Not compatible with libasound2? #3

Open jamestunnell opened 11 years ago

jamestunnell commented 11 years ago

I installed alsa-midi on Linux Mint 15. All of the libasound packages I have available to install are libasound2. Those are installed (libasound2, and libasound2-dev).

So when I require 'alsa-rawmidi' it complains that libasound.so isn't found. I tried making a symlink to libasound.so.2.0.0, which is the actual .so file installed. This makes the error go away so I can require alsa-rawmidi, but it doesn't show any MIDI inputs or outputs. AlsaMIDI::Input.all returns [].

So is there an older libasound I need to be using instead? Is compatibility with v2 planned?

I'm using Linux Mint 17 64-bit.

$sudo apt-get install libasound2
$sudo apt-get install libasound-dev

Then to see MIDI Devices, according to: http://tldp.org/HOWTO/MIDI-HOWTO-10.html

$sudo modprobe snd-virmidi snd_index=1
$amidi -l
Dir Device    Name
IO  hw:1,0    Virtual Raw MIDI (16 subdevices)
IO  hw:1,1    Virtual Raw MIDI (16 subdevices)
IO  hw:1,2    Virtual Raw MIDI (16 subdevices)
IO  hw:1,3    Virtual Raw MIDI (16 subdevices)

Examples

$ruby list_devices.rb

MIDI setup works pretty nice playing midi files: http://tedfelix.com/linux/linux-midi.html FluidSynth version 1.1.6

But i cant get sound from the examples/output.rb
