As a pro entertainer/musician for more years than some of you have been alive, I can assure you that I, and many of my counterparts, never needed more than 61 keys to perform any song. Calling any keyboard of this stature a toy is an insult to not only the manufacturers who invested an enormous amount of time and money into it's development and production, but also to the many, many pro musicians that perform daily using a 61-key arranger keyboard. If you MUST have more keys in order to perform a song, maybe you should have purchased a piano, or a CVP. And, if your wish is to extensively reprogram every sound in the keyboard to fit your wish list, then maybe a 76-key synth midi'd to a PC or Apple is what you really need. I, personally, know hundreds of Pro players throughout the world, and none of them ever wanted to become software engineers in order to earn a living with their arranger keyboards. Essentially, we just want to plug them in, power up and kick off with the first song of the set - nothing more, nothing less.
Now, I, for one, made a damned good living performing with a 61 key arranger keyboard. I worked more than 450 jobs a year for many years, supported my family, built a home out in the sticks on 5-1/2 acres of wooded ground with a trout stream running through it, purchased a sailing yacht, and still managed to stash enough money away for my eventual retirement. And, it it were not for my failing health and a terminal illness, I would still, at age 77, be on stage performing 7 days a week with a 61 key arranger keyboard.
For full-time entertainer/musicians, the advent of a 61-key arranger keyboard made life a lot easier. I once owned a PSR-9000 Pro - it was brutally heavy, bulky, difficult to transport and didn't provide any more features than any 61-key keyboard of the same era - It just had more keys, some of which that rarely were played. For home players, the number of keys may be an important factor, but for those of us out there performing every day, those extra keys don't make a bit of difference in the grand scheme of things.
The 61-key arrangers were much lighter, had the same features, sounded just as good, they were much easier to carry and transport, took up less space in the car and cost a good deal less money. What's not to like. At one time, I had an 88 key controller attached via midi to my 61 key arranger, and quickly came to realize that I mainly played in the middle 61 key area of the 88 key controller. 88 key controllers were designed to satisfy piano players - not arranger keyboard players. The controller was taken back to the music store the following day.
I anticipate that Yamaha will come out with a new PSR model that will have all the features and sound of the Genos within the next few years. You can bet your bottom dollar it will sell like hotcakes! Unfortunately, I will not likely be around to see or hear it, but for you youngsters out there, I think you will really have lots of fun with it.
All the best,
Gary
