I know you are joking
Naw..but if you are an individual that has several multi-timbral synths, it is nice to be able to dedicate a MIDI OUTPUT to each device. That is one of teh reasons I loved the MPC 3000/60. You get all of this with the 2500 but you now get the added feature of setting the MSB/LSB per track. I use the Motif ES-R, XV-5080, FantomXR, and the Proteus 2000 (6,8,9,10 banks of preset sounds respectively). Using the MSB/LSB settings and program changes for each track, I have easy access to several thousand sounds without leaving the MPC 2500. If you are into sampling sound modules, you can run the outputs of the sound module into a mixer or AD/DA converter..and run the outputs of one of those to the INPUT of the MPC 2500. Thus using the INPUT THRU function to sample these synths (while the sequncer is playing or stopped) into the MPC 2500. No, you don't need these functions..but these are great to have for MIDI heads.
But..back to the MPC 3000. I will most likely get another one day and get it customized by Forat.
