Advanced Step Sequencer: Independent Loop Points, Scale-Locked
Most step sequencers give you one loop length and ask you to work inside it. Advanced Step Sequencer by Rozzer does something different: every element of the sequence — notes, gate, tie, velocity and the parameter lanes — can have its own loop points. Set the note lane to 16 steps and the velocity lane to 7 and the two go out of phase, resyncing only every 112 steps. That single design decision is what separates it from the Step Sequencer that ships with Max for Live.
The second design decision is scale-awareness. The grid isn't a chromatic piano roll with rows you have to remember to avoid. Pick a scale and the grid redraws itself to match. Chromatic gives you twelve rows. Pentatonic gives you five. You're not filtering wrong notes out after the fact — they were never on the grid to begin with.
What's actually in the device
It's built on live.grid, so the interface is the familiar clickable matrix rather than a list of numbers. The lanes are:
- Notes — pitch, constrained to the chosen scale
- Gate — whether a step fires
- Tie — whether a step holds into the next
- Velocity
- Five direct parameter control sequencers — in version 2.0 these replaced the two MIDI CC sequencers from earlier versions
That parameter-control change matters more than it sounds. Instead of sending CC and hoping something downstream is listening, you point a lane at a parameter in Live and it drives it directly. Filter cutoff on the instrument below, a send amount, a device macro — each on its own loop length, each stepping in its own cycle.
There's also a set of randomization options, which is where a lot of the practical value hides. Randomizing inside a locked scale produces usable material rather than noise, and that's the difference between a randomizer you press twice and one you leave under your finger.
Three ways this changes a session
The 303-style bassline that doesn't need a clip. Set the scale to something narrow — minor pentatonic, say — drop a mono synth after the device, and program sixteen steps with the tie lane doing the work. Ties are what make acid lines behave: held notes trigger slides and filter behaviour a series of separate notes won't. Keep all lanes at the same loop length and you have a conventional, repeatable pattern. Then pull the gate lane down to 15 steps and let it drift against the notes. The same pattern starts breathing without you touching it.
Generative melody on a long timeline. This is where the independent loop points earn their keep. Notes on 12, velocity on 5, gate on 7, one parameter lane on 9 driving a filter. Nothing repeats in a way a listener can predict, but every note is in key and every accent is one you drew. Run it under a pad or a plucked instrument and record a few minutes of MIDI to a clip, then comp the good bars. Using a generative device as a source for material you later edit is often more productive than using it live — you get the surprises without committing to them.
The rack trick. Rozzer's own suggestion, and it's the right one: put several instances into separate chains of a MIDI Effect Rack, each with its own instrument. Different scales per chain, different loop lengths per lane, and you get polyphonic polyrhythms that no single sequencer could produce. Use chain selectors to bring voices in and out and the rack becomes a small arrangement engine. This is the configuration to build once and save as a preset, because rebuilding it from scratch every session is tedious.
What 92,784 downloads and a 5/5 rating tell you
The device landed in March 2010 and was last updated in April 2025. Fifteen years of maintenance is unusual in this catalogue, and the version history is the kind you like to see: fixes for unresponsive buttons under Live 9 and Max 6, proper naming for automatable parameters, then the 2.0 rewrite for Live 10 that swapped CC lanes for direct parameter control. Someone kept using it and kept fixing it.
Ninety-three thousand downloads against a perfect rating and 63 comments means the device survives contact with a lot of different setups. A high rating on a device with 200 downloads tells you little. A high rating on a device that's been installed almost a hundred thousand times tells you the concept holds up. If you're picking one advanced sequencer to learn properly, this is a safe bet.

Where it sits among the alternatives
The MIDI Effect category has a dense cluster of sequencers around the 90–100k download mark, and they solve genuinely different problems.
ML-185 Stage Controlled Sequencer by 3st is the closest relative in spirit and the furthest in method. It's stage-driven: eight configurable stages, three layers (pitch, velocity and an aux layer for pitch bend or CC), four play modes per stage, and variable stage length from one to eight clock pulses. Where Rozzer's device creates motion by desynchronising lanes, ML-185 creates it by making each stage a different length. If you've worked with hardware analogue sequencers, ML-185's model will feel native. Note it's version 0.9 and targets Live 8.1 — it's an older build and hasn't been updated since 2009, though it's still on 94,904 downloads and a 5/5 rating.
MDD SnAkE by maximedangles takes a third route: shapes rather than grids. You draw or choose a shape and the sequence follows it, with MIDI-mappable shapes and root note control from C4 to B4. It's the most recently maintained of the group (3.2.3, Live 10.1.25) and the fastest to get sound out of. If Advanced Step Sequencer is for building a pattern step by step, SnAkE is for gesturing at one. There's a longer look at SnAkE if you want the detail.
POLYRHYTHMUS by bennniii is rhythm-first and pitch-second — a modular Euclidean builder with 99,404 downloads and 101 comments, the most-discussed of the set. Use it for drums and for pattern generation where the distribution of hits matters more than the melody. It pairs well with Rozzer's device rather than competing with it: POLYRHYTHMUS for the groove skeleton, Advanced Step Sequencer for the melodic lines on top.
Also worth knowing that not everything filed under MIDI Effect is a sequencer — Grain.Freeze by monolake sits in the same category list but is a granular audio freezer. Useful to have on the far end of a chain, irrelevant as an alternative here.
Who should skip it
Skip it if you want a drum sequencer. The scale-locked grid is built around pitch, and forcing it to drive a drum rack fights the design. POLYRHYTHMUS is the better tool there.
Skip it if you're running Live 9 or earlier. Version 2.0 requires Live 10.0.5 and Max 8.0.0, and the parameter-control lanes are the main reason to use the current version.
Skip it if you want to hear something in ten seconds. This is a device with lanes, loop points and scale settings, and it rewards a session spent learning it. SnAkE will give you a result faster.
And skip it if you want chromatic freedom above everything. The scale lock is a feature, not a limitation, but if your writing depends on passing tones and borrowed chords you'll spend your time in chromatic mode — at which point you've given up half the point of the device and could use a simpler grid.
For everyone else: start with a mono synth, minor pentatonic, sixteen steps, then set the velocity lane to a different length and listen for a minute. That one move explains the whole device.
