The MultiFX module is based on the Spin FV-1 chip which is also used in many other Eurorack effects modules. It features 7 factory effects and 8 effects which were programmed by Robert of tangible waves specifically for the AE Modular system. Please post any questions you may have about this module in this thread. For more information and for purchasing, please follow the link below: www.tangiblewaves.com/store/p51/MULTIFX.html |

OMG.
It sounds awsome.

yeah, Ive got quite a bit of FX, so wasn't interested beforehand, but now im not so sure.. (and some great demos from NightMachines , didn't help my resolve  ) |

So Felix's video was posted on Synthtopia and one of the comment mentioned Keith Barr who not only designed the Spin FV-1 chip but was the founder and chief designer at Alesis! The web archive has this obituary but over at Valhalla DSP there is even an interesting design schema of one of Keith's reverb circuits. |

To anyone having MULTIFX - is your module also noisy as hell?
I really dig the effects, but the noise is kinda killing the fun.
- dry and wet knobs: making shhhh sound when turned,
- nothing plugged in the input: 'reverb' can be heard,
- I have to turn the input level knob below 1/3, otherwise I get digital distortion,
- other issue: it takes about 2sec to change a preset, but it sometimes is a bit more, up to 6sec
Also, Hi everyone!

- dry and wet knobs: making shhhh sound when turned, - I have to turn the input level knob below 1/3, otherwise I get digital distortion, That doesn’t sound right. My wet and dry knobs don’t make a sound and I can have the input level knob turned up higher for most signals too, before clipping starts. The audio of my demo video is recorded directly from the MULTIFX by the way, without any additional processing. |

Thank you for a fast response. Well, I'm happy that it can function better, but sad mine isn't. Guess I'll have to get in touch with Robert later.
Also, it's doesn't even sound like a clipping. I'll try to record some audio, it sounds almost FM-like, with metallic overtones or whatnot.

NightMachines could you check the mono output? I've just checked L/R outputs and there's no noise in knobs, also input leel can be way up there.

The mono output should act the same way as the stereo outputs I'm afraid  But good to know that you can at least use it in stereo until it is replaced. Do you have some electronics experience? You could take the module out and look at its PCB and the connections to the sockets and pots. Maybe you can already see an error there. But of course don't do anything about it until you were in contact with Robert. |

Unfortunately my only experience with electronics is taking apart things and never manage to make them work again. |

Hi rsankowski, Robert has gone on a little holiday last week, but should be back tomorrow. I'm sure he can sort this out. |

Post by rsankowski on Sept 17, 2018 12:40:46 GMT
Yeah, I know, I've already mailed Robert. I didn't want to cause any drama, was just wondering if that's normal behavior (after all, some audio equipment I bought new had similiar problems and the answer often was "it's just what this is").

I exchanged my pre-release FX algorithm chip with the final retail one today, which was super easy. It's just a socketed IC at the back of the module.  I assume this means that some crafty DIYer might be able to burn their own algorithms on such an IC too Maybe one might even be able to create a switchable bank of ICs? Anyway, just happy about the clever and user friendly design again! |

Post by thetechnobear on Sept 27, 2018 10:22:49 GMT
interesting...
so yeah, you should just be able to burn a new eeprom and chuck it in, or even switch in from another fv-1 pedal (assuming its also got a socket eeprom)
or if you want to get into fv-1 dev, then looks like the way to do it is to buy a dev board , SPN1001-DEVB ... so you could develop new algos, then just switch out the eeprom.
(only annoyance is the SpinASM software is windows only, so macOS devs are going to need to use virtual machine)

Just ordered my Multi -FX as part a larger expansion order. One of reasons I wanted it was to produce a stereo output, hope can mess with panning. I love the LO-Fi delay and what it does with the AE Modular so hoping for even more of same sort of fun!

