Hello Fernando.ot be I wrote a shell for fluidsynth called fluidterm that sends/receives from the tcp/ip interface. I can ship you the source if you like. I'm on holiday now in Hawaii, so I may not be too attentive. >>> >>> >>> Invita i tuoi amici > e Tiscali ti premia! Il consiglio di un amico vale più >>> di uno spot in TV.
