Hey I've been working on a simple sequencer for gba and I'd like to share it. It's in a very early but usable state. I've actually been sitting on this for months but didn't have the right hardware to test it before releasing. The plan is to add a few different sync options for lsdj etc, and a tool to add new samples without recompiling everything.

Ideally when I have the time I'll post the source up on github or something but my internet access is kinda sporadic at the moment so hopefully this'll do for now.

It's experimental and buggy and will probably trash other saves on the same flash cartridge. But for sure you can make some beats on a gba.

Download gba rom here:

updated version 0.02

I'd be interested to hear some feedback.

From the release notes:

A step sequencer for gba, using samples on the directsound channels.

I wanted to make something closer to a drum machine than a complete
workstation like lsdj. The main features i wanted was to have sync
modes for connecting to other devices, and be able to arrange patterns
into songs and chains like lsdj.

tested on visualboyadvance and no$gba and on a real gba with ez-flash II cartridge

what works:
-pattern sequencing & playback
-song/chain sequencing & playback
-in-program sample swapping
-song mode / live mode looping
-saving/loading
-pitch shifting of samples
-panning of samples
-volume of samples
-copy/paste patterns and orders
-random pattern generation

well well well, a contender! I will definitely be trying this out. when you're doin' sync options, make sure it'll work with NL2 if you can

Great I will test it, I like the idea.
And please make it syncable with nanoloop 1.x, 2.x because it will add lots of opportunity.
And share the source on GitHub too.

Nice.
I love stuff that is built like LSDJ. And i love samples.
Gonna get myself a flashcard to play around with it on real hardware. Wanted to get a GBA one anyways for a while now.

Looks promising! Looking foward to nanoloop2 sync and custom samples patching.

I love this. Are there any decent GBA flash carts out there?

I looked into the EZ-Flash IV. Flashcart with a MicroSD Slot. Should be the most reliable one, since a lot of people use it.

Cool!

Please upload on git, would be very cool to check it out.

Yes. If you can find one, the EZ-Flash IV carts are awesome. They come with an odd StarWars GUI skin but can be changed to any custom GUI you want. Even make your own.

just curious, how'd you do that? I thought slot 1 flashcards couldn't boot GBA roms...

Tested on gba with the good old supercard sd.
Works fine, and it's really fun, I think the sample are well choosen.
What is needed :
- a key repeat for the keypad ;
- when your cursor is at the most left return automatically to the right, same thing for the cursor on the right ;
- change sample volume, could be global for a channel ;

This could be a real tools if you can inject sample in the roms easilly or fetch them from the mass storage FAT filesystem.
Hope you will release the source on github or drop it on your google drive, because I like this kind of stuff, really.

Gosh if there was a way to combine this with the DMG channels on the GBA it would be sooo epically epic..

Still epic though. This is really cool. big_smile syncing this with a Gameboy would be muy excellent