The 4I/O module even has stereo jack TRS sockets. For panning you just need a 2VCA module and feed one VCA the inverted CV of the other, for example. |

its a great module, and its nice to have something in the rack to 'lift' the sound a bit... I particularly like it when just casually patching on my lap/outside with it attached to the headphone module I do sometimes have trouble remembering what the par 1/par 2 knobs do in each mode, but thats the 'issue' with multifunctional modules. (I need to sit down and write it down, that'll probably help commit it to memory) just one thing, perhaps others can comment on... when I switch modes (and powering on?), sometimes it feels like the mode isn't kicking in immediately, almost like i have to twist par1/par2 for something to happen, or perhaps its short delay when you switch modes? its not an issue, which is why Ive not really 'pinned down' the behaviour - just wondering if anyone noticed it, or if its in all my head |

they are? that'll teach me for not reading the specs/manual when I receive the module perhaps robertlanger add the same behaviour to a future revision of the master module.... |

I asked Robert about this and he said that the short delay between switching the modes is normal. |

I really dislike the noise level, it is almost humming when the WET Knob is all the way up  |

Hey, I am having the exact same issues with my MultiFX.
I really dislike the noise level, it is almost humming when the WET Knob is all the way up hmm, I have to say I don't seem to get this...(at this in the way you describe) I have the AE feeding into my Eurorack , so I have to amplify the signal (to about 5-6vpp) to get it to similar levels as the hotter eurorack levels, and I don't notice it there... (Id have expected amplification to make it much more noticeable) thats not to say I cannot 'push it' to find the noise, if I really crank the gain level up, then I can start to hear it - but at that point, other things are happening (distortion) , so its not an issue for me. what I will say is that, its more noticeable if I plug the multifx into the HP Amp module and listen to it there, if you turn the HP amp to about 1/2 you can hear what you describe, but that to me feels like the HP module is over amplifying at that point... as I can listen quite happily at 1/4 turn, and not really hear the noise. but with all that said, none of this is to the level you are describing... it couldn't in any reasonable way be called 'noisey as hell', or killing my fun with it. perhaps talk to Robert, see what he says? as it sounds a bit unusual to me.... do you hear this NightMachines ? perhaps my system is some how masking it, the mixer I use no doubt adds 'colour' ... or the fact i have a cold means I cannot hear it --- as an aside, not related to this issue really: (or your issue in particular) the output level of the AE modular can be a bit low, and when I amplify it - I have to be careful not to hit the noise floor. (*) again, nothing that cannot dealt with a little care , and in fairness something i see/hear with with other instruments (e.g. organelle/axoloti). (my guess is its the low voltage -> low output levels, so kind of expected in this form factor/price point) (*) I became rather over sensitive to noise issues when developing the Belamini module on AEM, because it was polluting the audio signal (see my other thread) and at some point, i was cranking the gain up really high to be able to hear it - forgetting that this was not normal levels. e.g. a real synth patch at this gain level would be either deafening or distorted beyond recognition so Ive tried to reduce my expectations a bit, and accept a bit of noise from things as character (like a tape hiss ) |

Hope he can send me a new one, I am playing a live-show next week and I really wanted to use it. The Deepspace and the Shimmer Reverb just sounds so good... I also made a video of the issue. I had to crank up the volume on the mixer a bit to make it audible for the camera microphone so in normal use it is a bit quieter.

yeah , I don't get that background hum at all... only white noise if I crank up the gain too much. to me, it almost sounds like interference, or something not grounding properly. I assume you don't get this noise if you do the same with other modules in the bottom row... e.g. delay/2att? Id be tempted to try: (which you may have already tried ) a) disconnect multi fx, and replugging it in b) try putting the mulifx in the top row... see if you have the same. (for b, ideally you'd disconnect the lower bus cable... but that probably wont make much difference if you dont) anyway, hopefully Robert can sort you out.... good luck with the gig Mark p.s. the knob noise, hard to say, I can get his but only at higher gain levels...and as you mention your using pretty high gain here to capture the sounds - so cannot really say either way on that one. |

No, my MultiFX seems fine. No excessive noise or distortion and no noisy pots. I guess there was just a bad batch somehow. |
