Some of the most responsive instrument emulations come from Moo Cow Music, whose entries include Bassist (V. 1, $2.99), which lets you trigger electric-bass sounds from a virtual fretboard with a variety of articulations; and Guitarist ($3.99), which offers several different ways to play a virtual electric guitar, and includes delay, wah, and fuzz effects. The company also makes piano, organ, and full-band emulations.
