Future Retro XS - Manual (Page 9)

CONNECTIONS
WAVE B: This is a dual-function output of the waveform selected for Oscillator B. This is a
stereo output, although mono cables can be used here without any problem. If using a mono
cable, you can insert it all the way for the tip signal or pull it out one notch for the ring signal.
The tip of the jack provides a continuous output of Oscillator B’s selected waveform. The ring
of the jack provides the same waveform, but the amplitude of this waveform is controlled by
Envelope 1.
Either output can be connected to the input of any other device allowing the oscillator to act as
an audio or modulation source. The waveform’s output signal will have a range of –5 to +5
volts.
WAVE C: This is mono output of the waveform selected for the WAVE B control. The three
sub oscillator waveforms will have a range of 0 to +15 volts, while the ring modulator and white
noise source will have a range of –5 to +5 volts.
This output can be connected to the input of any other device allowing it to act as an audio or
modulation source.
AUDIO IN: This is a mono audio input that can be connected to any line-level external audio
source output. When a cable is plugged into this jack, you can use either the WAVE A or
WAVE C control to select EXT which will select this external audio source as its waveform.
FILTER MOD: This is the external modulation input for the filter. Connect this input to the
output of any CV or modulation source you wish to modulate the filter with.
Set the Mod Select control in the filter section to EXT if you wish to use the external source.
VEL IN: This is the external Velocity input, allowing external control voltages to override the
Velocity control generated by the internal MIDI to CV converter. Generally, you will want to
connect this input to any control voltage ranging from 0 to +10 volts.
This external signal will then control all Velocity-sensitive parameters throughout the analog
section.
GATE IN: When nothing is plugged into the Gate In jack, the envelopes in the XS will be
triggered by Note On messages received via MIDI. If you connect a positive polarity gate
output of another device to the gate in of the XS, this external gate can then be used to trigger
the envelopes in the XS. Once the external gate signal reaches +1.5 volts or higher, the
envelopes will be triggered.
GATE OUT: All MIDI note message received by the XS will be converted to a positive
polarity gate ranging from 0 to +15 volts. Connect this output to the Gate In of any other device
you wish to control with gate signals.
