This topic is just to show explanatory diagrams for two patches on patchstorage
If you’re a regular reader you’ll have already seen them here and here.
Both use loopback techniques, so if this is being read after the next major firmware update, hopefully they are both redundant!
EDIT: If you have a 8 (or fewer) states and want to cycle through them up and down, you might want to try adapting the patch here first (it needs no loopback)
There’s also a simpler patch further up the thread that can handle up to 16 states uni-directionally.
