Berlin School 960 Sequencer - Step Inputs/Outputs

video upload by O.Z. Hall

"This demo shows how to use the step inputs and outputs to control which steps in the sequence are played. This is a classic Tangerine Dream technique to break the monotony of playing the same 8 steps repeatedly.
I'm using the Swiss Daisy DSP as a virtual analog voice with delay. The controls I'm adjusting are the wet/dry mix, the envelop to VCF amount and the VCF cutooff frequency.
The simplest example of using the step in/out would be to take the step out from step 5 and connect it to the step in on step 1. This would result in the first four steps being played. (i.e. a reset to change the sequence length from 8 to 4 steps).
In order to quickly repatch to select the step out and step in, I have used a dual 4:1 selector switch, the Frequency Central 'Where" module:

(no, I'm not paid for this link).
The top switch selects the beginning step; the bottom the ending step.
If the ending step number is BEFORE the beginning step number, the sequence skips the "ending" note and jumps (forward) to the "beginning" note.
One other wrinkle, the "step out" stays high for the entire step duration. I have turned this 100% "gate" into a trigger by running it through an A/D envelope.
One other note, I'm using row three to adjust volumes at each step."
