Casio CZ/ VZ/ FZ - Pro Series

I'm new to this list so forgive me if this has been covered before 
but i couldn't find it in the archive.
On a VZ10M/HS2E is it possible to stop the annoying click at the 
start of a note without slowing down the envelope attack? You can 
produce some evil sub bass with this thing but its totally useless as 
every time i trigger the sine wave i get a big click on the front. Is 
this just my machine or do they all do this? Its a major pain in the 
arse. 
Any ideas would be helpful.

I don't think it's a typical behaviour, can't remember having that 
problem with my VZ-1. Are the presets reacting the same way, maybe it 
has to do with the parameters settings...

Just some thoughts of what I'd do ....

I know you don't want slower envelopes-
but do try adding a value of 1-5 for the attack time to see if the 
clicks go away.
The added time may just kill the click (and you might not even notice 
the slower attack).

Also- see if you are modulating something with an Envelope "spike "- 
that could cause the click.
(for instance- a modulating envelope with 0 attack - high level - and 
super fast decay).

are you starting from an initialized patch?

There shouldn't be clicks when notes start because the VZ restarts the 
phases of the waveforms when a voice is triggered.  But if you've got, say, 
a spike somewhere else in the envelope, or a hard attack with a slight 
delay, or an instant-off release, or something like that, then it can 
produce a click because the amplitude goes instantly up or down in the 
middle of the waveform cycle.

slowing the envelope down is the only way to get around clicking.  It 
doesn't mean the envelope has to be slow, just not *instant*.

It sounds to me as if the machine isn't starting the waveform from a 
zero point. Even if i use an initialized patch with only one 
line/module then the sinewave has a click on the front end. Slowing 
the attack down just makes the click slightly quieter but only cuts 
it out completely when the attack is so slow its unusable for bass 
sounds etc.
The same problem is apparent on a lot of the preset sounds (the harp 
sound clicks so much it would be impossible to ever use) but not all 
of them.
Anyone got any idea what could be going on?

This could be a problem with the midi-cable, I heard from ppl. 
getting humm or klicks if they use a midi cable that is grounded on 
both sides...

I just checked my VZ init patch by recording it into soundforge.  There is a 
perceived sort of click sound, but the waveform does start at zero.  You 
could check yours similarly..

You could try using 2 envelope stages for the attack to change the shape of 
it slightly.  I haven't tried this, but making stage 1 faster or slower than 
stage 2 might help, and messing with the level for stage 1 (though too high 
will give the same effect as just using stage 1 for the attack phase, and 
too low will just delay the note- maybe ~70 would be a good place to 
start?)..
