Sorry, I got the name wrong. It's
Audio Phonics at www.guitarwitch.com
and as the name now implies, the full chromatic version has gone. It is also only W95/W98. Not XP/Linux/Mac
However, the comment about download sites applies, and using Webferret as a multisearch engine is rewarding (that's how I found it again) and free. Copernic can pay dividends, too.
Hope I still have it on disk!
