MOTM

Hi group,
I don't know very much about MIDI, but i'm using a Hammond xk-2(b-3 
clone)and find it to be unsatisfactory. As my controler, it runs into 
an expressionist for the CV, but it seems kind of slugish. It seems 
like there is some sort of delay in the signal.  I have to keep my 
playing very deliberate, pressing the keys down hard and simple. What 
I mean by all that, is that it isn't very sensitive. It sucks as a 
performance instrument used to control my MOTM. Is it the conversion, 
or that I have two independent CVs out? Is there a better keyboard 
for the Expressionist? Or is it to be expected?

Thanks,
Joseph Casbarian
