Mystery Juno Chorus Noise

Dude, try unplugging the usb cable from your Fantom and see if the noise disappears.

I don't remember this being a thing before and not sure where it's coming from. Anyone else have this problem pop up before?

This behavior still happen since earliers's Firmware versions. I had a Fantom 8 more than two years, and also I got this problem, still with FW version 3.01.

The pattern I detected is, if you're playing a scene where there is a zone that uses this MFX, as soon you trigger a single note in that zone, a noise comes on.

When I change the scene, noise keeps sounding... (I mind could be a "tone remain" bug) and the way the noise goes by, is using a scene where uses the same zone where MFX was set before, and hit a note. It doesn't delve deeper into the subject since it doesn't happen to me frequently and it wasn't something that kept me up at night, but I understand that it's not normal.

I have not tried removing the USB cable. Next time it happens to me, I'll try it.

However, I think it is a software bug.
Cheers,
Flavio

I actually don't have my Fantom plugged into my computer unless I'm ready to record a song in my DAW. My current setup is 100% DAWless with my Fantom being the master keyboard for the rest of my gear. This happens even when the USB cable isn't even plugged in.

Have you tried swapping out cables? Also do you hear this noise in headphones connected to the Fantoms headphone Jack?

Really hope you get it figured out. Lastly try trouble shooting for a ground loop in your set up, which I doubt you have because you would notice a hum vs plain noise I would suppose.

I plug all of my equipment into power conditioners, I highly recommend getting one. Clean your contacts, run out of the balanced xlr outputs.
Try setting the inputs of your audio interface to -10 dbu vs +4 dbu or visa versa.

Good luck. And hopefully a more knowledgeable individual will notice your post and help you solve your issue.

Hi Rahboo,

To clarify, the noise comes from the effect "Juno Chorus Noise", that remains "on" without any note playing or sounding on a zone/tone where this MFX are setted on. It is not related to hearphones or audio cables. This Juno Chours Noise is sounding still when I switch to another scene, until a note on the same zone where this MFX were used on the former scene is played.

Best regards,
Flavio

If the noise comes regardless of the scene, then TFX is most probably ON.

Effects can affect the whole Fantom (TFX blue), selected zones (MAIN changed to IFX and IFX1 or IFX2 in blue), a tone (MFX blue and at least one partial Output Assign set to MFX, not DRY.).

TFX affects the whole Fantom. Think you want to play in a Cathedral and wished all scenes were affected by such stage without having to go adjusting one by one.

IFX affects as many zones in the scene as they are selected to be routed to IFX instead of to MAIN; selectable thanks to a little window at three o'clock of the EQ square below the zone number in the EFFECTS page. Set IFX1 effect, then IFX2 effect if also required and if so choose them to work either in SERIES or in PARALLEL. Their windows in BLUE.

MFX affects the tone as far as and as many active partials (in RED) have their Output Assign set to MFX, not DRY. (Tone edit>PRO>OUTPUT TAB> Output Assign ). If all partials output DRY there is no MFX effect regardless of MFX being seen active (BLUE instead of gray). Yes, you might have selected an effect and also have activated the MFX window but the partials could just be outputting DRY instead of MFX if so were set, either by the tone creator or by you when exploring Fantom...

JUNO-106 Chorus effect (#87 for TFX, IFX and MFX) is provided with a NOISE LEVEL knob that will be heard as far as W in the D/W mix is not 0.

You will get the noise you want from 1 to 127 while also mixing the D/W (DRY/WET) value from 0/100 to 100/1.
At 100% wet, the pitch modulation of a chorus effect sounds like vibrato. To achieve the chorus effect we are to blend the modulated audio with the original, so I think a good D/W mix would be 50/50 to start with.

Almost the same for the astounding Phonograph effect (#91) recently added and available fo MFX (you know then that it is only for the tone), but neither for IFX1 nor for TFX.

After thorough testing along their modes (I, II, I+II, JX I, JX II) I have so far not suffered the mystery described, just enjoyed the results of the effect.

Noise is there as requested, varies with settings and stops as I deactivate the effect or changed zone or scene if the effect was achieved via MFX or IFX while remained along all scenes when achieved via TFX.
