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.

Zone Settings

Setting Description
Instrument Select a built-in sound for testing (if MIDI is disabled)
Channel Select the zone's MIDI channel (if MIDI is enabled)
Order Choose the order of the zone's progression. Default is left-to-right, top-to-bottom.
Hold When enabled, keys in this zone will act as switches, remaining held until pressed again.

Mute Zones Select zones to mute when a key is pressed. It is suggested a zone mutes itself when playing > 1 voice.

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. Find out more here.
  • 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. This article explains how.
