thanks for getting back to me.

yes this is the way i'm setting it up. I was just asking about the "midi" option instead of "audio". As my laptop seems to struggle to play more than one audio channel at a time. I've been told this is due to the speed of the hard drive being too low. Therefore i'm limited to the amount of audio channels i can run, and mainly use all midi now.

I'm actually getting the vocoder to work but find the presets aren't giving that classic vocoder sound (if you get what i mean). Even having spent hours playing arond i still can get anything near that classic sound, but i've found some interesting variations.

thanks for you help
