[alsa-devel] [PATCH 0/3] ALSA: oxfw: add support for TASCAM FireOne

[Takashi Sakamoto]

Hi,

This parchset adds support for TASCAM FireOne to ALSA OXFW driver. PCM and
MIDI functionalities become available including physical controls. The
first and second patches are preparation for it.

This model supports some extra commands. So as the other ALSA drivers for
sound and music units on IEEE 1394 bus, they should be implemented in
userspace applications. For your information, I note them:

(Jog/Shuttle display mode)
./firewire-request /dev/fw1 fcp 0x01ff0000022e46493110ffff
response: 000: 0c ff 00 00 02 2e 46 49 31 10 06
 * The last byte is:
  * 0x00: always off
  * 0x01: always on
  * 0x02: breathe
  * 0x03: metronome
  * 0x04: MIDI clock rotate
  * 0x05: MIDI clock flash
  * 0x06: jog slow rotate
  * 0x07: Jog track 

(Control surface mode)
./firewire-request /dev/fw1 fcp 0x01ff0000022e46493111ffff
response: 000: 0c ff 00 00 02 2e 46 49 31 11 00
 * The last bytes is:
  * 0x00: FireOne native
  * 0x01: Mackie Human User Interface emulation

(Input monitor monaural)
./firewire-request /dev/fw1 fcp 0x01ff0000022e46493112ffff
response: 000: 0c ff 00 00 02 2e 46 49 31 12 00
 * The last byte is:
  * 0x00: off
  * 0x01: on

(Firmware version, read-only)
./firewire-request /dev/fw1 fcp 0x01ff0000022e46493113ffff
response: 000: 0c ff 00 00 02 2e 46 49 31 13 02
 * The last byte is:
  * 0x02: version 2


I can see additional commands from Windows driver. They seem to be used to
retrieve the name of data channels.
