[Linuxsampler-devel] Re: SET CHANNEL MIDI_INPUT

[Mark K. <mar...@gm...>]

Replying to myself...

So I tried some more commands:

[mark@Godzilla LS-Scripts]$ echo GET AVAILABLE_MIDI_INPUT_DRIVERS | nc
localhost 8888
ALSA
[mark@Godzilla LS-Scripts]$ echo GET MIDI_INPUT_DRIVER INFO ALSA | nc
localhost 8888
DESCRIPTION: Advanced Linux Sound Architecture
VERSION: 1.13
PARAMETERS: ACTIVE,PORTS
.
[mark@Godzilla LS-Scripts]$ echo GET MIDI_INPUT_DRIVER_PARAMETER INFO
ALSA PORTS | nc localhost 8888
TYPE: INT
DESCRIPTION: Number of ports
MANDATORY: false
FIX: false
MULTIPLICITY: false
DEFAULT: 1
.
[mark@Godzilla LS-Scripts]$

[mark@Godzilla LS-Scripts]$ echo GET MIDI_INPUT_DRIVER_PARAMETER INFO
ALSA ACTIVE | nc localhost 8888
TYPE: BOOL
DESCRIPTION: Enable / disable device
MANDATORY: false
FIX: false
MULTIPLICITY: false
DEFAULT: true
.
[mark@Godzilla LS-Scripts]$

But I'm not sure how I discover the second port?

As an experiment I tried:

CREATE MIDI_INPUT_DEVICE ALSA
SET MIDI_INPUT_PORT_PARAMETER 0 0 ALSA_SEQ_BINDINGS="64:0"
CREATE MIDI_INPUT_DEVICE ALSA
SET MIDI_INPUT_PORT_PARAMETER 1 0 ALSA_SEQ_BINDINGS="64:32"

which creates two MIDI inputs for LS but one of them does not go away
when LS is killed.
