Past couple of weeks searching for something I recall existed; found it! [http://compasflamenco.com/midi-c-3/midi-usbusb-p-4.html](http://compasflamenco.com/midi-c-3/midi-usbusb-p-4.html) Has anyone used this? any experience? I might give it a try šŸ˜‰ ---

Good find, let me know how you get on if you are the first daring Organellonaut to try it. ---

in fact it seems to look like the iconnectmidi, but cheaper and smaller. I connect my organelle with iconnectmidi2+ on my laptop with 2 usb cable and it works very well with ableton. You just have to set up properly ā€œiconfigā€ software by opening the good gates. ---

@ghostly606 iā€™ll report back; > [@pmd](#): > > I connect my organelle with iconnectmidi2+ Yep, i also have an iconnectmidi2+ and it works, even with some quirks (did use it on the Pianoteq video) but rather leave it for the IPad ā€œdutiesā€. ---

Hi all, I am the developer of the ā€œMIDI USB-USBā€. Some Organelle users bought it to connect it to a DAW on a PC or Mac. [http://compasflamenco.com/midi-c-3/midi-usbusb-p-4.html?language=en](http://compasflamenco.com/midi-c-3/midi-usbusb-p-4.html?language=en) ---

cool, mines arrived too, but no time to look at it till tomorrow power handling/powered hubs, Im a bit confusedā€¦what topology were you trying? usb hosts have to be self powered, so thats okā€¦ so the ā€˜problematic areaā€™ i guess is: ```auto organelle -> usb hub -> midi usb-usb -> mac -> pico/soundplane ``` here, i do use a usb powered hub, so the pico/soundplane draw power thru the hub rather than the organelle. i guess, i could get one of the adapters that allow power to be added directly via usb. (i.e data lines from computer/hub, but power from another psu), but ive heard of audio (ground loop) issues with these. anyway, not a vital thingā€¦ if Ive got the organelle attached to the mac, id probably just connect the eigenharp to the mac too šŸ˜‰ Im glad it works with unpowered hubs though, that was something that i did wonder about. ---

> [@thetechnobear](#): > > what topology were you trying? Without going exhaustive with many topologies, the way I see it is: IF there is ā€œlotsā€ of power (from ā€œgoodā€ powered USB it does not work, all lights get steady on, so this is from either sidesā€¦ @thetechnobear Youā€™ll get time to play with it šŸ˜‰ ---

thanks @SevillaSoft, it arrived safely (and quickly too) and works perfectly. its going to be a really handy thing to have around. @keymanpal , seems to work with both my powered hubs (a manhattan 7 port, and pluggable 10 port) , both when powered and unpowered. using the topology I depicted aboveā€¦ i.e. where the dongle is attached to one outlet of the hub, and then connects to the mac. ---

Hereā€™s a DIY method for connecting two USB hosts together to send/receive USB-MIDI between them. > [@Prost! diy device for connecting 2 midi hosts](https://forum.critterandguitari.com/t/prost-diy-device-for-connecting-2-midi-hosts/5843): > > [Prost!](https://github.com/frederickk/prost) uses Arduino Pro Micros as intermediary to allow Midi host to Midi host communication. Prost! uses 2 [Pro Micro](https://www.sparkfun.com/products/12587) boards (or any compatible board or clone with an [Atmel 32u4 chip](https://www.amazon.com/s?k=32U4&i=electronics&ref=nb_sb_noss_2)) connected serially (TX/RX) in order to pass USBMidi data. Hereā€™s a [demo video](https://www.youtube.com/watch?v=BwLtm9UBdX8) with [Ableton Live](https://www.ableton.com/), an [Organelle](https://www.critterandguitari.com/organelle), and [Norns/Fates](https://llllllll.co/t/fates-a-diy-norns-dac-board-for-raspberry-pi/).

Iā€™ve just ordered a MIDI USB-USB from Sevilla Soft to connect Organelle to Ableton ā€¦ and hopefully be able to send MIDI to both Ableton and Organelle from my MPK mini somehow šŸ¤” probably more than a couple ways to do thatā€¦ Looking forward to tinkering !! ---
