NAME

aseqnet – ALSA sequencer connectors over network

SYNOPSIS

aseqnet [remotehost]

DESCRIPTION

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
hostA:

hostA% aseqnet
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. 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.
