About Open Plug-in Technology

Open Plug-in Technology (OPT) is a software format that enables you to control MIDI devices from a music DAW

application software. 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. OPT also makes it unnecessary to set MIDI drivers for each application, streamlining your music

production system and making all operations more convenient and seamless.

In addition to the original OPT, there is also Open Plug-in Technology Version 2 (OPT2), designed for use with the

Recall software. Studio Manager is a host application that supports OPT 2.

❏ About the OPT Levels and Overview

The host application and its compatibility with OPT is 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 client’s external MIDI ports. Typically this will allow basic hardware editor con-

trol 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 to operate properly and supply auto-

mation to OPT panels.

Level 3: OPT Views provides support for edit views and MIDI processors/panels that require direct

access to client program storage structures. Typically this will allow sophisticated MIDI edit views to

be supported.

OPT-compatible plug-in software is connected directly to an OPT-compatible

host application.

❏ About the OPT2 Overview

OPT2 is a software plug-in format that is a further development of OPT Level 1 (Panels), and adds

functionality that allows Studio Connections to be implemented.

Plug-in software compatible with OPT2 is indirectly connected

to the DAW application compatible with Studio Connections,

via the Studio Manager.
