As a user of Cakewalk since 2.0, I'm another who's happy not to have to figure out how to migrate/throw away/relearn to use another product. 30 years of projects is a lot of stuff. Thanks for taking it on.
For myself, doesn't matter to me if you change the name, and charge for the next release. Sure, I paid for lifetime updates - but if you don't make money I'm back to figuring out what my next DAW is. I'd like to continue with the product until I die (figure 25 years) so make sure your market strategy is good for that long
Mix and match the products code, implement forward thinking features, your future user base will expect it. But please keep the current core of a studio capable DAW intact in some version of the future product.
Lastly, because some of us feel this way, I'll pay $200 for a all new whiz bang 'new and improved'. I'll pay $400 for a rock solid product with the feature set as it is now.
PS. I'll give an extra $100 for a VST version of the TTS1. Very utilitarian plugin, but still something unique to Sonar I have a use for. Currently crashes Sonar constantly. If Roland can charge $150 for a software Sound Canvas...just sayin'
