Introducing: The Mega MIDI
Authentic Genesis FM
YM2612 or YM3438
The Mega MIDI 5’s circuitry brings in support for the YM3438, the worthiest of successors to the original YM2612. The YM3438 is the CMOS version of the YM2612 and features a much lower noise floor and overall cleaner sounding audio. If you’re looking for the original grit of the model 1 Sega Genesis, go with the original YM2612. If you’re looking for the cleaner sound of the model 2/3 Genesis, go with the YM3438.
Either way you go, the Mega MIDI still sounds great! Make sure to chose which IC you’d like before checkout.
Here is a sample of both the YM2612 and the YM3438. In each sample, there is 10 seconds of just DAC noise, then 15 seconds of C4 and C3 on one of the Time Trax patches.
Note: Due to the way that the YM2612/YM3438 multiplex their channels, there will always be DAC noise. Genuine chips means genuine audio and the DAC is a big part of that.
A Brand New Power Delivery Circuit
Ditch the 12V adapter. This new design only requires a single USB connection. The Mega MIDI 5’s new and improved power supply circuit eventually leads to dual linear regulators for both digital and analog circuitry to provide noise-reduced power. While the new power delivery circuit reduces noise substantially, if you feel that you may have a particularity noisy USB connection, you may have actually formed a ground loop. Simply use a cheap ground loop isolator to remove any and all remaining USB noise. I like this one!
Please note that the DAC on the YM2612/YM3438 is fairly sensitive to power supply noise. Users with units connected to computers with lots of fans or hard drives may notice a bit of noise on the output. You can mitigate most of this noise this by using a dedicated 5V power supply (like a phone charger) and a standard DIN MIDI connection. No chips will ever be completely noise free – remember, these are budget sound chips from over 30 years ago, that’s part of their charm!

Save Your Favorite Patches for Hot-Swapping on the Fly
You can add as many patch files as you want to the Mega MIDI’s SD card, but if you ever find any specific voice that you just love and want easy access to, simply press and hold one of the seven “favorite” buttons on the face of the Mega MIDI. Your favorite patch will be saved to internal memory. Simply press the favorite button again to instantly swap to your saved patch.
Mega MIDI Control – Directly control the YM2612 through a DAW-Compatible plugin
Mega MIDI Control is a software control panel that can directly control nearly every parameter of the YM2612/YM3438 in real time. Mega MIDI control is cross-compatible with every operating system and can even be installed as a DAW plugin (AKA, VST). You can even open and modify OPM patch files! Mega MIDI Control requires firmware version 1.3 or higher, which all new Mega MIDI’s ship with standard.
