Ahh, thank you very much. Are there any other quality tests like this that I can do? Im going to make sure and memorize these before I go to a store and and start playing around.
There are lots of tests, and you will have to decide how important certain features are to you. For example:
Most importantly:
Is the sound pleasing to you? Make sure you know about how to adjust it to make it more pleasing.
Is the action acceptable?
Also important:
Does the keyboard allow attaching up to three pedals with the typical functionality? Does it allow half-pedaling?
Does the keyboard allow fast repetition of single notes?
What is the polyphony? (32 is usually sufficient, but higher can be helpful if you are a really fast player).
If it has speakers, are they strong enough to reproduce the sound of the keyboard? Often the sound is better than it sounds (pun intended)! Connected to a high-end stereo system, a digital is often amazingly powerful in producing good piano sounds.
Is there good connectivity to computers? Not just MIDI and Line-out, but USB (or even firewire)
I would recommend reading the manuals of some candidate digitals. They can usually be downloaded from the manufacturter's website. This will give you an overview of what features are available in modern digitals. Then decide which one you must have and narrow down your selection. Finally, go to a good store and try them out.
