The Advanced Linux Sound Architecture (ALSA) - utilities
7e9bebad0b
This patch adds to switch the operation mode of aseqdump to specify how the values are shown. Namely, it allows to show the MIDI 2.0 values in two more different ways: compatible "normalized" view and percentage view, in addition to the default "raw" view. The "raw" view mode just shows the value found in the event almost as is. The MIDI 2.0 values are shown in 16 or 32bit hex numbers. The channel and UMP group numbers are 0-based, taking from 0 to 15. OTOH, in the normalized view, the 16bit or 32bit velocity and data values of MIDI 2.0 are normalized to the value fit in MIDI 1.0, i.e. from 0 to 127, but with decimal points. Similarly, the pitch wheel values are normalized between -8192 to 8191. Also, the channel numbers and UMP group numbers are 1-based, taking from 1 to 16. In the percentage view, the velocity and data values are normalized and shown in percentage, from 0% to 100%. The pitch wheel is normalized from -100% to 100%. The channel and UMP groups are 1-based as well as in normalized view mode. Signed-off-by: Takashi Iwai <tiwai@suse.de> |
