The latter, and contracted as well. The piano has lasted so many centuries precisely because it can stretch the fundamentals and then the harmonics by different amounts. Oddly the larger the piano, the nearer you could get to a non-stretched sound, but then you adjust them to sound like a grand piano should anyway.
I have a large number (1024 per processing element) of modelling elements and you can assign any frequency to them.

thanks. Was the stretch constant (i.e. all harmonics are stretched by eg 10%) or was it progressive (eg higher harmonics are stretched more than lower harmonics)?
Can you do contracted-harmonic synthesis with that as well?
