Seline for iPhone released

The iPhone version of Amidio’s Seline HD is released. Here’s the new app’s description:

Seline is a great live performance and improvisation music instrument that will keep you playing for hours, even if you haven’t touched any music instrument before. Amidio’s advanced CrystalClarity HD sound engine now is capable of analyzing and predicting your melodies! The sound is altered on the fly with a dozen of subtle algorhythms that add unbelievable expression, character and life to your music.

Seline features a completely new, ergonomically designed (finally!) playing surface called ioGrid, suitable for players with all hand sizes. The melodies are played with two thumbs and accelerometer (“VariSlide”). 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. And, of course, the player is never out of tune.

Seline can be used to play any melody but it does have its own character and sound. The player can choose from 25 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 your melody.

Seline 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™ Music Instrument - Amidio Inc. Clip to Evernote


  1. Bought Hexatone from amidio for €8 which didn't work on the new ipod
    never got any reply to emails and no replies to questions on the forum from others no support at all…….

  2. If you look on their forum, the hexatone part,
    there already is an old message “not 4.0 compatible”
    with zero replies.
    In the bottom appstoreinfo there isn't the usual line with
    “” ios 4.0 tested “”

  3. Yeah, Amidio isn't really great on the support front. They kinda just launch'em and leave'em. Something they need to and can improve on.
