You can start mLAN Graphic Patchbay as either stand-alone software or as a plug-in for an Open Plug-
in Technology compatible application.
Open Plug-in Technology (OPT) is a new software format that enables you to control MIDI devices
from a music software sequencer. For example, OPT enables you to start and operate various parts
of your music system, such as Plug-in Board editors and mixing control editors, directly from an
OPT-compatible sequencer. 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.

About OPT Levels
The client application and its compatibility with OPT can be divided into three levels, as shown
below.

OPT Level Implementation for mLAN Graphic Patchbay
This chart shows OPT-compatibility of mLAN Graphic Patchbay.
All mLAN Graphic Patchbay functions work under the client applications of any OPT level (Panels
(Level 1), Processors (Level 2), and Views (Level 3)).
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).
Using mLAN Graphic Patchbay as a
Plug-In
Level 1 (OPT Panels) provides basic support for opening and displaying OPT control
panels that can transmit data via a clients’ external MIDI connectors.
Typically, this enables basic hardware editor control panels to operate properly.
Level 2 (OPT Processors) provides support for real-time MIDI processors and panel
automation. Typically, this enables 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 and panels
that require direct access to client sequencer storage structures.
Typically, this enables support of sophisticated MIDI edit views (e.g., list editors, auto
accompaniment, data checkers, etc.).
