Model 140

Timing Pulse Generator

The Model 140 Timing Pulse Generator is the heartbeat and nerve center of any 100 Series system. It’s far more than a simple clock.

The 140 sends out a pulse in intervals of .005 seconds to 20 seconds, and the width of the pulse can be modified by the Pulse Length knob, both of these adjustments can be controlled with CV.

The interesting portion of the 140 would be in the outputs, the two jacks on the right provide all pulse outputs, while the two on the send out alternating pulses.

This is done with an inverter circuit and a pseudo transistor logic AND gate, which monitors the high and low status of the output pulses. With alternating pulse outputs, one can interleave sequences or other triggers to initiate call and response within the patch.
