We’ve had a number of people inquire about upgrading their Korg Trinity keyboards to the newer Trinity V3 version.
Version 3 operating system for the Trinity can be downloaded at their Web site. It also comes with the MOSStri update, which is basically the Z1 synthesizer on a card. If your Trinity currently has the SoloTri (Prophecy on a card) you will need to replace it with the new MOSStri, which retails for $700. V3 is not compatible with the SoloTri.
