I liked the fast-responding octave up/down touch pads for quickly finding the correct octave and the pitch bending and modulation controllers that are not mechanical wheels like most controllers. These are touch pads that automatically return to center position for the pitch bend while the modulation stays where you leave it. I liked the mod pad especially for triggering the Leslie speaker on my favorite Hammond B3 plugin.

The eight drum pads, six transport keys, four small faders, and four small knobs can be assigned to send Control Change (:CC) messages using the keyboard itself--no software required.

Complete instructions for programming are at: Here. There are four programmable memory banks for instant recall of personal control preferences.

I have been using the DMK 25 in place of another small 25-Key MIDI controller and I like the feel of the DMK better plus I prefer the four small faders rather than knobs for MIDI volume moves and dialing in filters when playing keyboards. I'm giving a big thumbs up from me on the Donner DMK 25.

It sells for $114 MSRP.
