Switch sounds in Preset mode
By Landon McCoy · Updated September 10, 2026
Preset mode switches complete sounds from the presets stored on Stratus, without keeping the app open.
Software preview · September 2026. This guide includes the latest app and firmware workflow. Recent changes are not yet verified as available in every public release. If your controls differ, use the update available to you; do not install development firmware just to match this guide.
Prepare your sounds
- Save the presets you want in the app and put them in the desired order.
- Connect Stratus and sync the list to its onboard storage.
- Select Preset mode from Settings in the latest app, or send MIDI CC18 value 2.

Use the controls
Turn or click the Multiknob to move between preset pairs. Tap the footswitch to switch between the two sounds in the selected pair. The onboard pair navigation provides seven pairs, or fourteen positions; MIDI recalls presets from the synced list by Program Change number.
Before a performance
Test every sound and its level after syncing. A preset can refer to files that still need installation. If Preset mode is unavailable, check that the hardware has a preset list. See preset sync.
