I've had a look at the Roland RD300s on the internet and it only has 8 instruments. All these instruments are also keyboard instruments such as harpsichord, piano, clavinet, etc. This means that if you direct BIAB to play your Roland, it can only use those 8 sounds.

Unless I'm reading the information wrongly, it's not possible to get BIAB to get your keyboard to play guitar, strings, clarinet, etc.
