Adjusting the Prophet-5's CV Input Scaling:

The Prophet-5 is calibrated at the factory so that 0v received at the rear-
panel jack will produce the same pitch as the lowest C note on the
cv in
instrument's keyboard, and 5v will produce the highest C note. Depend-
ing on the device you wish to use to control one voice of the Prophet-5
from the CV Input, you may need to make slight adjustments to these
voltage points in order for your controlling device to cause the Prophet-5
to produce the correct pitch. Some devices may not produce perfect Volt/
Oct voltage scaling, but the Prophet-5 can accommodate.
Adjusting CV Input scaling:
1. Connect the CV Out of the controlling device to the Prophet-5's rear-
panel
