I have the same problem with my GR33. To help a little, I added another synth module thru the midi that triggers a little faster. Still doesn't help with lead. I added a VG8EX, and a VGA-7. Now, I'm running thru 4 amps, and using a footswitch to select which, or all to use. By the way, if you're given the choice of a VGA7, or a VG8(88), go with the 88 first, it's more mobile, and has some similarity to synth in its effects (I can VBOW, and play Ian Anderson's flute parts), but the VGA7 has a near perfect sound reproduction, which I don't get running the 8EX thru other amps. BUT (another but) the '7 is limited in patch numbers, altho very easy to edit on the fly.
