if XS and XF have the same engine this means both will be updated with the same update ? right ? I ask this questions, because i want to be confident about my XS investment for years to come.

I ask u to support my XS investment, by giving me those new XF waveforms as an upgrade for XS RAM MEMORY.

Support me ! and i will support u years to come by buying new synthesizer from u in the future. 

I am glad because i’m not forced to buy a new flagship right now.So now i’m more confident about my XS investment.

Exactly the same thing has happened when i buy the first Virus Ti.Now the second Virus Ti have the same engine, and both are updated with the same update. So i’m glad by making the best investment for years to come.

See the other threads in this main topic. According to YUS, the XS will benefit from the XF development cycle.
