 **[Roland TD-27](https://www.roland.com/uk/products/td-27/)** USB drum sound module 
 
-**Windows**: ✅ Works. Because the local master signal is always routed to the HeadphoneJack it's neccessary to change the signal-routing to hear your jamulus signal on the headphones and not the local signal of the drum modul.

+**Windows**: ✅ Works. The local master signal is always routed to the Headphones. Using JACK is neccessary to change the signal-routing so that you hear your signal on the headphones - not the local signal of the drum module:
 Configuration Changes: On the TD27 open: SYSTEM -> USB-AUDIO: Driver Mode VENDOR
                                          SYSTEM -> OUTPUT -> PAD MAS: remove any pad signal from MASTER(L+R);
                                                              PAD DIR: add desired(all) pad signals to DIRECT(1/2)
                                                              OTHER MAS: remove any signal and add just USB-IN to MASTER(L/R)
-                       In Jamulus set Audio-Device: TD27, Input Channel: Direct(1/2), output Channel: Main(1/2).
-Now the Jamulus signal will be send to the master output jack of the TD27. (You probably need a headphone amplifier to connect you headphones to the master output jack)
