Fresh UI overhaul with redesigned knobs, buttons, and step sequencer grid. Everything feels tighter, more responsive, and easier to tweak on the fly. New record feature to capture your jams straight from the app and share them directly from your device. Hit record, lay down a pattern, and export when you're done.
