Connecting the iS35 to a MIDI accordion

There are different types of MIDI accordion and each
type requires a different configuration of the iS35.
Select one of the MIDI "Accordion" Setups to config-
ure the module properly (see page 150).

The different types of MIDI accordion
Programmable / non-programmable.
accordions can be programmable or non-programma-
ble. The programmable accordions offer the possibility
of selecting the MIDI channel assigned to each part of
the accordion, whereas the non-programmable accor-
dions feature a fixed relationship between parts and
MIDI channels.
For example, in the most common case of a non-pro-
grammable accordion, the right hand will transmit
over channel 1, the chords over channel 2 and bass
over channel 3.
Number of MIDI channels.
a minimum of three MIDI channels. The most sophisti-
cated accordions can transmit over a higher number of
channels, normally five (four plus one special part for
the arrangement change).
In the three-channel type of accordions, the right hand
transmits over channel 2, the chords over channel 2
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
recognition 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.
