vgmtrans VS mixxx

1 - There are generic-ish tools to dump/convert the with the notation like VGMTrans, but support for various internal formats/methods/effects/commands is definitely not 100%. I've used that one to dump tracks from many games across various systems and often it works fine, but sometimes an effect/track is missing for one reason or another or sometimes a game's music format simply isn't supported and people need to get hands-on.

A question answered before anybody even asks in the first place: I used VGMTrans to get ahold of all the Midi files. You can get it here: VGMTrans Github page

The two best options, in my experience, would be to use either GBA Mus Riper (yes, it is actually misspelled), or VGMTrans. Both should be able to take a GBA rom as input, and give you both midis, and a matching soundfont to go along with them. Then you can use your music editor of choice to load up said midi, and do whatever you want with it.

Here are the steps I'm following btw. https://github.com/vgmtrans/vgmtrans/wiki/Building-the-Qt-version#vs-noide

You can use VGMTrans to extract the Nintendo files to SF2 files as long as you have a Hotel Dusk ROM.

Mixxx is excellent and has pretty wide hardware support.

FYI the "limited" functionality of Rekordbox can be hardware unlocked with some Pioneer controllers.

There are quite a few DJs that use Ableton for DJing (or hybrid sets). Of course, Ableton wasn't made with DJing as its main function in mind but you totally can use it for that purpose and (with some tweaking) do everything and more that would be possible in a dedicated DJing software (like Traktor or Rekordbox or Mixxx)

I’ve used Mixxx a little bit and have been surprised how capable it is. It’s an open source project and is free to download: https://mixxx.org/

Mixxx (this one's free)

Mixxx (you already mentioned this; it's certainly a great piece of free software to test the DJ waters with and works with a lot of gear).

Alternatively, you can also use Mixxx with the S4 MK2. Mixxx is free. But instead of a Traktor control vinyl record, you'd use Serato timecode instead, as stated in the docs.

If the device is class-compliant, i.e. it follows the generic USB spec and doesn’t need drivers installed, it can work under Linux. However the free software you get with the controller (Serato, Rekordbox, Traktor etc.) won’t. The alternative is to use Mixxx. It’s free and open source. You can check their controller support. https://mixxx.org/

If you don't like any of those, aren't you glad you didn't spend the money to find out the hard way? There's more DJ software than those two, so try out these as well: Traktor Pro 3, Virtual DJ, DJUCED, or Mixxx.
