Roland TD-27 module produces secondary sounds in Logic Pro

I have the Roland VAD-506 drumkit which has the Roland TD-27 drum module.

I have connected this to my Mac Mini M2 and Logic Pro. I have created an extended drum track to record my drums. Everything is being registered in Logic Pro, but..... I get secondary sounds through logic when hitting the pads. So for instance the Snare gives double snare sounds, a pad connected to AUX gives a tom sounds (i selected that sound) but also gives a cymbal sound??!!

As soon as I unload the file in Logic Pro the so called ghost sounds are gone. Any thoughts?

I suspect you’re hearing the real audio from your kit and the triggered midi sounds from logic. If you just want to hear the midi check for local settings in your module so it’s not sending audio to your output. Then you’re just triggering the midi.

the pad closing the file looks like a controller assignment allocated to that cc.


go into controller assignments and delete that cc or controller.


search for this if you’re still unsure.

How connected?

what is your “extended drum track” instrument/audio?

have you and delay inducing plugins on that project?

My TD-27 is connected through it's SUB port to a USB-C port on my Mac Mini.

In and output device in Logic Pro is the TD-27


The Extended Drum Track is a Midi Software instrument and then I chose "drum Kit" > "Multi-Channel Kits" > "SoCal+" This way I have multi tracks for recording the Drums.


I only have the Drum Track and an empty Audio Track (to insert mp3's into) in my project, nothing else, no plug-ins.

Other odd thing is that when I open Logic Pro the PD-85 PAD connected to AUX-2 gets triggered and I can hear it through my headset. And when my project is loaded and I hit that same PD-85 PAD, Logic Pro wants to close the file??!!!
