MIDI Implementation

MIDI Clock

MIDI Clocks are derived from the incoming MIDI signal.

Most software sequencers provide a stream of MIDI

Clock ‘ticks’ along with the standard MIDI events. To use an external clock source of a software sequencer, you must fi rst switch the MIDI Clock control in the

Global page or Main Sequencer section. The Int Clock switch must be off to use external MIDI clocks.

There are 24 ‘ticks’ per quarter-note. Whenever you see the option to set rate or tempo by MIDI Clock, you will also get a popup list of different timing resolutions.

Cross Delay

Divisions for the Cross Delay are the same as the

LFOs, except the maximum is limited to the 2/1 setting.

However, even this is limited by the actual tempo of the

MIDI Clock, so settings for the Delay may need to be raised if the tempo is above 140 BPM.
