Joining last year's popular microKey 37 come new 25- and 61--note flavours for 2012. The 37 was an ideal quick-fix portable keyboard, but its one major shortcoming was that it was too power-hungry to be used solo with an iPad. This is something Korg has fixed for the new 25 and even the sizey, not-very-micro 61.

Both now - with the use of an appropriate interface - can be powered from a ’Pad.

The 61 is pretty lengthy and shares the same curved back panel stylings as the 37 original. Keyboard action is identical and playing with two hands on a bus is now possible. Let's just hope Korg makes some kind of special carry case to slip this thin, ever so slightly flexible, ’wand’ into.

Both the 25 and the 61 offer the same two additional USB ports that are ideal for additional dongles and - great news - the 61 comes complete with Korg's brilliant (but slightly under-appreciated) Legacy collections, both Analogue and Digital.

Highlight of the 25, however, is its new joystick controller, a small thumb stick nubbin with a short throw and a soft foam bed and springy support. There's are the familiar octave switch buttons, but pitch and mod are now on the tiny stick, freeing up room for an arpeggiator button with selectable patterns, and a sustain button, too.
