Patch Number 10 - Now that's what I'm talking about!
That thumpy attack will bring synth bass grooves to life - especially in a busy mix......Thank You
Another method is to use a pick. I've done this successfully with the old firmware. It's not exactly a DX7, but it is punchy.
With the additional features ver 3 offers, if for some reason it falls short on punchiness for you, I would definitely try incorporating a pick and some compression.
