I just wanted to follow up your problems with the MultiFX. Did you message Robert about it and was he able to help you out?
Hi! I sent a message to Robert, he said that he noticed the noise floor on higher volumes, too. He said that he is going to improve on that and he'll try to fix this in general on the future MultiFX modules. I disconnected mine from the bus cable and reconnected it again, which made the noise floor slightly better (there was probably a grounding problem,too) but you can still hear the noise, just not as loud as before. Guess I have to deal with it, it works pretty well for home recording but not perfectly when playing live because of the higher gain levels on my mixer.
Got my order with my Multifx, everything I hoped for so over the moon. The best bit of the order is the patch wires though - I was using the wire that came with the original Kickstarter machine, the purpose made leads are so much better to use, and don 't fall out as easily!
Most impressed with the MultiFX, not being an electronics wiz it makes me wonder if we pay too much for some boxes which don't sound as good... It fits really well in the AE ethos of reducing the cost on the non-audio areas - hence size, module fronts etc. More please Robert!
I got the MULTIFX not so long ago and when playing around with it today, i notice something weird with the Deepsace effect.
When on the Deepscape mod, a feedback start slowly building but and destroy my sound. It doesn't happen if the feedback knob is set to 0, but the more the knob is turned the faster the feedback start to appear. Is it something normal or I'm missing some knowledge on how to use the MULTIFX?
I haven't notice anything else yet, but I still haven't tried everything yet.

I had a look at TNM's video on the MULTIFX, and apparently, Deepspace is an infinite reverb algorithm. Since these are already set at nearly (if not on) breakthru levels on feedback as part of the algorithm itself, increasing the feedback level means that you're running the feedback above breakthru. This happens with some other infinite reverbs as well; my Lexicon LXP-5 has the same behavior when using its version of an infinite reverb, and when using Zynaptiq's Adaptiverb plugin, that same problem can be experienced in a purely digital environment as well.

Tidied up my synth closet a bit and look what I found! A MultiFX Parameter List! Not sure if that's the final one or from a late preproduction firmware, but it should be pretty close.
Edit: D'oh! I just realized that somebody already put this info in the Wiki. So disregard my post and just rest assured that my closet is tidy now

Yes, I found this list in my emails from last year and put it on the wiki just yesterday! I checked with Robert and it’s correct with the latest firmware.
I seem to have a problem with my MultiFX : it seems that certain effects simply... don't work ? Some work fine, others (deep space, resoverb, ping pong for example) don't seem to do anything at all. The dry signal isn't affected and the wet signal is silent.
Mines playing up - when I power on sometime the select window shows nothing, sometimes it shows multiple selections and sometimes the program knob is unresponsive. Is it best to mail Robert direct regarding any issues?
A little update here - 99% sure it's the usb power supply and ripcord I'm using to power the system - haven't managed to replicate the issues when plugging in with mains power.
MULTIFX is definitely finicky about the power source. It's best used with the original power supply that comes with the master module. If you are having issues, the first place in my opinion to look is the power!
That being said, I wonder if putting it in different places along the power chain has any effect? I guess that's something I'll experiment with the next time I move things around.

That's a good shout - mine is as far away from !aster module as it can be. Also I find that if I keep recycling power eventually it comes on and works.
Not to dredge up old issues, but I also experience an amount of noise from my MutliFX module that is 'killing the fun'. Did anyone ever find a solution to the issue?
To me the noise appears to just be a heightened noise floor that is quite a bit louder than my other modules. This is especially pesky when trying to do multitracked music, as the noise floors will start to add up until everything is a mucky mess.
The third 3rd party manufacturer. Check out my modules! kyaa.co
i’ll just say that what the others say about where this module is on yr bus cable / chain is crucial, i had the same probs when first installing but eventually managed to find a place ( weirdly near the end of a row of 20 ) where it would behave itself... finicketty module this one
From an electrical standpoint, I could see other other modules connected to the same bus affecting functionality, but it seems unlikely that position on the bus would do anything. The cable itself shouldn't be adding any significant resistance, capacitance, or inductance to the signal path, so I don't really get why it would change the behavior of the module. Unless I'm just not understanding something.

There was someone on here who noticed that the bus cables added a significant resistance & voltage drop. I don't Remember the thread name, but this person measured it all thoroughly and the difference between different sides of the racks was def not negligible. So maybe that's it?
My Multifx module doesn't appear to be changing programs, the display changes but not the sound, (it does alter with the knobs a bit). I have tried moving nearer the master module (due to this thread) but has not sorted, anyone else got any ideas?
Huh, that's quite interesting. So the GND gets pulled up the farther it is from the master module?
Aside from pitch tracking implications, would this in some way contribute to noise generation in the MultiFX module?
@maximilius1 reported on discord that he had notes change when plugging in 'nothin' or when plugging in 'gnd/0V' from another module. I think that def is due to the bus connectors resistance.
I do have no idea how the chips in the MultiFX work, so i don't have an idea whether that would be the issue. But if you change the place of a module and it acts differently, I guess that points towards a bus resistance issue? Either that or another neighbouring module was injecting noise?

I'll try that and let you know when I find any solution!
