Amazing work !

Outstanding, thanks!

Please fix Chords and Key mode

Please fix the chords. For some reason sometimes samples aren’t playing as chords on the app, only playing as “one” instead of “key” mode. This also occurs on the KO II

Response from developer

Hi this is a hardware setting that needs to change, not a bug in Best Friend. Your sample needs to be in Keys Play Mode otherwise it will be monophonic. You can change it in Best Friend on Pads > Play Mode > Keys or from the hardware SHIFT + SOUND > use - and + to the first setting > turn the X knob until KEY. A Mute/Choke group will also prevent chords

rlly good !!

incredibly polished app with super quick connection from device to phone

Best app ever for KO II

So good, loving it so far

Keep up the awesome work on this! Loving the app so far. Would be really cool if there’s a way to get the keyboard to be multi touch so can play chords, but I know you can still play them with the chord buttons.. so much fun to be had!
