I would like to add my support for Windows 7 being supported.
I appreciate some people feel that we should ALL throw away perfectly good systems to jump on the latest and greatest, but if a system is designed specifically and only as a DAW workstation, works without a crash, why should we spend considerable amounts of time installing a new O/S which is also bloated with extra apps/services that we don’t want, need or require and can cause unneccessary conflicts.
Some may reply that we therefore shouldn’t jump on the latest version of Halion, (probably not Steinberg’s ideal scenario!!!) but it does offer extra functionality that 5 doesn’t, so there seems some justification.
Jumping on Windows 10 offers very little for a standalone DAW. Disconnected from the internet etc., even the security argument is not so pertinent.
