M-Audio DigiPatch [18/20] Appendix 4 pc panel software

Appendix 4 - PC “Panel” Software

The PC Windows application — DigiPatch Panel™ — included with

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

to fifteen units through MIDI system exclusive messages. It requires

a PC with a 80386 processor or greater, Windows 3.1 or later, and

supports MIDI interfaces with software drivers that adhere to the

Windows multimedia extensions (MME).

To install the program onto your hard disk, run SETUP.EXE from the

provided floppy. The SETUP.EXE program will ask you for a subdi-

rectory to install the DigiPatch Panel™ program to, then uncompress

and install the application. Once installed, the program’s operation

is straight forward. There are two modes of MIDI communication:

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.

In all cases, DigiPatch units should be MIDI wired in a series. That

is, take the ‘MIDI out’ of you computer interface and plug it into the

‘MIDI in’ of the first DigiPatch unit. Take the ‘MIDI out’ of your first

DigiPatch unit and connect it to the ‘MIDI in’ of the second, and so

on. Finally, if you want to run the app in Two Way Mode, you must

connect the ‘MIDI out’ of the final DigiPatch unit to the ‘ MIDI in’ of

your computer interface.
