The QUAD SEQUENTIAL TRIGGER SOURCE is a trigger sequencer featuring four tracks of trigger positions, each with 32 steps, which can be combined to one long sequence of up to 128 steps: 4 sequences up to 32 steps, 2 sequences up to 64 steps or 1 sequence up to 128 steps. The gate positions are activated by pushing the associated button. The LED lights up. Pushing the button again deactivates the respective gate position. More than one reset position per row can be set. The active reset buttons are displayed by means of blinking LEDs. In 2 x 64 mode the gate outputs 1 and 2 respectively 3 and 4 deliver the same output, while the switch-on times of both parallel outputs may be different. This means: E. g. output 1 with a short gate time provides all active gates, while output 2 with a really long gate time provides only a few „long“ gate signals. In 1 x 128 mode the four gate outputs provide four times the same signal in parallel. This time with individual gate lengths, as desired, as well.
