Saludos Amigo... Apollo lo que dice nuestro amigo
MJUAREZH36 ahorita M-Audio està fabricando buenos equipos y los controladores son bastante buenos, èstos te traen un editor para la PC que es bastante amigable y te dejara programar full el controlador para mover tu XP50.. Yo te recomendaria (una opinion muy personal) el:
KEYSTATION PRO88
*key hammer-action, velocity-sensitive keyboard
*24 MIDI-assignable rotary controllers
*22 MIDI-assignable buttons
*9 MIDI-assignable Alps faders
*MIDI-assignable pitch bend and modulation wheels
*MIDI-assignable foot switch and foot pedal inputs
controllers assignable to MIDI controllers, notes, transport controls, *program changes (including LSB and MSB), sys-ex, and RPN/NRPN
*independent MIDI channel assign for all controllers
*four keyboard zones for layers and splits
*multiple dynamic velocity curves
*large custom LCD displays controller number, assigned controller, edit icons and edit values
*10 memory locations for saving all controller assignments
*sys-ex memory dump transmits the complete memory contents for backup purposes
*free Enigma editor software for unlimited storage
* +/- 11 semi-tone transposition
*dedicated buttons allow program and bank changes on the fly
Control Mute function mutes the output of all controllers so you can position them to the desired value before tweaking
*Snap Shot button transmits all current controller settings
*Fader Drawbar mode reverses the faders for realistic operation of organ emulators such as NI B4
*MIDI In port
*MIDI Out port can drive external MIDI gear or be used as USB to MIDI Out interface
*General MIDI 1 and 2 compatible
*USB class compliant—no drivers required for Windows XP, Vista (32 bit), or Mac OS X
*drivers also included for Windows 98SE, ME, 2000, XP and Mac OS 9
*powered via USB bus (cable included) or optional 9V power supply
*lightweight for its features—only 47 lbs.
Espero te sirva nuestra ayuda....
