Chameleon Surround version 1.1.0 fixed a bug that prevented reverb profiles from updating correctly while the plug-in processed silence. A room change could therefore involve more than a misplaced automation point.
If the next line arrives with the wrong acoustics, leave the decay controls alone for a moment. Check which slot the session selects, what profile occupies it, and which plug-in version you have. Each check answers a different question.
The appeal of automatic room matching for dialogue is getting a usable acoustic match from recorded sound. Keeping the right match attached to each scene takes another kind of attention. A convincing hallway still sounds wrong over a bedroom close-up.
Start with a small, deliberate check. Find one change that sounds wrong and note the intended profile, the selected slot, and the profile currently loaded there. Avoid adjusting several controls while you listen.
Suppose an apartment scene uses one slot and a stairwell scene uses another. If the automation selects the stairwell slot but its contents have changed, moving the automation point will not restore your earlier choice. You need to inspect the loaded profile.
Version 1.1.0 added two distinct ways to load profiles while working in Automation Mode. The plus button creates a new slot, while the play button lets you compare profiles within the same slot. Choose according to whether you want another entry or a different sound in the existing entry.
During a revision, try treating those as separate decisions. Audition a candidate in the existing slot when you want to compare room sounds, then confirm the final choice before reviewing playback. Create another slot when the timeline needs to address that candidate separately.
A useful test case is a bedroom that appears twice, with a hallway scene between appearances. After changing the bedroom slot's contents, listen to both bedroom passages. Checking only the passage beside your cursor leaves the later use unreviewed.
For a local exception, consider giving the revised passage its own slot and selecting it only over that passage. Keep the original bedroom entry available for the other scene. This makes the scope of your revision explicit instead of leaving it dependent on what you last auditioned.
The distinction is between changing the selected slot and changing what that slot contains. Both can change the sound, but only one requires different slot-index automation.
Set up a short comparison in a copy of the session. Play from before the gap through the first line, then repeat with the intended profile selected manually. Keep the audio, routing, and other settings unchanged so the comparison remains useful.
If manual selection sounds right but timeline playback does not, investigate the switching path before rebuilding the acoustic match. You have narrowed the problem without proving its cause. An incorrect automation value and an older plug-in bug still require different fixes.
Check the installed version against the silence fix introduced in 1.1.0. Avoid describing silence-related failure as normal behavior in current versions, because the documented change specifically corrected it.
For a support report, write down the version, the relevant slot, and whether the failure occurs during the gap or on the following line. Include whether manual selection produces the expected result. Those details make the fault reproducible without sending someone through an entire film.
Keep a separate check for room changes across overlapping dialogue. A correct slot switch does not establish that one shared reverb instance suits a transition where the outgoing scene continues beneath the incoming scene.
Consider a stairwell line carried across a cut into an apartment conversation. You may need the stairwell treatment on the outgoing voice while the apartment voice already uses its own room. Two independently fed instances let you keep those treatments separate during the overlap.
Listen to each voice through its intended return, then play the transition with both active. Confirm that the outgoing phrase retains the room you chose and that the incoming phrase receives its own treatment from the start. If either voice reaches both returns unintentionally, correct the sends before changing either profile.

A slot number does not guarantee the right room
Chameleon Surround lets you load profiles into Automation Mode and select them through the Slot Index Automation parameter. The session can then change rooms along the timeline without requiring a separate plug-in instance for every location.Start with a small, deliberate check.

Silent gaps deserve their own playback check
A pause before a scene can seem like an obvious place to schedule a room change. The historical silence bug makes that exact transition worth testing when troubleshooting an older Chameleon Surround installation.Set up a short comparison in a copy of the session.
