Hi Lynda,
this happens to all models,new and old.
The effects that are causing this "trouble" are the DSP effects that each voice is using.
You must be aware of this problem and to solve it here is what you can do:
a) You should lift your right hand off the keyboard while switching between the OTS.
(That means you will not keep a sustained note although your musical sense force you to keep your fingers down
)
b) You can disable the dsp effects that causes the problem with the voice edit menu and re-save the style/OTS
c)You can make some changes to the voices that way so the voices of the OTS 1 and the voices of the OTS 2 will use the same dsp effect.
i use a lot the dsp effects on my keyboard and I choose one of these methods.
It depends on the song which one I will choose better and sometimes I forget to raise my fingers on time
I don't like none of these methods but....
The change between two voices without causing troubles in synthi wolrld is called SSS: Seamless Sound Switching.
p.s.
If we have a left voice on with a dsp efect, it could cause the same "trouble" when we are switching to another voice.
