NAMEaseqnet - ALSA sequencer connectors over network
DESCRIPTIONaseqnet is an ALSA sequencer client which sends and receives event packets over network. Suppose two hosts connected by network, hostA as a server and hostB as a client. The ALSA sequencer system must be running on both hosts. For creating the server port, run the following on hostA:
sequencer opened: 128:0
Then a user client 128 with port 0 was opened on hostA. (The client number may vary.) For creating the (network-)client port, run aseqnet with the hostname of the server:
hostB% aseqnet hostA
sequencer opened: 132:0
Now all events sent to hostA:128:0 are transferred to hostB:132:0, and vice versa.
The ports created by aseqnet can be connected arbitrary to other sequencer ports via aconnect(1). For example, to connect hostB:132:0 to a MIDI output device 65:0:
- hostB% aconnect 132:0 65:0
Then events to hostA:128:0 will be delivered to hostB:65:0. The following command plays MIDI on hostB.
- hostA% pmidi -p 128:0 foo.mid
The multiple clients may exist simultaneously. If hostC is connected as a client to hostA, events from from hostA are sent to all connected network clients, i.e. hostB and hostC. However, only one connection is allowed from a client to a server.
To disconnect network, stop all clients before server by ctrl-C or sending signal to them. The server will automatically quit.
