Record your song ideas and demos on this 4-track device. J4T Multitrack Recorder is a basic 4-track recorder. Great for recording your song ideas and demos. Features: * 4 tracks with individual volume-controls * Export to .wav or .mp3 for desktop editing. * Import music files (.wav and .mp3). * Adjustable samplerate. * Sync option for phones where tracks are out of sync. * Copy-function for quick duplication. * Mix multiple tracks down to one to free up tracks Planned features: * Clicktrack/metronome * Stereo panning * Track editing (cut/copy/paste) * Setting loops * Adding effects (reverb/delay etc.) Issues: -The permission for reading logs is used only for reading system values necessary for reducing latency. -On some phones the recording track is still out of sync. The sync-screen can be used for manual correction. -On some phones plugging in headphones mutes the sound. The only workaround so far has been to try with different headphones. -Samplerates higher than 11025 can be problematic on slower phones. -The app doesn't work well on the Samsung Spica and the Samsung Moment. -If you experience bugs or issues on your phone, please let us know about it by sending an email so we can try to fix it.
