Yeah... I remember when I had my Eminent 310 Unique organ... nice top plate to put stuff onto
... but these days my studio table has a built in top plate for this, and the space between this and the desktop area beneath it has rackmounting holes... so if such a keyboard were to stand on my desktop, it would simply block all the rack gear behind it
... so that is not for me... I'm actually going to buy a Roland A-49 in the coming week, just to get the keys slimmed down to minimum space requirements on my desktop... and then not look back at any keyboard synth ever again... and just hope that IF DSI makes a sampler synthesizer one day, that it will be rackmountable in a 4U rackspace
... same goes for Quantum.
