Just starting using NTRQ, and I'm having trouble with BMP accuracy. Does anyone have any tips or links that would help me. I've looked hard on Neil Baldwin's site, but haven't had much luck with a good focused tutorial on it.

Did you see the speed table page in the manual?

It gets pretty heavy into it.

I'll look harder the two things I found told me nothing. Thanks.

what are you trying to do specifically? There are finite tempo possibilities on the NES because everything is a decimal tempo for the most part.

WOW MAN!
The NES, and any other system that is internally synchronised via the screen refresh rate, don't really have tempo in BPM.
The granularity of the clock is either 60Hz (NTSC) or 50Hz (PAL) that means that all step lengths are a multiple of this value. As an example, a Speed of 16 (0F hex) frames/ticks/whatever on an NTSC system is 16 * 1/60th of a second = 0.266666667 seconds. In one minute that's 225 beat/ticks which I guess could equate to 225 BPM if you place a note on every step with no gaps.
