Just tried 7 or 8 times re-installing but no luck :disappointed_relieved: im sure we’ll figure it out

#84

i’m 99% sure the firmware itself is not the source, so reinstalling it won’t help. this is likely a USB problem or the issue with some grids generating a high pitched noise: 2015 grid noise fix

the two controllers I have tried with it have been a Greyscale 128 grid 2012 and a arturia mini lab

check this thread: Ansible & grid / power issues?

i don’t think im having the same issue that others are describing in that thread, the number of leds doesn’t seem to effect the high pitch tone

when in doubt, power the USB separately.

i’ve ordered more parts for offworld boards but use search for other solutions

ive ordered a usb splitter like the ones above however the sound is also still present with no usb device plugged in at all

#90

whoa, that’s a new one to me.

can you tell us the details of your rack? what power supply? have you seen if it makes noise with no other modules attached?

#91

@tehn its an arturia rack brute 3u, and no nothing outputs from it on its own, but with either my STO or Black Wavetable VCOs it does. I can try and film a short clip of it if that would make things easier

#92

I feel like USB ground loops are becoming more and more of a problem. the Beatstep pro has one that comes with it. I have also come into this problem with a DJ serrate controller that didn’t even need power through USB. Im surprised there are not more products to solve this problem.

hey guys, just tried the adaptor work around that others have tried above however it did not work for me. I still have a high pitch ring outputting from all 4 of my CVs whenever I try and input it into a v/oct input

#94

what oscillator? what output module? have you tried reducing the connected modules to just an output and oscillator? so the power supply is very light on load?

#95

@tehn ive have both a Make Noise STO and an Erica Black Wavetable. So far I have been running either one at a time into a veils VCA because i use that as a mixer, later tonight i could try eliminating that and just outputting directly from the VCOs. Would it be easier for me to PM you with a short video showing whats going on if so I could send you one later tonight.

#96

I am facing high pitched sound (constant pitch independent of oscillator pitch) too with Grid in Ansible. As soon as i detach the usb cable the noise is gone… some frequency settings myke this non audible on Just Friends as Oscillator. But i suppose its just covered.
Its an old grid 64 btw

Is there another thing i can do besides soldering around the grid pcb?

#97

How are you powering the grid? It’s generally a good idea to power it externally (Offworld, Switch etc).

#98

Just via ansible. Fixing myself to any outlet would kind off break the concept of a powerbank driven system. And using the powerbanks usb outs might not keep the grid powered consistent bco of sleep mode

#99

My asible makes noise as more leds light up - I have access to a beatstep-pro usb splitter cable. Is this safe to use with my ansible/grid - or should I look into building an offworld instead?

#100

use the beatstep splitter, it’s fine, as noted elsewhere

@Hlp your power supply isn’t handling the load well, so you’ll need to use a power splitter. you can off course power the grid with a separate powerbank

This is my Power Consumption: 560 mA +12V | 199 mA -12V | 0 mA 5V | Depth: 42 mm |

And this the row power 30
1.5A +12V
0.75A -12V
0.5A +5V

Shouldnt there be enough headroom for the grid 64?

A usb splitter cable like common Y ones? Cool thats an easy solution if the usb port of the bank will keep the grid consistent on.

#102

read the posts above and search the forum, all the information is there re: Y cables.

it’s not about power headroom. it’s about module interaction and noise. eurorack is a pain when it comes to clean power.
