Developers Matt Dowdney and William Chu have updated the qwertySeq() Chrome extension – a simple MIDI sequencer that runs in the Chrome Web browser.
Here’s what they have to say about it:
Originally the project was started as a tool to sequence inexpensive, late eighties synths that didn’t have on-board sequencing capabilities utilizing the Web-MIDI API, the React JS library and Chrome.
The sequencer, designed for sequencing external hardware, contains 8 banks of 8 sequences that are up to 16 steps in length each. Either notes or control changes can be sequenced. There are also extensive keybindings for a more interactive experience during playback.
The current release is 0.9.0b, and future releases intend to allow saving and return audio recording.
The extension is free and available via the Chrome Web Store.
