I just experienced this again. For some reason despite BMP was 60 the tick was twice faster, if not more, for a while, later it went down to 60. I dont know why this might be happening. It just happens sometimes. I think at some point it was the opposite, it went down to 30bpm or so.
Hi Enrike,
This sounds like a bug. If you can get me a patch that replicates it reliably I'll file an issue on GitHub.
I will try but its going to be difficult because it just happens very randomly and I dont see any pattern at all to guess where it might come from. Just in case it is an initialization issue with the BPM argument in the sync-jams object, I am passing a set-state /BPM 60 message on loadbang after a 1 sec delay. So far I have not seen it again but it pops very very randomly so it might be coming from anywhere else.
