Query: If you can play a soprano recorder, you can play this too

The only wind instrument I play is a soprano recorder, athough I can play trumpet and some other brass. The WX-5 has a fingering option that matches soprano recorder, with a few additional options, such as some keys that take whatever note you're playing and kick it up a half step or whole step, etc. I use this with the Yamaha Tone Generator that is designed for it, and I am delighted with the results. I would surely get more out of the instrument if I could actually play the sax, but I'm fine with this electronic "flutophone on steroids."
