I am not aware about the use of ARP. I mainly play modal ( symphonic modal) so lets say I play a performance in this scale ( marwa) C D-flat E F-sharp A B c. Will it be possible to trigger ARP witch will use exclusively these notes, in this scale there is no fifth for example. As we can not compose the montage ARP, I have some doubts.

? What do you need to do? Are you even sure an arpeggiator is the tool to get what you want to happen?

I thought I was clear. As will say monsieur de lapalis after me, to use ARP that will fit with the modal scale I use, in the case of marwa,( in C ).
the ARP should use only
C D-flat E F-sharp A B , if There are extra note like G , it will sound false.
Is it possible to trigger such ARP ?

No, I'm sorry you are not clear. An arp can be made to only work with the notes you put in. So if you don't put in a G, where in the world would it get one? This does not tell me what you think an arp is or does. But if you only input those notes, those are the notes that come back out. Make sense? The instrument does not make decisions on its own, you are the one that inputs the data.

Mister de lapalis once again. I thought ARP was a preprogrammed serial of note! Are you
mocking me !

Not mocking you. On the contrary, you have shown a lot of disappointment about a feature and apparently you don't know what it does. Very curious. They are not just pre-programmed, but follow the rules provided by the musician interacting with them. A "sequencer" plays preprogrammed notes, an "arpeggiator" takes input from the keybed and shapes the output of the notes according to the "convert type" rules. It cannot not add a G, if you define the rules for it to follow without a G. The question you ask is almost rhetorical.

So I could use the type 1 and 3 for my purpose and I will get only the notes of the mode I play. Let's say I play a pentatonic mode, I will get only the 5 notes of this modes, does not matter the pre-programmation of the ARP .

There are three main Arpeggio playback types

Playback of played notes only The Arpeggio is played back using only the played note(s) and octave notes.

Playback of a programmed sequence according to the played notes These Arpeggio types have the several sequences each of which is suited for a certain chord type. Even if you press only one note, the Arpeggio is played back using the programmed sequence— meaning that notes other than the ones you play may be sounded. Pressing another note triggers a transposed sequence using the pressed note as the new root note. Adding notes to those already held changes the sequence accordingly. Arpeggios with this playback type have “_N” at the end of the type name.

Playback of a programmed sequence according to the played chord These Arpeggio types created for use with Normal Parts are played back to match the chord type determined by detecting the notes you play on the keyboard. Arpeggios with this playback type have “_C” at the end of the type name. Arpeggios for Normal Parts

You seem to selectively ignore that a mode (scale) is different from a chord (notes struck simultaneously)... Depending on the Type of arpeggio you select your results will vary. And as the manual warns, you will have to actually engage the Performance arpeggio and interact with it to determine what it is set to do.

There are certain arpeggios based around the rules of music theory, which includes the musical fifth as a so-called 'safe' note; there are arpeggios that strictly follow the pitches entered, and no others. There are 10,000 arpeggios on board. 3200 of them are drum/perc arps.
