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.
Many minor updates and improvements.

Can't imagine making music without it
Absolute time saver in trying to figure out keys and frequencies
Handy Little Music Utility App!
Quaver is an extremely useful music utility app. It’s great for keeping the pulse of a track (instrument or effect) in sync with the BPM of a song. I mostly use it to figure out delay times, and it can also be used to calculate oscialltor freqs. The scale tool is a bonus — lists the notes withing a chosen scale. It’s been years since my college music theory classes. The only key I have memoried is the key of C. ;-) All in all, Quaver is a fantastic bargain! I’ve gotten my money’s worth out of this fine little app a dozen times over.
*Cost less than my guitar pick
