Patch Tips #17 - Sport Detector

Using the Toppobrillo Sport Modulator as a slope detector.

One of the most interesting aspects of Mono-Poly's performance at the recent Basic Electricity night in Berlin was his use of slope detectors to generate rhythms. Feeding a pair of Ken Stone/ Elby Designs CGS762s with the outputs of his Wiard/ Malekko Noise Rings yielded unpredictable, yet in sync, patterns.

I'd previously tried the patch example in the Sport Modulator manual without much success. Inspired by the results Mono-Poly got from this configuration, I gave it another shot:

I used an LFO, reset by a clock divider to feed a Wogglebug which sampled the incoming CV at a rate set by a master clock. This CV was sent to the top section of the SM and an inverted version to the bottom. Lag for both sections was @ 2 o'clock. This setting is important as it determines the SM's reaction time and hence the accuracy or otherwise of the resulting gates. When the CV is rising, a gate is output from the top END (left channel), when it's falling from the bottom END (right).

In the examples, I toyed with the clock divider's reset, the LFO speed and also injected some chaos via the Wogglebug. As you can hear, this is a great way to generate pulse patterns on the fly.

Since flash no longer runs. . . what are you sending the two outputs from the slope detector to? Did you use a Noisering as the original patch did? Thanks!

Strange that the embed is gone; the file is still on Soundcloud. It was just two simple sounds, kick and blip: https://soundcloud.com/navs/sport-detector

I used a Wogglebug, but only as a simple S&H.
