Problems activating step randomization using midi output in Playbeat

I got to know the plugin a few days ago and I’m just testing it but I think it’s very promising. I have a problem and I don’t know if it’s really a problem or lack of information, I read the manual but I couldn’t fix it.

I use Ableton Live and I’m sending midi information straight to separated drum sample tracks in Ableton, using Playbeat just as a sequencer and the audio is coming from the samples I have in my drum rack in Ableton. I configure the outputs and everything works fine, however when I click on randomize, nothing else works, even with the ‘Lock MIDI Outputs’ function activated.

Hi igordantas,
Can you please share some screenshots of your setup? Also, which version are you using? (VST/VST3/AU) and which is your OS version?
