Short answer: yes, to make a mono send, only wire the L channel.ttoz wrote:mono sends??
the same as above but on mono signals? same principle applies but just use left in and out right? or should I just use stereo sends on mono sounds?
Slightly longer answer: the return, however, can be either mono on stereo, depending on what you want. For example, the "stereo echoes" reverb preset on the RV7 isn't going to sound very stereo if the return is wired in mono!
Even longer answer: before deciding if your send should be mono or stereo, consider what source material you're sending it. If you're sending a drumkit from Redrum that's panned into various places across the stereo field, a reverb might sound off if you have wired the send as a mono send (and/or a mono return). On the other hand, if your source material is a subtractor, which is mono anyway, wiring the send as a stereo send is a waste of processing power and will actually (very slightly) slow Reason down.
Final note: All of the above is what you'd *normally* do. But half the creative fun to be had with Reason comes from the "what-if" experimentation it allows. So don't be afraid to come up with the weirdest routings and effect chains your brain can come up with (deliberately or accidentally)!
For example;
* what if you wired two different reverbs to the L and R channels of a send, and they had different settings?
* what if instead of sending an RV7 "stereo echoes" reverb back to the mixer, you sent to another reverb first, and then back to the mixer? (you can get some killer long ambient reverb this way, just keep all the wiring stereo *except* the first send).
And so on. By all means learn how things are normally done, but after that, the only rule is that there are no rules!
