The 1-Bit Forum → Sinclair → Useful Tritone tempo's?
I've found the list of 20 tempo's in the Beepola.exe, and can edit/patch them to something more useful.
Has anyone a list of Tritone pattern tempo's? Tempo's that are divisable and in time.
I've never used the xm converter, so have never experimented with different tempo's.
This is the list of Beepola's pattern tempo's, 1-20.

Well, I guess you could use just about anything you wanted to.
In the original XM converter, the speed value is calculated as follows:
speed=(int)(2500.0f*(float)tempo*(3500000.0f/1000.0f/153.0f)/(float)bpm)+256;where "tempo" is the number of ticks per row if I understand correctly. So, eg. for 120 bpm @ 8 ticks you'd get a value of 4069.
I'll make a spreadsheet using that formula. Just changing the ticks per row.
4,8,12,16,24,32,48,64,96,128 at 120bpm and 240bpm for the 20 tempo's.
Cheers.
I'd suggest putting some 1 and 2 tick speeds in there as well. Some people are crazy for high speed Tritone abuse, and they're still sticking to the old XM converter precisely because those high speeds are inaccessible in Beepola.
Btw, would it be possible to apply your alternate SpecialFX note table as a patch, too? In combination with the Tritone speed patch it might make for a nice "FrankT's Modded Beepola" release...

Yeah, what I suggested as a thought didn't work out too well. I'm now experimenting with 1, 1.25, 1.33333333, 1.5, 1.66666666, 1.75, 2 etc. for the ticks per row. And adjusting the tempo to a useable range. The old 19 speed was 900, which I'm trying to matchat about speed 17/18. It makes the 20 speed about 741 instead of the old 713. But at least the 19 and 20 speeds are compatible/interchangeable against different time signatures.
I'll look for the SpecialFX note table in the Beepola.exe and patch it as well. I'm going to have to reverse engineer one of my old songs to get the frequency table I made. Not a problem, as I'm currently working on a demo which includes everything I've written for ZX. It will only run on a 128k compatible spectrum though.
I've had to start from scratch, as I lost all my source code for my old demo's and games.
Edit: I found my old note tables on my dropbox, in archives here.
https://dl.dropboxusercontent.com/u/949 … splays.zip
and,
https://dl.dropboxusercontent.com/u/949 … _alpha.zip
Was it this one, by any chance? Or was that for Savage?
In any case, retrieving the note table should be trivial. 25 bytes into the player there's a pointer to the music data, the note table is sitting directly before that address and is 54 bytes long.
Edit: Beepola 1.08.01, at offset 0x3a72c0 
You replied before my edit above. I found my note table.
The tempo's are here in the same version Beepola.exe. DWORD's after each B8. Reverse byte order!

0020CA10 00 C3 B8 9A 2D 00 00 .øš-I've patched Beepola with these ticks per row.
1, 1.25, 1.3333333333, 1.5, 1.6666666666, 1.75, 2, 2.5, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20.
And adjusted the tempo until I got near the old 18 and 19 speeds. Now speed 14 is the same as old speed 18, and speed 18 is the same as old 19. (Or near enough).
These are the new pattern tempo's.

Ok, its fixed now...
I'm going to do a few patches with different/compatible tempo's. To cater for faster speeds.

I've changed the ticks per rows a bit, and made 2 patches. One normal speeds but with divisable tempo's, and the other for superfast songs.

Good job, thanks Frank!
I've just patched the SpecialFX frequency table.
The one you found was just for Beepola playback, compiling a tap, bin, or source listing and it reverted to the old note table.
For compiling, the SpecialFX engine builds from source which is stored as a Unicode text string at around #22BE20 in Beepola.exe. I patched the text, and now it compiles with the new frequency table.
Going to make a patcher, so I can easily apply it to my already patched tritone tempo fixes.
I'm having a similar problem with the Tritone engine. I wanted to patch the engine to remove the extraneous out instruction after the soundloop, before the key detection, that causes clicking at high speeds. I can patch the Beepola playback, but on compiling the out ($fe),a is still there.
Just updated the archive, patched both Tritone tempo fixes with the new SFX frequency table. Same link as before.
Beepola New Tritone Tempos + New SFX Frequency Table
I've added an example TempoTest.bbsong, just a few bars of the same drum beat at pattern lengths of 8, 12, 16, 24, 32, 48 and 64. With Beepola tempo's of 2, 6, 8, 12, 14, 18 and 20. Just to show it stays in time when changing pattern length/tempo.
It's in the archive and here.
TempoTest.bbsong
The 1.75, 3.5 and 7 ticks per row are redundant. So I'm removing them. These will be the final tempo's. It allows to change from 8, 12, 16, 24, 32, 48, 64, 96 etc.

13.333333333 1 6696 4550 3476I'll redo the patches today. And release the files to patch Beepola, instead of the actual Beepola.exe's.
Here are the new patches. Just patch Beepola with whatever tempo range you want.
There's a new example TempoTest.bbsong included.
Edit: Added the SpecialFX note table patch.
Great to have these mods available as patches. Thanks a lot, mate.
I've made 7 new patches. They're based on the original tempos from 20 to 14.
They're divisable between 3/4 and 4/4, 4/4 and 3/4 time signatures. And allow for at least 4x speed increase for doing super fast effects.

Also, how about a meta patcher tool for Beepola that allows you to set your own configurations for note tables, speed values? That would basically open up a whole new range of possibilities for people who are into drone music, microtonal stuff etc...

The asterisks are the original beepola tempo's, 20 to 14. Now on 14 to 8, to allow for at least 4x speed.
So if you have a song at tempo 19, patch beepola with the 19 to 13 patch, and reduce your song tempo by 6. It will be the same speed as before, but now you have option to add 4x speed effects.
The only problem left really is the limit of 126 pattern length.
I've written loaders and patchers in C before, also bbsong to vortex tracker text converter. Just don't have much time at the moment.
Wonder if there would be a chance for beeper engines being added to WyzTracker? It already has everything there, even for note tables. Also has nice feature for using scales, you can select key and scale types/modes/triads, which highlight the notes for making up your arpeggios.
Got it, thanks!
Yes, 126 step limit is indeed quite a hassle. However I recall Chris mentioning that it would be rather complicated to fix this issue, which is why he hasn't done so until now I guess.
Dunno about WyzTracker. Since it runs AYemul at it's core it should in theory be possible. But many (especially newer) beeper engines may not fit in well with the current instrument/fx editing approach, since beeper routines are generally not frame-based (unlike AY routines).
