What it does

Randomachine is a Soundevice Digital plugin, sold by United Plugins, that gives every repeat of a sample its own small differences. Each time it is triggered it re-rolls a set of effects, so copied drum hits or vocal chops stop sounding like the same file played over and over.

Pitch and formant: shifts pitch and formant by a random amount on each hit, for natural variation in tuning and tone.
Ambience: adds a varying amount of room around each hit.
Saturation: changes the drive and colour from hit to hit.
Panorama: moves each hit to a slightly different place in the stereo field.
Time offset: nudges hits off the grid, like a player who is never perfectly quantised.
Three trigger modes: Transient mode re-rolls on each hit detected in the incoming audio, Sync mode re-rolls at tempo-based intervals you set, and MIDI mode re-rolls on notes from a separate MIDI source.
Workflow: each effect has its own amount knob, and setting a knob to zero bypasses that effect; A/B comparison and undo/redo are built in.
Engine: 64-bit processing at any sample rate, click-free bypass with latency compensation, and a sleep mode that cuts CPU use during silence.

A free 15-day trial runs without saving limits or added noise, and updates are free for life.

When to use it

Randomachine is the better pick when the goal is realism rather than effect: small per-hit changes that make programmed or copied parts feel played. Compared with Effectrix2 and Stutter Edit 2, it has no sequencer, stutters or glitch patterns, and it works quietly in the background instead. It is narrower than Infiltrator 2, which stacks many creative effects with modulation, but it is cheaper and much quicker to set up for this one job. Its Transient trigger mode means it reacts to the audio itself, so it works on bounced loops as well as MIDI-driven samplers.

Best for: humanizing repeated drum one-shots, hi-hat rolls, vocal chops and copied loops.
Genres: hip-hop, electronic, pop and any beat-based production.
Look elsewhere if: you want obvious, rhythmic glitch effects; Effectrix2 or Stutter Edit 2 are built for that.
Tip: keep the amounts low; subtle randomization usually sounds more natural than extreme settings.

What producers say

The one hands-on review found sees it as a simple, effective cure for repetitive samples, with limited fine control as the main drawback.

Ableton.info review called it "more than just a randomizer", praising the easy interface, the flexible trigger modes, the six useful effects and low CPU use.
Criticisms: randomness is set per effect rather than per internal parameter, and there is little visual feedback on what is being changed on each hit.
