Midi Accordions - KETRON SD1 User Manual

MIDI Accordions

The SD1 can be managed by an Accordion connected via MIDI, thanks to the fact that the attribution of the MIDI channels to the single parts of
the keyboard, the bass transposition, the velocity and also the use of the bass timbres can be controlled. The controls directly depend on the
MIDI implementation of the Accordion therefore, for very simple MIDI accordions some of the functions described hereafter will not be avail-
able.
CONNECTING A MIDI ACCORDION
The MIDI Out Output of the MIDI Accordion is to be connected using a MIDI cable to the MIDI 2 In input (Keyboard) of the SD1 and then enable
the Accordion mode on the SD1.
ENABLING THE ACCORDION AND ITS PARAMETERS
The parameters for the MIDI Accordion are accessed, from the main page of the display, by pressing F3 Utility and, from the first page of the
Utility menu, by pressing F6 Accord. A new page of dedicated parameters opens. When the Accordion is connected, the Accordion mode is
enabled by pressing F10, which from disabled (Inactive) becomes enabled (Active). To disable the Accordion mode press the F10 push button
again. The Accordion mode calls up a number of MIDI settings that can however be modified as desired.
The parameters available in the Utility Accordion menu are the following:
F1 Chord Mode: This is used to select two different methods for acknowledging the chords. International is the most widely used sys-
tem, Belgique is to be used only to acknowledge Belgian chords. Press function push button F1 to switch from one sys-
tem to the other.
F2 Left Velo: This selects the velocity curve for the notes played manually using the chords of the Accordion. By pressing the F2
function push button repeatedly you can select the response curve. In the case of Fixed curve you can enter the fixed
velocity value applied to the notes played using the VALUE +/- push button.
F3 Right Vel: The same as for F2 Left Velo but dedicated to the notes played with the right hand, namely the lead.
F4 Left Drum: When set as On, it is used to play two percussion timbres of the Drum section of the SD1 with the bass timbres of the
Accordion and another two timbres with the Accordion chords. The two timbres with relative velocity values can be
selected for chords and bass. Using the CURSOR +/- push buttons, go to the timbre and then select it using the VALUE
+/- push buttons. Moving around again using the CURSOR +/- push buttons you can modify the velocity value using the
VALUE +/- push buttons. When a timbre is to be completely excluded, set the velocity at 0. It is advisable to use the
Left Drum function when the Arranger is not in use.
F5 Autochord: This excludes the acknowledgement of the chords leaving the Accordion player free to play the bass and the chords
manually, without any automatism.
F6 Bas Sust: The value that can be modified using the VALUE +/- push buttons indicates the length of the Sustain on the manual
bass, when the MANUAL BASS push button is in use (LED lit).
F7 Bas To Ch: Set as On, it also includes the bass note in the acknowledgement of the chords, to create chords with varied bass using
the BASS TO LOWEST push button.
F8 Bas Octav: The value that can be modified using the VALUE +/- push buttons indicates the octave of the manual bass timbre, with
the MANUAL BASS push button enabled.
F9 Lower Oct: For each timbre assigned to Lower 1 and Lower 2, its octave can be modified using the VALUE +/- push buttons and
push button F9 to switch between the two parameters.
