Recently this electric drum kit arrived here at the Hallgeir house of techno music devices. It is a couple of years old, I believe, and based on the Roland TD-6 V-Drums module. It has five PD-6 trigger pads, two CY-6 cymbal pads, one KD-7 kick drum pad, and one FD-6 hi-hat pedal. It sounds surprisingly good, with a good dynamic range and very sensitive pads. But the biggest plus is that you can turn down the volume, which you can't do on acoustic drums.
More info later. Meanwhile, here are some photos.
