You know, you might actually like the M-Audio Keystations. They are inexpensive to try and are the entry level ones a lot of people start on. they are not bad at all and are simply basic keyboard controllers. You can get them in 25, 49, 61, and 88 key variants.
Another inexpensive choice would be something like the Alesis Q49.
Korg makes a ton of entry level ones in the Microkey range but they have mini-keys. I’ve owned one, it’s a good product, but I hate mini-keys.
The Roland GO is a nice basic option if you want more piano/keys and it includes midi too. The nice thing is that you can play keys with or without your computer. For keyboards with more keys I personally prefer a piano or synth. For only computer related stuff I use my Arturia Keystep which is a mini midi controller.

Yep there’s a bunch of digital pianos in this price range, good example. There’s also the Korg D1.
I have had this one for a long time, its a really great digital piano.
Never really used it for any MIDI stuff as I had no idea what I was doing at the time with it for MIDI, I was learning piano at the time.
When bass came along, it pushed this guy out of the music room and into the kids playroom (aka future music room).
My daughter learned piano on it, and it did a stint in the nanny’s bedroom who played. I’d love to get back into piano playing, but…sax, bass, DAW, video editing, yard work, work work, family, sleep, eating, family time etc….you know. It’s a great piano, just BIG.
Now that I have the Kali monitors it would sound great through those…just no room.
Nice!
The nice thing about the digital pianos, for piano players, is the key feel.
I happen to prefer the lighter feel common on synths but totally get why piano players want that weighted key feel.
That’s one thing I really DO like about the M-Audio Oxygen: the weighted keys. It does have a very nice feel when playing.
In all honesty, I wouldn’t mind the presence of all those gadgets if I could PERMANENTLY set them up do do something. I did manage to figure out how to train some of them in Reaper and on the piano app, but later discovered I have to redo the training process every time I start a new project. That sucks!
You can permanently map controls in Reaper. There’s a couple methods posted above in this thread. There’s also things like this using Actions.
Here’s a good video for that.
I tried that one you suggested, but my Piano One app won’t allow me to do it (that function is greyed out). Probably because I have the free one. I suppose if I purchase it I might be able to do it.
I’ll check it out, but I gotta say, this MIDI stuff really makes my head spin…
Why did I start reading this thread? My finger is poised to buy one of these

Get the 49 key. You won’t regret it
Not enough desk space (I already have my DAI and Zoom sitting on my desktop. I want to use it in front of my Imac. Not on a separate stand.
Bigger desk LOL
Pam is spot on…I have the KeyLab 49 Essentials, its;'s worth the extra money for it. The mini is great if you are going to be traveling and want to throw it in a backpack.
Think in 3 dimensions.
Can you add a monitor stand and put your DAI and zoom tucked under a bit or on the stand too to free up room?
Your desk isn’t full unless things on it touch the ceiling.
Oh yeah, didn’t see the picgture before…prop that mac up 4", get a swing arm for a monitor and put a music stand on it.
You could put a bigger keyboard and a drumset on there dude!
Agreed.
Where is the keyboard in the picture of your setup @John_E
Two deal breakers for me on the controller @Barney is looking at would be
1 - The mini keys
2 - Only a 2 octave range (yes you can change the range with the octave + and - keys but that could be cumbersome)
Again we are dealing with personal preferences and a lot depends on what you are going to use the keyboard controller for.
If you can live with mini keys and a two octave range go for it.
You will know within a day or two if you are happy with your choice.
Welcome to the Midi rabbit hole 
In the other room, its a full size yammy digial piano.
My first step in conquering the kids playroom!
I do plan on a video speed editor hopefully for Christmas this year.
That explains why it’s not on your desk 
Off topic, but I have to say I still can’t take my eyes off your pedal board setup.
If you took the value of all those pedals and bought a full blown multi effects processor unit I wonder what the price difference would be. Not to mention the savings in real estate.
