Layer Meta Controllers
This function introduces a number of layer meta controllers : Velocity, Pan, Volume, Sound length, Chorus amount, Reverb amount, Probability
These meta controllers are instruments that, rather than playing notes, set an aspect of another layers notes. This includes:
- Playing velocity (how hard the note is “hit”)
- Pan position
- Layer volume
- Sound length
- Chorus amount (per layer)
- Reverb amount (per layer)
- Note probability
In all cases, the value to use is indicated by the “note”. For example, for the velocity, the lowest pitch provides a velocity of 1, and the highest pitch is a velocity of 127. For the pan, the lowest pitch is a pan position of far left, and the highest pitch is a pan position of far right.
This function is a property of the layer, and is selected under the layer menu. When active, the main display will change slightly to indicate that it is not an “INST” that is being played, but a META.
The layer targetted for the property change is, as for the Arp-4 meta controller, set via the layers “midi channel” menu setting - channel 1 means layer 1, channel 2 means layer 2, etc.
The velocity controller can be used to add dynamic expression to another layer in a similar way to how a velocity split works, but allowing more dynamism. For example, a score layer with a velocity metacontroller can add on-the-beat emphasis to a random or even solo layer.
A pan metacontroller allows for arpeggios in other layers to be played at random pan positions.
The chorus and reverb amount is per-layer, unlike the Effect menu setting (which applies to all layers). This allows some subtle effects to be applied to notes.
The note probability provides a way of providing some randomness to the target layer; it dictates the probability (0-100%) that the given note will actually play.
