Hello, I am trying to monitor audio input in real-time with two effects panned independently, and without the unprocessed audio coming through at all.

Is it possible to have one track with the first effect on it, and send only the unaffected audio to a second track where I can add a separate effect?

Or, is there another way to accomplish this?

Thanks!

Hello Dagabond,
Yes, you can pipe the audio between tracks with Send/Return busses. These can be placed anywhere within the fx chain. Drag fx slots to rearrange their order; or right-click a slot, select a position from the “Move” submenu.

Note: The Send fader has no influence on the track’s signal, other than to scale the send signal.

Thanks Levendis!!! I wasn’t aware the busses could be dragged and placed anywhere within the fx chain!

I’ve been playing around with this, and it sort-of works, but I’ve noticed two things.

To have one channel panned L and one panned R, I need to set up a track and TWO sends so that Return 1 and Return 2 can be panned separately. If I pan the parent track hard left and create just one return track, it can’t be panned hard right because the bus is only sending through a left channel. This makes sense, but requires that the parent track’s fader is brought to 0.

The only way to get the return tracks working with the parent track fader at 0 is if an effect is loaded on the parent track so that the Send busses can be dragged below the Gain slider in the effects rack. With no effect added, the busses won’t move. This isn’t a big deal, just a workaround, and the effect can be removed from the parent track after the send busses are moved below the horizontal gain slider.

#2 is more of an actual issue – if I add the pitch effect on a Return track, the latency jumps from 1ms up to 54ms which is expected, BUT the latency on the parent track jumps from 2ms up to 55ms even with no effect on. Is it possible to keep the parent track at 2ms while the effected Return track is at 54?

Thanks!

You can split the stereo signal to two independent channels. In this example:
- i have audio arriving at the track labelled “Send Splitter”. It is processed by an EQ then:
  1. Sent to Send Bus 1; where it is processed by “FX chain 2”.
  2. Processed by “FX chain 1”.
- Notice the Return bus is split into the L and R?!

My apologies, Dagabond.

It seems you’d like to have separate channel information; the left and the right. Which is done by the mono send busses. Once it reaches a return bus track, however, the send is only mapped to one channel. ie. The signal outputs to one speaker. If this is in the Left, panning right crossfades to the Right channel, which has no signal.

If you’d like to make a “mono” output, of that single channel, you have to duplicate it in the other channel and halve the overall output. ie. Have an identical signal for each output; the amplitude halving brings the output to the average level of the original.

I’m only just getting my head around this. My recommendation is to use a stereo tool (fx) for these duties. Podium’s split busses are best considered as a way to independently treat output channels. Not, as the name suggests, to remap mono signals to multiple speakers.

I hope this helps 🙂

Thanks a ton for your help Levendis – much appreciated!!! Something came up and I’m unable to make time to experiment just yet but will definitely go over this in detail at some point and give it a shot.
