thanks for your information.
i have just had a reply back from steinberg saying…
Cubase SL 2 projects are definitely compatible with Cubase 6. You just have to take into account, that some of the plugins and VST instruments, e.g. HALionOne, have been improved or changed somehow on Cubase 6, so it may be the case that you will have to change some setting of your old projects to have the exact same results. If you’re using any 3rd party plugins, you should make sure that they are also compatible with Cubase 6, or have them updated as well in case they aren’t
i have 8 years worth of work and about 300 tracks, so am very nervous about doing this!!
i have not bought a new computer yet, i have been put off in the past by the enormity of the task…and fear of losing everything, or at least some essential things!
