Strange behaviours on preset 8 bank 1 of the Crumar Seven - physical modeled grand piano

Crumar Seven's main focus is the electric piano sound, most of the sounds are based on a real-time synthesis models, various types of synthesis specifically engineered to thoroughly reproduce a particular type of sound. But you can find also a lot of sampled sounds, most of them are the counterpart of the physical modeled ones... in this way you can touch and feel the difference between the two technologies.

There's also a physical model of a grand piano...like it is explained in the user manual on page 11 and on page 34, this has to be consider an experimental sound.

From page 34: "It's worth noticing that this sound engine is still in its experimental phase and should not be considered a key feature of the Crumar Seven. We recognize that, despite its editing capabilities, it may not sound 100% realistic and is not problem free. If you need to play a realistic acoustic piano, please select one of the sampled instruments."
