Hi, Ben, Thanks for pointing out the transpose problem. I followed http://www.ewiusb.com/sysex_page2 and changed it and now the device started to work!
The issue of initial volume can be fixed by setting the velocity to some non-dynamic value. Here is the cmd. Hope it is useful to anyone runs into the same problem. amidi -p hw:2,0,0 -S "F0 47 7F 6D 02 00 0B 00 00 40 44 11 00 00 7F 00 7C 7D F7" sadly, the volume does not change when blowing harder or more gently. But even if setting to 00 (dynamic) it will not change. Cheers, F On Sun, Sep 17, 2017 at 8:02 AM, Freeman LIU <freemanliu2...@gmail.com> wrote: > Hi, Tom, > > Thanks for your analysis.

Google photo is becoming more and more useful. Chromecast is just useful. Let alone Google home.
