…commitment of the Halion 6 development team after it is released and before Halion 7 is released?
Halion 5 was a tragic low when it comes to updates and/or product specialist involvement. Some early release bugs are even still present in Halion 5. One update (5.1.0) and one hotfix (5.1.1) in almost 4 years, really is too lean for a €349 costing piece of software.
I like the Steinberg instruments, but the previous lack of dedication and commitment to make a good product even better after the release, has been quite a let-down in general with the Halion line.
With Halion 6 it looks like you want to facilitate a platform for sound designers to develop content, maintaining the framework for that content is particularly important.
