The Programmable Pulser Model 242t from Tiptop is a Eurorack version of the classic pin-matrix equipped gate generator. Updated for Eurorack, the pin-matrix has been replaced with a 4x12 matrix of LEDs which you can scroll through using the two knobs below. This will let you address each channel individually to tell it to fire off a signal with a 4th n channel letting you change the overall length of the sequence. Use this as the main heart of your patch, or as a way to further manipulate pulses with the Clock In and Reset inputs. The All out and Ramp generator, however, remain tied to the internal clock, which can create some interesting rhythmic variations. Period controls the internal clock and can be CV controlled for organic movement, and an Alter section sends out alternating pulses. Whether you have experience with the classic module, are looking to complete your Buchla Eurorack system, or just need a flexible mutli-channel programmable clock, the Model 242t is here to keep your finger on the pulse.

This video showcases how the 242t interacts with other 200t modules, driving a unique patch that triggers and controls a feedback loop system.

Patch Overview of "Triggering Feedback Loops":
The 242t sends pulses to a network of modules to generate sequences and modulations:
242t: Sends pulses to the 245t, 266t, and 281t for creating CV sequences and dynamic modulations.
259t: Serves as the primary VCO, delivering the audio foundation.
292t: Shapes the audio signal from the 259t.
Feedback System Details:
Tiptop ZDSP: Processes the 259t’s audio output (filtered by the 292t). Its outputs feed the 296t and 285t, which send their processed signals back into the ZDSP’s feedback inputs, creating a controlled loop.
296t: Operates also as an envelope follower, analyzing the ZDSP’s output and generating CV. The CV is sent to MISO, where it is inverted and routed back to modulate the ZDSP’s feedback inputs, acting as a limiter to prevent saturation.
