benjolin percussive rolls -- response to a question

"Regarding the percussive rolls, these are very easy to get. Basically, that's the Rungler in loop mode, with the rate on the oscillators (particularly B) going at a faster rate. The rungler output can be used as a clock also,and this comes in hand when the rates on the oscillators are up higher, because while both the pulse outs and the rungler run at -5/+5, peak to peak, because of the length and of the rungler Step patterns the positive edge comes at a much slow rate than that of the pulse outputs. In this way the rungler can be used to obtain percussive roll type effects from the benjolin outputs as well as with other modules.

With regard to clocking the rolls, it depends on what you mean, you can control where they drop initially, by using a precision clocked module such as the 4MS RCD or SCD modules, but you can't always control exactly where the rolling effect will end, this is because depending on the settings of the module, the loop function may also excite the rungler after the loop is complete. This being said, as long as you are using a precision cv to clock the hold pattern you can maintain a substantive amount of control over the behavior of the rungler as well as the other outputs. In addition, if you run precision triggers, gates or envelopes into the oscillator CVs and the filter cutoff this creates even more control over the chaotic functions of the benjolin. This is demonstrated in my video "in response to a question" where the trigger and gate out puts of the 4MS modules are being used as CVs for both oscillators and the filter, and later in the video to hold the rungler pattern as well. Keep in mind also that the chaotic behavior of the benjolin can be greatly limited (even eliminated) by using the Rungler attenuator knobs on the right of the panel. When you turn these all the way CCW, this breaks the interfence pattern that animates the aleatoric patterns that the core circuitry produces."
