Attention DS users using nitrotracker and similar software

I'm thinking of starting a small production line of adapters for the little input socket on the DS. I've found something that fits perfectly into the socket and pretty much just put a 3.5mm jack at the end of it. Photos.

Works quite well with a guitar or microphone, recording into Nitrotracker.

Anyone interested in one? I guess this is just for those who can't solder one themselves hehe.

That's a good idea, I didn't realize that was an audio in. I have a soldering iron, though.

are there any sequencers for DS that arent in the old school tracker vertical style? Id love to start using my ds to make music but i cannot use trackers for the life of me
