What is Megalovania?
Megalovania is one of the most iconic video game music tracks ever composed. Created by Toby Fox, it serves as the boss battle theme for Sans in the Genocide Route of Undertale (2015). The track is known for its fast tempo (240 BPM), energetic electronic-rock style, and memorable melody that has become a cultural phenomenon.
Interestingly, Megalovania was originally created for a Homestuck fan game called "Radiation's Halloween Hack" before Toby Fox repurposed it for Undertale. The track has since been covered, remixed, and arranged thousands of times by fans worldwide.

How to Get Megalovania MIDI in 5 Steps
Step 1: Upload Your MP3
Go to the MP3 to MIDI Converter and upload your Megalovania MP3 file. You can drag and drop the file or click "Choose MP3 File" to browse your device. The converter supports files up to 5 minutes — the full Megalovania track (2:35) fits perfectly.

Step 2: Select Audio Type
Choose the audio type that best matches your MP3. For Megalovania, we recommend:
- Piano — if you want a piano-only arrangement
- Full Song — to capture all instruments (guitar, synth, drums, etc.)
- Not Sure — uses balanced settings for mixed audio

Step 3: Convert
Click "Convert" and wait for the AI to analyze your MP3. The process runs entirely in your browser — no upload to any server. Conversion time depends on your device's performance, but most tracks complete within 30-60 seconds.

Step 4: Edit & Download
Once conversion is complete, you can preview the MIDI and edit it in the piano roll editor. Adjust detection sensitivity, remove unwanted notes, or fine-tune the transcription. When you're satisfied, click "Download MIDI" to save the file.

Beyond the Download: What to Actually Do With a Megalovania MIDI
Most "get the MIDI" guides stop exactly where your problem starts — the moment the file lands on your device. Here is what differs when you convert Megalovania yourself, and how to make the resulting file genuinely useful instead of a noisy blob.
What a converted Megalovania MIDI usually contains
Because Megalovania is a dense electronic-rock arrangement, the transcription typically comes back in a few streams rather than one merged mess. Expect to see a clear lead (the memorable synth hook), rhythm guitar/bass sustain, a squeaky-clean top melody, and percussion. In our piano-roll editor you can solo each stream by clicking it, which makes it far easier to tell what the AI actually heard.
Three things that actually improve the result
- Slow it down before judging it. Megalovania runs at 240 BPM, so fast 16th-note passages sound frantic at full speed. Drop the playback tempo to 50% first, check the structure, then return to 240 BPM. Chords and bass lines that look "wrong" at speed are often simply dense, not incorrect.
- Kill ghost notes with one trick. In sections where the lead and the rhythm guitar overlap, audio-to-MIDI tools occasionally write a few stray low notes. Select the lead stream, then remove any notes an octave below it — this cleans the file without touching the real melody.
- Mute everything but the lead to practice. If you are learning the solo or making a cover, hide the bass and drums and keep only the lead stream. On most MIDI files that single filter turns an overwhelming track into a practice part.
Realistic expectations for a 240 BPM electronic track
No audio-to-MIDI converter transcribes a heavily distorted, hard-panned electronic-rock mix note-perfectly — including paid desktop software. Dense drum fills and saturated guitar often lose a few hits. That is normal, and it matters less than you think: the melody, bass, and chord skeleton you keep are exactly the parts that survive well. If you need a note-for-note piano score of the riff, isolate the synth lead before converting; if you want the full mix, accept the small losses and clean the bass/drums in the editor.
