Haven’t received it yet, but I just bought a Samson Graphite 25.
2 octaves, 8 midi knobs, pitch/mod, velocity+aftertouch, and a few midi drum pads.
It’s been difficult to find a currently offered small midi keyboard product with a true midi output jack, and not just USB.
Alesis QX25 is a similar product.

At minimum, I just wanted more than a single octave for entering notes into the sequencer, and velocity. Things like aftertouch, and midi encoders are a bonus.

My plan is to assign the 8 midi encoders to various filters and breath, as to have access to all of those parameters while still in Performance mode.
Maybe even set the 4 pads up as a single parameter “scene” of sorts, in the vein of the Analog Rytm.

Ultimately, I’m hoping to get more control (from a programmer’s performance perspective, and not of a keyboard player) as well as more portability than I would out of an AK-37.
I think either the QX25 or Graphite 25 can grant that, so long as you’re okay with 25 keys instead of 37+.
I can cope with the lack of individual outs. It will just take a little more time to program things to get the mix right. Fortunately there are 2 filters per voice, and I often use the multimode filter as an EQ of sorts.
