Detailed Description

Switch to Manual

A sequencer of notes over time that will send its note on/off events to instances of a Helm native synthesizer

Member Function Documentation

◆ AllNotesOff()

override void AudioHelm.HelmSequencer.AllNotesOff ( )

virtual

Triggers note off events for all notes currently on in the referenced Helm instance(s).

Implements AudioHelm.Sequencer.

◆ NoteOff()

override void AudioHelm.HelmSequencer.NoteOff ( int note )

virtual

Triggers a note off event for the Helm instance(s) this points to.

Parameters

note	The MIDI keyboard note to turn off. [0, 127]

Implements AudioHelm.Sequencer.

◆ NoteOn()

override void AudioHelm.HelmSequencer.NoteOn	(	int	note,
		float	velocity = `1.0f`
	)

virtual

Triggers a note on event for the Helm instance(s) this points to. You must trigger a note off event later for this note by calling NoteOff.

Parameters

note	The MIDI keyboard note to play. [0, 127]
velocity	How hard you hit the key. [0.0, 1.0]

Implements AudioHelm.Sequencer.

◆ Reference()

override IntPtr AudioHelm.HelmSequencer.Reference ( )

virtual

Reference to the native sequencer instance memory (if any).

Returns: The reference the native sequencer. IntPtr.Zero if it doesn't exist.

Reimplemented from AudioHelm.Sequencer.

◆ StartOnNextCycle()

override void AudioHelm.HelmSequencer.StartOnNextCycle ( )

virtual

Starts the sequencer on the start next cycle. This is useful if you have multiple synced sequencers and you want to start this one on the next go around.

Implements AudioHelm.Sequencer.
