Version 1.4.0 brings (experimental) MIDI parameter mapping and automation, a new Signal Analyzer utility, broader audio format support, and a big round of Jam and UI improvements.

I don't have a decent midi controller so midi mapping feedback is especially appreciated!

Highlights

• MIDI parameter mapping and automation workflows, plus direct MIDI setlist bank selection.
• macOS version is now signed & notarized which removes security warnings when installing.
• New Signal Analyzer utility effect with LUFS loudness measurement and bark band perceptual analysis.
• IR Cab, riff import, and demo audio now support AIFF/AIFC and MP3 in addition to WAV.
• New folder browser with favorites, tagging, and filter-by-tag support for local resources.
• Jam tab is now enabled on macOS and Linux with substantial layout and interaction improvements.

MIDI & Automation

• Added MIDI parameter mapping and automation workflows.
• Added direct MIDI setlist bank selection, plus bank up/down behavior fixes.
• The UI now updates parameter values immediately when controls change via MIDI.

DSP & Audio

• Revised NAM calibration support for chained NAMs.
• Reviewed NAM calibration handling for stereo vs. mono signal paths and added a post high-pass DC blocker (5 Hz) to match the reference gateway.
• Added low-latency mode for IR Cab and IR Reverb, with low latency now used by default for IR Reverb.
• IR Reverb output balancing now uses L2-normalized gain for more consistent loudness.
• Fixed EQ artifacting when adjusting EQ parameters.
• Improved mono ping-pong delay behavior to preserve a correct mono main path.
• Fixed blend effect behavior and improved live model blend preview.

Audio Import & Formats

• IR Cab loading, riff import, and demo audio now support AIFF/AIFC and MP3 files in addition to WAV, via a new shared multi-format audio decoder.

Signal Analyzer

• Added a new Signal Analyzer utility effect for real-time signal level diagnostics.
• Added LUFS loudness measurements to the Signal Analyzer.
• Added bark band perceptual analysis to the Signal Analyzer.
• Signal Analyzer now supports mono/stereo input modes.

Presets, Library & Resources

• Added a new folder browser with favorites and preview support for local resources.
• Added tagging and filter-by-tag support to the resource and folder browser, plus general UI polish.
• Added an architecture filter and improved navigation for NAM models in the resource browser.
• Added prev/next selectors for stepping through resources without leaving the browser.
• Added a calibration indicator to show when a NAM model includes calibration data.
• Preset import now creates the destination folder when needed.
• Fixed "Save New Preset" flow where a newly created preset could be empty.
• Added library resource delete support.
• Fixed Tone3000 BYOK loading/authorization flow and added favourites support in BYOK mode.
• Improved startup and browsing performance by optimizing resource loading and deferring heavy tone/jam loads at startup.

Jam, UI & UX

• Jam tab is now enabled with substantial layout and interaction improvements.
• Fixed Jam video playback integration issues including CORS handling, scrolling, touch drag, and WebKit docking behavior.
• Migrated UI icons to SVG assets for cleaner and more consistent cross-platform rendering.
• Expanded and consolidated theme/layout work (including light/classic refinements) and improved general UI consistency.
• Reworked UI assembly/components architecture for a more maintainable and flexible interface foundation.

Platform & Packaging

• Windows installer now allows choosing a custom install location.
• macOS installer package is now signed and notarized

Stability & Internal Improvements

• Reduced unnecessary UI updates caused by DSP performance stats.
• Fixed live DSP stats updates.

Hi,

I've added a discord server for Soundshed Guitar:

Note that I won't be around on it that often so it's more to help the community help each other, and gather common feedback etc.

Version 1.3.0 delivers signal chain performance upgrades, improved NAM level behavior, and a broad UI and workflow refresh.

Highlights

• Reworked NAM processing to better match the reference implementation, including resampling performance fixes.
• Faster preset switching with background preset loading and safer signal chain pause/resume during load.
• New parallel effects-chain execution pipeline with adaptive workload balancing for better multi-core CPU efficiency.
• IR Cab now supports pan or L/R split for true stereo cabinet placement.
• Tone sharing and browser workflow has been overhauled for cleaner navigation and sharing behavior.

Plus many more improvements and bug fixes.

Soundshed Guitar is a free guitar and bass multi-fx plugin/standalone app with community presets.

Version 1.2.0 Is out now at https://guitar.soundshed.com

Highlights

• Support for NAM A2 architecture, including adjustable NAM processing quality in Settings > DSP Performance.
• Updated Tone 3000 integration, now defaulting to A2 NAM models for new resources.
• Mono/stereo path DSP optimizations.
• Combined performance work reduces single-thread/core DSP usage from about 30% to 5-10% when using mono path with NAM A2 in slim (min) quality mode.
• CLAP plugin is now available on all platforms.

Note:

• requires AVX2 or higher enabled CPUs for SIMD. These are generally late 2015 onwards.
• if you get glitchy performance make sure you are running at 48Khz sample rate. Other sample rates (even 44Khz) require resampling to match the NAM models which are generally 48Khz.
