M-Audio DigiPatch [16/20] Appendix 3 mac panel software

Appendix 3 - Mac “Panel” Software

The Mac application — DigiPatch Panel™ — included with your

unit, is a remote control program that allows you to control up to fif-

teen units through MIDI system exclusive messages. It requires a

Mac with a 68020 processor or greater, System 7.10 or greater, and

supports the following MIDI drivers:

Mark of the Unicorn’s FreeMIDI version 1.2 or greater.

Opcode’s Open Music System (OMS) version 2.2 or greater.

Apple’s MIDI Manager 2.0.2 or greater.

Standard Modem and Printer drivers.

Operation is straightforward. There are two modes of MIDI commu-

nication:

1) Single Ended Mode. In this mode the computer doesn’t really

know (or care) about how many DigiPatch units are connected. It

depends on you to tell it how may units are present, and how many

Patchbay Windows to create. It transmits one-way system exclusive

messages, and never waits for an acknowledge or reply. This mode

is convenient when you want to control your DigiPatch unit(s) from

your computer and when ‘MIDI In’ cables and connectors are scarce.

2) Two Way Mode. In this mode the computer scans for DigiPatch

units using system exclusive messages, and creates a Patchbay

Window for each unit it finds. Upon initialization, each window

reads all programs and the edit buffer contents from its correspond-

ing unit into the computer’s memory, and saves the data into the

application’s preferences file (in the System Preferences folder). If no

units are found, the program reverts to Single Ended Mode and cre-

ates one or more Patchbay Windows, depending on the contents of

the preferences file.
