I can't see anything about portamento in the piano and organ programs. Is it eliminated in those programs because it isn't common to use porta on piano related sounds?

The Kronos has 9 different engines, each of which supports a host of features relevant to the instrument that's being modeled. For example, SGX2, the piano engine, supports string resonance and piano lid position. It doesn't support portamento because this is not a function relevant to piano playing. This helps keep CPU overhead down and polyphony up. If you want to use portamento on a piano sound you could use any of the piano sounds that are in the HD1 engine.

Portamento is a monophonic effect.. gliding from one note to the next..

Piano and Organ are by nature Polyphonic instruments, and so a simple polyphonic feature would not work..

Portamento is used for monophonic synth sounds, but also very usefull for Brass, saxes and such...

Portamento isn't necessarily only for monophonic sounds. Even a vintage synth like the Juno 106 has polyphonic portamento and HD1 does too though it's kinda fake in implementation.

I'm not at my Kronos at the moment, but I don't think pitch bend is available either. As an earlier poster explained, it's not something you could ever do with a piano, so fair enough. There's always a workaround, though - resampling, for example.

Of course portamento is available for piano sounds - it's a Kronos, after all!

It's just not available in the SGX1 Piano Engine specifically.

You can apply portamento to any piano sample, including those used in the SGX1 engine, by using the HD1 engine. The tradeoff is slightly reduced polyphony and some of the SGX sound-shaping options.

Since ultimate realism is apparently not the aim you could just use any piano already in HD1. Saves you time trying to replicate a double 8 layers of SGX2 pianos.
