qwertySeq() is a versatile MIDI sequencer Chrome extension designed for musicians and producers working with external hardware. Featuring 8 banks, 8 tracks, and 16 steps per sequence, it enables you to sequence MIDI notes and control change (CC) messages effectively. The extension supports Mac and Windows platforms and leverages WebMidi.js and Web Audio APIs for seamless MIDI communication and audio recording.

Key features include project import/export, playback with MIDI clock synchronization, real-time parameter adjustments during playback, and robust recording capabilities with mono or stereo options. Its intuitive interface supports comprehensive keybindings for fast workflow, enabling precise control over pitch, velocity, gate, and step enablement.

This works great with my Waldorf Rocket synthesizer module. I have tried it with a generic USB to MIDI converter lead, and also straight MIDI over USB. Both work fine. It's a nice extension for Chrome if you're looking for an easy to use basic sequencer for an external synth module.

Great for any older hardware synths.

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

qwertySeq() does not require any sensitive permissions.

Risk impact analysis details

Low This permission has no access or impact on the user's system or data, thus carrying no risk.

Risk likelihood

Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Chrome extension.
