Sounds like: A fast, crunchy, stuttering scatter of notes in random order.
A fast, chaotic stutter built from a randomized arpeggiator running at high speed with bit-crushed, distorted output — the arpeggiator becomes the glitch engine itself rather than a rhythmic bassline or melodic cascade.
Open this patch in the interactive PatchpadDigitone II's arpeggiator has no Random mode — MODE options are OFF/TRUE/UP/DOWN/CYCL only. The scattered, chaotic feel here comes from hand-editing each step's OFS (the real per-step semitone offset editor) to a deliberately non-monotonic sequence rather than a plain ascending/descending run, combined with fast SPEED and short N.LEN for a stuttering texture. FX page's BR/OVER/SRR pile on the lo-fi glitch layer. ALGO 1 routes operator A (and B) into carrier C, so LEV (A) and LEV (B) are set to 0 on SYN page 2 and MIX is -64 (the X output, C only): that leaves C a plain, unmodulated carrier.
SY CHIP itself has no bit or sample-rate reduction, only OVER — but Syntakt does have both on a different machine: SY BITS has real SRR and BR parameters (no arpeggiator, though), so for a crushed version put the glitch arp on one track and layer a SY BITS track, or accept overdrive alone for the grit.
Type Random genuinely randomizes note order continuously — the literal glitch-arp mechanism, no approximation needed. Rhythm 20 layers extra syncopated complexity on top, and Gate 30 (well below the default) keeps every note extremely short and stuttery. Live control: ride the panel Arp Rhythm knob and the filter Overdrive knob by hand for the chaos.
Osc 1 is BasicWaves with Morph at 50 (pure sawtooth): the Morph knob runs from a square (0) through a sawtooth (50) to a double sawtooth an octave up (100), Sym only changes the pulse width below 50, and Sub adds a sine an octave down (0 here). FX1's real Bit Crusher supplies the lo-fi crunch. Values are on MiniFreak's native 0-100 scale.
Typhon has no arpeggiator, but it has a real note sequencer (SQNCR button: 1 to 32 steps over a 6-octave range, with per-step octave, note, gate, velocity, plus probability, division and swing). Program the pattern's notes directly instead of holding a chord. Sixteen hand-set, scattered notes (for example C, G, E, C+1, F#, D, A, C, G+1, E, B, C+1, F, A, D, G): PROB 70 makes some steps drop out, and GATE is short for a stutter. The Filter and Amp ADSR and the front-panel settings shape each note.
Mode Random is a real arpeggiator direction (one of Up, Down, Up / Dn, Up & Dn, Order, Random, Chord, Phrase). Pre-FX's Lo-Fi type supplies the bitcrush texture: SAMPLING (44,100 down to 2,756 Hz) does the sample-rate crush, FILTER TYPE Thru leaves the tone unfiltered.
Novation Summit, Arturia MiniFreak, and ASM Hydrasynth Desktop all have a real, literal Random arpeggiator mode — the direct realization of this concept, and MiniFreak's Spice/Dice modifier is genuinely purpose-built for exactly this kind of glitch variation. Digitone II has no Random mode at all, so its chaos comes from hand-editing the real per-step OFS offset feature into a deliberately scattered sequence; Syntakt's SY CHIP substitute does the same with its OF2-4 offsets. Dreadbox Typhon has neither a random arp nor a macro system, so its version is a fully hand-programmed scattered step sequence.
