If the new DSP card could accept Yamaha DX Sysex algorithms and you could assign one algorithm for each of the 16 voices in the S2400, that would be incredible! Like, you could use a program like DEXED or Chipsynth OPS7 to edit FM algorithms and then load your saved Sysex files into the S2400 to tweak with the analog filters and stack algorithms and stuff! This would basically make it like having two Yamaha TX816 racks. You could get the plugin company PLOGUE on board!
