A Polyrhythm (Rock Artist Reverb)

This one - the eighth in the series, uses two randomish sources - the stoermelder Hive hexagonal sequencer from Benjamin Dill and Anthony Lexander Matos and three iggy.labs More Ideas - an "elementary cellular automata" - by Isabel Kapriskie, connected in a feedback loop and also controlled by the Hive.  These control two sets of oscillators.  One, a set of two FM pairs (using Antonio Tuzzi's NYSTHI TZOP oscillators) which are processed through the NYSTHI Convolvzilla convolution reverb (the impulse response in the reverb is classic jazz DJ (and virtuoso jazz singer) DeeDee Bridgewater saying "rock artist"); and the other, two Audible Instruments Resonators, making physically modeled percussion sounds, processed by the NYSTHI Plateverb.  The tuning is a 7-note Recurrence Relation (Additive Sequence) scale based on Erv Wilson's work (made with Marcus Hobbs' Wilsonic app), and the two polyrhythmic Improptu Clocked modules (by Marc Boule) are driven by the Seriously Slow LFO from Frozen Wasteland (Eric Sterling).  This LFO makes a single ascending ramp, five minutes long, which drives the piece in a continuous accelerando for its duration.  This may all sound like techno-mumbo-jumbo to the uninitiated, but what it produces is a (to my ears anyway) very nice complex accelerating polyrhythm with enough timbral interest to keep my ears puzzling things out as well.  A kind of audible maze for one's ears, and consciousness, to happily wander within.  The long cast-list of module developers shows a bit of the incredible community collective effort that is involved in the VCV Rack project.
