Kenton VP-330 (after Jan 06) - Manual (Page 3)

ADDITIONAL INFORMATION
1) Receive channel setting will return you directly to playing mode, all other keys will let you stay in SET-UP mode
until you press the ENTER key (Top C).
2) The ENTER key (Top C) also performs a “reset all controllers” function (centre for pitch bender)
3) If you want to put the MIDI back to the default settings at any time, switch the synth on whilst holding the red
push button pressed - hold for a couple of seconds then release.
4) During set-up mode, the retrofit will receive on ALL MIDI channels. At all other times the retrofit is in omni-off
mode (receives on specified channel).
5) Program change is only available for the Mk2 Vocoder which has push buttons for program change – it is not
available for the Mk1 which has rocker switches.
6) To use program change on the Vocoder Mk2, programs changes 1 to 10 will operate the buttons in sequence
from left to right (e.g. #9 will select strings lower and #10 will select strings upper). As the buttons on the Vocoder
Mk2 are toggles, each time that program change is sent, that button will be toggled (change state). In order that you
can return to a known status, sending program #11 will always reset all buttons to off, you can then follow this with
the program changes for buttons you want to select. Any programs in the range 1-10 can be sent consecutively, but
#11 must be sent on its own with about ½ a second after it before sending any other programs – so at the start of a
song you could send #11 then wait ½ a second and then send any other program changes you want consecutively
to turn on the required buttons.
7) List of commands recognised - (numbers in hexadecimal)
8nH notes off 9nH notes on & velocity
0CnH Program Change (mk2 only) 0EnH pitch-bend change (down only)
0FEH active sensing
8) The Vocoder has only a 49 note keyboard. Any notes outside this range will be taken up or down in octave steps
in order to remain playable.
