Beads Reverb

The reverb from Mutable Instruments Beads as a standalone stereo reverb for the Aurora, with all four of Beads' quality settings. Every knob and CV input does something, and it adds a freeze mode.

Four qualities

On Beads, the quality button changes the converter's sample rate, the bit depth, the input saturation and the reverb's tuning. This firmware does all of that. The 32 kHz and 24 kHz modes run the reverb at that rate inside the firmware, so their delay lines get longer and darker, as they do on Beads.

Wow and flutter

Measured decay

Level of a fully wet impulse response, measured second by second in an offline test of this firmware with Time at 70% and the other knobs at noon. Anything quieter than −60 dB is drawn at the bottom line.

Knobs

At noon, Reflect, Atmosphere and Blur match Beads' own settings, so you start from the original sound and can push past it either way.

Time

Decay

From a short room to a long wash. The range depends on the quality, as it does on Beads.

Reflect

Diffusion

Turn it left for separate, grainy echoes, or right for a dense, smooth cloud. Noon is Beads' setting.

Atmosphere

Damping

Left is darker, right is brighter. Noon is the damping Beads uses for the current quality.

Blur

Modulation

How much the delay lines move, which smears and chorus-es the tail. Fully left is static, noon is Beads, and fully right is twice that.

Warp

Wow & flutter

Tape pitch wobble, in any quality. Fully left is off, noon is Scorched cassette's depth, and fully right is three times that.

Mix

Dry / wet

Uses Beads' own curves for the reverb send and the dry/wet crossfade.

Each CV input adds to its knob. The sum is clamped to the knob's range.

Buttons, gates and LEDs

Reverse button · Reverse gate

Change quality

Goes to the next quality. Hold Shift and press Reverse to go back one. The sound fades out and back in over about 10 ms, and the reverb tail is cleared.

Freeze button · Freeze gate

Freeze

Turns infinite reverb on and off. The input is cut and the current tail holds, fading only very slowly (about 3 dB over 8 seconds). The dry signal still passes through.

LEDs 1–4 show the current quality, and the Reverse LED lights in Beads' colour for that quality. The Freeze LED is lit while freeze is on.

Installing

  1. Download BeadsReverb.bin using the button at the top of this page.
  2. Copy it to the top level of a USB drive. That should be the only .bin file there; others can stay inside folders.
  3. With the Aurora powered off, plug the drive into its USB port.
  4. Power on. The Aurora loads the firmware from the drive.

To go back to the stock firmware, load the official .bin from the Aurora product page the same way.
