Hi Paul,

I've managed to get SampleTank changing patches. As suspected, it's all to do with the STMP files. I haven't yet created my own STMP file (although that looks pretty straightforward), I simply used one that came with Omnisynth 2 and that sets SampleTank to emulate General Midi sounds.

What I did was the following ...

1. Load in a BIAB song file that has a melody.

2. Set a general midi synth as my default synth. (I used VSC/DXi. I did this because BIAB likes to have a soft synth installed as a default synth.)

3. Put SampleTank on the "Melody Track" in the VSTi setup.

4. Setup SampleTank for General Midi using Ominsynth 2 as per THESE INSTRUCTIONS.

5. Exit VSTi.

6. Go to Piano Roll Mode.

7. Select "Program" as shown below.



8. Click on the timeline at the position that I want the patch change to occur (I didn't worry about what instrument it said at this point in time).



9. Hover the mouse over the patch change until I get then double-headed vertical arrow shown below.



10. Left-click and drag the double-headed arrow up/down to obtain the sound I want.

11. Play the song.

Hope this helps,
Noel

P.S. Paul, thank you for inspiring me to do this. I'll put the information over under "Tips and Tricks" in case it's useful for others.
