Hello Ian Morton
I'm sorry to hear that, however, there are a few things we can do.
For starters, sequences on a patch start automatically, and there are times I want to press play manually later in a song to introduce a part.
=> I suggest you try different Utility settings of transport receive, if transport is off but sync enabled, midi sequence won't start when loaded.
But even then, the play button is extremely unreliable. The amount of pressure to engage it is very fiddly and often either it doesn't start, or it does but the pressure was too much and it stops again.
=> I suggest you go to Utility/Controls and change the touch button sensitivity
And when it does start, it often lags behind the sequence I want to sync it with.
=> When it does start using your finger, it might not start on the clock, which is expected (Sync On )
To start on time, it is better to send play stop messages with something else (controller, DAW, etc..)
Hope that helps
