Flaming Mitten has introduced Tone Pads HD – a new $1.99 matrix synthesizer for the Apple iPad:

TonePads HD is an homage to matrix sequencers such as the Tenori-On.

Featuring a 16×16 tone grid, and 5 different instrument patches.

While it’s described as an homage to the Tenori-On – it looks like it’s via the ToneMatrix.
