This is just a prototype, not sure how well it will work, you just need to try it out. If you have RealBand you can re-generate any section/bars you like until you find something that fits best.

This is an update with smoother bar to bar transitions, the sustain is released earlier and the last note in the bar is slightly shorter so it's no going into the next bar.
The midi files are included if you want to create your own with a different instrument.
This is in mono so the download is half the size 307meg, just add the FX you need.

Pipeline,
finally figured how to use them as "real drums"
Nice Flute tracks!
Thank you!

I wish PG would have more "in house" flutes. There are only 5 or 6 available, and most have very specific flavor.
