aseqnet - ALSA sequencer connectors over network
aseqnet 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 run-
ning on both hosts. For creating the server port, run the following on
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
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 fol-
lowing 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.
