I prefer not to try to guide idiots, they tend to screw up and blame you for giving the wrong instructions :razz:
However, assuming you are not an idiot, I can think of two ways, one is posting a scene file with the set-up. The other way is to explain myself in a way that is actually comprehensible for other people.
Now, assuming you have routed the out 1-8 to card output 25-32
assigned Bus 1-8 to analog 1-8,
and assigned (sent via the bus sends) the eight channels you want to process to bus 1-8, we should be nearly there.
(since you now cant record from 25-32, it would make sense to use these channels for inputs in this instance)
If you are using a send-return effect, you have to send the return of the particular effect to the mix bus that you are using for the original signal if you want a blend (remembering that any signal sent to the effect will be returned, so not a good idea if you use same effect for more than one channel (then it would be better to record dry and record the effect return on a separate track to be blended at mixdown)
If you are using insert effects, you can insert the effect either on the input channel or on the bus channel, in either case, you should now have a processed signal for recording.
