6 AI BandMate Apps That Interact and Inspire You Creatively

There's been a surging interest in AI chat bots these past couple of years, but imagine how helpful it could be to have a full on AI bandmate!


AI can take on any personality, so you can decide what kind of person you want to be creative with and then make music. When you get stuck, you have someone to talk to and share the ideas with. They can compose ideas in a given style and help you move a project along.


AI Bandmates might not be able to solve every problem we have on day one, but they will be rise in prominence as collaborative AI music tools designed for musicians become a common part of every AI DAW.

What is an AI bandmate?


The expression AI bandmate refers to any software that simulates the experience of a human music collaborator, by means of artificial intelligence.


As a new and growing field, there are several competing terms that have also been used to describe AI bandmates. Some of these include AI band member, AI music copilot, and AI music assistant.


There are also terms that frame the service in terms of what it does, rather than what it appears to be. For example, companies might refer AI music collaboration rather than calling it a "collaborator".


An AI bandmate could also refer to scenarios where AI is used to revive existing musicians from a band or mimic them in some way. A recent, popular example of this was the use of stem separation technology to recover John Lennon's voice from a poor-quality Beatles recording. McCartney announced that they would release it as one of the "final" Beatles songs. It's important to note that there was no generative or collaborative AI involved in this process.


Voice transfer technology similarly allows people to "collaborate" with famous artists by impersonating their voice. This isn't a true collaboration, but rather a use of AI voice-to-voice or text-to-voice technology.


6 AI bandmate apps for musicians


The idea of an AI bandmate seems to imply traditional live instruments like guitar, bass, and drums. We will include some apps that fall into that category, along with other programs that offer the collaborative experience to all musicians, regardless of their chosen genre or instrument.


Logic Pro 2 - AI Session Players

Logic Pro 2 AI session musicians

Apple has been offering a Drummer app since 2013, when they initially launched Logic Pro for MacOS. In May 2024, they made a big update and introduced tonal instruments.


Logic Pro 2 now includes an AI bassist and AI keyboard player that understand your chord progressions and rhythm choices. They've dubbed these smart instruments "AI Session Players".


This is the first time in history that a DAW has offered this kind of accompaniment with state of the art artificial intelligence. Users have a wide range of timbre and expressive styles to choose from on each instrument, ensuring that their demos sound authentic enough to enjoy on their own.


EZDrummer 3 - Bandmate


EZDrummer has been a popular drum VST for years. The DAW plugin offers a collection of studio quality drum recordings, neatly organized into loops and one shots. Each loop is built from MIDI triggers, making them easy to customize and modify as needed. As a guitarist, I've personally used it to better imagine what new riffs would sound like if I brought in a session drummer.


How does the EZDrummer 3 bandmate feature work?


The AI bandmate feature in EZDrummer saves users time by detecting music input and programming complimentary drum ideas automatically. Choose from a variety of genres to ensure that it matches stylistically.


To get started, record a riff or upload audio/midi files into the plugin. The system will analyze the tempo and time signature of your music. It even detects rhythmic syncopation and takes it all into consideration before making its suggestion.


Once these steps are complete, you will be presented with a range of matching grooves to choose from.

How do you get the best drum beats from EZDrummer 3?


You'll get the best results from EZDrummer if you input clean instrumental tracks rather than heavily distorted ones. The plugin uses transient detection for the placement of its kick hits, so effect layers like distortion and delay can throw it off.


EZDrummer 3 amount knobs

When you find a groove that resonates with you, use the "amount knobs" to refine the how many snare hits, kicks, and crashes make it into the pattern. There are also knobs that control the velocity and swing of your groove.

After these adjustments have been made, you can drag and drop the beat from Bandmate's timeline into the song track in EZDrummer 3. Here you'll find advanced editing features like the grid editor, which is basically a piano roll for drums. Your final step is to drag the beat into your DAW so that it becomes part of the project.


MelodyStudio - AI Chords & Melodies for your lyrics


MelodyStudio is a web app for lyricists who want help writing melodies and chord progressions. Upload your lyrics and the app will start by suggesting chord progressions that could go along with them.


Just like a regular song chart, each chord change is positioned above a word in the song. You can play it back and sing along to come up with your own melodies.


new melody option

Maybe you'd also like help writing a good melodic idea for the suggested chords. It's exactly the type of thing a band member could help with. Select the Melodies tab and click the New Melodies button to generate some melodic ideas.

chord variations

From here, audition each option using the MIDI playback feature to hear what they sound like. Select the option you want and the app will automatically add the melody to your main lyric sheet.


