STRUCTURE
Keygroups can also overlap:
In this case, when keygroups overlap, a crossfade is automatically applied to make the transition
smooth.
You can also layer keygroups:
Although layering keygroups in this way is excellent for creating rich textures, you may find it
easier to layer sounds in the multi simply by assigning the appropriate sounds to parts and playing
them all on the same MIDI channel.
Each keygroup has four ZONES where samples may be layered on top of each other and/or
switched between using velocity.
Different programs may share samples (for example, you could use the same kick and snare drum
in a variety of different drum programs).
As well as mapping samples/keygroups across the keyboard range, programs also allow you to
apply envelope shaping, filtering, LFO modulation (vibrato, etc.) and much more and such is the
flexibility of the program's sound shaping functions that the S6000 can be used as a very powerful
synthesiser as well.
