I’m using Magix Maker Premium edition, every time I’m drawing patterns in Piano Roll using a plug in my app freeze and then crashes it does it every single time!
I assume this is the plugin? If so, I can see nothing that would suggest it is in any way incompatible with MM. Unfortunately, it appears there is no Free Trial and I am not prepared to pay $50 simply to ascertain whether a plugin is compatible!!
However, can you be a little more explicit about how, exactly, you are drawing the notes on the piano roll? The usual method is to click on individual notes, one at a time, to create the wanted "melody". It rather sounds as if you are dragging the cursor across the notes, rather than clicking one at a time, which might well lead to a "data overflow", and hence the crash.
Than you for your reply that is the correctness plug in, all set up it’s just the Piano roll, when It freezes there is a little arrow as the cursor I can only assume this is what you mean by drawing accords?
