External Frequency Control Input
Allows to control the oscillator pitch by an external control voltage (CV) or an external
resistor. By connecting a jack to this input, the internal envelope follower device will be
shut off and instead the fed in control voltage is adjusted by knob
,
regulating the
amount of pitch control by the CV.
The modulation CV also can be inverted by switch . Normally, a higher voltage will cause
an increasing pitch and vice versa. With in lower postion ("Inversion") a higher voltage
will cause a decreasing pitch and vice versa.
Further, a +5V voltage (via 10kΩ resistor) is provided on , available on the middle
connector of a 3pole jack plugged in . Thus may be useful, for example, in combination
with a sensor or a pedal. In the latter case, a common passive foot pedal with 3pole jack
should work.
In combination with analog synthesizer equipment (e.g. sequencers, monophone
keyboards), it is possible to calibrate the XR1-E on 1V/Oct. by adjusting knob .
To calibrate on 1V/Oct for tracking with other instruments, connect the
external CV source to and set the pointer of the "Envelope/
ext.Modulation" controller to nearby "
7 " on the scale. This is a good base.
Then adjust by listening with different CV values until the pitch matches
with the pitch of your instrument.
