From the Gigasampler Forum:

Regarding the Sonic Implants 24M GM Soundfont set, like Frank, I am very unimpressed. As I said in another post, the only two instruments that I like are the t-bone and the soprano sax. By comparison, I much prefer the 8 Meg Emu set supplied with the Soundblaster Live.
It is a shame that Jammer Live does not seem to want to work with GS. Even using the Hubi drivers, MIDI communication just will not happen. I have no trouble at all with Cakewalk - AND - all program changes work faultlessly (with the full GM set pre-loaded). When a new sequence is loaded (from within Cakewalk, not by dragging it onto GS), it is ready to play instantly. If Cakewalk can work, it seems logical that Jammer could be made to work as well if Soundtrek were motivated to do so.

While Frank is understandably disappointed that the GS/Conexant/JLive does not seem at this point to be a viable replacement for a Yamaha PSR-9000, I cannot agree that the Conexant GM kit suffers by comparison with the 4 meg Roland set or any soundcard in my acquaintance. I have been putzing around with GM sets for years and I can tell you I am DELIGHTED with the Conexant set!
