I think that Roland may be using this [Matrix Modulation] as a marketing tool rather than being truthful about it.

I was reading up on the specs behind this. It seems that Matrix Modulation is already present in the Super JV and XP series. If you look in every patch edit menu, you'll see that any three patch parameter can be routed to the three main controller sliders.

What this means is, for example, you could have Reverb, Chorus and Filter sweeps routed to one slider. You cn do this for a total of 3 or 4 controllers (including the C1, C2, Modulation Lever and the 4 data sliders).

So what do you guys think about this?
