Hi again

Here's a real newbie question. I export the BB MIDI and open it in Cubase. I've only saved the bass and drums. Cubase plays the MIDI tracks using Microsoft GS Wavetable synth (don't laugh!).

My questions are:

1. Would it be worth my while installing Roland VSC3? Would I get better sounds? Really don't want to get too hi-tech here, this really only needs to be one step up from a metronome click!

2. How do I get to choose the instruments? Messing with 'Channel' doesn't have any effect apart from the bass somtimes going to a piano voice.

3. If I open the drum track I see drum sounds assigned to keyboard keys. Where do I get a 'map' which tells me which keys are which sounds?

Appreciate any pointers to a newbie sequencing forum if this is toooooooo tedious!

Thanks anyway

Bob
