Hiya folks! I’m trying to troubleshoot something, so I figured to see if you all have any ideas ( @thetechnobear it seems like you are an expert with both Organelle and Midihub, so maybe you and @Giedrius and others may have some pointers). I’m experiencing weird noise issues when bus-powering Midi…

What sound sources are affected? Is it Organelle itself generating the audio?

Hi @Giedrius … thanks for responding! Good question … I here the noise even when everything is muted, no instruments are generating sounds or are connected, and pedals are physically bypassed (via the Switchblade 8F matrix switcher, true bypasses, etc). I’ve plugged and unplugged as many different …

Hi @Giedrius , I tried a bunch more things, and found a couple things that impact the noise distinctly! One being that the issue with the noise happens if Midihub is bus powered from my Organelle and also when it’s bus powered from my computer (but the noise doesn’t happen if Midihub is powered by …

[image] Joe_Novelli: Disaster Area’s page mentions that pin 2 of the midi controller’s output needs to be earthed / grounded for the CBA adapter cable to work properly. Could this have anything to do with it? Midihub’s outputs have the pin 2 grounded. I suspect it might be something special …

Though with all my other chase bliss pedals, I convert midi to their specifications using either a disaster area designs Midibox or simply the same kind of midi plug to trs ring positive plug I’m using with Midihub, and they’ve never caused the same issue. That could w…

[image] Giedrius: but there was a thread here some time ago on WIDI master, maybe there’s some useful info: MidiHub and WiDi Master in case it’s of interest, @Joe_Novelli , @deebee posted a comprehensive solution about setting up a more complex WIDI setup with Midihub (starting about here fo…

Thanks @resonotter and @Giedrius ! I’ll look more into the widi stuff, especially for simplifying the ipad/iphone connection. And @Giedrius i talked with Daniel at Chase Bliss and you’re right about the likely reason for the noise … they always recommend the midibox in between because both the chas…

Usually the opto-isolation is on the input side of the receiving device, powered by the receiving device itself. I think it’d be best to consult with Chase Bliss for the minimal electronic solution you could employ to avoid the noise issues, they might be able to share some insight on how their MIDI…
