Yamaha CS80

Hi all
Unfortunately no one could give me any datas about CS-80's Chorus/Tremolo
section. Can anyone tell me
1.  can Tremolo work alone from Chorus ?
2. Being  BBD based, what is the delay time and the wet/dry balance ?
3  what is the highest modulation speed?
4.Is there any frequency weaking when Ch is active?
5.For the fake leslie effect which plays the main part between Chorus and
Tremolo ?

Another one on Initial Pitch Bend: is the max bending amount = 1/2 tone at
highest velocity??

Please reply!!
