ADLMIDI-Player-Java
Implementation of ADLMIDI based MIDI-player for Android
It's a MIDI-player based on emulator of a Frequency Modulation chip Yamaha OPL3. This small MIDI-player made with using of libADLMIDI library - a fork of original ADLMIDI a console program implementation.
Key features
- OPL3 emulation with four-operator mode support
- FM patches from a number of known PC games, copied from files typical to AIL = Miles Sound System / DMX / HMI = Human Machine Interfaces / Creative IBK.
- Stereo sound
- Number of simulated OPL3 chips can be specified as 1-100 (maximum channels 1800!)
- Pan (binary panning, i.e. left/right side on/off)
- Pitch-bender with adjustable range
- Vibrato that responds to RPN/NRPN parameters
- Sustain (a.k.a. Pedal hold) and Sostenuto enable/disable
- MIDI and RMI file support
- Real-Time MIDI API support
- loopStart / loopEnd tag support (Final Fantasy VII)
- 111-th controller based loop start (RPG-Maker)
- Use automatic arpeggio with chords to relieve channel pressure
- Support for multiple concurrent MIDI synthesizers (per-track device/port select FF 09 message), can be used to overcome 16 channel limit
- Support for playing Id-software Music File format (IMF)
- Support for custom banks of WOPL format
- Partial support for GS and XG standards (having more instruments than in one 128:128 GM set and ability to use multiple channels for percussion purposes, and a support for some GS/XG exclusive controllers)
- CC74 "Brightness" affects a modulator scale (to simulate frequency cut-off on WT synths)
- Portamento support (CC5, CC37, and CC65)
- SysEx support that supports some generic, GS, and XG features
- Full-panning stereo option (works for emulators only)

System requirements
- Recommended to have powerful CPU: Emulation of OPL3 chip is a sound generation by formulas which requires requires operations. For example, application works almost fine on Samsung GT-I9300 which has quad-core Exynos 4212 CPU with 1400 Mhz. On slow CPUs it may lag, for example, on LG-E612 with MSM7225A Cortex A5 with 800 Mhz.
- 4 MB free space
How to install
- Put APK to your Android device
- Check in settings that custom applications installations are allowed
- Open APK via any file manager and confirm installation
- Allow external storage reading (needed to open MIDI-files from phone memory and SD Card)
How to use
- Use "Open" button to open file dialog and select any MIDI, RMI, KAR or IMF (Wolfinstein 3D) file
- Setup any preferences (bank, tremolo, vibrato, number of emulated chips, etc.)
- Press "Play/Pause" to start playing or press again to pause or resume
- Press "Restart" to begin playing of music from begin (needed to apply changes of some settings)
- Use "Open" again to select any other music file
- You can switch another application or lock screen, music playing will work in background.
Tips
- This application audio playback may lag on various devices, therefore you can reduce number of emulated chips
- If you are using "4-operators" banks, you can increase number of 4-op channels into number of chips multiped to 6 (each OPL3 chip supports maximum 6 four-operator channels). Or simply use "" mode which will automatically choose count of necessary 4-operator channels in dependence on a bank.
- Set number of four-operator channels into zero if you are using 2-operator banks (most of banks are 4-operators. Pseudo-four-operator banks are 2-operator banks with double-voice support)
