Using File Utility as a Plug-in Software (Windows) You can start the File Utility software as either a stand-alone software or a plug-in application in the Open Plug-in Technology compatible application. Refer to the owner's manual of the client application (sequencer, etc.) for details on using the File Utility as a plug-in software. About Open Plug-in Technology Open Plug-in Technology (OPT) is a newly developed software format that allows control over MIDI devices from a music software sequencer. For example, this allows you to start up and operate various parts of your music system, such as plug-in board editors, and mixing control editors - directly from an OPT-compatible sequencer, without having to use each separately. This also makes it unnecessary to set MIDI drivers for each application, streamlining your music production system and making all operations more convenient and seamless. About the OPT Levels The client application and its compatibility with OPT can be divided into three levels, as shown below. Level 1 - OPT Panels provides basic support for opening and displaying OPT control panels that can transmit data via the clients' external MIDI ports. Typically this will allow basic hardware editor control panels to operate properly. Level 2 - OPT Processors provides support for real-time MIDI processors and panel automation. Typically this will allow both real-time and offline MIDI effects (e.g. Arpeggiators, transposers etc.) to operate properly and supply automation to OPT panels. Level 3 - OPT Views provides support for edit views and MIDI processors/panels that require direct access to client sequencer storage structures. Typically this will allow sophisticated MIDI edit views to be supported (e.g. List editors, Auto Accompaniment, Data Checkers etc.). OPT Level Implementation for the File Utility This chart shows the OPT-compatibility of the File Utility. OPT levels of the client application File Utility operation Operation support Operation limits VIEWS (Level3) Yes None PROCESSORS (Level2) Yes None PANELS (Level1) No - n Certain operations may not work as expected if there is no corresponding function in the client application (sequencer, etc.). The highest level of implementation for the client application is indicated in the OPT logo (which appears along with the version information in the application). 4
