Hi, can you briefly explain to me:

What are agraffes, and what are they used for?

The Triplex scale (Schimmel pianos), what are the differences compared to the duplex scale? Do you happen to have a photo of the Triplex scale, so I can understand better?

What is the Capo d'Astro?

Thank you

Denis

I am not up to date on the triplex scale. Aggraffes are used as nut/capo for the strings in the middle register. Capo d'Astro is the bar that serves as a nut in the high and super-high registers

I think that by triplex they mean the front resonators. But I don't believe it is exclusive to Schimmel.
