CS-60 Sustain issue

2016-08-10 by sneakyflute@...

Hi,


I'm not certain that the sustain functions are working correctly on my CS-60. It seems as if the notes in Sustain I are being cut off when they are not supposed to be.


Here is one environment where I can hear something odd:


1) I close down the low pass filter and set a long release on the panel (2-3 seconds at least)


2) I then play a chord and then hit a short note on the lowest C (picked only because it will make the oddity more noticeable).


3) I would expect that hitting this lowest C would NOT kill the chord as it is is releasing, since in Sustain I all releases are independent. BUT it DOES kill off the entire chord.


4) Next issue is that if I quickly hit a middle C key while listening to the final moments of the release from the low C (which killed off the other chord), this causes the first hit low C note to suddenly get louder AND the chord that was previously cut off returns (provided the release is still within its originally set time frame/trajectory), and it even sounds like its filter is opening again.


Is this weird behavior, or is this how Sustain I should work?


I should note that the ribbon is currently removed for repair, in case that somehow affects release times (not sure why it would though).


Thanks DT
