Moises Try it →Watch full video →Andrew Clarke · Aug 2025

Demo summary

The user demonstrates the 'Custom' bass generation by typing a text description and adjusting harmonic and conditioning strictness settings to generate a bass track.

Step-by-step

Click on Bass in the generation menu
Select the Custom tab
Type a text description of the desired bass line into the prompt field
Toggle track visibility to determine which instruments the AI uses for context
Adjust the Harmonic Strictness slider to control melodic complexity
Adjust the Conditioning Strictness slider
Click the generate button

Options

Mute specific tracks (like drums) to force the AI to focus its context on fewer instruments
Choose from pre-set AI styles instead of using Custom text prompts

Tips

Keep the drums active if you want the generated bass to lock in with the rhythm
Increase harmonic strictness if you want the bass to follow the chords closely without adding 'crazy' notes
Muting tracks gives the AI a smaller context which can help it focus more on a specific instrument like guitar
