LMMS connecting issue


I use mac latest version of LMMS, but I don’t have the choice of Apple midi interface in the midi interface setting section. When I edit my piano to enable midi input there is no keyboard icon for me to choose IAC bus. Therefore, I can’t connect my instrument to LMMS. Can anyone help to solve this problem?


Please use the ‘Beta’ Version of LMMS for mac. The ‘Stable’ Release doesn’t yet support the Mac IAC Bus. It was added to the beta version in December of 2016.


after downloading the LMMS I tried to open it but it says “LMMS” can’t be opened because it is from an unidentified developer.
