ScaleMaster 2.0 is nearing completion with a newly rewritten back engine, layout improvements and much more. Scales can now be displayed in 4 different ways - single staff up, single staff down, dual staff up and down (as seen in the iPhone screenshot above), dual staff down and up. These layouts are also reflected in playback which now highlights notes as they are being played. There's more to come, so stay tuned. ScaleMaster 2.0 will be a FREE upgrade for current owners.
