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 running on both hosts. For creating the server port, run the following on hostA:

"" 4 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:

"" 4 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:

"" 4 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.

"" 4 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.

OPTIONS

-p port Specify the TCP port number or TCP service name.

-s addr Subscribe to the given address for read automatically.

-d addr Subscribe to the given address for write automatically.

-v Verbose mode.
