The Monotron range includes several specialized versions tailored for different installation needs:
The Flash Monotron is a proposed redesign of the classic single-IC monotron topology (based on the Texas Instruments SN76477 or similar analog sound chip). This paper details modifications to improve temperature stability, extend modulation routing, and integrate a flash sample memory for wavetable-like behavior. The device targets portable instrument builders and educational synth kits, offering a bridge between pure analog character and basic digital control. flash monotron
The primary voice remains analog:
The original monotron circuits are beloved for their raw, unstable analog character. However, pitch drift, limited envelope control, and lack of memory restrict their utility. The Flash Monotron addresses these issues by: The primary voice remains analog: The original monotron
Note: This paper describes a design concept. All circuits should be prototyped on breadboard before PCB layout. Flash sample rate and resolution are minimal – higher fidelity is possible with external audio codec (e.g., WM8731) at higher cost. All circuits should be prototyped on breadboard before
