Hi Miami Mo
Do a search on SZ as the Receptor has been featured numerous times, (Make sure you also check the Software Forum) and a couple of members do use them.
It is an excellent concept and has gone down well in most circles, don’t forget to have a look at the package versions, as they include a number of VSTs, and they work out much cheaper then buying them separately. (Be aware that not all VSTs will work as yet (The main ones usually work without problems) but Muse Research are continually expanding compatibility for the remaining ones)
I would have considered one myself, however as my keyboard can load and play VSTs direct, it would be rather superfluous, but if you have a hardware board that you are happy with and wish to use VSTs, then the Receptor is easier to use then setting everything up on a laptop.
Hope this helps

Bill
