Hello again, I just tried out your tool, the MidiTools 1.3.0 and did a test series. First thing i saw under the view "input messages" is that actually the keyboard sends $FE and $F8 active sensing signals in idle state. I put the keyboard in "Multi Mode" and "RC Mode" for the test. In addition i tested with pressing and releasing a key at a high and at a low frequency. The test results are as follows: ************************************************ SETUP1 - keyboard midi-out -> soundcard midi-in: ************************************************ -Multi Mode: --no key pressed: ---> $FE signals only, 4 per sec. --keypressed/keyreleased: ---> $FE signals correctly interleaved with keypressed/keyreleased signals -RC Mode: --no key pressed: ---> 1x $FE, 7x $F8, 1x $FE, 6 x $F8 signals then loop, 32 signals in total per sec. --keypressed/keyreleased: ---> $FE and $F8 signals correctly interleaved with keypressed/keyreleased signals ********************************************** SETUP 2 - BCN44 midi-out -> soundcard midi-in: ********************************************** ->no active sensing signals at all, only knob turning messages (pitch/mod). *************************************************************** SETUP 3 - keyboard midi-out -> BCN44 midi in, BCN44 midi out -> soundcard midi-in: *************************************************************** -Multi Mode: --no key pressed: ---> same as in setup 1 --keypressed/keyreleased with a high frequency: ---> only keypressed and keyreleased signals, no active sensing signals at all --keypressed/keyreleased with a low frequency: ---> no signals received at all for some time, then a bunch of keypressed and keyreleased signals in one rush followed by active sensing signals -RC Mode: --no key pressed: ---> same as in setup 1 --keypressed/keyreleased with a high frequency: ---> only active sensing signals, no keypressed or keyreleased signals at all --keypressed/keyreleased with a low frequency: ---> active sensing signals correctly interleaved with keypressed and keyreleased signals So this was it what i observed so far. The LED of the soundcard always flashes at the same frequency of the signals received. Seems as if the BCN44 has buffering problems? Maybe its overloaded and i need to put it into a different state. By the way: is there any way to reset the entire thing to default state? From reading the (somewhat confusing) manual i couldn't find out : /. Thanks, electron8000
