Frequently Asked Questions
How do I connect the controller to Ableton, Logic, or FL Studio?
Use the wireless WebRTC connection by entering the 4-letter pairing code displayed on your computer, or connect via USB. Any DAW that accepts standard MIDI input will recognize the controller instantly.
Does the arpeggiator sync to my project tempo?
Yes! You can choose between Internal BPM or MIDI Clock Sync. In MIDI Sync mode, it detects incoming pulses from your DAW to keep your sequences perfectly in time.
Can I use my phone as a wireless sustain pedal?
Absolutely. The app features a dedicated sustain pedal control (CC64) with toggle/hold modes and polarity inversion, making it a perfect portable replacement.
Are my layouts saved between sessions?
Yes. The builder uses persistent local storage to save your pages, grid sizes, and MIDI assignments automatically. You can also export layouts as JSON files for backup.
What is “Slide Expression” on the pads?
Slide Expression allows you to send CC data like Mod Wheel or Aftertouch by sliding your finger vertically or horizontally while holding a pad, enabling highly expressive playing.
