Potrebbe essere valida una LINE6 FBV Express MKII, che anche se nata per chitarra sembra programmabile in termini midi anche per altri usi?
Il MIDI è uno standard quindi se è ben programmabile (come sembra ad una prima occhiata del manuale, almeno a livello di MIDI CC) direi di si, non conoscevo quel modello della Line6 e sembra niente male.
Controlla solo il discorso Program Change, se è ben supportato. EDIT: Direi di si a giudicare dalla figura a pag 4-6 del manuale e dalla lista di possibili comandi:
MIDI Command: The type of MIDI message the Control will transmit. You can choose between the following types of MIDI commands for all Footswitches (note that Pedal Wah, Pedal Vol, and Pedal 2 Controls offer only the MIDI CC and Unassigned options):
• Unassigned: Sends no MIDI data. Basically, this is to disable the Control. If you don’t plan on using some footswitches or pedals within the preset you are creating, it is best to set these to Unassigned to avoid unexpectedly triggering functions in your targeted software!
• Bank Change: A numerical value typically used to load a Patch or Preset Bank.
• Program Change: A numerical value typically used to load a Preset within a selected Bank.
• MIDI Continuous Control (MIDI CC): A set of Value and Range numbers commonly used by MIDI software and hardware to provide access to parameters.
• MIDI Machine Control (MMC): Specific commands for commonly used for controlling things such as transport parameters and mechanical functions (Play, Stop, Record, etc.)
• Mackie: Specific commands in the “Mackie Universal Controller” format, commonly used for transport parameters and mechanical functions (Play, Stop, Record, etc.), for MIDI software that supports the Mackie Control format.
