Lost count of posts since I began, but after reinstalling USB driver, problem resolved. So now I just use the same dedicated USB cable connected to MODX and Soundmondo has been working fine. Thanks for suggestion.

Sorry, the thread got side-tracked... Let us know how it works.... Any time there is any download and installation, or configuration, or sign in, or unzip, you are bound to have 3 or 4 out of every 10 who will have problems getting it to run. There are over 90,000 sound posts now on Soundmondo - so many are able to get it working. The Internet MIDI is a fairly new area - and as long as you use the same port on your computer each time you connect, the computer should not designate it as a second or third MODX.

Enjoy!

Jason: you were spot on. The driver instance was exactly 2-MODX. Thank you.
Phil “Bad Mister”. Reading your posts from over a dozen years ago you spoke about exponential changes
that challenges you from the early days in engineering. I remain impressed at your ability to stay ahead (or at least current) with these emerging technologies. I can’t remember my grandkids names at times.

Thanks to all.
