Step 3 Examples of using NRPN for editing
Now let's take a look at an actual example of drum voice editing using NRPN. All of the drum sounds in Sample 1 are in the default state, and Sample 2 is the very same sequence data used to play edited drum sounds. Download both, and listen to the differences.

Sample 2

For Sample 2, the ElectKit on channel 9 uses 55 sets of NRPN messages, and the AnalgKit on channel 10 uses 103 sets of NRPN messages --- in addition to the system exclusive messages for drum setup which will be discussed in the next session. This is rather extreme, and in many cases you will not need to go this far. However in situations such as when you are copying an existing song and want the sound to be as close as possible to the original, you will need to do a lot of editing

In this example, you can immediately tell that, overall, the low pass filters are closed down and the decay has been significantly shortened, but the impression of the sound is also greatly affected by the pitch and by the amount of reverb. The sound of the drums has a decisive influence on the sound of the overall song, so this is an area that must not be neglected if you want to create good data.

In this sense, I think that this sample is a very good example, select go ahead and modify the values of the various parameters and analyze their function. This will let you get a feel for how the various items described in the specification and in the tone generator manual affect the actual sound. Now, if you do this kind of editing on your own, you may decide that it's a lot of work to enter all of these NRPN messages. If so, you should definitively try using the editing functions of "XGworks" and the tools provided by Yamaha such as "Bulk2Event." These tools will significantly reduce the amount of boring work you have to do, and I am sure that you will be able to zero in on the sound that you want. That's all for this time. See you at our next session!
