Oh, I don't know about the long silence, must have accidentally included it when rendering the WAV. Uh, I couldn't find the pickup you were talking about, also could you clarify what the metric alignment is? I never studied music theory yet (I'm not in high school yet).
This is something I composed. Intent on actual performance. Climax number one is not good. The rest is mid. The logistics work out though for the percussion. I used Noteperformer playback cause I was too lazy to put it into a DAW. Feedback would be appreciated.
I thought it was a great piece. However, a score is definitely helpful, so maybe consider using notation softwares for the actual music before mockup?... (just a thought). I loved the marimbas 🙂
