Frecjoha - you would be much better having a look on the reFX website paying particular attention to the Vanguard synth. You can download a demo from the link below. A much better way to spend your cash.

The Vanguard replaced their previous JunoX2 synth which was very, very good at reproducing the entire Juno range - and much more. It would not take you very long to reproduce the bass sound that you want on this software - which comes very highly recommended.
