Well, initially, JJ wrote that you only have to pay for the OS once. Everybody thought that you would receive free upgrades for life. But JJ called his latest work JJ OS 2. So you have to cough up $39 more dollars. The kicker is..you have to install the JJ OS 1 before you install version 2. That means for new JJ OS users, the cost of the new OS is $69. This is exactly what Roland did when they updated the Fantom X with sampling tools (I believe this was what they called it). The reality appears that for hardware to survive, paid OS upgrades is the future as it is with software-based products.
