I am with Sinclair. I have several PS1engines that I have upgraded to ERR Command Control and RS. However, I have four PS1 turbines not upgraded because I wish to retain the original sounds. Big Boys, F3s, Alcos, Northerns have RS to update them, it is the unique turbine sounds that have me two blocked. The older TAS and Digital Dynamics could be used to do so, but are now defunct for production. Should someone be able to provide a method to upgrade with retaining the original QSI sounds, there will be, is, an anxious and viable market waiting in the wings.
