More broken than working?

I def. like the per-channel stuff, and the note display btw (could e.g. be logged to MIDI as well that way Smile)

You hacked that into the C sources yourself right?

If my C skills weren't seriously lacking I would e.g. have a PSG<>SCC vol. balance slider on my player already, instead of the 3 webNEZ PSG options. One day perhaps.. Wink

I'm (still) dissatisfied with libkss's PSG. NEZplug sound much better in that regard IMO (though not sure how realistic it is; there's a pretty big difference between the 2 MSX PSG types there).

Hmm, yes it's amazingly bad all of a sudden, last time I tested it worked fine. :O Might have something to do with the browser version...?

The per channel export stuff is in libkss, okaxaki implemented it when I requested it. Smile I managed to get it working partly myself as well before that I remember, but that was a huge hack. My C skills are lacking as well. Wink

The notes are calculated with the pitch in Javascript, search for pitch in the msxplay-bundle.js. I remember I didn't like it yet, when having vibrato it'll change all the time, I guess that can be improved with some tricks.

Edge seems to work a bit better then Chrome, at least playback starts all the time...

This is my 100th message on msx.org. Running Naked in a Field of Flowers

Edge is not know to respect the W3C standards and norms.
It is therefore preferable to refer to Chrome and Firefox to determine the functioning of a site.

Chrome doesn't manage memory properly. Especially on Mac.

Well, Edge is based on the Blink engine these days, which has been created for Chrome, so that's the same. And I agree about the memory management thing, but I guess it's my own fault in this case, the site is just an experiment. I noticed it's also very bad on Edge. However I got it stable when reopening the site a few times, no idea why... some timing issue I guess.

@Ren, some info about the per channel export here.

Have you seen this other experiment btw? Would be nice if this had a spectrum analyser...

Just include the one line of Javascript and all zip files with vgm files in there will be detected, downloaded, extracted in memory and offered in a overlay player.

Ha, yes, thx, I remember those GitHub issues/requests Smile

I'll def. look into that some time. Next to visualization, note recognition, I think it's pretty nice to be able to change volume levels per channel, and e.g. being able to save that to a preset.

Yes, I'm, aware of vgmplay-js as well Smile
I also read (parts of) that forum thread @ vgmrips.net where vampirefrog mentioned they will be using libvgm as JS replayer. Since libvgm is pretty much finished now, and already powering the latest vgmplay, I figure they'll come up with their Emscripten version soonish?

Anyway, you did your vgmplay-js yourself from the (now) legacy source code right, I figure shouldn't be too hard to figure out how to build it myself, but really would need to find some time to sit down with that. (My player *does* still need a core to support .vgm Smile)

mmontag/chip-player-js seems interesting as well (to learn from perhaps as well).
