The Alchemist

In this video at :15s The Alchemist is seen using a Ensoniq ASR-10 to make his music. Riggs Morales says "some of the best shit that 'Al' has hasn't seen the light yet..some of that shit is in his ASR-10 collecting dust."

In this video, The Alchemist makes a beat on his Akai MPC 2500 at 0:14 and on.

At the 0:01 mark, you can see the camera go from a blur to a more focused view. In this view, we catch a glimpse of Alchemist using the SP 303. It’s hard to make out at first, but you can see the classic SP pads, and it looks like there are only 2 rows of pads (8 pads total). This looks like the SP 303.

At 57:37 in this video a Digidesign Digi 002 can be seen in the background while Alchemist and Prodigy work on another classic tune.

In this ig video [the alchemist] set up is being shown up. In [0:10] we can see SP-404MK2

At the end of the video you can see him mixing on an 8 channel Digidesign console.

In this Youtube video at 0:30 The Alchemist can be seen using MACKIE 1402 VLZ3. In a session with Boldy James and Conway the Maschine.

In this Youtube video at minute 34:10 The Alchemist it's seen making an interview in front of his desk with the rack behind him. Here you can see the Roland RE-301 Chorus Echo under the Avalon 737.

The Alchemist is confirmed to use the Solid State Logic BiG SiX 18-input Desktop Analog Mixer and Interface, as evidenced by a photograph from a Los Angeles Times article where the mixer is visible behind him on his right. This suggests it has replaced the Mackie mixer that previously occupied the same spot.
