Quaver is a musical calculator and look-up tool for recording
engineers and composers. It can calculate the delay times and
oscillator frequencies that match a given tempo to help keep
things in sync. Its pitch tool can tell you the fundamental
frequency of any note in the MIDI range - or perform the reverse
calculation. Finally, the scale tool can tell you the notes that
make up a given scale and draw the key signature.

What's New in Version 1.3
Quaver now includes a synthesiser. This allows you to hear notes as you make your selection in the pitch view. You can also preview scales in the scale view.
Quaver also now accepts input fro MIDI devices. You can use a MIDI keyboard to make selections in the pitch view.
