IsoPad is the free Windows touch
MIDI keyboard from FeelYourSound.
Use your Windows tablet to play any
electronic MIDI instrument with your fingers.
Connect IsoPad to your DAW and use
one of three included keyboard layouts to play
melodies, basslines, and hooks quickly.
The isomorphic layouts are optimized
for touch screen usage: Chord and scale shapes will
always look the same no matter which root note you
use. If you know how to play a C Major chord, you
instantly know how to play an A Major chord for
example. Just keep your fingers in the same position
and move them to the A.
