I got an M Audio Oxygen 25 key controller,this is fine for me,as I have no room,but as mentioned by RXTX the Akai is very good (wish I had one TBH, and the cash of course
But Ive managed ok for quite some time with a small keyboard,lol. ,
Also, worth a mention is these midi controllers I have bought
My Akai LPD8 for its drum pads,and knobs!! I like this a lot!!
But I don't do drums on it.Everything (or nearly everything else) Ha,ha ,FX ,mapping of DrOcotrex to the pads etc
I also have got a Korg PadKontrol and NanoKontrol 2 all of them come in very handy ,esp when using this to control your SSL mixer sliders and stuff,ha,ha
