keyboard into a multi-instrument workstation. Built for traveling

musicians and harmony magicians, it offers a flexible and intuitive

way to explore musical ideas while on the go or in the studio.

## Zones



A Zone is a group of keys that share settings.



- Create a new zone by pressing on the "+" icon in the sidebar.

- Delete a zone by clicking the trash icon in the zone panel.

- Rename a zone by clicking on the name in the zone panel.

- Add keys to a zone by enabling key mapping mode with the switch on the bottom of the sidebar. After pressing the keys you would like to add, disable key mapping mode.

| Quantize   | Select from a list of scales, or create your own. Voices will be quantized to the nearest note in the scale.  |



## Notes



- Harmidi was developed as a MIDI controller; built-in sounds are meant for demo purposes and may appear sluggish or behave in unexpected ways.

- Many keyboards have a limit to the amount of simultaneous key presses they can detect.

- If you would like to control virtual MIDI devices or DAWs (such as Ableton Live, Logic Pro, etc.), you will need to setup a virtual MIDI driver.
