Hello.
I found what appears to be a glitch: I was creating a song using HILLTOP.STY, 110 BPM, and I swapped out the pedal steel in the track for instrument 627: Pedal Steel, Background 12-8 Crystal sw 065 [half-time]. Everything works fine.

However, if I set the Pedal Steel track to "direct input", when I re-generate it, it changes the tempo of the entire song to 55 BPM, and plays everything at half-time.

This appears to just be a rendering glitch. I thought I would see of other people could replicate the problem.
