I'm afraid that this trouble isn't solved yet
Only solution for today is to use CV gate in.
If you don't have any gear with CV gate output you can use a sound sample of trigger (i've recorded mine from roland tr-727). If you put this sample into a sequencer/DAW and asiggn it to another output than stereo you will be able to trigger your mircobrute sequencer.
E.g. I use MPC2500 for this. The sample is triggered through assignable output, so it can't be heared in stereo output of an MPC.
I've attached CV trigger sample to this post so you can download it.
BE CAREFUL because playback of the sample can damage your speakers!
Cheers!