MelodyStudio includes a MIDI piano roll editor. This is what elevates the app from a music generator to a true AI bandmate. You can collaborate with the software by changing the duration and pitch value of the notes until it matches the feeling that you're going for.


chord progression with lyric matching

Once the chord progression and melody are locked in, you can even export the MIDI file and bring it over to your DAW. Make use of your best virtual instruments to improve the sound design. Then record your vocal performance and you've got a full track. MelodyStudio includes a guide for music producers if you want to learn more.


Oslyn - Digital Bandmate for Guitarists


Oslyn is a mobile and web app that performs realtime analysis of your guitar performance and adds ambient pads. The AI chord detection feature shows you the name of the chord you're playing and generates the same collection of notes. According to the website, users can train the AI to become more familiar with their playing style and generate chords with greater accuracy.


Their product is currently in private beta and has been marketed to people performing in religious services. They seem to be going for guitarists who want a warm and enveloping sonic landscape during worship, but don't have a keyboard player on hand.


Auto-detect chord progressions and lyrics

Oslyn features:

  • Sustain a chord on the synth pad even after the guitar chord is no longer being played

  • Loop a chord progression once the full pattern has been performed

  • Record your vocals for automatic voice-to-text lyric transcription with chord accompaniment

  • Review your recorded song with guitar tablature in the web app


Despite serving a relatively narrow use case of church guitarists, Oslyn does represent a meaningful effort at creating an AI bandmate in the truest sense.


WavTool - AI Assistant powered by GPT-4



WavTool is an AI DAW that runs in your web browser and comes equipped with a text-to-music assistant. You can prompt it to create short loops, act upon elements in the DAW, and even generate melodies. We've been in ongoing discussions with their founder, who is currently making improvements on the MIDI melody and chord progression generator.


WavTool AI bandmate expands on MIDI

WavTool's latest innovation is an option to expand on existing MIDI. The DAW will come up with MIDI riffs based on your text input. You can also record your own ideas. Based on this MIDI input, it will suggest a few different ideas on how you could continue that melody. You can select from these options or speak to the AI assistant directly using the GPT-4 powered chat tool.


This collaborative approach to composing is much closer to what it feels like in a true musical relationship. As the quality of WavTool's output improves, the realism of this experience will also get better. Read our full summary of WavTool to learn more.


Meta MusicGen - AI melody accompaniment


MusicGen represents the latest in text-to-music generation. Published by Facebook-Meta, the software currently runs inside of HuggingFace and has a relatively simple user interface. There are a couple of best practices to be aware of, which we've covered in this featured article about MusicGen.


Melodic conditioning with input text is the collaborative element that makes MusicGen interesting. Instead of simply setting some parameters, you can upload yourself singing, whistling, humming, or even playing an instrument.


For a better user interface and more audio editing features, check out the new SoundGen app. They've created a user interface built around the MusicGen model, with better prompting tools and file management tools.


The text that you provide MusicGen will dictate the style of audio that it produces. We've created a demonstration below, where we used AudioCipher's text-to-midi VST to create a melody and express it through 15 different genres of music:



Why are AI bandmate apps so rare?


Musicians can clearly benefit from AI bandmate apps, but these software companies tend to receive less funding because investors consider them to be higher risk. The AI web apps that I referred to previously as "instant-song generators" have secured the majority of venture capital to date.


This trend comes down to perceptions about the total addressable market (i.e. number of potential customers and revenue). VC firms want to see meaningful returns and bigger markets seem to represent bigger opportunities. They could be right - or they might be making a critical error!


Investors want a slice of the royalty-free music licensing pie. That's why their AI music portfolios focus on the "creator economy" instead of the smaller digital musician market. They are betting on social media creators going for low-cost, generic background music over pricier content from Artlist, Epidemic Sounds, and so forth. There's not enough public data to know whether their gamble has paid off yet.


Amateur vocalists and beat makers are a second, smaller cohort that AI song generator apps target. Their marketing teams focus on parameters like BPM and key signature for this audience, framing the song generation tools as collaborative. But that's a bit of a stretch - content creators have had the option to filter by similar attributes in the past. Those libraries are resources, not collaborators.


A diverse portfolio of smaller collaborative AI bandmate apps could offer a novel approach to AI music investment. However, there might not currently be enough product experts in the field who have built partnerships with founders, to curate this kind portfolio on behalf of investors.


As AI music tools mature and founders can demonstrate real opportunities for profit, there will be a sea change with a corresponding growth in the number of AI bandmate programs on the market. For now, it's up to consumers to support these companies and vote with their dollar.
