[alsa-devel] [PATCH]: snd_seq_virmidi.c do not use running status for virmidi raw input

[Ralf Beck]

Rationale: Not every rawmidi alsa client (e.q. Bitwig) support running 
status on input.
There is also no need for running status inside a computer.

This patch disables the removal of the status byte when decoding 
snd_midi_event structures to a rawmidi bytestream
