Sadly, save and then copy the project, save and rename that, lock it ( and maybe backup that project) is the only safe workflow.
Well, the project manager is also quite frightening, but…
Dont forget to store the usbstick in a atomic bunker.
( ok, i could also produce and release that track to vinyl and not only play with one loop, cough…)
All because of pattern autosave.
The feeling of being insecure and as you say afraid keeps me from turning on the a4 more and buying a mk2 or rytm.
Pattern autosave( not being able to disable that) and the great fun sequencer is contrary to eachother for me.
Other answer is dont worry be happy, practice, enjoy the moment.
Not very known seems: you can do a save as of a pattern and his kit if you liked the (plock and other) changes on a pattern+kit you also like and didnt start with a copy of that pattern:
(Kit reload on change in seq config checked)
Go to next empty pattern, paste pattern
Save kit on next empty kit slot and give new name
Dont do it too quick, and if you really think thats the next mozart melody, you have to save, then copy and lock the project.
I wonder also since 5 years if its a tecnical or philosophical reason pattern autosave can not be disabled and this feature seems not heavy requested here
On tr8 I only use and change one pattern and kit and dont care, because its wysiwyg, tuning and decay is anyway not saved, but roland updated it after some months, that pattern can be locked…
