Studio One 6 added sends to FX Channels, letting an effected return feed another FX Channel, Bus, Audio, or Instrument destination. Older tutorials often treat an FX return as the end of the road, so their workaround-heavy advice can send you in circles if you use a newer release.
The basic move is simple. Create your first FX Channel, add the delay or other effect, then use its Sends rack to feed a second FX Channel containing the next processor. Your Studio One bus and FX channel routing can stay exactly as it is while the return develops its own downstream path.
This is more flexible than stacking every processor on one return. A send lets the first FX Channel keep feeding its normal output while only part of that effected signal goes somewhere else, which gives you separate control over the first return and the second stage.
You now have three useful controls instead of one long insert chain. The vocal-to-delay send decides how much dry vocal enters the delay, the delay-to-reverb send decides how much of the delay enters the reverb, and the Reverb FX fader controls the final reverberant return. Small changes stay local instead of disturbing the whole path.
Putting the reverb directly after the delay on the same FX Channel behaves differently. With both processors used as wet effects in series, the delay output must pass through the reverb before leaving that return, so you lose the independent clean-delay branch unless the plug-ins themselves provide suitable mix controls.
Series processing itself is old territory in audio design. Series-connected artificial reverberation networks describe successive processing stages where one network supplies the next, but a DAW send adds a useful branch because the earlier return can remain audible separately.
This distinction matters when you build several ambience layers. You might send Delay FX to a short room reverb while its main output continues directly to Main, or send a distorted parallel return into a darker reverb without forcing every bit of distortion through it. The return becomes a source you can branch deliberately.
Studio One also lets an FX Channel send to Audio and Instrument destinations as well as Buses and other FX Channels. Most everyday mixes will use FX-to-FX or FX-to-Bus routing, but the wider destination list is worth knowing when a routing menu looks surprisingly broad.
Keep your effect plug-ins configured for the job their return is doing. Reverb and delay on dedicated FX Channels are normally run fully wet because the dry signal already has its own route, while the send amount and return fader handle the blend. Leaving extra dry signal inside several cascaded returns can duplicate the source and make level changes harder to diagnose.
Pre-fader and post-fader choices also apply to sends created on FX Channels. Post-fader keeps the downstream feed tied to the first return's fader, so lowering Delay FX also reduces how much delay reaches Reverb FX. Pre-fader separates those two levels and can leave the second effect sounding even after the first return fader is pulled down.
Use pre-fader deliberately because it changes the gain relationship between stages. A reverb that seems mysteriously loud after you lower the delay return may simply be receiving a pre-fader feed that never moved. Check the send mode before blaming the plug-ins.
Studio One also prevents routing paths that would create feedback loops, so you cannot freely send a downstream return back into an upstream stage and build an endless circular route. For repeat regeneration, use the delay plug-in's feedback control or another purpose-built internal feedback path instead of trying to close the mixer routing loop.

A send keeps the first effect alive on its own
Consider a vocal delay feeding a reverb. Send the vocal to a Delay FX Channel, then add a send from Delay FX to a Reverb FX Channel. The delay can still reach Main through its regular output while its send supplies a separate amount of delayed signal to the reverb.You now have three useful controls instead of one long insert chain. The vocal-to-delay send decides how much dry vocal enters the delay, the delay-to-reverb send decides how much of the delay enters the reverb, and the Reverb FX fader controls the final reverberant return.

Output routing and send routing solve different problems
Changing an FX Channel's output is not the same move as creating another send. If you change Delay FX's output from Main to a Bus, the entire Delay FX output goes to that Bus as its next destination. A send instead creates an additional path while the existing output remains in place.This distinction matters when you build several ambience layers. You might send Delay FX to a short room reverb while its main output continues directly to Main, or send a distorted parallel return into a darker reverb without forcing every bit of distortion through it.

Cascaded effects need a clean signal path
Naming becomes important once one return starts feeding another. Names such as Vocal Delay, Delay Verb, Drum Crush, and Crush Room tell you what enters each stage and reduce the chance of adjusting the wrong send during automation. A large mixer becomes unreadable quickly when every return is still called FX 1 or FX 2.Pre-fader and post-fader choices also apply to sends created on FX Channels.
