ToneKey 1.0 for Mac can be downloaded from our website for free. ToneKey for Mac lies within Audio & Video Tools, more precisely Music Production. The actual developer of this Mac application is TONEKEY LTD.
From the developer:
Any of ToneKey's thirty three different scales from around the world are made instantly playable without error, providing a fast and failsafe means of consistently playing harmonious music within a stable harmonic structure. This is facilitated using a Customisable Scale Mapping strategy. This strategy takes advantage of the symmetrical layout of the keyboard together with MIDI protocol?s digitisation of musical information.
