Re: [PATCH v2 00/37] ALSA: Add MIDI 2.0 support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello I have a few questions:

1. As default, USB-audio driver will take the alternate setting for MIDI 2.0 interface:  Does this mean that the ALSA driver will default to Alt Function 1 if it exists ? 
2. What happens when using a kernel that does not support Alt Function 1 (MIDI 2.0) and  device with a  (much longer) MIDI 2.0 descriptor is attached ?
3. " However, user may let the driver falling back to the old MIDI 1.0 interface by a module option, too."
     Can or how it this done via the ALSA API  ? If the switch is made, does an ALSA client require to re-enumerate all the ports ?
4. Is there a way to force a specific device (port) to Legacy MIDI 1.0 ?
5. Is there a way , via ALSA, to select UMP MIDI 1.0 protocol instead of MIDI 2.0 UMP protocol.
6. To which protocol does the driver default ? UMP MIDI 1.0 or UMP MIDI 2.0 ? 
7. Does the driver do anything related to  Jitter Reduction ? How/is this supported via the ALSA API ?a
8. Does the driver do anything related to  Bandwidth restriction ?  How/is this supported via the ALSA API ?
9. Are/will UMP streaming messages be supported ? (new feature in MIDI 2.0 specification), if yes, how ?
10. Is function block information supported via ALSA, i.e added in the ALSA Port information ?
