How do I increase the number of MIDI through ports in ALSA?

Question

ALSA always creates 1 MIDI through port. Since I work with Windows music applications via Wine, and because MIDI through ports are everything-proof, how can I increase the amount of MIDI through ports created by ALSA?

Answer 1

$ modinfo snd-seq-dummy

description:    ALSA sequencer MIDI-through client

parm:           ports:number of ports to be created (int)

Answer 2

Adding midi through ports:

1. Install missing alsa components:
   • sudo apt-get install alsa-oss
   • sudo apt-get install (alsa missing components if it nessessary)
2. run text editor as administrator:
   • sudo kate (or sudo gedit or sudo somethingtexteditor)
3. In text editor type line:
   options snd-seq-dummy ports=16 (ports=as many as you want)
4. Save the text file to /etc/modprobe.d/Nameyoulike.conf
5. Close text editor
6. Reboot
