Pocket additional permissions#

Pending legal review. These permissions are in effect for every copy of Pocket that includes this file. An attorney hasn't reviewed their wording yet, and a later version may clarify it. A copy of Pocket you've already received keeps the permissions it came with.

These are additional permissions under section 7 of the GNU Affero General Public License, version 3 (the "License"), granted by Ryan Palermo, the copyright holder of Pocket. They apply to Pocket's own material. They don't change the license of the third-party material listed in NOTICE.

As section 7 of the License allows, if you modify Pocket you may remove these permissions from your copy. Licensing explains in plain language what they mean for musicians; this file is the version that counts.

Definitions#

"Output" means files produced by running Pocket, such as audio, MIDI, analysis results, reports, receipts, manifests, lineage records and Live Sets.

"Pocket Device Files" means the Max for Live device sources in src/pocket_music/devices/ and the files Pocket's device builders produce from them, such as Baste.amxd, Native MIDI.amxd and Native MIDI Writer.amxd together with their .maxpat, .js and manifest.json files.

"Musical Project" means a collection of material made for creating, performing, practicing, recording or sharing music, such as an Ableton Live Set and its project folder, or a trial, candidate or promoted project made with Pocket. A software product is not a Musical Project.

1. Output#

The License covers Pocket itself, not what you make with it. To the extent that Output contains material from Pocket, such as fixed text, schema identifiers or settings that Pocket writes into receipts, reports, MIDI files or Live Sets, you may convey that Output under terms of your choice, without the conditions of the License.

This permission doesn't extend to Pocket Device Files, which section 2 covers, or to any other part of Pocket's source code.

2. Unmodified device files in a Musical Project#

You may convey unmodified Pocket Device Files as part of a Musical Project under terms of your choice, without the conditions of the License. This applies whether the files were placed in the project by Pocket (for example by its device builders, Stitch or Pipette), by Ableton Live (for example by Collect All and Save, or by freezing a device), or by you.

This permission doesn't apply to modified Pocket Device Files, or to Pocket Device Files conveyed on their own or as part of a software product. Those remain under the License.

3. Ableton Live and Max#

If you modify Pocket, or any covered work, by linking or combining it with Ableton Live, Max, Max for Live or Node for Max (or a modified version of those programs), including their libraries such as the Live API and max-api, containing parts covered by the terms of their own licenses, the licensors of Pocket grant you additional permission to convey the resulting work.

This section is not part of the permissions.

  • Section 3 adapts the Free Software Foundation's template for a GPLv3 section 7 linking exception to name Pocket's host programs. Confirm it's needed and sufficient for devices that run inside a proprietary host.
  • Sections 1 and 2 are new wording in the spirit of the Bison exception. Confirm that "Musical Project" and "unmodified" are tight enough that a competitor can't use section 2 to ship modified or standalone devices in a closed product, and loose enough that musicians sharing Live Sets never need to think about the License.
  • Confirm the effect of publishing these permissions before review, and how a later revision applies to copies already distributed.
  • Package metadata declares AGPL-3.0-only AND Apache-2.0, because Python packaging tools don't accept a custom SPDX exception identifier. Confirm that this is acceptable.
