FAQ
Questions, answered.
Something else on your mind? Check support or write to us at [email protected].
Which devices does Glow run on?
Glow runs on iPhone and iPad with iOS 17 or iPadOS 17 or later, as a standalone app and as an AUv3 plugin. One purchase covers both. The AUv3 also loads in Mac hosts that support AUv3 instruments.
Can I use it as a plugin in my music app?
Yes. Glow is an AUv3 instrument, so it loads in GarageBand, AUM and other AUv3 hosts on iPhone, iPad and Mac. In a small plugin window it switches to a compact panel; make the window bigger to see the full panel.
How do I import .syx tone banks?
Open Presets, tap Import .syx and pick a file. Glow reads tone dumps in the original 80s SysEx format; audition any tone with a tap, then favourite, rename or export it.
Does it work with my MIDI keyboard?
Yes. Connect a class-compliant keyboard over USB, Bluetooth MIDI or network MIDI. Glow responds to velocity, pitch bend and the mod wheel, and you can hide the on-screen keys to give the panel the whole screen.
When is it out, and what will it cost?
Glow is coming to the App Store soon. Leave your email above and we'll tell you on launch day, with the price. It will be one purchase for iPhone and iPad, with the AUv3 plugin included and no in-app purchases or subscriptions.

Glow is the third. Every synth tells its own story, made the same way.
