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 running 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(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 con-
       nected 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.
