Faderpunk 1.9.0 (2026-05-04)

The Superbooth 26 release

We're proud to present a beast of an update! Faderpunk v1.9.0 brings a ton of additions, fixes and general quality of life improvements. Let's go!!

First, we have 3 new apps: Random+, Clock Divider+, as well as our first community-submitted app by @rjsmith — FP-Grids, a Faderpunk port of Mutable Instruments Grids, including the drum and bass alternative mode by @thorinside.

MIDI gets a serious upgrade with 14-bit CC and NRPN support, and you can now also recall scenes via MIDI program change messages.

We now have Swing on the clock, applied to all clocked apps. App divisions are colour-coded: straight divisions show in blue, triplets in orange. The scene LED also flashes when the clock is running.

We've added a settings page when holding the scene button:

• LED brightness indicator (fader 1)

• Display scale and root note colour (top LED fader 4 & 5)

• Scales displayed as a keyboard on bottom LEDs

• Swing amount (top LED fader 15)

• Tempo (top LED fader 16)

• Buttons display last recalled/saved scene

On the configurator side, a lot of quality-of-life improvements landed:

• Detect connection status

• Update LED brightness, scale, root note and tempo params from device

• Duplicate apps in the layout editor

• Direct link to app manual in the Active App section

• Assign channel-related default CC numbers to avoid duplicates

Features

• Change scene via MIDI program change message (#459)

• Flash scene LED when clock is running (#471)

• Add 14-bit MIDI CC/NRPN support (#470)

• Add LED feedback for straight/triplet divisions (blue = straight, orange = triplet) (#481)

• Show info page on scene button press (#489)

  • Display scale as a keyboard on bottom LEDs

  • LED brightness indicator (fader 1)

  • Display scale and root note colour (top LED fader 4 & 5)

  • Swing amount (top LED fader 15)

  • Tempo (top LED fader 16)

  • Buttons display last recalled/saved scene

• Add Random+ app (#453)

• Add Clock Divider+ app (#456)

• Add FP-Grids app (#467)
