Copied from the FAQ link above:
[[ I’m an existing or old SONAR user and have questions about my old account or subscription or want a refund.
BandLab Technologies did not acquire the operating company of Cakewalk Inc., only the complete set of intellectual property, patents, trademarks and certain assets necessary or related to the entire Cakewalk product suite.
For users of Cakewalk from before 21st February 2018 – please refer to the original Gibson/Cakewalk announcement FAQ ]]
Does this mean that anyone who bought into lifetime updates before 21st Feb 2018 will now have to pay again to get the "BandLab" version when it appears?
