Reapers send pan

Why am i not able to pan reverbs or various plugins using the send pan in Reaper or do i have this wrong,tried post/pre & pre-fx sends got to admit i don't get it at all

Send buses in Reaper are ALSO minimum 2 channels. The 2 channels feed into a pan matrix that either attenuates one or the other channel, NOT a single channel that is then directed to one or the other channel on a stereo bus. So... For example, if you have something panned hard right on a track and make a send to a new track, the signal will only be on the right channel of the send. Pan the send to the left and it's source becomes the silent left channel. This is the one big old clumsy thing to work around in Reaper. Not sure what decisions were made in the coding early on but something is tying Reaper to minimum 2 channel busing. This is the fallout. This also lets you double up the signal inadvertently if you accidentally send something mono down both channels of a bus and then patch it to route both channels at the end. Mind your track channels! :)

Thanks Serr the thing that confuses me is say i want to send a verb OR whatever fx to one side or the other from the fx send using the send pan it doesn't seem to work at all

Hi Manley, panning is most of the time used for Mono Sources. You want to try the mono button on the send and see what happens:). And when hard panning into a Stereo Reverb there is signal on left and right channels. That is how a Reverb works. Greetings from Hamburg

Hi mono button on the send ?

easiest way to reverse pan is to flip the receiving track's width control to -100.

Which Reverb are you using? For a test use the onboard Reverbate. Is that the behaviour your are expecting?

I have an FX chain I can dig up and share. Basically it works like this.. Send to reverb track via channels 1/2, reverb comes out on same side/ or middle stereo etc. depending on the verb just like normal. Send to reverb track via channels 3/4, reverb is a L/R mirror of instrument placement or normal stereo if panned center.

One variation of this I have sometimes used: have two instances of a particular reverb, on a particular setting, on two different sends. The other's output is panned hard right and other hard left. Then, when you send something to this reverb (these reverbs), use two send dials, the other controlling how much of the signal goes into the "left reverb" and the other controlling how much into the "right reverb." If you like, with Reaper's routing you can easily incorporate this into just one send channel, hosting two reverb instances, yeah. But ^ this is one quick and dirty way to do it.
