What is a MIDI looper? A device or plug-in that records the notes you play and repeats them, so you can change the sound after the fact.

Loop a guitar or a synth as audio and you’re stuck with that exact sound, but loop the notes and the same loop can drive a different instrument tomorrow.

Bastl’s page for its Midilooper, Ableton’s manual and a few plug-in makers show how each kind works and what each one can and can’t do.

You’ll see how a MIDI looper differs from an audio looper, which hardware and software ones exist, and how to run a looper with a foot controller.

Start with what a MIDI looper actually records.

What Does a MIDI Looper Actually Record?

It records instructions, not sound. Bastl says its Midilooper listens to control information about notes, dynamics and other parameters, and loops them the way an audio looper would process audio (Bastl).

Cherry Audio describes the same job for its software module as recording and looping MIDI notes, meaning on and off timings with velocity (Cherry Audio). What comes out of a MIDI looper is more MIDI, and something else has to turn it into sound.

That’s the whole appeal, and the next section shows why it changes how you work.

How Is a MIDI Looper Different From an Audio Looper?

An audio looper records what comes out of an instrument, and a MIDI looper records what you played on it. Ableton’s manual describes its Looper device as an audio effect that records and loops audio, with endless overdubs synced to your Set (Ableton manual).

Bastl points out that MIDI loops stay in the control domain, so many other processes can happen on top of them, such as timbre modulation and envelope changes. Cherry Audio makes the same case for its module, saying that looping MIDI preserves flexibility in the signal chain and lets you repurpose, edit and reconfigure what the notes are doing.

MusicTech notes that audio loopers have become a live performance necessity, with the BOSS RC-505 at the center of some artists’ setups, and adds that MIDI loopers aren’t so common. If you’d like a way into the hardware side without a computer, our guide to using MIDI without a computer covers what you need.

What Does a Hardware MIDI Looper Look Like?

The one the reviews center on is the Bastl Midilooper, and Bastl’s page calls it an experimental device for looping MIDI messages. Waveform Magazine’s review describes a single MIDI input, two MIDI outputs and several analog inputs for clock, reset, transpose and other modulation.

The workflow is simple. Connect a sequencer or MIDI controller to the input, connect your gear to the outputs, press record, play, and press record again to end the loop, and the review says a green light shows the loop has been captured.

Bastl says the Midilooper offers three voices that can each be assigned to a different MIDI channel, so it can control three other devices. Each voice can be recorded, muted, overdubbed or cleared, and Bastl adds that it can be controlled with a foot pedal.

Amazon’s search showed no listing for the Midilooper itself when checked on 30 September 2026, so there’s no shopping link here. Check Bastl’s page for where to buy it.

Which MIDI Messages Does a Looper Capture?

More than just notes, and it varies by product. Bastl says its Midilooper listens to notes, dynamics and other parameters, and MusicTech adds that MIDI CC lets you make changes to parameters and modulators on a loop.

The Max for Live device lists the messages it records and plays: pitch bend, mod wheel, aftertouch, polyphonic pressure and CC messages. It also has a Through button to let incoming notes pass or block them, and its author lists MPE as not supported.

Cherry Audio’s module records note timings with velocity, and its controls focus on quantization, transposition, rate and velocity. So check what a looper records before you count on it capturing a mod wheel or a pressure sensor.

Can Your DAW Loop MIDI Without Extra Gear?

Yes, and in Ableton Live you may already have what you need. Live’s manual says Live is always listening to MIDI input on armed or input-monitored tracks, and the Capture MIDI button retrieves what you just played, which helps if you forgot to press record.

When a Set is empty and the transport is stopped, Capture MIDI creates a clip on every monitored MIDI track, sets loop boundaries and detects a tempo in the 80 to 160 BPM range. The manual recommends ending your phrase on the first beat of the next bar to help it detect the phrase correctly.

If the Set is already playing, Capture MIDI uses the existing tempo instead, and you can capture over a clip on the same track to overdub. It’s a looper in everything but name, and it costs nothing extra if you already use Live.

How Do You Loop MIDI in Ableton Live Step by Step?

Ableton’s manual gives a technique for building patterns layer by layer, and it behaves like a MIDI looper. Set the Global Quantization chooser to one bar, and choose a Record Quantization value if you’d like the notes to snap to the grid.

Double-click a Session View slot in a MIDI track that holds an instrument, and a new empty clip appears with a default loop length of one bar. Arm the track, press the Session Record button, and the notes you play are added to the looping clip.

The clip overdubs as it loops, so you build the pattern up layer by layer. Press Session Record again to pause overdubbing and play along without being recorded, and press it once more to record on top.

If a take goes wrong, the manual says you can use Undo to remove the last take, or draw, move or delete notes in the Clip View’s MIDI Note Editor. Holding Alt (Win) or Option (Mac) while double-clicking the empty slot creates the clip and implicitly arms the track and launches it.

Is Step Recording the Same as Looping?

No, though it feeds the same kind of loop. Ableton describes MIDI step recording as entering notes with the transport stopped, by holding keys on your controller or computer MIDI keyboard and advancing the insert marker along the grid.

