I don't know if this issue has been posted before, but i will expose this case: Before producing a song, i usually compose and arrange a new theme using a couple of soundfonts. When i worked with FL Studio, i've loaded them using Soundfont Player, but now that i'm testing REAPER (by the way, an excellent SOFTWARE!!) i found a VST plugin called SFZ from RGC:Audio (is the one used in Sonar if i'm not wrong). The problem arises when i put more than one instance of SFZ in REAPER, as they start to clip and trigger events to other SFZ tracks. In one ocasion something hanged and the volume raise to 100% in my mixer scaring me for a second... Anyone experienced this issues with SFZ and Reaper? is there any other confident free Soundfont player around? Thanks !!

There are problems with SFZ with multicore processors A version that works for me is on post#10 on this thread. Also, see this thread. Currently I prefer to use Shortcircuit V1.1.2 to play soundfonts, samples etc. Pete

Great 

Thanks !! I've downloaded the alternative SFZ version and it works for now.
