New Percussa SSP Arpeggiator Module with Clock Multiplier


arpeggiator module demo #1 - percussa ssp Published on Sep 30, 2018 PERCUSSA

"2 arpeggiators driven by the step sequencer module on the ssp, each arpeggiator sending a pitch signal to a different sine wave oscillator. The 2nd arpeggiator is choosing randomly between step increase/decrease. Learn more about the ssp at www.percussa.com"

"New Arpeggiator Module with Clock Multiplier (kickstarter stretch goal)
You can grab the preset to learn how to use the arpeggiator here -

The module has the following inputs:

Signal input - feed a signal into this input from which the arpeggio will start (e.g. a pitch signal such as the L1 output from the step sequencer)
Clock input - feed a clock signal into this input, which will be either multiplied or divided internally by the arpeggiator’s internal clock divider/multiplier (e.g. the clock output of the step sequencer)
Reset gate input - feed a gate signal into this input to “reset” the arpeggiator to the level present at the signal input (e.g. the G1 output of a step sequencer)
The module has the following outputs:

Out - the output of the arpeggiator
Gate - a gate signal going high for each arpeggio “step”
Clock Multiplier Out - the divided/multiplied clock created using the clock input, internally in the arpeggiator.
As you can see, you can use the arpeggiator module also simply as a clock multiplier. Just feed it a clock and grab the multiplied/divided output from the arpeggiator’s clock multiplication output.

The parameters of the arpeggiator:

Step - this is the value that the arpeggiator adds to the input signal each time it advances a “step”. Can be both positive for a climbing arpeggio or negative for a falling arpeggio. The output of the arpeggiator will wrap around, which means that if the arpeggio is long enough to “clip” the signal it will wrap around and show up at the bottom of the signal.
Length - the number of “steps” in the arpeggio
Ratio - clock division / multiplication factor
Rand - will randomly add/subtract the step value on each arpeggio “step” so you get a randomly climbing/falling arpeggio."
