Addictive Drums II: MIDI Standards Out the Window?

Ever since MIDI arrived in the 80s, the keys for individual drum parts have been standardized. (Except maybe when XG changed things a bit.) So here I am with a MIDI drum track I recorded in another program. The bass, snare and high hat are correct, but any toms are playing as cowbells, tinklebells, and phhhttt sounds.
 
Is there a quick trick I can use to fix this? Or am I doomed to manually sliding things up the piano roll scale?

In the AD2 UI, click the ? in the upper right and select "Map Window"
Then pick GM from the "Map Preset" drop down in the upper right of the Map Window dialog.
To make GM the default, there is a button in the bottom right just above the OK/Cancel buttons in the Map Window dialog.

The MIDIPacks are installed in AD2 available in the Beats window.

Lets say you have the following snare articulations:

• Edge
• Middle
• Center
• Rim-shot
• Side-stick

Now double the amount of articulations for separate left and right hand samples.
If you do samples with the snares off, you've again doubled the articulations.
 
The only way you're going to squeeze that into a GM map is to use MIDI controllers to switch articulations.
Depending on the MIDI controller the end user has available, this can be easy or a major pain.
For many users, it's simpler (easier) to have each articulation mapped to a separate MIDI note.
Important to keep in mind... this works with any MIDI controller.  
There are no absolutes... it's all a judgement call.

Since I started using AD2, I'm liking it more and more. And it doesn't bother me that the GM map is being relegated to the legacy shelf. I love the many variations of percussive elements.
 
Even though I'm 63, I've always embraced innovation and improvement. Many of my peers hate computers because they can't keep up.
