the first issue in dealing with say processing vectors in a vex chop is getting more than the current channel into the vop at a time. This can be handled by the use of the chinput() function to get any channel you like in for any pass of the code
chinput(inputNumber, channelN, index)

The next issue is you can only output one channel at a time. So you need to run the same code 3 times to output a vector, one channel at a time. If you made it possible to process N channels at a time and out put the N number of channels per pass this would make it easy to do more chops work in vex and vops

So if you could make a VOP to import a vector or any channel number in any pass this would make it easier to make VEX CHOPs. the second request is to make vex chops able to process and output a user chosen number of channels at a time. eg. process the channels in groups of three then feed in 12 channels representing 4 vectors that get processed in 4 passes.

Is this a good request or not?

ps I would like to go nuts and process 30 odd channels at a time giving me the ability to manipulate rig elements all in vops.
