"In the 1980s, when techno-pop was at its peak, analog drum synth gadgets that were made by manufacturers of various sizes but are now endangered. Beat Happening is the royal road to the modern age when analog drum synth sounds are oblivion or beyond.By applying vibration to the black rectangular pad on the top of the main unit, pleasant (?) Sounds such as "Pyo-n", "Pasha-n", and "Kinkin", which are unique to analog drum synths, pop out. By adding a built-in pitch-swinging modulation to it, a retro game-like cheapness is reproduced.
On the surface of the main body, there are "Ptich (slider)" that determines the pitch, "Sens" and "Decay" that control the effect of the envelope, "Sweep" that controls the rise and fall of the pitch, and its ON / OFF switch and modulation effect. "Depth" and "Rate" that control the depth and speed of the cycle, the master volume on the right side, the "HOLD" switch that keeps outputting the synth sound regardless of the vibration to the pad, and the lower side of the main unit Is equipped with an “EXT.INPUT” jack that triggers the input signal. Since you can input an audio signal to this EXT.INPUT and control the sound of the main unit by that input, connect an external drum pad, a sound source such as a click or kick drum, and even a guitar, and every time you pick the guitar, " You can also enjoy the act of making a sound like "Pyon". It is a tool that allows you to easily enjoy cheap and kitsch analog drum synth sounds, which are rarely heard nowadays, but with a full-fledged operation feeling."
