The BOSS Dr. PAD DRP-II seems to have been developed with the intention of being used with a drum set, and while it's designed for playing with drumsticks, it's also possible to trigger sounds with fingers or hands, like on an MPC or rhythm machine pads. It can also be connected to the in of an electric drum. The sound source is a PCM sound source, and the built-in tones are: "BASS DRUM 1", "BASS DRUM 2", "Electric Tom", "Steel Drum", "Gong-S", and "Star Chime" - a total of 6 tones. Normally, PCM rhythm sound sources only allow for editing such as adjusting DECAY and PITCH by numerical parameters, but this BOSS Dr. PAD DRP-2 has the feature of allowing real-time editing with an analog feel using knobs. The editable parameters are "SWEEP TIME", "SWEEP RANGE", "DECAY", and "PITCH". "SWEEP TIME" and "SWEEP RANGE" are both parameters that sweep the pitch, and you can create very interesting tones depending on the settings. Also, all of these edit parameters can be changed with "knobs", so the fact that you can operate a digital sound source with the feel of operating an analog device is also a feature of this model. In addition, by setting "PITCH SENS", you can also change the pitch depending on the strength with which you hit the pad, so even though it is a PCM sound source, you can make considerable tonal changes not only in volume but also depending on the strength of the pad strike. It gives the impression of a digitalized sound source section of an analog percussion pad rather than a digital percussion pad. I tested it with a 9V battery and confirmed that all 6 sounds came out without any problems and without any crackling. There are no marks on the pads and the exterior is a very clean unit without any scratches, but the battery cover is missing. I am also listing analog synthesizers and effects units. #Electronic Percussion #Electronic Drums #Electric Drums
