I guess I will have to resign myself to having a second class action, merely as good as the T4's... LOL
For all the fuss made about aftertouch, I find I hardly ever use it. I find that programming a delayed vibrato into the voice itself works well, and then I don't have the accidental triggering of it by generally strong playing (my LH is basically as strong as my RH). Roland's lost the ability to modulate LFO speed by aftertouch with the G1000, and since then, I have made little use of it.
So, other than aftertouch, I ALREADY have an action easily the equal of the T4's, only at $2500 less. Not too shabby.
An arranger is just a tool. What matters is what you build with it..!
