2nd part of demonstration. Three jacks was applied on this drum machine, Trigger IN, Trigger Out and Start / Stop Out. On this demo, the Trigger IN feature is shown. When a 1/4" jack is connected on the Trigger input, the sequence stops, and remain in "waiting" mode for an external trigger. On this case the trigger is provided from a gate out of a Roland MPU-101 midi converter, then a midi software running on a PC (not shown) controls the tempo of the drum machine, beyond its own internal clock capabilities. On high speeds the refresh of the webcam can't permit to see the MPU-101 gate LED flashing synchronized with the EKO sequence, but in very low tempo is easily noticeable.
