This is great and an idea I've toyed around with building. I think we'll eventually see web-based music composition and DAWs in the browser take off.
As someone who's become used to composing with guitar tablature (a la Guitar Pro) instead of musical notation, it'd be great to see this mode supported as well. The fact that this has MIDI export built in is another great feature and a requirement to prevent lock-in. Good job.
I agree. High-end audio manipulation will remain native, but I think for a simplified use-case (composition, lower quality renders) the browser is a good sell.
That and the tooling is almost here with MIDI.js[1], Web Audio[2] and Web MIDI[3] as a working draft.
In fact, latency and audio quality (because of file sizes for sampling and because of available resources for synthesis) are two big limitations in a browser.
Also, we want to enjoy the capabilities of the MIDI output features, in order to route MIDI signals to Virtual Instruments on the computer (through virtual MIDI ports)
On mobile at least, it sucks (trying to force sign up, being presented with a page saying just 'unauthorized' on a link offered when you have not signed up). Also, from what I gathered, this is not an online daw or composition tool, is it?
