I'll want you add more drumkits, like jazz kit or brush kits (or Brushes in staff text)

This rocks. Some updates to add would be the scrape sound in soundflags for Gong, Piatti, Suspended Cymbal, & Tam-Tam, extend timpani range up higher than C4 (tenor timpani range), & even add the Rim Click for Concert Bass Drum (e.g. Ancient Voices by Michael Sweeney, etc.)

These samples are really realistic, one of my favorites has to be timps, especially with the addition of soft/hard mallets, and also xylophone, Piatti, and Timbales, are very crisp. However, with some other instruments, particularly snare, triangle and field drum are buggy. The triangle is too soft, and Field Drum and Concert snare are too ringy, and not crisp enough. Also, adding small/large sizes for Sus. Cym is good, so if we can also do that with snare, Piatti, Tam-Tam, then this would be perfect!

"Muse Percussion Unknown error; could not complete download." No error code given. Please help.

I can't download the template it keeps on erroring is this a bug?

Muse Percussion is really good. It has a lot of different instruments, supports rolls (I'm especially excited about the Suspended Cymbals, given that they didn't exist with the normal sounds), and has a decent tone. However, I have a problem with the snare drum. It doesn't really sound too much like snare drum, and sounds more like gunshots. The default snare drums sound closer to a real snare. If you could make them a bit quieter and less "gunshotty", I would appreciate it a lot.

The percussion sounds are great and includes a vast amoiunt of instruments, including a new Muse Drum Kit. However, I noticed some playback errors with this new MuseSound. Particularly, the use of articulations for the open and closed hi-hats causes the kick drum to play the same note pattern in playback. Hopefully this is improved in a later update.
