pipedal

PiPedal constrains configuration of audio buffers based on the minimum buffer size reported by audio devices. This code is currently incorrect. This release temporarily allows unconstrained selection of buffer sizes, in order to explore what kinds of buffer configurations should be offered to users in a subsequent release version. Please be aware that audio buffer configurations permitted in this release may not be permitted in subsequent versions of PiPedal.

This version fixes a significant and dangerous defect that may cause loss of presets, banks or configuration data if you remove power from your Raspberry Pi within up to five minutes of last saving data instead of performing an orderly shutdown or reboot. PiPedal users should upgrade immediately.

This release also fixes a significant performance issue with TooB Neural Amp Modeler.

Bug fixes:

• Explicitly sync files to disk immediately after saving, so that they won't be lost if power is removed from the Raspberry Pi.
• Fixes a significant performance issue with TooB Neural Amp Modeler.

This version focuses on fixes and improvements to TooB Neural Amp Modeler.
TooB NAM now uses about 20% less CPU, which can help enormously on Raspberry Pi 4.

You may need to change your audio buffers to prevent dropouts when using TooB Neural Amp Modeler. Setting your audio buffers to 32x4 seems to produce good results. You may also want experiment with 16x4 audio buffers. This seems to work, but it has had limited testing so far, so I can't say with any certainty whether it is stable for long-term use. 2-buffer audio settings should be avoided. As always, using your Pi for anything else at the same time you are using PiPedal will cause XRuns.

I would once again like to extend special thanks and acknowledgements to Steven Atkins for his outstanding work on the NeuralAmpModelerCore project on which TooB Neural Amp Modeler depends (as do almost all other Neural Amp Modeler plugins).

Bug fixes:

• The About page now displays the correct version.
• TooB NAM frequency response now displays correctly.
• TooB NAM no longer displays error messages when loading.
• Update Dialog has better layout on portrait phone displays.
• Prevent brief flashing of the Reload... button during the last phase of an update.

The .asc file is a gpg digital signature for the .deb file. You can verify the signature using the following command:

This version includes the following new features:

• Double-tap (or double-click) dial controls to reset them to default values.
• Update PiPedal to the latest version from within the PiPedal web UI or PiPedal client. PiPedal monitors the PiPedal github repository for new releases,
  and prompts you to update when new releases become available.
• Choose whether to monitor Release, Beta or Developer update streams, or disable update monitoring altogether.
• All PiPedal configuration settings now preserved when upgrading.
• Advanced configuration options are now stored in /var/pipedal/config/config.json so that they are preserved when upgrading.

Bug fixes:

• Fixed a bug which prevents the PiPedal UI from updating properly when using TooB Convolution Reverb and CabIR effects.
• Plugin controls now work when there's no audio device running, or when the audio device stops.
• Minor style and theming issues.

The .asc file is a gpg digital signature for the .deb file. You can verify the signature using the following command:

gpg --verify pipedal_1.2.44_arm64.deb.asc pipedal_1.2.44_arm64.deb

DO NOT USE

This is a test release used by the developer to test digital signing of update packages.

You can now upload new models into TooB ML. TooB ML models are compatible with models for the GuitarML Proteus plugin. Currently, the GuitarML Proteus model download pages are the best source for new models to use with TooB ML. To install
new models in TooB ML, follow these instructions:

• Download Proteus models from https://guitarml.com/tonelibrary/tonelib-pro.html to your local computer or Android
  device. TooB ML supports both Proteus .json models, and also allows you to install model collections contained in .zip files.
• Load the TooB ML plugin.
• click on the Model control.
• click on the Upload button in the lower left corner of the Model selection dialog.
• Upload the .json model file or .zip model collection that you downloaded from The GuitarML Tone Library.

• Dark Mode. Go to the settings menu to select the new Dark Mode theme.

Bug fixes:

• Plugin information is updated in the web app after reconnecting, in order to pick up new plugins that may have been detected while the web server was being restarted. You still need to restart the server to detect newly-installed LV2 plugins; but the web app will pick up changes without having to refresh the page.
