HD24/96 Technical Reference

11

All the other controls have been addressed in the Quick Start Guide. Refer to that guide for their descriptions.

Rear Panel

The I/O slots and connectors for the remote, footswitch, keyboard, mouse, and monitor are explained in the Quick Start Guide. Here are a few more details about what you’ll find on the rear panel.

BNC Termination Switch

The Termination switch on the Sync card selects whether the BNC input is bridging (high impedance) or terminated (75 ? input impedance). Press the Termination switch in if the HDR24/96 is the last device in the clock chain. If a clock is connected to other devices, leave the Termination switch out and terminate the last device in the chain.

MIDI Connector

The MIDI IN and OUT ports terminate in a 9-pin D-Subminiature connector on the rear of the MIDI Interface card. The pinout for this connector complies with the convention used for MIDI connections to the game port of a standard sound card. The adapter from this connector to a pair of standard 5-pin MIDI connectors is readily available at computer stores. Some sound cards use a 15-pini D-Subminiature connector, so be sure that you purchase the correct adapter.

Ethernet Jack

This is for connection to a 100 BaseT Ethernet network. See Appendix C for detailed networking setup information. Note that the same connector type is used for the optional remote controllers for the HDR24/96. Don’t mistake these two connectors!

Accessory Slots

Of course we left room for future expansion. Stay tuned.

Graphical User Interface (GUI) Overview

After plugging the keyboard, monitor and mouse into the rear panel connectors and booting up the HDR, you'll find most of the MackieOS GUI is pretty darn similar to the rest of the computing music world. Typical paradigms of left and right mouse clicking, menu bars with pop-up or pull-down menus, dialog boxes, scroll bars and high resolution graphics all make for a familiar interface.

The GUI layout is easy to learn and is designed with minimal layering of windows and functions. The Menu bar atop the screen contains everything that can be accessed within the interface. Mouse click on the menu item, pull down, select and release (or re-click) will kick things into action or call up another window or dialog box. For the power users, keyboard shortcuts to most GUI menu items are available and are listed in the menu as a reminder for next time.

Right-clicking with the mouse is context sensitive in many areas of the screen. While everything is available with a left-click, right-clicking frequently offers short cuts to operations you’re likely to need to perform next. While exploring the GUI, right-click and see what happens. It’ll probably give you just the choices you’re looking for. Left click actions are usually dictated by which one of the 4 tool choices is currently selected.
