This controller kb was the last of its generation, when companies cared about how good their controller keybeds felt and performed. Massive functionality with 4 zones, 4 MIDI outs, and on and on. It's crazy how powerful this thing is, especially on stage. The A70 is made for the road. Pop in a couple of Roland's expansion cards and you've got a fully functional multi-timbral synth as well.
While I appreciate your curiosity, please Google it.
Thanks
