There is a free and completely functional version, called Robotic Guitarist Free.
Robotic Guitarist is a virtual guitar for your device. This application will be useful both for those that already play the guitar and learners, and even if you can't play but want to get some fun or experiment with its sounds.
â˜… Multitouch guitar emulator:
Choose a chord without having to learn finger positions and just hit the strings to get sounds recorded from real instruments. You can strum, plays arpeggio or any other desired technique thanks to two picking modes. Multitouch supported in capable devices.
â˜… Guitar lab:
You can choose among the sound of a lot of different instruments and map them to the whole guitar, or even pick a different one for each string! This will bring to you a lot of sessions of experimenting and having fun.
Sounds: acoustic and electric guitar, violin, viola, cello, flute, clarinet, oboe, trumpet, piano (two different octaves), xylophone, bell, timpani and chorus
â˜… Chord guide:
An easy-to-use interface allows you to change your chord selection on the go. You'll see at all times a diagram showing finger positions. Very useful for learners or for those who play already and need to recall a chord.
If you play a non-virtual guitar, Robotic Guitarist is your loyal electronic pocket-tuner.
It's a handy digital metronome. It has settings for speed (beats per minute) and different signatures (constant, 2/2, 4/4, etc.).
