Hmm, isn't this just a standalone version of Soundbox, with a different (admittedly much better) UI, and Javascript export stripped out for whatever reason? I'd say just use the original and make some music for 4k intros with it.
No idea. It does say that it's based on Soundbox, but I've never used one or the other so I can't say. I recently got a bit hooked on ORCA by the same developer (https://hundredrabbits.itch.io/orca) which I can totally recemmend! While browsing their repos I found this and thought it might be of intertest to the tracker-loving community here.
ORCΛ is far and away my favorite software sequencer. I've been wanting to do a track with that and mGB for a little while now. I've done some noodling to that effect already. One of the first tracks I did with ORCΛ was for the DAFM Sega Genesis-based synth (though mine uses YM3438):
I was instantly enthralled by ORCΛ's concept, but I wasn't sure I could make the sort of tracks I had in mind, based on seeing it's typically used (frankly, in a far less boring way than how I intended to use). It did, however, prove versatile enough for me to cobble together some machinery by which to compose and perform in a way that didn't require too much livecoding or demand for accurate timing in cueing sequences. I'm not sure that I'll be doing so much composition with it, going forward, but I'll definitely be using it to sketch sequences to be used in composition or for producing more generative pieces.
