Qt 4.4.3 (Default branch)
Image Qt is a comprehensive, object-oriented development framework that enables development of high-performance, cross-platform rich-client and server-side applications. When you implement a program with Qt, you can run it on the X Window System (Unix/X11), Apple Mac OS X, and Microsoft Windows NT/9x/2000/XP by simply compiling the source code for the platform you want. Qt is the basis for the KDE desktop environment, and is also used in numerous commercial applications such as Google Earth, Skype for Linux, and Adobe Photoshop Elements.

This release serves only to rebrand Qt. The copyright has been transferred to Nokia Corporation. The icons and other graphics have been updated to reflect the rebranding. No bug fixes or optimizations have been made. Image

NAME

       oss_midiloop - Loopback MIDI driver.

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.

OPTIONS

       o midiloop_instances:
	      Specifies how many loopback client/server MIDI device pairs to be created.

	      Values: 1-16
		     Default: 1

KNOWN PROBLEMS

       None

FILES
