Revision 1.4, Sat Sep 21 04:42:46 2019 UTC (4 years, 8 months ago) by ratchov
Allow switching between devices without disconnecting clients. The new -F option allows alternate device to be specified. If the device is disconnected, the one given with the last -f or -F options will be used instead. Similarly, the new -Q option allows an alternate MIDI port to be specified. ok mpi@ |
