MK-300 : Nice for the price

Overall, this is a good keyboard to start learning on. It is nice that it ships with a power supply.

The keys are responsive, the built-in functions are intuitive, and it offers a lot of flexibility without being too complicated.

I did have one issue initially; when I put batteries in it, it wouldn't power up. One of the positive battery contacts was not contacting the post of the battery. I remedied this by prying up the contacts with a small screwdriver, and it powered up no problem.

It has the two features I really wanted; velocity-sensitive keys and USB MIDI. It would be nice if it had an audio line-in, but that's a small thing.

Another nice feature is how well-designed the stereo speaker system is. If you hit a key on the left, the sound comes more from the left. The same is true for the right and center.

It is also nice that all of the voicings, styles, and such are printed in the instruction manual.

I plugged it into my computer, and it was immediately recognized in Reason, EZKeys, and EZDrummer. Good stuff.

Overall, I am very happy with this keyboard, especially for the price.
