Re: VZ envelope clicking

2003-07-19 by crustypaul

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?
