Main Tab

The Main tab contains additional settings for the program and the layers.

The settings of the Range and Modifier sections are saved with the project in your host application. The Voice, Glide, and Pitchbend settings are saved in the Backbone program.


In this section, you can make trigger settings for the program.

Low Key

Sets the lowest key on which the program is triggered.

High Key

Sets the highest key on which the program is triggered.


The settings in this section are saved in the project in the host application, not in the program.


This section allows you to modify the incoming MIDI notes.


Here you specify which note on your external keyboard triggers C3. This is useful because C3 is the default MIDI note on which the factory presets are based.

For example, a kick drum preset has its original sound defined at C3. If you want to use the standard GM MIDI note C1 to trigger this sound, set Note to C1. With the default Note setting, the kick drum sounds two octaves lower.

Fixed Note

Activate this option if you want all incoming MIDI notes to automatically play C3.

Fixed Velocity

If this option is activated, you can trigger the layer with a defined velocity value instead of the incoming velocity.


If Fixed Velocity is activated, you can specify the velocity that triggers the program in this value field.


The settings in this section are saved in the project in the host application, not in the program.



Activates monophonic playback.


If Retrigger is activated, a note that was stolen by another note is retriggered if you still hold the stolen note when you release the new one. This way, you can play trills by holding one note and quickly and repeatedly pressing and releasing another note, for example.


Retrigger is only available if Mono is activated.


If Mono is deactivated, this parameter determines how many notes can be triggered simultaneously.


If the maximum Polyphony setting is exceeded, the notes that were played first are stolen in chronological order.

Trigger Mode

Defines the trigger behavior for new notes.

  • Normal triggers a new note when the previous note gets stolen. The sample and the envelope of the new note are triggered from the start.

    To minimize discontinuities, use the Fade Out Time parameter.

  • If Resume is selected, the envelope is retriggered for new notes, but resumes at the level of the stolen note. The pitch is set to the new note.

  • If Legato is selected, the envelope keeps running for new notes. The pitch is set to the new note.

Fade Out Time

When a voice is stolen because the Polyphony limit is reached, it is faded out. Here, you can specify the fade out time.


Glide allows you to bend the pitch between notes that follow each other. For these parameters to have an effect, Glide must be activated for the layer on the Pitch page.


If Sync is activated, you can specify the glide time in note values. This allows you to synchronize the glide time to the host tempo. To use triplet note values, activate the Triplets button.

If Sync is deactivated, you can specify the glide time in milliseconds.


Activate this parameter to glide the pitch only between notes that are played legato.


Allows you to select one of three curve types to define the glide behavior.

  • With the Linear curve, the pitch glides at continuous speed from the start to the end pitch.

  • With the Exponential curve, the pitch starts gliding at higher speed and decelerates towards the end pitch. This behavior is similar to the natural pitch glide produced by a singer.

  • With the Quantized curve, the pitch glides in semitones from the start to the end pitch.

Glide Time

Sets the glide time, that is, the time it takes to bend the pitch from one note to the next.


Pitchbend Up/Pitchbend Down

Determines the range for the modulation that is applied when you move the pitchbend wheel.

For the pitchbend range to have an effect, both the Glide and the Pitchbend parameters on the Pitch page must be activated for a layer.
