Hello. Thank you for great library. Convenient api makes me happy.
However I can't get drums work.
I added one more track to existing example and tried to setup bass drum and snare.
https://usermanuals.finalemusic.com/SongWriter2012Win/Content/PercussionMaps.htm
Generated file don't play drums sound(windows midi player) however midi notes exists in DAW(reaper).
Also when piano exists instead of vibraphone it doesn't produce sound. I tried using different channels but got stuck.
Please provide example how to make drums sound together with piano.

Currently both tracks are playing on the channel 0.
Change ".ch(0)" in the 3rd track to ".ch(9)", that is the default channel for drums.

Thank you! Channel does job!
