To tell you the truth, this is a really good protable keyboard. The audio quality is great on the piano & synth. It's very good for it's synth! I particularly loved the drums. The dance drum kit really stuck out as a good one for rap/r & b. and of course dance music. The rock drum kit and electric one are cool too. The sound effects are really nice too....... Such as a the door slam, foot steps, etc. Except for the face that the audio quality on the SFX arn't the best. But th esome of them sound really good.... Such as the the dj "s" scratch. It's really cool! I haven't used the usb port when i was recording i used a pc mic. (we didn't have one on hand) I used the keyboard for about a week and I fell in love wit/it! Especially for the sale price of 250$ dollars!

I like the features. Let me explain! I liked the fact that theres a 6 track sequencer! And a USB port I loved the sample songs, they sounded so real! There is 5 types preset Master EQ but i haven't used it, sorry i can't rate them.

It was pretty easy to use! I only used it for a week, so I didn't find out how to record and didn't bother to use the dual processor!

Good Quality! could help you on the road!

Great value for everything in it!