That lets you enter notes at your own pace, without a metronome or guide track. The manual says the step recording navigators can be MIDI mapped, so a pedal can move the marker while both hands stay on the keys.

Use step recording to build a loop note by note, and the overdub technique above to play one in live.

Which Software MIDI Loopers Can You Get?

There are several, and they suit different setups. The Max for Live device Timing Sensitive Midi Looper, by an author called krito, describes itself as a lightweight zero-latency looper with Playback, Recording, Overdub, Clear and Undo controls, and it follows Live’s transport (Max for Live library).

Cherry Audio’s Perpetual MIDI Looper is a module with non-destructive quantization, transposition, rate adjustment from half to double speed without changing pitch, and velocity adjustment. Homegrown Sounds sells a Midi Looper for Kontakt that it describes as working like guitar loopers, except for MIDI notes, with a large selection of record modes (Homegrown Sounds).

On Android, Volcano Mobile’s MIDI Looper records MIDI patterns on separate tracks and loops them, and its page says it needs an external MIDI device, software or hardware. There’s also a browser tool at midilooper.com with an input selector, seven output tracks and sixteen MIDI channels.

What Can You Change After You Record a Loop?

Almost everything about the sound, and that’s the reason to use one. Bastl lists transposition, velocity locking and shifting, quantization, shuffle, humanization, changing the loop length, and doubling or halving the playback speed.

The Max for Live device lists a quantization grid of eighth notes, sixteenth triplets and sixteenth notes, an amount from 0 to 100 percent, swing, delay and note-length controls. Its author says the original notes remain unchanged, which makes the quantization non-destructive.

You can also swap the instrument. Because the loop is only notes, you can send the same recorded loop to a piano patch today and a synth bass tomorrow, which an audio loop can’t do.

Can You Control an Audio Looper With a MIDI Controller?

Yes, and this is the other half of what people mean by using a MIDI controller as a looper. Ableton’s manual says the Looper device’s Multi-Purpose Transport Button is optimized for use with a MIDI footswitch.

To assign one, enter MIDI Map Mode, click the button, press your footswitch and leave MIDI Map Mode. After that, one press starts recording on an empty buffer, another switches to play, and another to overdub, and the manual says quickly pressing twice stops Looper.

Holding the button for two seconds during playback triggers Undo or Redo, and holding it for two seconds while stopped clears the buffer (Ableton manual). Our roundup of the best MIDI foot controllers covers pedals that can do this job.

How Do You Keep a MIDI Looper in Time With Other Gear?

Loopers only work if they share a tempo, and there are three common ways. Bastl says the Midilooper can be synchronized by MIDI clock or analog clock, or it can run on its own clock with tap tempo or free running.

Waveform’s reviewer clocked the looper from a Yamaha digital piano that happened to send MIDI clock, so a keyboard with MIDI clock can be enough. In Ableton, the port’s Sync switch controls MIDI clock, and Ableton’s help center warns against turning Sync on at the In port for more than one device, because that asks Live to follow several clock sources at once.

If you loop inside a DAW, you don’t need any of this, because the loops follow the project’s tempo.

Do You Need a Hardware MIDI Looper or Just Software?

Most people with a computer and a DAW don’t need hardware. Ableton’s Capture MIDI, a Max for Live looper or a plug-in covers the job, and any MIDI controller you already own can feed it.

Hardware makes sense when you want to loop without a computer, or when you have several synths and drum machines that speak MIDI and want a small box between them. MusicTech’s view is that a MIDI looper suits artists with an abundance of MIDI instruments.

Either way, the loop is only notes, so you’ll still need an instrument or synth on the end of it to make a sound.

The Bottom Line

A MIDI looper records the notes you play and repeats them, so you can change the instrument, the timing or the transposition afterward. Choose Ableton’s Capture MIDI or a software looper if you work in a DAW, and the Bastl Midilooper if you want a hardware box between your MIDI gear.

To run an audio looper hands-free, map a MIDI footswitch to Ableton’s Looper button. Whichever route you take, decide first whether you’re looping sound or looping notes.

Frequently Asked Questions

What is a MIDI looper?

A MIDI looper records the notes, velocities and other control messages you play and repeats them. It doesn’t record sound, so another instrument has to play the loop back.

What is the difference between a MIDI looper and an audio looper?

An audio looper records the sound of an instrument, and a MIDI looper records the notes played on it. That means a MIDI loop can be transposed, quantized or sent to a different instrument after you record it.

Can Ableton Live loop MIDI?

Yes. Live’s Capture MIDI button retrieves what you just played on an armed or monitored MIDI track and turns it into a looping clip, and Max for Live devices add dedicated looper controls.

Can you use a MIDI foot controller with a looper?

Yes. Ableton says the Looper device’s Multi-Purpose Transport Button is optimized for a MIDI footswitch, and you assign it in MIDI Map Mode. Bastl says its Midilooper can also be controlled by a foot pedal.

Do you need a computer for a MIDI looper?

No. The Bastl Midilooper is a standalone hardware device that sits between MIDI gear, though software loopers need a computer, phone or tablet.
