Positive Grid builds a practice bandmate into an amp, not a plugin

The audio task

A guitarist practicing alone wants a live bass-and-drums backing that reacts to their own playing in real time, without programming a drum machine or hunting for a matching backing track online. Positive Grid built this directly into hardware: its Spark amplifier line pairs with a companion app to generate that backing on the fly, rather than shipping it as a separate plugin or subscription app.

What the documents show

Positive Grid's own Spark product page, as retrieved on 16 September 2026, describes a feature called Smart Jam Live in these terms: "Simply start to play and the Spark amp and app work together to learn your style and feel. Then Spark generates authentic bass and drums to accompany you in real time. It's a smart virtual band that's always ready to jam!" The companion Spark App page describes the same feature as letting a player "select a virtual bandmate and start playing," after which the app will "generate authentic drum and bass tracks to accompany and adapt to your unique playing style—all in real time," and names a specific bandmate, "Jarvis," described as "an AI-powered rock drummer who listens to how you play and provides you with real-time feedback based on your dynamics."

Rights status

Neither page reviewed here addresses ownership, licensing, or commercial-release rights for audio captured while using Smart Jam; both frame the feature entirely around live practice and jamming, not around producing a finished, distributable recording. No statement on these pages says a recording made while Smart Jam is playing along is cleared for release, nor does either page prohibit it — the question is simply not addressed in the product material reviewed.

What to check before you use it

This is an editorial checklist. Before releasing any recording that includes Smart Jam's generated bass and drums, ask Positive Grid directly for a written statement on commercial-use rights, since the product pages describe the feature only as a practice tool. Check the current Spark app's terms of service, separate from the hardware product page, for any clause addressing ownership of AI-generated accompaniment.

• Does Positive Grid's terms of service say anything about ownership of audio generated by Smart Jam or the Jarvis bandmate?
• Are you planning to release a recording that includes this generated backing, rather than using it only for private practice?
• Has Positive Grid published separate guidance for commercial use since this page was last retrieved?

Smart Jam is a clear example of an AI feature marketed for a practice use case where the underlying rights question for recorded, released output is simply left open by the vendor's own materials.
