Sounds and accordion modelling
It is much more than a sampled accordion. The FR-1x models different accordion reed configurations and includes 7 treble, 5 bass, 3 chord and 2 free-bass reed footages. It also has multiple musette-tuning presets, including French, Italian, German, Alpine, Scottish, North European and folk tunings
The orchestral section includes sounds such as strings, choir, trumpet, trombone, French horn, brass, flute, saxophone, clarinet, oboe, acoustic piano, guitar and mandolin. There are also orchestral bass/chord sounds and virtual tone-wheel organ sounds.
One of the important features of the FR-1x is its pressure-sensitive bellows system. Roland added a pressure sensor and physical-behaviour modelling to make dynamics respond more naturally to bellows movement. There are eight bellows-response curves, from X-Light through X-Heavy.
