The sample set Diato has been created by Eric Bricet and Jean Yves Garet, during 2008 summer.

A diatonic accordion does not produce the same notes when you push or pull the bellows, and this makes this instrument not so easy to play... More, it has not all the semi-tones of its 3 octaves (from D2 to E5). This sound bank covers C2 to E5, because we have interpolated the missing notes (so the instrument is not "diatonic" anymore)... Moreover, we have created an optional definition which allows a proper use of basses and chords (see sidebar)

Read before use :
To play properly this sound bank of a diatonic accordion, you must know that the left keys are used to play accompaniment, and allow to alternate basses and chords. This instrument has 6 basses (C, D, E, F, G, A) and 6 chords (C major, D major, E major, F major, G major and A minor). We have kept this disposition.
In order to play the accompaniment simultaneously with the melody, we have put them on the first octave of the keyboard, with this particular disposition : the basses on the white keys (except for the B, which will be assigned to the E major chord), and the chords on the black keys (except fot 
the E major chord, assigned to the B).  Of course, the rest of the keyboard is normal.

Using this sound bank and the softwares Hauptwerk or GrandOrgue, it is possible to play a 40 keys virtual accordion, on two registrations : a normal 8' (2 reeds per note), and a plenum 16'+8' (3 reeds per note).

The authors have decided to give it freely to anyone who will find it useful.

Remark : Note that on the real instrument, it is impossible to play the two stops together, because the reeds used by the second stop are the same as the ones used by the first. The second stop adds a lower sounding reed to the first stop. Please consider this if you want to use this sound bank in a realistic way.

This soundbank has been created for the softwares Hauptwerk and GrandOrgue, and the mapping files (extension : *.organ) are usable only with these programs. However, the samples, in 'wav' format, are usable in any sampling program (for ex : Kontakt, Halion, etc...). If you create special mapping files for these programs (Kontakt, Vsampler, Halion, GigaStudio, etc...), please transmit them to us, because it will be suitable to distribute them freely to the community. But we do not accept any modification of the samples themselves. In particular, we refuse them to be reduced for an integration to a General Midi bank, or a low quality soundbank.

It is forbidden to sell this soundbank or to insert the samples in any commercial application.
