There is a bug using the speed button: It only works in the Flash-Mode yet, all other modes are freezing the values, until you change the speed-encoder. Ive reported that bug allready to Simon and it will be fixed within the next update :-)
Haven’t come a across it yet there’s a couple Iv found in there but expected at beta stage but to be fair I would take it out and gig it in the state it is in 10000x better than some beta tests Iv done
