Then, in 2010, Korg released the Monotron.
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
: A more streamlined time switch intended for standard electrical panel mounting to manage energy consumption efficiently. Then, in 2010, Korg released the Monotron
A standard monotron drifts ~10 cents/°C. The Flash Monotron reduces this to <2 cents/°C using: The Flash Monotron reduces this to <2 cents/°C
The Flash Monotron retains the immediate, imperfect character of analog synthesis while solving the major drawbacks of traditional monotron designs. By adding flash memory for preset storage and sample playback, and improving temperature stability, it becomes a viable tool for both beginners and professional sound designers. Future work includes a 4-voice polyphonic version (Flash PolyTron) and MIDI control over USB-C.
