In his Reddit AMA be said he used the Digitone for the Karma & Desire album:

K&D is all Digitone pretty much

You can also just make out a Digitone at 10:22 in the video of his The Lab performance.

A photo of a Digitakt can be seen in this post from Actress' Instagram.

The KronosX is at the front of the stage in this live performance. He uses it throughout e.g. at 3:40.

In this 2012 photo, an Octatrack MK1 can be seen behind Actress' laptop in his live setup. The photo is a bit difficult to make out given that it's somewhat blurry, but the Octatrack is nonetheless clearly visible.

In this photo from a 2012 concert, the original Zoom H4n can be seen recording the set above the rest of his setup, near the center of the photo.

At 0:18 in his 2012 Adult Swim spot, Actress can be seen sitting with his Machinedrum on the desk in front of his laptop. Unsure whether this is the MKI or MKII version.

At 0:18 in his 2012 Adult Swim spot, a Yamaha Motif workstation/arranger keyboard can be seen just behind him. While the right hand side of the keyboard is obfuscated, the green display and 3x2 white function buttons indicate the is a model from the Motif Classic (7/8) or Motif ES line (6 ES or 7 ES).

At 0:50 in his 2012 Adult Swim spot, Actress can be seen using an Elektron Monomachine alongside an Elektron Machinedrum on his desk in front of his laptop.
