The device is named AnalogKick 1.0 and was done by Peter McCulloch.
The author says: “AnalogKick is a bass drum synth based on the design of the TR-808’s bass drum, and is capable of producing sounds quite similar to the original.”
In contrast to the original 808 the emulation adds some nice-to-have’s:
- FM and distortion, as
- change the tuning curve of the oscillator envelope to adjust the snappiness of the attack.
- key-following, to use it as a percussive synth with FM.
