Tiptop Audio Buchla 264t
Quad Sample-and-Hold + Polyphonic Adaptor with built-in ART Quantizer for Tiptop Buchla 259t.
18 HP Eurorack module
The Buchla & Tiptop Audio Model 264t is a quad sample-and-hold module enriched with a built-in ART quantizer and a polyphonic adaptor. Each of four channels has its own CV In, CV Out, Pulse In, Pulse Out, and a Track-vs-Sample mode switch. The four CV outputs are fed in parallel through a quad ART quantizer (Scale: ch/m/M; 12-position Key) and emerge as ART outputs sized for ART-equipped oscillators like the 259t Complex Oscillator. The polyphonic adaptor section round-robins pulses across 1–4 voices for instant duo-, trio-, or quad-voice patches.
