llustration Event List “Sweeprun” / Setup Data Part 16
The first three Events are used to call-up the required
sound program:
Controller 0 and 32, Program Change. Once more: the
order of these events is crucial!
Following are the volume settings (Controller #7), Pan Posi-
tion (Controller #10), Resonance (Controller #71), fade-out
time (Controller #72) and Filter Cutoff (Controller #74).
Finally we add Send Levels for a subtle dose of Reverb (Con-
troller #91) and Chorus (Controller #93).
The only Controller that appears to be missing from Part 16
is the Attack time, but this is because the initial value was
used and so didn‘t need updating.
Two drums add to this some further Sys-Ex messages,
which will now be explained:
❯
Drum kit Processing
>Bassdrum (Part09)
Position 1.03.056 = Shift (-21)
The part was used to record a typical Dance bass drum,
derived from the SEXAMPLE “HiQ”. This wave is assigned to
key D#-1. Bass drum parts are usually recorded with key C1.
The following Sys-Ex message was used to correct this:
>Complete Drum Kit (Part 10)
Position 1.03.152 = Part Mode (DrumS1)
MIDI channel 10, the channel usually assigned to drum
parts is switched to Part Mode “DrumS1”. This allows indi-
vidual setting of each drum instrument via Sys-Ex, just like a
“User Drum Set”. The next events communicate with and set
up the snare drum (key E1). To begin with, the Decay times
are shortened to make the sound more percussive. That last
Part 10 Event (position 1.03.176) tunes the snare a little
higher (+4).
Some more useful tips: if you want to copy the discussed
Sys-Ex messages into your own songs, you can change the
relevant parameter value with the penultimate Byte (before
F7H). Let‘s say you wanted to tune the snare drum higher
still. You could use a value of 46H (+6) instead of 44H(+4).
Before we deal with the next lot of bars, i.e. the musical
content, two more pointers about the playing back of
sequencer songs:
Your sequencer has to be set up to send MIDI clock signals,
otherwise the all important Performance part will remain
silent, as the Arpeggiator uselessly waits for external timing
signals.
You also should always take care that the CS1x is set to
Performance mode and not Edit mode, at least during play-
back of the Setup bar, otherwise the Controller and Sys-Ex
messages for Multi Parts 5 – 16 never reach their destina-
tion. Are you confused yet? If so, here is an overview of the
complete song arrangement:

Arpeggiator Ð vari-
ously used (Bars 2Ð21)
The intro consists largely of the Performance Part‘s Arpeg-
gio (type “Sweep Line”, MIDI channel 1), which here in con-
trast to the later bars doesn‘t run all the way through, but
stops after 5 8ths or so. At bar 4 a real-time knob control of
Cutoff and Resonance kicks in (see track “PerfContr”.
Bars 6 to 13: the Arpeggio is running throughout and is
modulated by the filter. Bass drum, HiHat and Bass join in
with a typical Dance groove (bass and bass drum take turns).
A super-long snare fill is added during bars 10 to 13. A
change is signalled towards the end of bar 13; take a look at
this selection of track 2:
Event List “Sweeprun” / Bar13
The first two Events (Controller 18) were generated by turn-
ing Knob6 (Assign2) counter-clockwise. This assigns LFO to
Amplitude modulation rather then the current Filter modula-
tion. The Arpeggio sound becomes more percussive.
The following Sys-Ex messages now select a different
Arpeggio type; now “UpDwBOct4” is in effect. The Arpeg-
giator volume is also reduced a little.
Bars 14 – 21: the changes to the Arpeggio that were pro-
grammed at the end of Bar 13 now come into effect. The
Arpeggio isn‘t triggered by constantly changing notes any
longer, instead G2 and C2 are used consistently. A periodic
filter modulation now occurs every four bars (see Parts “Fil-
ter” in track “PerfContr”).
So, the Arpeggio has fulfilled its task, no other Parts get to
have a go.
The bass sequence is now subject to filter modulation for
variety, spread over several bars. On top of that, Parts 15 and
16 now play a stereo pad.
