Hi !

Nice to have been usefull.
The Quartet mode means all YM registers (except ports) set to 0 except that in register 7, tones are allowed on the 3 voices (not noise).

Cheers,
Paulo.

I remember the debate and didn't understand because I'm not a YM2149 tracker expert.

Are Voices On = 125KHz AC; and Voices Off = 0Hz DC ?

If this is the case, I understand exactly what you are doing. Hatari currently
demodulates everything above 80% nyqist rate, and returns the same values
for DC. Correcting the Voices Off DC is easy, I'll look into it for the next version.

The last paragraph is incorrect, here is the correction:

If this is the case, I understand exactly what you are doing. Hatari currently
demodulates everything above 80% nyqist rate, and returns correct values
for Voices Off = DC. This is because Voices Off (reg 7) causes the YM2149 to produce
a non-zero DC output voltage; independent of frequency (registers 0 thru 6).

Hi !

Nothing much to add lately, sorry.

I just attached on the first post another 16 voices MOD you can play with Hextracker at 10.7 KHz on STF and 12.5 KHz on STE and that i found quite enjoyable.
The original module, also included, used a lot of notes outside the 3 "standard" Protracker octaves so it had to be converted.
This kind of conversion is not done automatically yet as it can be quite complex. I hope to add this feature someday.

Cheers,
Paulo.

Thx, thx, thx, thx, thx, thx,
I will check it out today!!!!! :) :) :)


____________EDIT___________
Ah, one more thing - as usual we're waiting (when You have some free moment of time ;) for self-repeating keyboard for the tracker. I tried to write the "funky" 8ch MOD entirely with HEX but due to the lack of keyboard usage, finally I had to switch into STE (Octalyser) and finish the music there. But my main machine is 520ST (don't worry - it has 4Mb ;) ) and although I have 1040STE, I use mostly the 520, so I'd be grateful for having the full keyboard procedure, at some point. Thanks.

Hi !

This is just to inform that there was a minor bug update to allow the import of 6 voices Octalyser MODs: tag CD61.
I was unaware of that tag until a few days ago.
Please check the first post for the updated files.

Bye,
Paulo.

Thanks.

Well, one minor update in 18 months was not much.
As free time is not in great supply not much is to be expected soon.
I made a bit of clean up to the first post so now for version 0.844 only the full package is available.
For people using the .ST disk images, now the package uses two of them.

Bye,
Paulo.

Hey there. Now that I've got my 40mhz STacy back together and running,
I've been trying out some of the cool looking software I'd been missing.

Is Hextracker not supposed to work on '030 machines? So far, I can't get it
to work on my STacy. It crashes with 2 bombs.

Thanks!

Hextracker runs on the Falcon and I would assume the TT ( with STe sound )

Have you tried the output settings? Setting for STFM not E

Thanks for the reply. The problem is, I can't get to settings (or can you change an .inf
file somewhere?) because it crashes when you start it, with 2 bombs...

Hi !

From the sound SW point of view, the program should work also on Stacy and TT.
The two bombs problem, bus error, is probably related to some hardware register mapping or shadow addressing when accessing an address that allows a faster access on ST/STE but that conflicts with some existing HW on newer machines.
For Falcon shadow addressing was removed when accessing the YM 2149. It is slower but as it is a Falcon there is no problem.
As you say it occurs when starting the program, the most plausible explanation is something related with the video HW registers init.
Anyway, this would need a step by step debugging.
Looking here: http://deunstg.free.fr/sct1/hardware.htm, i can see that the TT has quite a lot of new HW features but the STACY has only one note:
$FF827E|???? |STACY Display Driver |???(STACY)
Does anyone know what is different in the STACY from a "normal" ST ?

Bye,
Paulo.

Probably best to keep in mind that this is far from a "normal" STacy. :)

It has the PAK 68/3 accelerator board - 40mhz 68030, with a 40mhz 6882
math chip, and TOS 3.06 included.

It does have a compatibility option - when I get a chance later this
evening, I'll turn that on, it basically makes it a "normal" TOS 1.4
machine again, running at 8mhz.

I'll post the results when I get back (have to go out, probably be
about 6-7 hours from now).

Thanks for the reply! :)

PS If it makes any difference, the Paula player, with Petra,
does work okay.

Hey, home now. Just tried the Hextracker package from that link you posted
(1.8megs).

