Also I don’t think the Yamaha arrangers have the ability for 2 footswitches on the swell pedal and/or the second swell pedal which can be programmed for other things. (Although you may be able to find a work around using a separate Midi box, but it is much easier if it is built in as standard)
As to sounds, the age puts it around T4/5 level. (Although being different instruments requires different priority’s)
