Utility Modes

In addition to the tuning delivery methods, Tanghīm has two utility modes. Unlike the tuning method badges (which are status indicators), these are clickable toggles in the top bar.

Osc: Internal Oscillator (Amber Badge)

Click the Osc badge to enable a built-in 16-voice polyphonic triangle wave synthesizer. This lets you hear and audition tunings directly from the plugin without needing any external instrument loaded. The oscillator responds to MIDI input just like a regular synth.

The oscillator runs alongside the tuning output, so you can use it at the same time as your other instruments. It is particularly useful for:

• Quickly previewing how a maqam or tuning system sounds before setting up instruments.
• Verifying tuning adjustments in real time as you move sliders.
• Teaching and demonstration purposes.

Hept: Heptatonic Keyboard Mode (Magenta Badge)

Click the Hept badge to remap your MIDI keyboard so that the white keys play the maqam degrees in order, starting from the tonic’s natural key position. Black keys retain their standard chromatic pitch. This mode is only available when a maqam is selected.

Most maqamat are heptatonic (7-note) scales, but on a standard 12-key chromatic keyboard, the scale degrees often fall on a mix of white and black keys depending on the tonic. Heptatonic mode eliminates this problem: no matter what the tonic is, you can play the full maqam scale using the white keys alone, making it easier to play melodies without memorizing which black keys are part of the scale.

Heptatonic mode affects all tuning delivery methods (MTS-ESP, MPE, and Mono PB) simultaneously.
