Tips for Best Black Knife MIDI Results
Use High-Quality Audio
For the best MIDI conversion, use high-bitrate MP3 (320kbps) or lossless formats like WAV/FLAC. Avoid low-quality rips or compressed audio that may lose detail during conversion.
Select "Full Song" for Complete Arrangement
Black Knife features multiple instruments including synths, strings, and percussion. Selecting "Full Song" captures all elements. Use "Drums" if you only need the percussion track.

Black Knife runs at approximately 147 BPM. After conversion, verify the tempo in our editor and adjust if needed. Some audio versions may have slight tempo variations.

Beyond the Download: Working With a Black Knife MIDI
Getting the file is only half the job. Here's what to expect when you open a Black Knife MIDI in an editor, and how to make the most of it.
What the converted file usually looks like
Because Black Knife layers orchestral strings, driving percussion, and synth leads at around 147 BPM in C major, a full conversion typically splits into several tracks — a lead melody, a bass/rhythm layer, and a separate percussion part. Open them in a piano roll and solo each track to separate the melody from the accompaniment before editing.
Three things to check right after converting
First, glance at the tempo marker — most rips land very close to 147 BPM, but a slightly detuned or stretched source can shift it. Second, skim the bottom of the piano roll for stray low notes that sometimes appear where the kick drum overlaps the bass; deleting those keeps the line clean. Third, listen at half speed if the dense sections look cluttered — Black Knife's fastest passages are easier to verify when the playback is slowed down.
Set realistic expectations for fast boss themes
Not every note will survive transcription perfectly. Dense drum hits and distorted synth stabs are the hardest parts for transcription to separate cleanly, so a few ghost notes or a missing double-strike in the percussion is normal. The melody and string parts, by contrast, usually come through with high accuracy — which is what most people actually want to play or remix anyway.
