Released in 2013, Ableton’s Push was the hardware that turned its Live DAW into a playable instrument (Ableton never liked to think of it as a controller) and, through various iterations, it's been gracing stages and studios ever since.
The original Push was actually built in collaboration with Akai Pro – Ableton had previously worked with Akai on its APC40 and APC20 Live control surfaces – and was designed to bring something different and more integrated to the market.
