Improved Workflow

The H9 workflow is built around four core modes: Select, Perform, Presets, and Parameters. Together, they create a faster, more performance-ready experience for browsing presets, organizing sounds for live use, and controlling effects in real time. With HotSwitch and HotKnob macro control, plus flexible footswitch behavior, H9 feels less like a menu-driven processor and more like an actual instrument.

The H9’s various routing options make it easy to slot into pedalboards, amp loops, hybrid rigs, and studio setups. The pedal supports stereo, MIDI, expression and aux control. It’s compact enough to simplify a board, yet connected enough to anchor a modern rig.
