Tiptop Audio Buchla 242t
Eurorack 242t Programmable Pulser: 4×12 matrix sequencer with three rows + ALL OUT and Ramp.
16 HP Eurorack module
The Buchla & Tiptop Audio Model 242t is a Eurorack reissue of a rare Buchla 200-series Programmable Pulser. An internal voltage-controlled clock drives a 4×12 LED matrix where you program three independent rows (A, B, C) of pulse patterns, plus an 'n' row that sets the loop length. Each matrix row has its own pulse output, alongside a continuous ALL OUT, two alternating outputs, and a Ramp Out for driving 292-style LPGs. External CLK In, RST In, Start In, Stop In, and Period CV give it full integration with the rest of your rack.
Features
- Eurorack reproduction of the rare Buchla 200 series Model 242 Programmable Pulser
- Internal pulse clock with rate from audio rate (~0.002 s) to 10 seconds per stage
- Period CV input with bipolar attenuverter for full clock rate modulation
- External clock input (CLK In) and reset input (RST In)
- 4×12 LED matrix programmable with two encoders and an on/off button
- Three independently programmable pulse rows (A, B, C) with three Matrix outputs
- 'n' row selects the loop length (number of consecutive active stages)
- Continuous ALL OUT direct pulse train — fires regardless of matrix
- Ramp Out for driving Buchla 292-style LPG envelopes
- Two Alter outputs for ping-pong / alternating pulse patches
- Manual Stop, Single Pulse, and Start buttons with running/stopped LEDs
- Long-press On/Off clears the whole matrix
