Seline HD ( is a great live performance and improvisation music instrument that will keep the players entertained for hours, even those who haven't touched any music instrument before. Highly advanced CrystalClarity HD sound engine is capable of analyzing and predicting melodies, altering the sound on the fly with a dozen of subtle algorhythms that add unbelievable expression, character and life to the generated music.

Seline HD features a completely new, ergonomically designed playing surface called ioGrid, suitable for players with all hand sizes. The melodies are supposed to be played with two hands, while keeping the iPad on the knees or on the table. Fully adjustable 16-note scale is divided into 2 parts (odd and even), which are then mapped on the left and right grids. Such way of note mapping is beneficial to the existing linear scale mapping solutions as it allows many more improvisation possibilities.  Such approach also guarantees that the player is never out of tune.

Seline HD can be used to play any melody but it does have its own character and sound. The player can choose from 20 built-in factory voices (flutes, bowed strings, reeds, synth leads and more) and 9 drone voices. Drones (chorded synth pads) are generated on-the-fly based on the complex analysis of your melody line and provide an excellent background layer for the melodies.

Seline HD player is equipped with full range of recording possibilities, including direct recording to .wav files, deleting, doubling tracks. Overdubbing (layering tracks) is possible and encouraged, since it is an excellent way to create complex orchestrations. Two available onboard FX - grand stereo reverb and dub delay - are the finishing touch in the creation of the magical, delicate sonic heaven.

Seline HD is now available from the iPad AppStore at the initial price of $5,99. iTunes link:
