Create better music with help from these apps

THIS week, we feature three apps which are useful for musicians and those just learning how to play musical instruments.

Guitar Tuner (which used to be known as Guitar Tuna) is a tuner for guitar, bass, ukulele and many other string instruments; Caustic 3 is a music creation tool inspired by rack-mount synthesisers / samplers rigs. Drumgenius is a real drum grooves app with 400 loops from Jazz to Rock.
