Behringer Crave is a good choice under $400. Further you can check this for good options.

I personally use Behringer Crave and its good. But The “note” buttons are not smooth but hard-clickable... on live a bit annoying... here you are forced to hide the hard click sound that every key press produces mentally.
Otherwise, the device is quite valuable from the haptics... deck and front/back made of metal... feels good so far.
However, the technical and audiotechnical characteristics are the main reason why you buy this device from Behringer.
Okay for the price too.... but the click sounds when operating the buttons... close to the microswitch sound of old joysticks - only unfortunately with higher resistance... on sound devices like this, the sounds should only come from the device and not quasi-mechanical from operating the buttons.
