Welcome. Just to make sure you mean this tool(?) → Custom Pattern Navigation | Renoise
I think the person who wrote the tool is @vvoois (Personally if it was me I’d modify the tool to try and get it to work under 3.2 and go from there if you want to try and get in contact etc…)
P.S. taktik could of modified slightly the behaviour of renoise.SongPos in 3.2 possibly due to this thread → renoise.Transport.song_length.line off by one but that’s just some quick speculation on my part if that is now causing error in the tool.
