F.K. RAEITHEL — Aber Was Ändert Das? / Quantitative Unbestimmbarkeit I–iv (tape)

In December 2025, I performed alongside Asmus Tietchens and Jetzmann at the final Hörbar Ausklang Festival. This cassette was produced for that occasion. It contains preliminary studies for my live modular synthesiser performance. The tape wasn't sold on the night, and its release ended up being postponed until now. At one point I had almost forgotten that I had even produced it. Now it's finally here—but what does that change? Side A features a 24-minute piece titled Aber Was Ändert Das? (What Does That Change?) Aber Was ändert Das? – Two oscillators coupled via a comparator and routed through a filter bank form the foundation of this piece. Eight filters within the bank are modulated by a synchronised octal triangle wave. Over time, the modulation gradually unfolds like an abanico (fan), shifting into different patterns. The impulses slowly dissolve into noise. A looping voice tape is added to the texture, and the piece concludes with a melody of comb-filtered sine tones. Side B presents several variations and adjustments of a self-generative patch. Quantitative Unbestimmbarkeit I-V (Quantitative Indeterminacy I–IV) – At the core of these pieces is a source of uncertainty and three function generators programmed in mutual feedback. The tonal material is derived from a wave-folded sine wave, a noise source, and a pinged state-variable filter. This type of self-generative patch is commonly known as a Krell patch. The edition is limited to 50 copies. Release day will be the August 7th, 2026. The title Miszellen Band is derived from the term Miszelle (plural: Miszellen), which refers to a short informative text or brief scholarly essay, often published in academic journals or collected volumes under a "Miscellanea" section. The word originates from the Latin miscella, meaning "mixed things". Such texts typically explore highly specific subjects without the scope or depth of a full-length study. They often consist of etymological notes, addenda to previously published work, concise discussions, or small discoveries from archives.
