+12V (55mA) // -12V (10mA) Description- The Comper module selects and plays a sequence from a researched and extensive bank of widely used jazz, bossa nova, and pop chord rhythm patterns. It has an output with humanised bass gates, Swing/Straight 8th, and Metre.
RHYTHM (IN) METRE (OUT) - INPUTS - - CLOCK INPUT - The Comper module does not have a clock internally, so needs to be clocked externally. The three available clock resolutions (default is 24ppqn) and the tested high speed- PPQN To switch the clock to different resolutions, there is a combination to execute when the module is turned on, this is explained later on in the manual (page 9).
Comper - User Manual - RESET INPUT - When the reset input is pressed the sequence will be reset to zero at the next clock cycle. It expects a rising edge to reset. This means that to re-reset, the input will first have to be low, and it will then re-reset only once it goes back high.
The swing on the Comper is a triplet swing. Both 8th note feels are played like the following - - The top part shows a straight 8th feel, which is straight with tempo.

The chord output will output these based on the position of the rhythm knob (below). The Comper is a gate sequencer, so some gates will last for half-notes, some 8th notes, etc. - RHYTHM SELECT KNOB - The rhythm knob selects the specific preset rhythm that the Comper plays.

Comper - User Manual - TIME SIGNATURE - The time-signature switch selects between three signatures: - 4/4 (most common time signature) - 3/4 (the waltz in an example in 3/4) - 7/8 (less common, but fun to explore) TIP- It is highly recommended to explore different time signatures, even if they are not fully understood.

Comper - User Manual Bass pattern for STRAIGHT rhythms When the switch is on 4/4, the bass adopts a Bossa Nova bass pattern. The variations are making the rests (blue) into notes or turning the eighth notes (green) into rests.
- CHANGING THE CLOCK RESOLUTION - 1- Entering the PPQN menu • To enter the PPQN menu, the Comper has to be turned off. • Once off, set the rhythm knob at its lowest position, the time signature to 7/8, and finally hold both the reset and the random buttons on.
