@garvalf Apple II version is in TOSEC.

@matalog uhh... in this case it'll be difficult to find. There were quite a few monophonic pc speaker music "demos" back in the day, and this stuff isn't exactly well preserved online either. Really sorry man, I'll keep an eye out for this but I'm afraid I can't help you further at the moment.

Hi mate,
Sorry, I don't know this particular program. Was it monophonic, or did it do multi-channel music?
In any case, there is some old PC Speaker stuff here: http://cd.textfiles.com/psl/pslmonthly2 … /mus_spkr/
Also, Will Harvey's Music Construction Set had the Entertainer as a demo tune, you can probably find that on some abandonware site.

Hmm, perhaps you'd be interested in putting together a Huby-PF music disk release? I've got a few Huby tunes laying around in any case. What format do you need, z80 .asm or raw binary maybe?

Also I was wondering... how does the sound work on PF? Can you use timers, like on PC?

Agreed, for some engines the IO contention adds some very pleasant overtones/harmonics to the sound.

There is indeed an RGB / VGA output (the white thing close to the ear output), but I don't know how to connect it to a vga screen.

That'd be a Molex connector, the kind of plug used to connect power to drives in PCs. Damn, they are really cutting some corners there.

I do understand the reasoning behind using a jack for audio now, though. As it's stereo, I assume they're actually emulating stereo AY output. And considering how packed the board is, they probably couldn't have fitted two RCA sockets.

Yeah, composite only is a downer, but I can kind of understand why. HDMI is not feasible for this kind of projects, because of the insane licensing fees (5000 USD per year + 1 USD per unit). VGA on the other hand is pretty much as outdated as composite, so they were probably thinking "why add another legacy port". But I agree, would have been nice-to-have.

Not using RCA for audio on the other hand is indeed a bad choice, didn't realize they use jack.

Sounds good to my ears wink Yeah, it's normal that it'll play a bit faster/cleaner on +2A, because that machine doesn't have that I/O contention issue.
Btw you probably know this already, but just in case - in Beepola, you can enable IO contention emulation in the options, then the sound will be closer to 48K/128K.

Whoops, that sold out quickly! Well, good for them. I think it's an excellent project at a very fair price, made by some very experienced people.

Wow, it sounds excellent! Well done, mate.
Can't help with porting Portfolio Manager, unfortunately - my PC programming skills are extremely limited.

It's probably just akward wording/translation, quite sure they mean regular beeper tunes.

On the other hand, if one wanted to take the rules literally, then a tune made with fluidcore/wtfx/qaop/etc would do the trick, since those are technically digi-engines big_smile

Youtube would be a good option, I think smile

Yes! So the day has finally come wink
Ummm... I don't have a Portfolio. Is there an emulator that can run this, and/or could you share a recording of the sound?

Ah yes, of course. I remember having to modify the .bmp, just could't figure out how anymore. So thanks for the reminder.

Well said, my friend. That's indeed one of the reasons I'm hooked on 1-bit music. There's a lot of uncharted territory waiting to be explored.

"digital modules" hehehehe I'll give them some digital modules big_smile Probably not though, got too much stuff to work on atm.

Perfect, this is exactly what I had hoped for. Thank you very much!

One little question, is it still possible to configure the color scheme? The current scheme isn't bad at all, but I like to work with a black background.

So them folks at Culturachip where having themselves a nice little 1-bit compo - without informing us, grrrrr! Anyway, some nice tunes were made, so check it out:

I see. So it makes sense that there is detune if the 0-delay is omitted - but that should be a self-detune, not a cross-detune, no?
Also, what do you think about "correcting" the other channel's counter when a pulse is triggered? I don't think it'd even need to be accurate, just decrement the counter by roughly ((pin delay length/undelayed sound loop length)+1) and if it overflows, jump right into pin pulse generation for the other channel (+ timer update as required), else skip the other channel update.

Excellent! I find the new block system very intuitive, and it will indeed help to speed up the (already fast) workflow.
Btw, how difficult would it be to display an automatically generated block list to the right of the screen (accessible with some hotkey, for faster navigation in the song)?

Hmm, I don't even understand why this doesn't cause massive cross-detune all the time.
That said, wouldn't it be possible to combine the pins after all, by adding up the delay values of both channels?

Edit: What exactly are the values that get fed into the variable delay? Is the delay for the 0-pulse some kind of inverse of the 1-pulse, ie the longer the 1-pulse delay, the shorter the 0-pulse one?

Neat, I'm especially surprised you managed to balance the volume between the sampled drums and the tone channels.
I'm still pretty bad at reading other people's code, so I'll need a bit of time to really dig into the code.

Also noticed there are some UI changes... got any plans with that, or is it just changes in SDL?

Yeah, there's the 1-bit AVR synth. Also, the famous 1-bit groovebox has some very crude means of syncing to a midi clock. There might be others as well.

Tadaa, here we are again with our popular series "Fixing the quattropic converter". In this episode, expert C++ coder utz will try a completely rewritten, all-new algorithm for determining the play mode! Be sure to have a good laugh at the latest bugs!

Hey gensek, welcome aboard! Yes, as garvalf said, you actually only need a Speccy (and perhaps a mixer/amp so you can boost the signal a bit when loading wav files created from .taps). However, tape/wav loading is slow and tends to fail frequently when doing it in loud environments, so if you plan on doing more work with 1-bit and/or playing this stuff for live shows, you might want to get a divIDE or divMMC for faster, more reliable loading. (The page I linked to is the original manufacturer, but there are other sellers/manufacturers as well, just google it).

Very interesting and pleasant sound! Wavetables are nice and good, but this is something that's uniquely 1-bit/beeper sounding while at the same time moving forward in terms of technique. Would definately use an engine with this.
