In this study, an analog synthesizer module using Aloe vera was proposed as a biomemristor. The recent revival of analog modular synthesizers explores novel possibilities of sounds based on unconventional technologies such as integrating biological forms and structures into traditional circuits. A biosignal has been used in experimental music as the material for composition. However, the recent development of a biocomputor using a slime mold biomemristor expands the use of biomemristors in music. Based on prior research, characteristics of Aloe vera as a biomemristor were electrically measured, and two types of analog synthesizer modules were developed, current to voltage converter and current spike to voltage converter. For this application, a live performance was conducted with the CVC module and the possibilities as a new interface for musical expression were examined.
