POWER-UP SEQUENCES FOR ACCESS TO SOME SPECIAL FUNCTIONS
The Hei-di MIDI controller combined with the built-in sound card is a user friendly
system that allows access to more than a hundred orchestral sounds without the need
to carry an external MIDI module. The MIDI accordion is ready for use by simply
connecting all cables and powering up the system.
Some global parameters can be accessed and changed during initial powering up of the
system as described below.
1. Assignment of the transmission midi channels
Press and hold button number 0 (the first one) from the
treble A
section while powering
up the system. After initialization the grill MIDI controller will have one LED on in each
section. This represents the current transmission MIDI channel for that section. Treble
A and Treble B sections can be assigned to channels 1-12. Bass and Chord sections
can be assigned to channels 1-6.
The default MIDI channels are:
-
Treble A = 4
(or 12 on Ver.2)
-
Treble B = 1
(or 11 on Ver.2)
-
Chord = 2 (the LED for the second button in the chords section is ON)
-
Bass = 3 (the LED for the third button in the bass section is ON)
If you have MIDI controller Version 2 (Treble A set to channel 12 and Treble B set to
channel 11) and would like to use the accordion with an external MIDI module, change
the Treble-B transmission channel from 11 to 1 by pressing the first button from Tr-B
group. Press EDIT to exit.
If you have Ver. 1 MIDI controller (Treble A assigned to channel 4 and Treble B to
channel 1), please read below how to use the instrument with external MIDI module.
Before making any changes to the default MIDI channels, please record the current
settings. The default channels match the default receiving channels of all MIDI
expanders.
We don’t recommend changing the transmission channels for Bass and
Chord sections since then you will not be able to access the internal sound card. If
you still need to match these channels with your external MIDI module, please
consider making the change on the external MIDI module receiving side.
2. General reset of the instrument
– restores the factory state of all parameters. Any
custom user presets that you have saved will be lost.
Press and hold button number 1 (the second one) from the
treble A
section while
powering up the system.
3. Reverberation and Chorus effects.
Press and hold button number 2 (the third one) from the
treble A
section while
powering up the system to disable the effect. Repeat the procedure to enable them.
4. Bellows dynamics.
Press and hold button number 3 (the fourth one) from the
treble A
section while
powering up the system to disable the bellows dynamics. To enable, repeat the power-
up sequence. The bellows dynamics could be disabled/enabled in real time for any
channel from the BELLOW controls on the grill controller
