Let’s stick with this example for a moment. Imagine you are working on a snare fill and decide that the snare

should increase by a semi-tone with each beat during the fill. All you need to do is insert Controller 006 with

the required value.

Don’t forget to reset the snare’s pitch after the final beat to its initial value (e.g. 66), as the rest of the song

will otherwise sound a little strange.

Should the fancy take you to experiment some more with the snare, try controlling the DRUM DECAY RATE

with NRPN. A value of between 80 and 100 will lend a punchy percussive edge to your snare! By the way,

both Decay 1 and Decay 2 are controlled simultaneously this way.

EXAMPLE: Drum Decay Rate, Key E1 (Analog Snare H):

Control 099 023

Control 098 040

Control 006 096

As you can see from these examples, NRPN can be used effectively and is often well worth the effort. At the

same time the XG concept’s ability to perform as far as real-time sound parameter control is concerned is

hereby proven beyond doubt.

We should also take a quick look at RPN messages and their applications. These messages can control

three parameters (see below):

Table: RPN Parameter

A peculiarity of RPN messages is that they require Controllers 100 and 101 to be set to 0. Strangely, this is

actually done with 127.

EXAMPLE: Fine Tune

Control 101 000

Control 100 001

Control 006 068

Control 101 127

Control 100 127

Fine tuning is increased by 4 cents: middle value 64 + 04 steps = 68 (Control 006).

In order to change a single parameter, the poor sequencer track is flooded with 5 events. In comparison, the

equivalent Sys-Ex message would only require a single event: F0.43.10.4C.08.00.09.07.44.F7. This gives us

a good excuse to deal with this subject in greater detail.
