"I recorded this over a year ago, and there's probably numerous errors in it. Let me know and I'll add corrections as we go!

Here's a brief introduction to Meng Qi's realization of the fantastic Ciat-Lonbarde Rollz-5. It's sort-of-a drum machine which produces strange and wonderful rhythms and timbres.

Meng Qi/Ciat-Lonbarde Rollz-5 Patches

Published on Apr 17, 2019

"Here's another awesome instrument I don't use nearly enough: Meng Qi's realization of the Ciat-Lonbarde Rollz-5, which I picked up from Modular Addict

This thing is awesome: 2 sets of Rollzer (3, 4, 5, and 6), 4 AV-Dogs, 2 Ultrasound Filters (with two inputs each), and 4 gongs. The instrument is unruly and chaotic - the odd rollz can't quite produce a repeatable pattern, and some of the even ones struggle, too!

The rhythmic lengths are designated by the capacitors in each set of rollz, so there's no knob to make things faster or slower. There's only the ability to patch between them and inject and react to new rhythms and pseudo-rhythmic sonic events. As a result, even something as 'predictable' as the gong, which should just act as a tom, can produce wild timbral variation when activated by an audio-rate input. Despite such simple ingredients, loops can be created that last longer than expected, and with more variation than a normal drum machine would offer.

It's not quite a PlumButter, but it's still quite remarkable."
