Suggestion: cords per note settings

I've checked out this instrument, and found it pretty easy to emulate in Pianoteq using mainly the una corda "Soft pedal" setting and permanently leaving the una corda pedal on (using the GUI). Either Std or Pro version will work for this.

I agree though that it would be nice to be able to explicitly select the number of strings per note (e.g., have three strings all the way down like e.g. on the V-Piano).

You're absolutely right. The unison width is still in effect when the soft pedal setting is at max. Even on lower notes with two strings per note.

The only reason I figured out that the "Soft pedal" controls una corda is because of the pop-up tooltip when you hover the mouse over it. (And there is no other soft pedal on grands; something I'm not that used to, having grown up mostly with uprights, where soft pedal is a bit of felt between hammers and strings.)

I guess for now the best you can do to emulate a single string per note is to set the unison width to 0 and adjust the soft / una corda pedal setting and/or tweak the hammer hardness.

If you muck around for long enough you can get a sound very similar to the Una Corda instrument (or at least the way it sounds in the demos I was going by). I spent longer on making it than it took me to get bored with the sound and want the proper piano sound back. But I encountered other useful/interesting virtual instruments along the way, like pizzicato strings-like sounds and plucked double bass.

Oddly enough there seems to be no note-by-note adjustment for the soft pedal setting in the Pro version.
