Today I upgraded my DTX 550K drumset with a new drum synth module the DTX502 instead of the old DTX500.
It offers more zones for some channels, MIDI via USB instead of the outdated 5pol DIN and fresh training songs.

Further I bought another XP70 with soft mesh and another KU100 pedal.

Sorry Alexey still no double bass action, I do use it as a china 😀
