Hi,

Does anyone know to stop the error message that comes up when you launch the Z3ta+ Microhost (32 bit or 64 bit) in Windows 7 64bit?
 
It says:

"midiInOpen()"

"Error opening MIDI deivice".
 
If I try to untick a MIDI device the program can crash. I have updated to Z3ta 2 but I prefer 1's GUI
 
Regards,
 
TD

Are you meaning this error comes up when you run Z3TA+ 2.1 in standalone mode?

I haven't had this error. 

Make sure your MIDI device is on before you start Z3TA+ 2.1 in standalone mode. 

Thanks but I solved this by uninstalling/reinstalling my Midi interface driver.

Glad to hear you got it fixed.
