How to build a remote control unit for the Eventide Orville This document describes the use of the MIDI Sysex protocols offered by the Eventide Orville which are suitable for a PC or Mac based remote control system Be aware that actual computer programming may be required to make use of them These protocols may also be offered on future Eventide audio products and are in general independent of software versions The text below refers often to Orville but should be taken to apply to any of the supported systems They are currently supported by the following Eventide Products Orville V2 705 or later DSP7000 7500 4000B all Eclipse V1 1 or later i The Orville operating system is made up of userobjects These may for example display a value give the function of a push button or act as a menu page Userobjects have the following features ii Each one is identified by a unique ID number known as the key ii They usually contain some data in various formats iv Each one contains a statement which is a C type format string to be used in displaying their data This may be empty v Each one contains a tag which can be used as a label for buttons This may be empty vi There are a number of different types of userobject See below for detailed information vii A userobject of a particular type also has a subtype This can usually be ignored viii Some userobjects are read only or constant these display inform
