Beams & Notes

Beams & Notes

The coloured Beams represent musical notes. They surround you in space along a horizontal circle, like an equator. To put it another way, imagine you have a harp that warps around you, or you are in the centre of one of those circular keyboards.

There are two ways to play MIDI notes. When you first touch a button in the Bloom, the note represented by the beam centremost on the screen will be triggered. While your thumb is held down, additional notes are triggered by moving the device along the horizontal circle surrounding your body. When the centremost beam crosses the centre of the screen while the thumb is held down, that note is “plucked”. The note that was playing prior is stopped and the new note is played.

Calibrating the Centre

Beams remain fixed in space even as you move. This means there is a fixed centre position and fixed left and right boundaries. If you wish to re-position these along the horizontal circle (like for instance, if you hand your device to someone sitting opposite you), you can do so by “recalibrating the centre”…

There are three ways to recalibrate the centre:

  • Suspend and resume the AC Sabre
  • Exit and re-enter the main instrument view by going to the MIDI Connection or Settings via the buttons in the corresponding QuickPanel
  • Manual recalibrate by pressing the “Center” button in the corresponding QuickPanel.

Note Sustain Concept

Note play in the AC Sabre obeys a “monotrigger” paradigm. Each note trigger causes the previous note(s) to be stopped. Sometimes this involves multiple simultaneous notes (such as with Harmony Articulations). It’s also possible for portamento style synth patches to have AC Sabre make a small overlap between ending notes and starting notes.

There are various ways of sustaining multiple note’s simultaneously, even when you remove your thumb from the Bloom. See the Legato Mode and Drone sections for more details…

Why can’t you sustain multiple notes at the same time?

In short, you can…by using the Drone. However, if one desires to let the all triggered notes “ring out”, like a harp, then it’d be better accomplished by increasing the “release time” on your synthesizer/sampler’s amplitude envelope.
