I'm new to midi so what I'm asking may not be doable, at least the way I'm trying to do it.
I have an Oxygen25 keyboard, it has a USB-B output. I want to go from that to a TRS (Type A or B doesn't matter, the board has a crossover) input on a board I built.
I can't find a cable or a resource to build a cable or device to do this.
Since I can't find anything to perform this I'm assuming I'm trying to do something stupid.
What can I do?, can someone point me in the right direction.

The Oxygen25's USB-B port cannot control other devices; it must be connected to a PC, or to a USB-MIDI Host.
To convert MIDI commands to actual sounds, you need some kind of synthesizer. The simplest devices to do this (with a MIDI input and analog outputs) are called MIDI Expanders.
(The "Miditech Pianobox Pro HOST" combines a USB-MIDI host and an expander.)
The simplest solution might be to connect the Oxygen to a PC, and use some software synthesizer.

Clemens,
Thanks for the info.
I understand that the Oxygen can't control, I currently have it hooked to my computer and am running a couple of DAWS and utilities. (Cakewalk, wow steep learning curve, Helm, etc.)
What I had in mind was creating a Windows app to capture the midi messages and use the output to control an OPL2 board I got from Cheerful and output to amp. I want to create this and give it to my grandson.
I also put together a YM3812 Synth card by Tyler Klein and it takes a TRS input and that's what I was wanting the cable for so I could run the keyboard through the Synth card and then out. The Synth card decodes the midi messages, crude but some basic functionality.
Not sure where I'm eventually headed with these projects I have in mind but it's motivated me to learn keyboard. I'm starting raw and I'm old so not sure how much I'll pick up before the last roundup.
I also ordered a Arturia BeatStep thinking maybe I could hook to it somehow.
Being new, the more I learn the more I realize I don't know. So at this point I don't have a real goal just want to learn so you'll probably see a lot of me on this site.
I'm a hobbyist; ex computer programmer and avid electronics dabbler.
Thanks again for the input.
Happy Trails,
Mike
