There is good reason why the banks that resulted from Layer 1 of the CS1x and CS2x Factor Performances

are printed in bold - in contrast to others, these banks are fully assigned as each Performance contains at

least one Layer. Banks Pre03, Pre07, Pre11, Pre16 and Pre20 on the other hand are only partly assigned,

as all four Layers are rarely used.

We shouldn’t forget to mention that voices from the above mentioned banks and the XG banks can also be

assigned to Layers 1 - 4 of the USER Performances as well as to Multi Parts 5 - 16.

The Material Voices and XG Voices offer a massive choice of sounds suitable for creating new Performances

as well as multi-timbral applications in Performance Mode.

If all this is too theoretical for you, get a little practise with our experiment:

EXPERIMENT:

Call up Performance P1-041 (BA:101 Bass) and select the Bank and Program parameters one-after-another. Your dis-

play will show “PRE13” and “Ba:BasIneA #41”. A glance at table “Material Voices” confirms that this is Material Voice

“Pre13 - PGM 41”. Now call up Programs #42, #43, #44 etc. and compare the display with the Voice table each time. Try

selecting some other banks, too. You will find the XG banks below Pre0.

This little excursion has actually brought us to “Programming new Performances”. A good understanding of

the Performance Mode sound structure is vital in achieving optimal sounding results from song production,

and to avoid time wasted from the confusion of finding a suitable sound for a specific track.

MIDI Events

Anyone with experience of other synthesizers will expect that Multi Program song settings are performed at

the keyboard. This approach won’t work with the CS2x. Here the Multi settings are programmed into (and

are part-and-parcel of) the song itself. The song is preceded by the Setup

, stored in its first bar. Some users

may initially find this approach confusing, but it has proven itself advantageous in practical applications.

The Setup data actually holds all the Multi Program settings that would usually be performed at the machine

in the form of MIDI Events

: Bank and Program selection, Panorama settings, Volumes, Effect Send Level

and the most important parameters such as Cutoff, Resonance, Attack and Release.

With the continued use of the term Events (i.e. MIDI messages)

, let’s discuss first the various data types you

will encounter during your sequencer productions:

The most important type of event must be the note event. This is separated into “Note on

” and “Note off”

commands, which give the actual note value. The touch sensitivity

(“Velocity”) is part-and-parcel of a Note

event.

The second group of MIDI messages are the “Continuous Messages

”, i.e. continually sent data. These

include:

• Aftertouch: Sound changes created by increasing key pressure (NB Aftertouch is not transmitted by

CS2x)

• Pitch Bend: Changing the sound’s pitch with the Pitch Bend Wheel

• MIDI Controller: “Remote Control” of standardised parameter via MIDI

Yet another type of event is the Program Change Command

, used to switch sound programs via MIDI.
