MIDI Control Codes
The XONE VF-1 has a standard set of MIDI control assignments. This is always used for MIDI
output and input and cannot be disabled. Three additional MIDI In modes can be enabled to
allow for advanced applications using additional MIDI messages.
Standard MIDI Assignments
These are used for both MIDI Input and output. To control the
filter using MIDI make sure the VF-1 rear panel Local OFF switch
is pressed in. For all parameters, except VCF Frequency, MIDI
outputs the current status of the filter regardless of the setting of
the Local OFF switch or whether the filter was changed using the
front panel switches or MIDI input. For the VCF Frequency, MIDI
outputs the current position of the front-panel control, not the
actual filter cut-off frequency. This means that the VCF Frequency
MIDI output follows the front panel control whilst the VF-1 filter
follows the MIDI input.
