Responsive accompaniment
Listens before it plays
Rainey Bass follows your timing, harmony, and dynamics in real time, leaving space when the song needs it and leaning in when the pocket opens.
AI session bassist

The instrument
Built around musical conversation.
Not a loop library and not a random note generator. Rainey Bass is a focused accompanist designed to react as the performance changes.
Discography-specific training
One focused musical vocabulary
The model is trained exclusively on Chuck Rainey’s discography—not a generic blend of unrelated bass styles—so its musical point of view stays specific.
Fast creative iteration
