About this app

🎹 YOUR COMPLETE MIDI AND KARAOKE STUDIO ON ANDROID

MIDI Clef turns an Android phone or tablet into a full music workstation. Play MIDI files, MOD trackers and CDG (MP3+G) karaoke, follow synchronized lyrics and chords on screen, plug in an external MIDI keyboard, and capture your own karaoke covers — with the responsiveness and sound quality you'd expect from dedicated hardware.

WHAT YOU CAN DO WITH MIDI CLEF
• Play MIDI, MOD and CDG tracks with real-time visualization
• Load your own SoundFonts (SF2, SF3, SFZ) and assign custom presets per channel
• Read lyrics and chords live, with fully customizable fonts, colors and a background of your choice — even an image or video
• Record karaoke in one tap, with reverb and chorus on the vocal
• Reshape any MIDI on the fly: transpose, change tempo, swap instruments, adjust pan, chorus and reverb per channel
• Solo or mute individual channels when you want to focus on a single part
• Shape your sound with a 6-band equalizer and an effects chain that includes reverb, chorus, pitch shift and damping
• Drop markers and loop between them to drill tricky passages
• Per-file presets that reload automatically next time you open the track
• Connect an external MIDI keyboard and use MIDI Clef as a sound module
• Layouts designed for both phones and tablets

SUPPORTED FORMATS AND STANDARDS
• Standard MIDI (SMF 0/1, RMI), with GM, GS, XG and XF, including embedded lyrics and chord names
• CD+G / MP3+G karaoke tracks
• MOD trackers: IT, MOD, MTM, S3M, UMX, XM
• SoundFonts: SF2, SF3, SFZ
• Audio: AAC, AIFF, FLAC, MP3, OGG, WAV
• Lyrics: enhanced LRC and NCN karaoke (LYR/CUR files, also inside EMK containers)

ORGANIZE AND PRACTICE
• Build playlists for gigs, lessons or rehearsals
• Pin markers and loop between any two points
• Keep music playing while you switch to your sheet-music or notes app

SHARE YOUR PERFORMANCE
• Export the final mix, vocals included, to AAC or lossless FLAC
• Send it to any app in one tap

Great app so far, but I have suggestions; 1. The song that is currently playing in the app still continues through ads. 2. You are unable to change the pitch and other settings on audio and MOD files, except Chorus, Reverb and Equalizer. (I'm not sure if there is something stopping this, but this should be in if there isn't) 3. You are forced to always use the soundfont at top's instruments and they always replace the others and only extra instruments can play from them.

Thank you for your suggestions. Clicking on a SoundFont opens the list of its instruments, where you can selectively disable each one of them: in this way the instruments of the SoundFont next in the list will be used. You can check which instrument is played by each SoundFont by the presence of the green dot near it.

Most bang for the buck in my lifetime!!! Played with it for 30 minutes and paid for it! Worth every penny. I have over 6 GB of soundfont files loaded, from 2 MB, to a bit more than 4 GB. I swap them back and forth while it plays to see what I like for a particular song; dragging the one you want to the top is easy. Plus, you can choose any specific instrument from any soundfont for any part. There is an A-B loop function. The "scissors" icon. And the loop, or the whole song can be exported fast!

This app is not good for black midis. It lags on midis with max Notes/s of >10,000. It also can't load more than ~1.25 million notes. The reason why I don't rate it one star is because it didn't lag on a black midi that had ~150,000 notes. Please optimize this midi player for black midis and remove the midi file size limit.
