Connecting a table to multiple processors
Is there a built in way to do this or should I use a loop in the on control callback and link the table to each processor one after another?
Yes, this seems to be a reasonable request. Although you might achieve a similar result with global modulators, depending on your use case...
My use case was to put a CC modulator in each sampler to control gain via expression and then have a table on the interface that controls the table of each modulator. After playing with it some more I realised I could just grab the CC value in the script and scale it to the table setting, then forward that to the modulator. This saves me having to specify the modulators in the script too.
