Sig.Gen. (pro)

Sig.Gen. is a fun to use audio signal generator with a home-made look and feel – as if it were knocked together in a garden shed. Scratch beneath the surface, though, and it’s actually a sophisticated musical gadget. The big friendly dial (which just begs to be twiddled!) allows you to set the tone of the generated signal in either frequency (Hz), or in musical notation – retro dot-matrix displays top and bottom show the equivalence between the two. Music gadget which is great for ear training, tuning, or just for fun!

What’s more, Sig.Gen. (pro) plays chords and scales! In the options menu, select between eleven popular scales:

major, major 7th, Dorian minor, blues , pentantonic (major & minor), half-diminished, bebop (major & minor) and bebop (major, maj.7th & minor)

Play these scales (or their chords) in any key!
