I have see on GSi website a major update for VB3-II with new features, are you planning to release an update with the same features also for the Mojo/Mojo61/Gemini?

The 2023 edition of VB3-II software plugin uses the exact same organ engine as VB3-II v.1.1.1, only some minor functional adjustments have been done to accomodate it into the new plugin, but with zero impact on the sound.
On the other hand, the new VB3-II 2023 Edition can combine both the organ and the rotary speaker engines with those from the old VB3 version 1 (which also powers VB3m), and adds some effects such as the ring modulator, the delay and the limiter.
But if you switch off all effects and compare the sole organ engine V2 from VB3-II v.1.1.1 and VB3-II v.2.0.0 you'll hear the exact same sound. All organ parameters respond the same way.
This is also the reason why an update to the GSi Gemini, Mojo Classic, Mojo desktop or to other hardware instruments based on VB3-II wasn't needed.
VB3-II 2023 Edition offers the same sound of the previous version but in a new package, with some added functionalities and with the ability to combine the sound with that from VB3 v.1.
