Having seen the score up close and personal, and tried to play a bit of it, I'm ok with something less than 60.  @Fiddlerman, what tempo would you have chosen if nobody had ever said anything?

@fiddlerman, it's about post 16 or 17 in this thread, but I discovered another small issue with it, so I've recreated the mp3s (below).  They're at full speed, 3/4, 1/2, and 1/4 speed. Musescore can generate any tempo we want with a minor edit, so if somebody wants one at 40 or 50 bpm, it's easy to create.

It has a lead-in, but it does NOT have a countdown. I know of know way to generate a voice, or record one over the mp3 that it creates.  BillyG is the Musescore expert - he may know a way.

The lead in is one measure, 3 dotted quarter notes, then a triplet of eighth notes (dah,dah,dat,dit-dit-dit).  If anybody can take the mp3 (which can be made as .wav, if that works better) and record a countdown, maybe that will work.

I'd like to see the work I put into this pay off, but I'm not that attached to having my backing track be the one being used. I originally did it to try and get things moving, since you were obviously swamped.  That objective didn't quite get accomplished... But if we can figure out a way to use something like this (with whatever modifications are needed), it should speed things up for next time. If you can write the scores in Musescore, or we can figure out a way to import whatever file your program produced into Musescore, it will be MUCH faster.

I still the file extension error when I try to upload a .mscz file (after clearing cache, trying a different browser, and multiple reboots ). I'll try to send it to you in PM. I've successfully sent it in private chat to Bill Gunn, so I'll also get it to him.
