So in this example we have 6 choir tracks passing to SW1000 #1 Wave, 2 guitar tracks passing to SW1000 #2 Wave,
A bass track on SW1000 #3 Wave, and 5 string tracks passing to SW1000 #4 Wave. This still leaves us with 2 wave
ports, which we can have a few dozen more tracks of audio playing through if we wish.
So why would we do this?
Well, aside from the control of the overall volume level for each set of tracks, this method also allows you to add
block effects. As discussed in the introductory chapter, the SW1000XG has a huge number of effects which are
configured to run across a total of 5 busses + the master EQ. The effect busses and the way they are accessed and
controlled are as follows
Now the Reverb and Chorus busses are easy to understand, and to set up for either audio or MIDI parts. To select a
reverb type in XGWorks, go to the XGEditor Window, and click on the detail tab for reverb. This also allows you to
edit all of the parameters with respect to that reverb type, such as time, decay etc.
Now, using the SW1000XG mixer window, you can adjust the amount of reverb being 'sent' to each of the wave
parts, by simply adjusting the 'reverb send' knob for the wave part you wish to adjust. The same rules apply for the
chorus buss, where again you can select your chorus type, and 'send' amount to each audio or MIDI track.
The trickier stuff comes when we get to the Variation and Insertion busses.
This guide isn't designed to explain all of the complexities of the XG effects system, needless to say Yamaha
produce a full guide to XG discussed earlier called XG Guidebook 2. This goes into far more detail, but for the
purpose of this chapter we shall try to cover the basics.
The Variation buss can be configured to be either a global effect which, like the chorus and reverb busses can have a
'send' amount (the amount of effect present on the track relative to the dry signal) by putting it in what is known as
SYS or System Mode. The default mode for the Variation effect buss however is INS or Insertion mode. This is where
an effect is INSERTED into a single track, be it audio or MIDI and can as is the case with an insert, can only apply to
1 track at a time.
You may ask 'Why would I ever bother using the effect like this?' Well the reason is that in insertion mode, the effect
can have certain additional control parameters applied to it. For example should you should wish to use the
modulation wheel on your controller keyboard to adjust say the rotation speed of a Leslie Cabinet effect, you can
assign a parameter inside the effect in insertion mode to do so.
Most people (around 99% of all XG users), never use the variation effect in this way, preferring SYS mode.
The Insert effects, (1&2) work only as insertion effect types, and as such can only apply to 1 part at a time. This is
great for things like electric guitar tracks, where you may want to set up an AMP SIMULATOR on just the guitar part,
and no other, with perhaps INSERT 1, and then for example add a COMPRESSOR effect to a bass track using insert
effect 2.
Again, the XGEditor window is the place to be as it will determine which effect type is selected (you can see in the
previous diagram that the Variation is currently in INSERT mode.
