This is Cakewalk’s Instrument Definition file for a Waldorf Q series synth. The difference is that sound numbers are replaced with their respective categories, i.e., instead of "A002 Rain" it is "pad Rain". So now when you need to choose a pad, you can type "pad" in the Sonar’s instrument selection box and see all sounds in this category. In other words, if you need a lead, for example, you don’t need to remember that "Trennkost" is a lead as opposed to, say, pad or bass. Makes life a lot easier.
The file is based on an original version by Fredrik Haglund posted on Waldorf’s site (I hope he does not mind - let me know if it is not so).
