One of the biggest problems with being away from home for months at a time is not being able to play music. I don't mean listen. I mean compose, improvise and perform.
So tonight I ordered an M-Audio 88-Note MIDI Controller from Amazon (Sam Ash, actually) which I can keep here in the US.
The cost? $250. One-tenth the cost of the Roland A-90EX 88-Note MIDI Controller in my studio at home.
I'm not expecting the touch to be anything like the Roland or my Korg Triton LE 88. But when the alternative is not being able to play anything for months at a time, I'm willing to cope :-)
I don't know why I didn't do this two months ago.
