From the beginning, Yamaha's strategy was to release editors or VST exclusively for "real" instrument owners, and to encourage users without "real" instruments to buy.
The early release of the ESP version of the Montage M was also only for users who owned the "real" Montage M, which was a strategy to drive the purchase of the "real" Montage M.
I'm also using Yamaha's product (vocaloid product),
Due to this incident, I can't use Yamaha's products anymore. This is because I was so disappointed and angry at Yamaha's sales strategy that ignored users who did not own "real" instruments.
