Changing System Sample Rate Affects Playback Pitch

[yosagenom]

First of all, thank you so much for resurrecting Game Music Box for OS X Lion and up.
I used to use this for my .nsf playback and I loved it, but has been unable to do recently so I really really appreciate this ! (I know there are other players out there, but GMB works the best for me.)

The problem that I have is that I set audio sample rate setting on my system to 48000hz, and seems like it affects the playback and it plays everything about a half step up. Like when you drop an audio file with 44100hz sample rate into DAW with 48000hz sample rate setting. I know just need to keep the setting to 44100hz but I do quite a lot of music on my computer and I kind of need to keep it higher sample rate for better quality.

If I export the stems everything sounds fine even with 48000hz setting. My system is OS X 10.9.3 running on my mid 2011 iMac.

I hope this will be helpful for you and thanks again for an awesome app :)

I'm working on fixing this on my fork

Thanks @uyjulian. I hadn't noticed this bug. There are lots of places where 44100 is hardcoded that should be fixed.

[uyjulian]

Yeah, the audio code is really tangled up, I might end up rewriting it to use OpenAL.

[yosagenom]

Thanks guys. I'm glad to know you guys are still on it. I hope it's not too much of a work.

[uyjulian]

nah, no worries!
I'll work on this this weekend.

So, the issue hasn't been resolved yet within the app I presume.
Usually specifically when using playback only on the app, changing the rate setting of the output in MIDI and Audio config in usr/applications/utilities does the trick. But at the same time, it can be frustrating if you want to keep 48000hz at all times and not going back and forth. I noticed this when I was using my Fast Track M-Audio USB Card. Again, huge thanks for bringing the app back. It was one of the main reasons I did not upgraded my system for such a long time.

Try Cog for an alternative to this player: https://kode54.net/cog/

[NiGHTSaturn]

Thank you! Cog is great! It's great to have a nice looking player that can play Midi files OPL style and more game consoles! The question I have though, I can't seem to find channel control or export to wav on the App. These features are not a part of Cog?

[uyjulian]

I don't think that those features are part of Cog.

[dgventura]

I've fixed the app so it plays with normal sound at 48khz now. Is anyone interested in this?

[NiGHTSaturn]

Absolutely!!!

[dgventura]

Ok, I'm finishing an update of the iOS version now. Will update the binary here for download when I get the Mac version ready for release.

[yosagenom]

dgventura, thanks so much for working on this! Looking forward to the update!

[NiGHTSaturn]

Let us know when it's ready 👍

[dgventura]

It's getting there. ;)

[NiGHTSaturn]

WOAH David! This looks marvellous! If you need any help let me know!

[dgventura]

Thanks. There's lots I want to get done for version 1.0. Could probably use some help with testing.
