Are we any closer to a system fix for the "zombie reverb burst"?

@boyce89976 how is your reverb block set up? The older issue where changing channels would cause the old reverb content from a channel to play has been fixed for awhile now, at least on FM9. I'm able to get really smooth transitions between channels with the reverb block in parallel, mix at 100%, killdry enabled, level the same across channels, and only changing the time and input gain parameters across channels.
After seeing how you set up your reverbs, I've done it the same way with only changing input gain and decay time, but the burst is still happening occasionally for me. One of my friends has an FM9 and is getting the same random reverb burst on changing presets.

Oh ok. I almost never change presets live, I just use the FM9 like a pedalboard, so I haven't been experiencing it.

Do you have the level parameter set the same on all 4 reverb channels across presets, and the same model selected on all 4?

Do you have spillover turned off for reverb and delay in the Setup menu? If so, are you still getting the burst when changing presets?

I only use two channels, both with the Golden Plate. Channel A is set with a 3 second decay, with input gain set to an expression pedal to travel through like 13% to 50%. Channel C is set the same way with a decay of about 7 seconds. I change between the two via a switch on the FC12.

Yes and yes, less frequently since turning spillover off, but it still happens once in 4 songs or so. Some days it doesn't do it at all, others it's more frequent, but for the most part once in 4 songs seems like the average.

ok then I'm not sure I can help with that since I'm not really experiencing it. Can you reproduce it if you have the reverb tails going and switch between presets that have particular channels of the reverb saved? Like try playing for a bit on channel B, switch to channel A, then go to a preset saved with channel B active to see if you can reproduce it. Try other combinations of channels too.

I'll try that. I know I've got several videos with evidence of it, including the one posted above, but finding those instances in the videos from the past couple months would be insanity inducing.

I've been running my pedalboard the last few weeks because of this issue. I would be standing there with my foot hovering over my FC12 preset change button thinking "is this the time it's going to freak out, or not?" :rolleyes: 😆
 
That's weird. Turning spillover off should clear the delay buffers on preset change preventing the issue from happening on preset changes.

Hope you get the reverb thing worked out.

Pedalboard related: For the past 6 months or so I've been running a couple extra pedals with the FM9, just to free up some DSP and have access to the knobs, especially that compressor tone knob which I've been missing since switching to Helix in 2015 lol. Recently put everything on a board so I wouldn't have to keep patching in the pt-nano. Also the always-on transparent Boss drive up front has been huge for me since it lets me set the amps a bit cleaner for the wet fx, and still get a massive "dynamic range" in terms of distortion with volume knob and playing dynamics since the Boss is before the compressor, without losing the benefits of the comp. Loving this setup rn. The extra DSP allows me to run 2 drives, pitch, volume, 2 delays, chorus, trem, reverb, plex verb, 2 amps, 2 cabs, and the enhancer, all at around 77%. RNDIs are very extra but just give some of that Neve juice and kind of function as a patch bay on the right side.

Very cool! First thing I noticed were the RNDI's!
 
I just played for a while and couldn't make it happen. I did get this annoying "pop" that is similar to the reverb burst, but not the same issue. This was going from a Golden Plate reverb at 30% mix then going to 100% mix. At this point I was trying a bunch of different stuff to make it happen, so this may not be helpful.
 
I only use two channels, both with the Golden Plate. Channel A is set with a 3 second decay, with input gain set to an expression pedal to travel through like 13% to 50%. Channel C is set the same way with a decay of about 7 seconds. I change between the two via a switch on the FC12.
First you said it was happening when changing presets. Now you are saying it's happening when changing channels. Which is it?

I'll ask one more time:
1. Post the example presets.
2. Do NOT post a preset bundle.
3. Simplify the preset as much as possible. Remove any blocks that are not relevant. Disconnect any irrelevant modifiers.
4. Unlink all blocks from global blocks.
5. Use factory cabs if possible.
6. Include clear and concise instructions on how to recreate the bug.
7. Indicate the firmware version you are using.

Help me help you.
 
Here my version of what is maybe a similar experience with Delays:

I've also had it happen with Reverbs but could not consistently replicate it.

1/ Spillover and Gapless both off, tempo at 98BPM. FW 29.01
2/ Select DLY1 on grid with Channel A live.
3/ Play a short line and allow DLY1 to repeat it, then hit B on kybd to change DLY1 channel (same effect with FC6).
(Change to channel B has to happen relatively quickly after channel A's repeat)

For me this consistently results in a "zombie" or fragment from channel B. If you wait long enough (probably related to Channel B's delay time) before switching channels it does not happen. If you go from channel B to channel A this does not happen (again, probably because of channel A's short delay time).

I think I have recreated it in this preset. You play on Scene 1. Then while the Reverb is still decaying you switch to Scene 2. Play a bit and then stop playing. After you have stopped playing for a few seconds, switch back to Scene 1 (without playing). Sometimes there will be a reverb burst as if it is finishing some of the reverb tails from when you switched away from Scene 1. I have experienced this in the past far louder than I have been able to recreate in this preset, but hopefully this might point in the right direction. FW 10.00

Edit: This is on an FM3 with Spillover on.

Expensive patch bays! They go between FM9 outputs and FOH?
Correct, and at home they’re patched into my API preamps into the RME. The RNDI-M is $200 so it’s cheaper and smaller than the original because it can’t take speaker level, but it still adds the same subtle harmonic distortion, similar to a mic pre. They aren’t just standard clean DIs.

I admit it’s overkill / extra but this was my “two birds with one stone” solution to needing to save DSP by turning off the mic preamp section in the cab block and relocating the outputs to the top right.
 
Weird thing is I just manually recreated this preset in my AxeIII and have not been able to get it to do the reverb burst.

@boyce89976 Please provide confirmation and answers to Cliff's questions and suggestions☝ in order. He has asked this twice already and is really trying to help here. I want to see this fixed for you as well. I know you are all busy, but this information will help him determine if this is a bug or not. Thank you.
