# aseqnet(1)

ALSA sequencer connectors over network

## 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)](/aconnect/1.md).** 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.