Same results. I tried every .prg in the archive, the hextracker prgs both
crash with 2 bombs. The bin programs do start. do let me load a file, but
when I hit play, the speaker makes one little noise and then it all locks up,
requiring a reboot.

Now...flipping the switch, and booting up in compatibility mode (TOS 1.4
4 megs, and 8mhz 68000) all the software runs fine.

Apparently something about the PAK it doesn't like. :)

Er sorry, hadn't grabbed those - just did - try them out in a jiffy. :)

EDIT: okay, didn't fool with the one because its in .ST format. The
other one, "Twelve" crashes in PAK mode and in compatibility mode.

PS Oh, it crashed much faster at 40mhz than at 8mhz. :roll: :lol:

Hi,

except the 6-channels problem I found before, I'd like to ask You for taking under consideration such a problem -
HexTracker plays music _slightly_ faster than other trackers.
It doesn't matter when You make music from single instruments. But when You want to use _any_ loops (drums? guitars?) it makes impossible using them.

I was testing it and comparing to Amiga/PC. For instance those trackers have the same tempo (tested on loops) -
OctaMED - Amiga
SkaleTracker - PC
Octalyser - Atari STE
DigiComposer - Atari ST.

But HexTracker (and even ST_50kHz_Player, if I recall) run music faster. It's a very small difference but it 'eats' ends of the loops and songs become non-rhythmical.

I didn't find exact BPM tables on Internet, so I made some by myself (I hope they're accurate enough):

Tempo in Trackers...........BPM Speed
7...............................107
6...............................125
5...............................150
4...............................187

Those are tempos from Amiga/PC (and mentioned two Atari 16bit trackers).

I was wondering - is it possible to fix it? As the HexTracker became my the main instrument on ST series, I let myself to ask You about it.

Anyway, if You need some recordings to know what I mean, I can do that.

Hi Yermezey

In Audio sculpture you can stretch samples & make them fit a bit better, IIRC you choose fetch in the sample editor and it fits the start & end markers then you save it back to the sample. It looses the tone but you can compensate by changing the frequency.

Paulo, a neat feature may be to have a little calculator to timestretch/fit a sample to say 4,16,32,64 lines of a pattern for the base/selected frequency? :-)

Hello !

This is quite strange.
If tempo is 6 then we have 6 ticks. I am almost sure it works correctly.
I we had 5 or 7, the difference would be too big to be un-noticed (more than 10% faster or slower).
Now each tick corresponds to VBL that depends on the VBL of the computer. That changes a bit from computer to computer. European Amigas have slightly faster clocks than the American ones.
There the difference is minimum but exists for all samples not only the looping samples.
You can adjust Hextracker to play all samples faster or slower changing the reference sample freq set with the default value of 9855. For European Amigas, it should be 9900. I showed the calculations once in a topic here.
This would explain why you might find differences with other STE replayers.
But this apllies to ALL samples.
You can also test your looping samples in the SAMPL sub-menu and change the repeat start and looping size.
Please also keep in mind that BPM and Finetune are not supported by Hextracker.

If all this does not work, please provide a simple MOD with one pattern, one looping instrument where you can notice differences with other trackers.

That SAMPLES FREQ parameter acts as global TRANSPOSE.
If you change that value to 19710, the MOD will be played one octave up.
If you change that value to 4928, the MOD will be played one octave down.
The original idea was to allow better samples to be used instead of the low sampling frequency Soundtracker samples.
If you used better samples then the global result would also be better.
Higher SAMPLE FREQ is more CPU consumming but not much.
50KHz replay is only possible with SAMPLE FREQ values close to the default 9855 due to the speed techniques used.
The minimum replay frequency to use the major high speed technique also used by Lance is directly dependent on that parameter:
Minrepfreq = Sample_freq * (2^(20/12));
For 9855, we get 31288 Hz.

Explaining better:
- 9855 Hz is the reference sample frequency to get a D# of the middle octave
- if you sample a C of the middle octave, then you should sample it at 9855*(2^(-4/12) = 8287 Hz
- if you sample a B of the middle octave, then you should sample it at 9855*(2^(8/12) = 15644 Hz
=> as you can see the 31288 value corresponds to the B of the top octave


Bye,
Paulo.

By the way - does the Sample_freq (FSampl option, I gather) save along with the music?
Or should it be type in every time the MOD is loaded?

By 'F' sample you means setting the speed F06 > F04 ? yes always set those in the pattern first thing.
