The portable sound bank offers interesting retro sounding sounds which are greatly enjoyed by some however the voices can all sound relatively similar. When considering price and age of the keyboard, the instrument is relatively good quality and well made- yamaha always offer good quality equipment. However the PHONO output can be a little distorted and 'crackly' at greater volumes.
I love this keyboard. People love to hate mini keys, I like them, especially on this keyboard. The keys feel nice for it's size, and they're pretty sturdy.
I love the sounds. Some are very nice and soft, and others are beefy. It's small, lightweight, and idiot proof. My kind of keyboard.
I like to put it through all sorts of effects. My favorite thing to do is take a clarinet, or the sinewave patch and put it through a crapload of distortion.
I traded two microphones for this. If you can get your hands on one of these, do it.
