DOES THE 2500 HAVE ENOUGH INPUTS/OUTPUTS...

HERES MY DEAL...I HAVE MY 2500 AND A MIDI KEYBOARD CONTROLLER. I AM TRYING MIDI A FANTOM RACK, A MOTIF RACK AAANND A TRITON PRO KEYBOARD. IS THIS IN ANY WAY SHAPE OR FORM POSSIBLE???

If you dont intend to use all 16 midi channels available in each unit, you could create a midi daisy-chain. I wont go into details here, but you can utilise the midi thru ports on any of your synths to 'pass on' or 'thruput' midi signal to other devices.

Investigate 'Midi daisy-chaining'.

This type of question would normally be posted in 'Studio Environments'.

Don't type in caps, its irritating on the eyes and looks like you're shouting.
