Again, the main purpose of BiaB is to recreate the sound of real musicians playing real instruments.

The RealTracks in particular, are actual recordings of real musicians and real instruments, adjusted by software to match the pitch and timing of the chord progressions you define. There are MIDI data to go with these tracks, but that MIDI data is just an approximation to what the musician actually played, though it may well still help with what you want.

MIDI tracks and MIDI-Supertracks are intended to be actual MIDI and might better suit what you want, depending partly on whether the synth idea you have is polyphonic or a monophonic.

As far as synthesizer sounds go, there are countless synthesizers out on the 'Net that can be controlled by the MIDI you choose. In many ways, it's the "morphing" of the synthesis that sets its character, so controlling that is definitely (IMHO) a task for the producer, rather than a tool like BiaB.

Whether you use a software synthesizer or a physical synthesizer is probably personal preference.

I think, personally, that trying to include a rich set of moderns synthesizers into BiaB would, at best, be a never-ending process of "add a synth"; "it's too dated"; repeat.

I think you really need to find synthesizers on the 'Net' or from a hardware manufacturer to get the sounds you want, and then use BiaB's MIDI to control the notes and the DAW's automation to control any morphing. There are free software synthesizers out there, as well and a large number of commercial offerings.
