and bass over channel 3. In the five-channel type of
accordions (usually programmable) the standard set-
ting is right hand over channels 1 and 4, chords over
channels 2, bass over channel 3, special part dedicated
to the arrangement change over channel 16 or 10.
Bass Inversion
Bass Inversion causes the lowest note sent to the chord
detection to be always detected as the chord root. The
lowest note is usually the note played with bass.
Since in some accordions bass and chords can play in
the same octave in some accordions, bass may not be
the lowest note sent to the MIDI. Therefore this note
would not be recognized as the chord root.
To solve this problem, you need to transpose an octave
below the accordion bass.
Dynamics
Not all accordions can transmit Velocity messages (e.g.
the dynamics, or intensity, notes are played with).
However, in the i40M you can select the fixed dynam-
ics value used to receive the notes sent by the accor-
dion.
The MIDI “Accordion 1” and “Accordion 2” setups
automatically select a fixed dynamics value. If the
value is not appropriate for your accordion, you can
edit the “Velocity Input” parameter in the Disk/Global
mode (see page 138).
The MIDI “Accordion” Setups
The following table shows the i40M tracks that corre-
spond to each of the 16 MIDI channels according to the
selected MIDI “Accordion” setup. It also shows the
value of the “Velocity Input” parameter.
With the MIDI programmable accordions, you can
select the MIDI channel used to send the different
parts, that is the correspondence between the i40M
parts and the accordion parts.
Accordion 1. The “Accordion 1” setup is dedicated to
those who have an accordion with three fixed channels
(with no assignable MIDI channel). With this setup
you can play Upper 1 and Upper 2 with your right
hand, Lower with the chords and the i40M bass with
the accordion bass.
