I currently have volunteers managing the German, Dutch, Danish, Swedish, Finnish, French, Spanish, Italian and Czech translations of BandHelper. Czech and Swedish could use some extra help. I've also had offers to add Turkish and Greek, but I'd like to have at least one more volunteer for those languages before adding them.
Beta testers will receive new versions 1-2 weeks before the public and will provide feedback on real-world use. The ideal beta testers use some of BandHelper's advanced functionality (e.g., database sync, Bluetooth, MIDI, multi-page charts) and can clearly describe any problems they find.
Please for more details.
