I agree with 7x7 in that the Emu modules (Vintage or Classic Keys) are true bargains with very good Mellotron sounds. I still have my Classic Key module and tend to layer it with other bds. (JD-990 with Vintage rom, K2500rs and the Korg Radias) to name a few. I used to own a Mellotron and would never want one again, for me these roms are just fine. If you see Genesis live you will hear Tony playing a JD-990 w Vintage rom for the Mellotron sounds.
