It's fun and rewarding to keep those old machines running for hobby projects. I had fun reviving songs I wrote on Atari ST Cubase in the 90's, using an Atari emulator and the old floppies. Well done!
If you're looking for "music directly from a CPU," this is pretty close. This is just a small part of a much larger ongoing project where I build my own clone of the TRS-80 model 1, including floppy controllers, serial ports, and other accessories. Really need to put together a big video of that, eventually.
LEDs are connected directly (via a buffer) to the address/data lines, plus some signals like /sysres, /wd, /rd. They aren't super useful, but can occasionally show an interesting pattern. From what I remember, the DAC updates pretty slowly - a few kHz. alnwlsn.com/projectrepository/index.php?title=TRS-80_Model_1_-_Wilson_Expansion_Interface#Orchestra_80/85_-_April-May_2020

Wow, I had no idea a TRS-80 could produce so many voices and play a midi file! Very cool!

Cool project, cursed song.
Does one of the LED's indicate output to the Orchestra 85 DAC?
