Squeak ..a whole post without any colorful language

Squeak , when you layer piano and strings, and use a hold pedal..How does the drop out after polyphony runs out,,react..Does it just shut off like the early PSR's or drop off very noticeable like the PSR9000 did/does?
Or has it been improved enough with allocation of main voices[like the other guy.

]...?????
Squeak is there an audio input?
