Download the trial first – it can be installed parallel to the existing C6. That way you have a month to work through the issues before making the final decision.
Will my projects be compatible after the switch?
Quick answer, yes, you can load C6 .cpr files directly in C10; longer answer, complex projects may need some adaptation, so make backup copies of all your projects (ideally you would have been doing this anyway). Remember that C10 is 64-bit only now, so if you have a project with 32-bit VSTs, these will need some form of remediation. Many people here will be able to help and advise with any specific issues.
Having made backups of your C6 projects, I would suggest the following:
– load the project (e.g. “hitsong.cpr”) in C6 and save it under a new name, e.g. “hitsong-C6.cpr”
– load “hitsong-C6.cpr” in C10 and immediately save it as “hitsong-C10.cpr”
– in C10, work only on "hitsong-C10.cpr from that point on
This way, you can still revert to the original project in C6.
Can I transfer my hardware maps (program selection) from version 6?
If you mean patch lists, yes, these are text files that just need to be copied into your settings, get back here when you get to that point, start a new topic and we can go through the details.
Does jbridge work still or do I have to forget 32 bits programs?
Apparently yes, although I don’t use it myself. Personally I strongly recommend moving to a pure 64-bit-only environment for the sake of stability.
Steinberg has been talking to change the authorization process for years allowing to use license on two computers. Has this been implemented?
No, but of course you can move the USB-eLicenser between computers.
Will 32 gb ram be enough?
Unfortunately this is the “how long is a piece of string” question. If you had enough RAM in C6, then you have enough RAM in C10. 8GB works, 16GB is good, 32GB is better, 64GB might be a waste, unless you know you’re going to use it.
