CV GATE OUTPUT EXPANSION
Engine can be expanded with an optional CV/Gate output expansion board. The CV/
Gate board adds eight pairs of CV/Gate output, which can be used to control modular
synthesizers, etc.
The CV and Gate outputs use 1/8" (3.5mm) tip-ring (mono) jacks. Each output is
buffered for circuit protection.
The range for the CV outputs is (about) -3V DC to +7V DC.
The GATE outputs are 0 to +10V DC.
The CV/Gate output expansion has a built in hardware slide circuit that is automatically
engaged when a slide is programmed into a pattern. This gives a smooth analog slide on
the CV output. The slide time is preset to about 70mS, the same as the classic 303 slide.
INSTALLING THE CV EXPANSION BOARD
To install the CV expansion, first power off and unplug Engine. Next you will need to
remove the two hex screws holding the blanking panel in place over the expansion port.
After removing the blanking panel, you will see a 10 pin connection header inside Engine,
coming down from the mainboard.
