IsoPad is the free Windows touch MIDI keyboard. It contains three different keyboard layouts. One of them is the familiar piano fingerboard. However, the others are way more suitable for modern touch interfaces. The pads of these so called "isomorphic layouts" are organized in such a way that the interval from one pad to the next one always remains the same.

IsoPad features Play other MIDI instruments directly from your Windows touch device. Ready for Windows 8, 8.1, and 10 desktop (32 Bit and 64 Bit). Two isomorphic keyboard layouts, one classic layout. Easy to use interface, perfect for live and studio use. Multi-touch and keyboard input for jamming: Press the keys 1 to 0. Maximize screen space: Press X to hide the top row buttons. Toggle between full screen and windowed mode: Press ESC. Built-in piano sound for stand-alone usage. Three different colour schemes. "Always on top" mode. "Transparent window" mode. Very low latencies.
