For a synthwave track locked to 120 BPM, Loudly is the clearest fit in this roundup: its documented controls include genre and BPM, and synthwave is one of its listed genres. AI Game Music Generator also has a verified synthwave example and lets users fine-tune tracks, but its supplied details do not establish a BPM control. If exact tempo matters, confirm the result in the tool before building a video, game loop, or edit around it.
What A 120 BPM Synthwave Track Needs
120 BPM gives a steady four beats per bar in common time, which makes it a practical target for driving electronic music, edits, and repeated visual cuts. The number alone does not make a track synthwave. For the sound, describe the musical character in the prompt: a pulsing analog-style bass, bright arpeggiated synth notes, wide sustained chords, gated or roomy drums, and a melodic lead with a retro-futurist mood. These are creative directions for a prompt, not confirmed presets or instrument controls in either service.
Specify the arrangement as well as the sound. A useful brief might ask for an instrumental intro, a gradual build, a full-energy section, and an ending that resolves cleanly. If the track is meant to loop, ask for a loop-friendly ending and listen for a smooth join; neither provided listing confirms a dedicated seamless-loop feature. Keep the request focused: too many competing scene details can distract from the tempo, groove, and synth parts that define the brief.
For example, try: “Instrumental synthwave at exactly 120 BPM, steady four-on-the-floor kick, pulsing bass, crisp snare, bright arpeggiated synth, wide warm chords, nostalgic night-drive mood, gradual intro, energetic middle, clean resolved ending.” Treat this as a starting prompt. The available product information does not establish that either generator understands every musical term or will honor every instruction, so check the generated audio rather than assuming the wording guarantees a result.

Best AI Synthwave Generators For 120 BPM
1. Loudly — Best For Setting A Specific Tempo
Loudly is the strongest match when 120 BPM is a firm requirement. Its generator supports creating music by genre and BPM, and its listed genres include synthwave. The product information also says users can prompt a track or use a song formula, then refine energy, key, BPM, structure, instruments, and duration. That combination maps directly to a tempo-led brief: select or prompt synthwave, set BPM to 120, and shape the arrangement and duration around the intended use.
Try a prompt such as: “120 BPM synthwave instrumental for a neon city drive, pulsing bass, arpeggiated synth, punchy electronic drums, spacious chords, short intro, strong central groove, definite ending.” Then use the documented BPM and structure controls to refine the brief. The listings establish that those controls exist, but they do not document exact synthwave presets, specific instruments, a guaranteed output tempo, or a loop setting. Confirm those details in the generated track and current interface before relying on them.
Rank #2
- Compact and portable design with a built-in speaker for on-the-go music creation
- Features an Electribe-style 16-step sequencer for intuitive and flexible music programming
- Includes eight memory patches for storing custom sequences and patterns
- SYNC In and Out for clock synchronization with other Volca series instruments

Loudly offers a free plan, but free generated tracks are limited to 30 seconds. Its generator page says the music is royalty-free and includes a commercial license; the directory also says paid licensing rights depend on plan terms. Check the current plan terms and intended-use coverage before publishing or monetizing a track. The product is web-based, so use it through a browser on your phone; native desktop software is not listed.

