New patch, new track today: PJOTR This one started with source material from my man EXM. He sent over a piece he was working on and asked me to reinterpret it, so I took it into the modular and let things evolve from there. What you hear in the beginning is a short moment where his world and mine kind of phase into each other — fragments of his textures morphing before the modular machinery slowly takes over. The funny part is that his original runs at a very different tempo than my version, but somehow the transition still glues together nicely. At a certain point the grid locks in and the track settles into a steady pulse: a solid kick coming from OhmForce, with a snare/percussive FM hit from Ultra-Perc carving through the mix. Toward the end you can still hear some loose fractal remnants of his original material floating around. Then the Sovage Engineering section starts to creep in with these slightly distorted low-end textures that push the weight of the track downwards. After that the Multi-Wave appears with these strange clustered chords. I often ask him what chord the track is in. The honest answer is usually: there isn’t really one. It’s more like a constellation of notes that just happen to coexist in the same gravitational field. Somehow that still gives me enough to work with. Low-end duties are handled by a seriously growling bass from the Vhikk VCO, which really sets the mood. On top of that there’s a whole ecosystem of FM textures: metallic hits from Metalloid, more percussive FM from Ultra-Perc, and the bass harmonics interacting with all of that. The result is this dense, slightly aggressive wall of sound. For the lead I leaned on the Leibniz system from Xaoc Devices. It spits out these slightly unstable melodic fragments that occasionally drift into something that almost feels like an Arabic scale or court melody. Just sent the track back to EXM to see what he thinks. I’m pretty happy with how this one turned out. #roelfunckenmusic #eurorackmodular #idmmusic #idm #electronicmusic

Kessandrium runs at 140 BPM — fast on paper, but the 3/4 clap shifts the perception, pulling the groove slightly off-axis. It breathes inside the speed. The rhythmic core starts with Acid Rain Constellation feeding Schlappi Nibbler. Gates and CVs hit multiple inputs, generating logic-derived sub-rhythms. I flip switches live to reshape trigger density and alter rhythmic probability. Almost everything in the patch cascades from Nibbler’s rhythmic mutations — bass, chords, modulation clocks — all rhythmically entangled. Bass and harmonic layers come from an Alia Noise Engineering voice, heavily modulated. Distortion, animated filtering, and aggressive CV movement define the texture. Density is rhythm-driven, but sculpted with sample & hold across key CV paths, especially filter domains. A derivative rhythm feeds Make Noise multi-wave for chord generation, routed into Q-PAS. Low-pass stays dry and punchy. High-pass runs through Ali Trifecta — reverb and granular via the CERN preset — adding spatial fragmentation. Q-PAS receives heavy S&H modulation for shifting spectral movement. Lead voice: gritty, 8-bit, unstable. Built from the Xaoc Devices Leibniz system. V/Oct into Berlin → Jena wavetable lookup → Rostock micro-delay. Behind that, Lipsk and Erfurt intermodulate, bit-masking each other. A Schlappi clock hits Erfurt, which gates Lipsk — bits switching on/off in rhythm, producing stepped, almost sample-and-hold digital artifacts. Additional rhythmic modulation flows from Steady State Fate Ultra-Perc and Metalloid — fast, reactive, percussive CV motion everywhere. Pamela’s probability controls the master clocks feeding Constellation and Schlappi. I can thin the pattern, break it down, rebuild density, stretch tension, collapse it back into impact. Kessandrium is modulation-heavy, rhythm-derived architecture. Fast grid, warped feel. Controlled chaos with deliberate funk.
