I have been trying to make an equivalent of the old touch17 ‘displace’ synth but am having trouble…
the mapping is somehow different to t017
the TOPtoCHOP CHOP treats each row of pixels as a separate set of RGBA channels whereas the SOPtoCHOP CHOP creates one long channel for all the points on each x,y,z axis.
to use a TOP to displace points of a Grid SOP, it is necessary to concatenate all the channels made by the TOPtoCHOP CHOP into one channel ready for the channel SOP.
I used a sequence CHOP to do this, but found that it could only sequence separate CHOPS but can not concatenate several channels coming from the one CHOP.
as a temporary measure, I used a select chop to separate out the channels so the sequence CHOP can use them.
surely there’s a better way to handle this? can anyone enlighten me?
otherwise, I have a couple of RFEs to come. 
rod.
