Finalizing the installation

• After installing the software and connecting the hardware:– Log onto your computer as an administrator (Windows

NT/2000/XP users only)– Start VAB (under Programs-VAB for Infinity-VAB)

• Allows VAB to “recognize” all blocks for use in experiments

Testing the System

• On computer, start VAB (under Programs-VAB for Infinity-VAB)

• Go to “Testing the System” Laboratory• Open and go through lab worksheets (e.g. Mic and

Cosine test) and make sure everything works as indicated

• If you have problems, post questions on the Discussion Board at the Infinity Project website

Digital Music Setup• Some of our best digital music designs (e.g. in

Chapter 2) utilize MIDI (Musical Instrument Digital Interface)

• MIDI-based VAB worksheets accept MIDI music from the PC

• To use MIDI with the Infinity Technology Kit, you must install two freeware programs– MIDI-OX and MIDI-YOKE

• See http://www.infinity-project.org/MIDI.pdf for complete installation instructions
