Triggered output, and the Control voltage outputs. 10 (White & Orange Control Knobs) are the voltage output for each of the channels, each of the 10 channels has an on/off switch. The RED LED's are the pilot lamps for the channels, they will scan from Top left down, then right up. The Red Control knob (Freq) is for the speed of the scanning. The power input is on the back of the unit and instuctions will be sent with this. Fully grounded and IC's are socketed. I have tested this on my Synth and works great. Switchcraft parts (Instructions will be sent when shipped)

Each sequencer A & B have twin CV outputs, they are complete isolated from one another, same goes for the A/Trig and the B/Trig. You can use one or both, it does not matter how you use them. Each sequencer will operate freely from one another.
This has 2 seperate 10 channel sequencers in one unit. They both will work independant from one another. Each sequencer A or B will work off thier own "Freq" control.

Each A or B has Clock Input Jacks for External Timing control. When a signal is applied at that input it will turn off the internal clocks. The Freq LED will continue to flash but it will not have any control over the sequencing rate, that will be controled by the external input clock. This works for both A and B Clock Inputs.
You can sync them together either A sync to B or B to A, there is a center control that will work as follows:
Norm: CENTER (Yellow Control Knob) is Normal operation mode
AxB: Sequencer A (left side) A scans 1 thur 4 then will send pulse to Seq B.
BxA: Sequencer B (right side) B scans 1 thur 4 and will send pulse to Seq A.
A+B: Sequencer A will scan both A+B
BsynA: Sequencer B will sync B to A, Freq B will control both B and A
AsynB: Sequencer A will sync A to B, Freq A will control both A and B
The Unit measures 6 1/2 x 13 1/2 x 3 1/2 inches. Un-finshed wood cabinet."
