I remember when the Keylab 88 first came out, the plan was to couple the first 1,000 Keylab 88s with licenses for Pianoteq Stage (which I appreciate, I love Pianoteq).
Just speculating here, but was Piano V developed so that it would be an enticement to eventually sell more Keylab 88s? It would be a good plan if so because the Keylab 88s main competition, the Akai MPK88, doesn't have any such thing so it could help Arturia.
