External MIDI Control - of Fader Parameters
From software version 2.5, all fader assignable parameters can be remote controlled via MIDI Control Change Messages.
To be able to control Faders you must create a dedicated Fader User Group holding these parameters. Page 20 in this
manual section explains how to create User Fader Groups.
Single Precision - Double Precision
We support both single (7bit) and double precision (14 bit) Controller Data, but you should notice that best resolution is
achieved using 14 bit Controller Data. By controlling parameters with Single precision you will be able to control in 128
steps for a complete parameter range. For most applications this will be quite fine and this is also the precision most
external controllers and especially sequencers support. This is called 7 bit precision.
However, System 6000 supports the 14 bit precision standard that has a considerably higher resolution: 128x128=16384
steps.
To achieve this resolution via an external fader control the external controlling device must be able to handle two
controllers at the same time on the same MIDI channel. The scheme below shows which controllers to assign to which
Faders for both Single Precision and Double Precision situations.
MSB value indicates the actual double parameter change. So sending a LSB will not change
the value, but only cache this value for later use when receiving the MSB part.
The LSB must therefore be sent before the MSB.
