We sell both PianoDisk and QRS systems. Both have their advantages and disadvantages. QRS was the first one out of the gate with a combined CD/floppy system-before PianoDisk and Yamaha did. Support has been excellent from QRS. They're based in PA-about 6 1/2 hours from us. They're picking up a grand to do a factory installation for us today. We also do our own installs, but it's very convenient for us and economical to use the factory. When we've needed parts or support we've gotten it very promptly. An example-we needed to upgrade a ROM chip on the AMC (analog midi controller-the floppy/cd unit) to be compatible with a flash rom upgrade. I was talking to the Seneca PA factory, one of our guys in the shop was talking to their Naples FL office. The next morning we had two rom chips in hand via FedEx. BTW: reliability has been excellent on the QRS. Glenn Grafton Grafton Piano & Organ Co.
