its not that hard mate, you could do it with whatever synth(i did it on a subtractive).

i would layer a saw wave with more saw wave, pan one hard left, the other one hard right. playing the note on Octave 1, you want the saw oscillators to be on 3 and 4[use both]. very low filter cut off with no resonsance. filter enevelopes, zero attack, less than half decay, middle sustain and release. amp envelope the standard, zero attack, middle decay, full sustain, tiny bit release. equalize after if you need.

thanks for the replay mat but i would be very happy if you choud upload screenshout of those definitions in the VST

thanks again!

hmm, i took a closer ear onto the roger shah bass, not as simple as i first thought. it has some metallic harmonics in the mid, you would need some slight Frequency modulation i believe, so i had to edit the patch, and added overdrive to give some of the lower mids some harmonics.

Im sending you a PM, whether the patch will be sufficient or not, maybe someone else can help you with the exact sound.
