For simple keyboard work, I use a Behringer U-Control UMA25S Mini-MIDI Keyboard on a very sturdy swiveling laptop stand next to the computer display . . .

NOTE: In the US at present, Sweetwater and Amazon.com have it discounted at $100 (US). The Jim Dunlop ECB003S A/C power supply is $9 (US), which makes it attractive if you need a 25-key mini-MIDI keyboard and controller. Amazon.com has the Behringer PSU-SB Power Supply General Purpose DC 9V Power Adaptor for $10 (US), but this was not available when I got the Behringer UMA25S, hence the Jim Dunlop power supply. A tilting, adjustable swivel laptop stand costs approximately $50 to $60 (US) at Amazon.com, although occasionally there is one on sale for less, and the swivel stand needs to be very sturdy, which is important . . . ]
Behringer U-Control UMA25S Mini-MIDI Keyboard[
NOTE: The user guide and presets list are available as PDF files in the Downloads section of the following website page; and there are various instruments, effects, hosts, drivers, and so forth forth that also can be downloaded (Mac and Windows versions) . . . ]
U-CONTROL UMA25S Ultra-Slim 25-Key USB/MIDI Controller Keyboard with Audio Interface (Behringer)THOUGHTSThere are several reasons I selected this particular mini-MIDI keyboard . . .
(1) It has full support for all the MIDI CC stuff, and it has a 3-character LED display so you can see the various MIDI CC parameter values as you adjust and set them; and it has assignable rotary MIDI controllers, as well as a set of buttons for MIDI controllers and so forth . . .
(2) It has both USB and standard MIDI ports, and it has controller wheels, as well as configurable velocity, noting I use fixed velocity, which maps to full value with only a small touch, which makes it very easy to play (similar to a touchscreen in some respects) . . .
(3) It can be powered by USB, batteries, or a separate power supply, where the batteries and separate power supply are sold separately, noting that Jim Dunlop makes an inexpensive power supply (Model ECB003US) with the correct specifications and polarity, which is what I use; and the Behringer UMA25S has mounting brackets for a guitar strap, which is interesting . . .
(4) No driver is required on the Mac . . .
(5) It has a very detailed user guide and presets list . . .
(6) It has a full set of line-level audio ports (RCA), MIDI ports, and other interface ports, including expression and sustain pedal ports . . .
(7) It can be used as a MIDI controller for mixers and transports . . .
I also have an Alesis ION Analog Modeling Synthesizer and a KORG Triton Music Workstation (88-Keys), where the Triton has grand piano style keys (weighted and so forth), and all of them do advanced MIDI . . .
I got the Behringer UMA25S primarily to explore the advanced aspects of MIDI, which is easier since most of its physical user interface is focused on providing quick access to all the advanced MIDI stuff, but once I discovered how to set it for fixed velocity I started using it as an input device, since it is easy to play . . .
For the most part, I have no idea what most of the advanced MIDI features, knobs, buttons, and so forth do, but since understanding all of it is a goal my thinking was that even though most of it is a mystery, it would be nice to have all of it, which continues to make sense. It's all there, and the 3-character LED display provides visual conformation that it is doing something, which is helpful in learning how everything works. When there are parameter values and so forth, applications usually show the values, but you need to know where to look, which makes the 3-character LED display so helpful . . .
The very sturdy swiveling laptop stand is fabulous, and as shown in the photograph (
see above) it is in a convenient location at a happy angle, which makes it ergonomic . . .
If you need more keys, then the swivel stand is not practical, but for the 25-key unit it is practical and handy . . .
Lots of FUN!
