Warning: trying to read song data row -1145383 column 4

repeatedly with increasingly large negative offsets, effectively freezing the program.

Thanks for spotting and reporting these! I've corrected No. 2 and 3.

I'm inclined to leave the part on Pulse Interleaving as is. You are of course correct in that moving the ld a,ixh/l up would save 8t here, but I'm concerned that it might make it harder to see the connection with the pseudo-code on the left. In the end a proper player should not be written like this anyway, because you'd still end up with an all-too-large, 10t timing difference between the skip-taken and skip-not-taken paths.

Thanks for the hard work, Shiru.

To compile with GCC/Clang, two small changes are needed. makefile:103 should read

playplayer/playplayer.o: playlayer/playlayer.cpp

and playplayer/playplayer.h must #include <cstddef> to make size_t available.

Sorry for the late reply. Shiru had already posted this, so let's continue the discussion there:

Amazing release! Great compositions and lovely sound all around. Love how, in a way, it sounds very "classical beeper", while at the same time utilizing a massive array of state-of-the-art tech.

Ah, that's a fascinating rabbit hole. Was not aware of this composer at all. Great finds, thanks a lot. And yup, GE-115 is a mainframe for sure: https://archive.org/details/TNM_General … e/mode/2up One of the last ones GE made, if I'm not mistaken.

Thanks for the detective work, mate. Do you have a .CAQ format description somewhere? I'll need that if I ever add these to Bintracker.

Ah, glad to hear there's at least one person who's exited about this! Haven't had much response about it otherwise yet. Well, that's also partly my fault because I just can't be bothered to do a whole lot of promotion. And to be fair, it's not that big of a deal in the end, as there's not all that much functionality available yet. For my part I'm really happy to finally have Windows builds though, as this was the last major challenge. From here on, it's mostly smaller, incremental changes that won't require me working on the same thing for weeks on end.

Anyway, yeah, go check out Bintracker, and let me know about any bugs you come across!

A couple more issues:

- Description of the drum column layout in phaser4.txt is wrong
- There's a lot of timing drift from the drums. It seems that there is no auto-correct, but it doesn't quite add up: even if I correct tempo manually, it's still not correct.

Also, what's the proper sample rate for drums, actually?

Ah, yes, of course. I'm clearly getting senile.

Don't think it was me who invented the rla trick. I'd be a cheap bastard and omit both the rla and the sbc a,a. Doing that could potentially open up a few more possibilities here, but with the unrolled loop, modifying 3 bytes might not be worth it. Even without that, I've got a feeling there are more possibilities hiding in those 2 bytes. I just don't see them right now. #dd 0 0 would give a pin pulse, of course, but that's probably not very useful in this setup. You could also swap bc and sp. Then #dd 0, add b/c would give duty control for example, but we already have that via phase offset, of course.

These are great! Thanks a ton for your digital archeology efforts.

1) I actually had these sitting on my hard drive, but couldn't remember where I got them from. Mystery solved. And yes, I'd say it's quite likely Pete Samson did these recordings.
4) Yes! Been chasing LINC music for ages, so glad you found proof of it.
5) Haha, I love this one. Quite possible he's right that "It may have been the first program for both generating 'music' and playing it in real time."
Btw, fixed the link to Andrew Herbert's Elliott 900 series music software collection as well. He was kind enough to put it on Github!
6) According to Discogs, the 7" is actually from 1962: https://www.discogs.com/release/3793284 … Processing Looks like 1962 was quite the year for 1-bit music, heh.

Yes, they absolutely are useful, and please do add any further findings you may come across. Aside from the mainframe era, I'm also notoriously short on info on the minicomputer era, especially non-PDP stuff. Also happy to hear about any non-1-bit music software from that time (aside from the rather well documented later PDP models stuff).
