I have the v2 bundle and have been very impressed and gotten so much use out of it. They are incredibly fun to play with my Roli Seaboard Block. Really looking forward to the improvements in v3.
The upgrade from v2 to v3 is $30 per instrument or $90 to upgrade the bundle.
The individual instruments are $120 and the bundle is $360. Purchasing now means you will get a free upgrade to v3 (which will not replace, but run alongside v2).
