InsMelo AI Beat Maker is the clearest free starting point for bass-heavy beats: its listing specifically calls out trap with heavy bass and accepts text descriptions. Eleven Music is a good alternative for shaping a full track around deep bass, with free monthly credits and controls for genre, mood, instruments, and structure. Neither listing establishes dedicated 808 or sub-bass controls, so describe the sound you want and check the generated result before building a project around it.

Which Free Generator Fits Your Bass Track?
1. InsMelo AI Beat Maker: Best For A Bass-Forward Beat
InsMelo is the strongest match when the target is a beat rather than a complete vocal song. Its text-to-beat description specifically supports a prompt such as “aggressive drill beat with sliding bass,” and its trap example calls out heavy bass. You can also set genre, BPM, mood, and structure, which helps keep a low-end idea connected to a usable groove.
The product lists MP3, WAV, MIDI, and separate-stem exports, plus beat extension and track separation. Its free plan is limited to 3.9 credits; the listing does not establish how many generations or which export options that allowance covers. Confirm those details before planning a session around a particular file format. The product page describes beats as royalty-free and usable for commercial projects, while the pricing details say commercial rights depend on subscription or license terms. Check the applicable terms for the specific beat and plan.
2. Eleven Music: Best For Deep Bass In A Full Arrangement
Eleven Music suits a bass-led song where the low end needs to sit within a broader arrangement. Its examples include melodic trap and drill, as well as an alternative R&B track described with deep bass and electronic guitar. You can set genre, mood, instruments, and structure, then adjust elements without starting over.

How To Prompt For A Bass-Heavy Result
Start with the role of the bass, then describe the groove and surrounding elements. For InsMelo, enter a text description and set the available genre, BPM, mood, and structure controls. In Eleven Music, use its genre, mood, instrument, and structure controls to express the same musical direction.