2. AI Game Music Generator — Best For Trying A Synthwave Example
AI Game Music Generator earns a place because its site shows a synthwave track labeled 2:58, an actual genre-specific example rather than a broad promise alone. It says users can preview, fine-tune, and download tracks as MP3 or WAV, with a commercial license ready to ship. For a 120 BPM project, it may be worth trying when you want to hear a synthwave direction and adjust the generated track, but the supplied information does not establish a tempo entry or 120 BPM setting.
Rank #3
- EXPERIMENTAL HYBRID SYNTH: MicroFreak packs so much into such a compact instrument, you'll wonder how we did it. From physical modeling to wavetable synthesis, it features 17 awesome paraphonic oscillator modes, including 7 bespoke Arturia engines, 7 modes from Mutable Instruments, and 3 modes designed with Noise Engineering. Its digital engines are combined with a lush-sounding resonant analog filter for true hybrid sound design.
- UNIQUE KEYBOARD: It isn’t really even a keyboard, it’s a super-flat PCB with no moving parts. The 25-key printed circuit board not only tracks the notes you play with lightning-speed, but can also detect pressure or aftertouch on each note individually.
- INNOVATIVE FEATURES: Record up to four automations, edit notes per step, or use the innovative Spice and Dice sequencer functions to find happy accidents. Add randomization to create evolving, original patterns, and virtually rewire and reconfigure its signal chain and controls with the 5x7 modulation matrix, with user-assignable destinations for totally unique sounds.
- MULTIPLE MODES: Easily switched and directly controlled with the 4 dedicated knobs in the Digital Oscillator section, MicroFreak has been constantly evolving. It now contains 17 oscillator types, covering a multitude of timbral flavors from sweet to savage: Vocoder, Noise, Superwave, Harmo, Karplus Str., Wavetable, BasicWaves, with many more.
- AMAZING CONNECTIVITY: It features CV outputs, letting you send pitch, gate, and pressure signals to any outboard or modular synth that’s CV/Gate compatible. You can also hook it up to your DAW via USB, or use the included MIDI break-out cables.
A practical prompt to try is: “Synthwave instrumental at 120 BPM for a retro arcade level, steady dance pulse, driving bass, bright repeating synth figure, dramatic chord lift, energetic but unobtrusive background.” The site’s documented fine-tuning feature may help shape the result, but the available details do not identify which properties can be fine-tuned. Do not assume it can lock the track to 120 BPM: preview the result and verify the tempo with a suitable audio or production tool before syncing it to gameplay or video.
The free plan includes five AI songs, and signup includes 60 credits for those tracks. The site also lists 30 AI music tracks per month for 360 credits; check the vendor’s site for the plan and terms attached to that allowance. Songs cannot be kept private, and the site says songs are owned by aigamemusic. It also advertises a commercial license. Before using a song in a public or commercial project, review the platform’s current terms and consider whether public availability and the stated ownership fit your use.

Choose By How Strict The Tempo Is
If your project needs a measured 120 BPM for cuts, animation, or a repeating gameplay rhythm, start with Loudly because BPM refinement is specifically documented. If you are exploring synthwave ideas and are comfortable checking the tempo after generation, the second option provides a genre example and previewing and fine-tuning. Neither listing establishes that every generated track will maintain an exact tempo throughout; listen and verify the audio before synchronizing other work to it.
Recommended Free Tools
For a phone-first workflow, keep the prompt short enough to edit comfortably and save the exact wording you used. Begin with genre, tempo, and the central groove; add the bass, drums, and synth texture next; then describe the arrangement and ending. Generate or preview, check whether the beat feels steady, and adjust one instruction at a time. This makes it easier to tell whether a change to the mood or arrangement helped without losing the core 120 BPM brief.
Best Value
- Discover endless sweet spots between sonic universes and tear up the rulebook with an addictive hybrid synthesizer that invites you to play without consequences.
Rights And Publishing Checks
Licensing descriptions are not interchangeable with ownership or privacy terms. Loudly’s generator page states a commercial license and royalty-free music, while its directory entry says paid licensing rights depend on plan terms. AI Game Music Generator advertises a commercial license, says its songs are owned by aigamemusic, and says songs cannot be kept private. Review each service’s current terms for the particular release, video, game, or monetized use before publishing. If your prompt or project includes a real person’s voice, recognizable recording, or other material you did not create, make sure you have consent and follow the platform’s terms; the supplied product details do not establish voice cloning or sample-clearance features.
Quick Recap
Quick Workflow For A 120 BPM Brief
- Write the target first: synthwave, instrumental or vocal, and 120 BPM.
- Add a small set of audible details, such as a pulsing bass, arpeggiated synth, steady kick and snare, and a wide lead melody.
- Describe the use and arrangement, such as a night-drive video with a short intro and clean ending, or background music for an arcade level.
- Use Loudly’s documented BPM and structure controls when available; with AI Game Music Generator, preview and fine-tune, then independently verify the tempo.
- Listen through the beginning, middle, and ending for tempo drift, unwanted vocals, abrupt transitions, and a finish that suits the project.
- Check the current license and privacy terms before sharing or monetizing the final track.
