below). If you have entered the learn mode by mistake you can leave it by pressing the learn
button again. The learn mode will also be terminated if one of the MIDI events in the table
below is received.
While the MCV4 is in learn mode the following parameters can be adjusted via incoming
MIDI messages:

The factory setting of all parameters is described on page 6.
Whenever the MCV4 receives one of the MIDI messages listed in the table above the
parameter in question is changed and the MCV4 returnes to the normal play mode, i.e. the
LED stops flashing. Pay attention that not unintentional MIDI messages appear while beeing
in the learn mode (e.g. from a sequencer) as you change the settings of the MCV4 with such
MIDI messages. All parameter changes made while beeing in the learn mode are stored non
volatile in the MCV4 parameter memory. When the MCV4 is turned on next time the
parameter settings are taken from this memory.
Remarks
(1) MIDI channel/reference for CV1=0V
In case of an incoming note event in the learn mode the note number and the channel of the
event are taken over as the new REFERENCE NOTE and MIDI CHANNEL of the MCV4.
The reference note is the MIDI note number that belongs to 0V CV1 output. In practice you
simply enter the learn mode and press the key on your MIDI keyboard that should belong to
0V CV1. MIDI note events below the reference note or more than 5 octaves above the
reference note are ignored as the CV1 voltage range of the MCV4 is 0...+5V. The factory
default settings of reference note and MIDI channel are 36 (C) and 1.
(2)...(6)
For the setting of these parameters MIDI Program Change messages coming from your
MIDI device are used. Normally you will have to press the program change keys on your
MIDI keyboard or MIDI synthesizer while beeing in the learn mode. Pay attention that some
manufacturers count the MIDI program change numbers from 0....127 rather than 1...128 as
usual and defined in the MIDI standard. If the lowest program change number you can send
with your MIDI device is 0 (zero) you have to subtract 1 from the program change numbers in
