Elektron have posted a YouTube video featuring their newly-released Analog Keys synth in action. Here's their description of it...
"During this session, audio output of Analog Keys is being fed into the Octatrack. On the Octatrack, Track 1 has HOLD Record mode with Flex Buffer 1 assigned. Track 2, 3 and 4 have Pickup Machines assigned and are set to Loop 64 Steps of audio. Tracks 5, 6, 7 and 8 have sequenced drum samples and loops. By this setup, the Octatrack can act as a looper, drum machine, FX processor and a mixer while Analog Keys provides the warm and fat synthesis.
At 2:23, Octatrack is switched to next Pattern which has a different Part assigned to it. On this Part, the same recorded samples from the Analog Keys are played back backwards. This features makes the Octatrack a crazy looper with unforeseen capabilities."
