Hi,

I'm trying to shift bunch of channels and can't seem to be able to shift them in time. Having rand($C) in SHIFT chop in ‘scroll offset’ shifts in amplitude; but having it in ‘start’ doesn't seem to do anything. Any ideas?

thanks

Hmmm,

I can swear I did this very thing successfully at some point.

Trying it now, I run into the same issue as you…

yeah same here.. glad to know it's not my memory going..

The Shift CHOP takes a single constant value as the offset for all the channels. It can't shift each channel in the CHOP individually.

$C is the current channel number being processed. The Shift CHOP doesn't use this local value for the reason stated above.

You could use a channel reference, global variable, etc.

I ended up using strech chop and putting rand($C)*10 in both start/end fields and it did the trick. Strange that shift won't let you do that..RFE
