    A Windows macro-recorder utility for quick saving and loading of a COMPLETE QuadraSynth MIX. Read the Instructions for details. ( From Paul Swennenhuis )

Excel spreadsheet for the QS I've been playing around with QE and my QS7 a lot this week and I've noted that while it's nice how QE2.0 pulls up the names of programs and mixes from the sysex file, it may be difficult to remember what's in there if you're without QE2.0 and a computer and have a bunch of sounds dumped into your user bank.

Anyhow, to make a long story short, I came up with a very simple spreadsheet in Excel to remedy the problem. It uses two sheets, one to go over what's in the program banks, and another to get into more detail about the program's settings. The second page is automaticly updated when you enter in on the first page. I'll keep working on it and adding to it, but I thought it'd be good to see what people thought of it.
