Subject: [PATCH 3/3] ALSA: bebob: enable to deliver MIDI messages for multiple ports
Date: Sun, 21 Mar 2021 12:28:31 +0900 [thread overview]
Message-ID: <20210321032831.340278-4-o-takashi@sakamocchi.jp> (raw)
In-Reply-To: <20210321032831.340278-1-o-takashi@sakamocchi.jp>
Current implementation of bebob driver doesn't correctly handle the case
that the device has multiple MIDI ports. The cause is the number of MIDI
conformant data channels is passed to AM824 data block processing layer.
This commit fixes the bug.
