I got another reply from the Ritmo developer Chris, trying some suggestions (nice guy), so after looking at this page, I sent him a link to here. Thanks Jerm.
Also to make it sound more stereo, I've been adding in my plug-in window the free stereo simulator carbonized vst plug that you can download here:

I also like to add their Dynamics plug and Chris' free Crunch plug (with sublte touches) for really punchy drums.
P.S. Chris' site linked to an awesome free drumkit that you can use for free as a DLS/Soundfont:

If you have Ritmo, you can choose your favorite samples of the newest kit there. It has lots of different samples of each drum at different volumes, but these are fairly large downloads:
