DESCRIPTION

The loopback midi driver makes it possible to create special purpose virtual midi devices based on user land server processes.

INTRODUCTION

MIDI loopback devices are like named pipes or pseudo terminals. They are grouped in client and server device pairs. The server side device must be open before the client side device can be opened.

    SERVER SIDE DEVICE

The server side device is used by some special application (such as a software based MIDI synthesizer) to receice MIDI events from the applications that want to play MIDI.

    CLIENT SIDE DEVICE

Client applications such as MIDI players open the client side device when they need to play some MIDI stream (file). The client side device behaves like any "ordinary" MIDI device. However it cannot be opened when there is no program connected to the server side.

COMPATIBILITY ISSUES

MIDI loopback devices differ from "normal" MIDI devices because an application is needed at the both ends of the loop. The loop device will return a "Connection reset by peer" error (ECONNRESET) error. Applications designed to be used as loopback based server applications can/should use this error (returned by read or write) as an end-of-stream indication.
