UPDATED 24th March 2013 - FX box position can now be used to modulate FX - This is massively fun BTW!Download V3 below [in the comments]
I was teaching the other day and one of my students had this patch with lots of effects in it. They were all routed to a central matrix~ object. It was really powerful but let down by the fact that controlling the matrix~ can be quite confusing esp when performing live. Personally I don't like having to think in rows and columns when I just want to put the delay after the gate instead of before it.
Today I made a first step towards solving this problem and Mr Matrix was born, have a look at the attached patch and hopefully it will be pretty self explanatory. Basically you define your FX blocks, they appear in a GUI and you can drag them around to re-order or remove them from the signal chain. I've included some very basic FX for you to demo but the intention is you'll fill up Mr Matrix with your own creations.
Have fun and let me know how you get on....
