Using the Octatrack as a multiple clock source/divider/multiplier
“Feed up to four tracks with a simple square wave or short audio impulse. Connect the four outputs to whatever a clock needs in your modular system. Adjust levels/ duration of the audio impulses to fit for the clock inputs of your modules.
“Set steps on each sequencer of the four tracks: with each step set on a 16step sequence, your module will run at the same speed as the Octatrack. With setting 8 steps, 4, 2 or 1 step you can divide the clock by 2, 4, 8, 16. Set general tempo within the Tempo screen and the Level knob (or Up and Down arrow keys). Or use the Tempo Multiplier (in the Pattern Scale Setup), offering seven possible settings: 1/8X, 1/4X, 1/2X, 3/4X, 1X, 3/2X and 2X. This should work with any sampler.
