx is ON, Circuit Tracks is the clock master and its clock – whatever the source - will be
available as MIDI Clock at the rear panel USB and MIDI Out connectors. Setting Clock Tx to OFF will
result in no clock data being transmitted.
See also “External clock” on page 86.
Analogue clock rates
Circuit Tracks outputs a continuous analogue clock from the rear panel Sync Out connector
2
at an
amplitude of 5 V. The frequency of this clock is related to the tempo clock (internal or external). The
output clock rate is set with the first five buttons on the third row of the grid (Pad Nos. 17-21). You
can select the rate to be 1, 2, 4, 8 or 24 ppqn (pulse per quarter note) by pressing the appropriate
pad. The default value is 2 ppqn. The following table summarises the settings:
Pad Analogue clock rate
17 1 ppqn
18 2 ppqn
19 4 ppqn
20 8 ppqn
21 24 ppqn
Note that Swing (if set to something other than 50%) is not applied to the analogue clock output.
