Tiny keys are definately out for my big hands and I'm leaning towards a Casio PX3 with a Roland BK7M module so I can feel like I'm playing a solid keyboard. A question---
If this is the same as the PA50SD why not just go with that and get full keys, is it price?
Having had a lot of experience with Yamaha's PSS series, which use similar small keys, it's not just the tinier size that is a problem (for me-I have large hands), but it's going back playing on a "normal" size keyboard that will be a real issue for most players.
Small keys are extremely bad for your technique, but, if the Micro Arranger is the only instrument you play, it will probably be just peachy.
There is also the well known issue with the shorter throw keys not being very good for velocity sensitive piano type voices.
If you plan on gigging with it, you still need to take a stand, foot switches, powered speakers (unless you're playing in a very small room) and there is also "the look" you have to deal with, as most people will think it is a toy.
I could be wrong, but I have a feeling that most "keyboard players" will use this product for a while, and then get back to something with normal size keys.
A 24 lb PA-50SD makes a whole lot more sense to me...the weight couldn't possibly be an issue (so it's probably a money thing), and it would be far easier to play.
In any case, it would be far more logical (in my opinion) to use the Micro Arranger as a module,
controlled by an instrument with
regular sized keys. Of course, then you will need a double tier stand, and will have to deal with longer setup/breakdown times.
I certainly wish the new owners all the best of luck with their instrument...it does
sound very good, indeed (like a PA-50D).
