The PSR 9000 is one terrific board. I used it on my one nighters for a year. One of the main attractions to the PSR 9000 for me was the registration memory which could be programmed to hold 512 registrations internally.

But, the weight and size issue became a real problem. That's when I realized I had to find something more manageable.

Before the introduction of the PSR 2000 I got the 740 and it did the job, but I still had to have a hard copy of the codes to get the registrations I had saved to disc. When the 2K was introduced I jumped at it to get the new operating system. And I am glad I did.

Using floppies, there is no limit to the number of registrations you can program. A single disc can hold at least 170 registrations, any of which can be accessed super fast as the OS stores them alphabetically. Plus, you can create folders (just like in Windows) to access certain areas of the alphabet without searching around. You will find other players here who set up their registrations differently or punch them in on the fly. It is a matter of personal preference and the PSR 2K gives you the option of doing it any way you want.

It has soooo many features it is hard to believe it is priced so low. UNTIL you read some of the posts here which point out that it is not built as well as some of the other boards and has the potential for malfunctioning under heavy use and transport.

Yamaha came very close to fulfilling my dream of perfect arranger. I baby mine and, so far, it has rewarded me with good service.
The jury is still out on its durability.
