Agree good article but just slightly dated
In the "free" category rgc Audio's (latter supplied by cakewalk ) sfz & sfz+ are no longer available likewise Alchemy Player.
We all know that Sforzando, while an excellent SFZ player, is not multitimbral.
However, there was a thread awhile back (around or just before holidays) on this very topic (SFZ/SF2 soundfont players) and I think it was MarioD, if not apologies to whomever pointed it out, that TX16Wx is a multitimbral player
http://www.tx16wx.com/Coincidentally I got an announcement, or email (?) yesterday from KVR about an update of Synthfont 2 (which is not free) but it reminded me it there IS AFREE version of as well as a FREE VST plugin version (32 or 64 bit)
http://www.synthfont.com/Downloads.htmlAdditionally, anyone who has Garritan CAN import/convert SF2/sfz's but while it is multitimbral- you have to manually assign a sound to each channel - so you cannot load a GM SF2/SFZ once and have BIAB, RB or PT "automagically" pick the correct sound per channel/part/track like a the aforementioned apps.
Also if you have Garritan you probably have better sounds on tap anyway.
I'll have to look but I think there are some other multitimbral SF2 players around if I remember or find them I'll update.
