The updated version of the PSR-E403 is coming this month - PSR-E413. It's not top of the line, but still is pretty cool. 100 arps (as opposed to 50 in the 403) Also has a knob for live control of filter, resonance, etc. Even has some decent "live", "cool", and "sweet" voices. Great little board as a companion to your setup... a bang-for-the-buck low-end board for only $230.
