MACE v1.3.1 – Critical Update

This update fixes a few critical errors and adds additional enhancements to the 1.3.0 release of MACE. This is the full installer and current version.

Critical Bugs:

  • Release Envelope Fix: The release envelope was inadvertently disabled in the 1.3.0 release. This patch restores its functionality.
  • Clicking/Popping Fix: A bug that caused clicking or popping sounds during playback has been addressed, ensuring smoother audio playback.

Enhancements:

  • Settings.cfg File Moved: (WINDOWS ONLY) The settings file has been relocated to the MACE user’s documents folder as some users were reporting access issues in its previous location.
  • Force CPU Mode: A new setting allows users to force MACE to run in CPU mode, which can be useful for troubleshooting or performance tuning.

MACE v1.3.0 Update ✨

MACE Version 1.3.0 is the biggest leap forward yet in MACE’s evolution. We’ve cracked open the next frontier: direct text-to-audio generation inside your DAW — powered by a new Prompt Engine, GPU acceleration across platforms, and a complete rework of how samples are managed and stored.
This update transforms MACE into not just a generative sampler — but a next level sound design interface for the modern producer. The Prompt Engine runs natively, on your own machine! No subscriptions, tokens, or cloud based processing or wait times.

Quick Look At New Features👇

🎙️ Prompt-to-Audio Generation – Powered by Stability AI™

You can now generate entirely new sounds from text prompts using the all-new Prompt Engine. Up to 11-second, high quality, stereo samples are generated locally on your machine — no cloud or tokens required. This utilizes diffusion models by Stability AI™.

Note: Legacy generative models have been dubbed “Fixed Models” but still behave as before!

🧠Prompt Editor Overlay

A powerful new Prompt Editor for writing and refining your sound ideas. Tag prompts with format, BPM, duration, diffusion meta parameters, etc. for crafting a generation! You can also export them into your personal Prompt Library for reuse.

🗃️ Prompt Library Integration

The browser now includes curated prompt categories like Drum Loops, FX, Bass Shots, Vocals, and more. Load presets instantly without typing anything.

⚡ GPU Acceleration Across Platforms

Windows: Supports GPU generation with DirectML (no CUDA required). Works on AMD, NVIDIA, and Intel GPUs. No setup required. MACE will auto-detect your hardware and fallback to just CPU mode if needed.

macOS: GPU generation powered by CoreML — optimized for M1–M4 chips. Intel chips are still compatible, but much slower.

🧱 Fixed Models (Legacy Support)

Legacy generators are now labeled Fixed Models in the Model Browser. They don’t support prompts but are still:

  • Fast
  • Light on system resources
  • Great for one-shots and creative grains

These models work even on machines that can’t run the Prompt Engine. Ideal for quick stabs and percussion!

🕘 Prompt Session History

MACE keeps track of every prompt you’ve used during your current session. The Prompt Session History lets you revisit, reuse, and tweak previous prompts without starting from scratch — perfect for rapid iteration or recovering that “happy accident.”

🔍 Advanced Waveform Viewer

The Advanced Waveform Viewer in MACE 1.3.0 has been overhauled for precision, performance, and clarity. Whether you’re fine-tuning loops, editing one-shots, or inspecting textures, this new viewer gives you detailed control and visual feedback.

Key Features:

  • High-Performance Zoom & Pan
    Smoothly zoom in on microdetails or zoom out to view the full waveform. Navigate with ease, even on long files.
  • Beat Grid Overlay
    View your waveform against a live beat grid synced to the host BPM. Ideal for aligning loops and rhythms.
  • Loop Marker Snapped Control
    Adjust loop in/out points directly on the waveform with snapping behavior that adapts to your snap mode (Beat / Fine / Free).

🧲 Beat Snapping Modes

Precision meets flexibility with the new Beat Snapping system in the Sample View. Toggle between Beat Snap, Fine Snap, and No Snap modes to control how your loop markers behave.

  • Beat Snap locks markers to the beat grid for perfect timing
  • Fine Snap allows micro-adjustments while still giving subtle grid guidance
  • No Snap gives you complete freehand control

Snapping is automatically enabled after generation depending on the loop’s length — but you can always override it from the Sample View toolbar.

Bonus: use hotkeys (see below) for quickly switching snap modes while dragging markers.

📂 Generation Cache System

All generated audio is now stored to disk, not RAM — allowing for long files and smoother performance. Generative applications produce a lot of data, quickly, and this is a start to a much broader generation management system.

🛡️ Session Protection

When you save a project, all related generations are auto-marked as “Protected” to prevent accidental deletion when wiping the cache. This automatically happens when you save a project with MACE.

🧹 Cache Wipe Utility

Clean up your generation folder with a single click. Any files not tied to a session or marked “protected” are safely removed to the operating system’s Recycle Bin for you to purge. Backup is recommended before cleaning the cache.

Note: When you drag a sample out, it is safely exported to the Sample Renders directory set in your settings — this is not effected by a cache wipe.

📁 Consolidate Active Cells to Folder

Choose a folder on your disk and MACE will copy all currently active samples there — and update references automatically. Perfect for safeguarding important sessions or moving projects across machines.

Enhancements

⚙️ “Fixed Models” Label for Legacy Generators
Legacy generative models are now labeled Fixed Models in the browser. They still behave just like before — ideal for quick, reliable one-shots without prompt editing.

🎛️ Advanced Waveform Viewer
Zoom, pan, and inspect your generated audio with a vastly improved viewer for better precision editing.

🔄 Auto Beat Sync + Manual Resync Button
Generated loops are now automatically snapped closer to your host’s tempo. You can also manually resync any loop post-generation.

📏 Time Stretch Update
Audio length is now capped to 30 seconds to avoid overload — ensuring fast, manageable generations.

🎚️ Drag to Export with Resampling
Dragging out a sample now automatically resamples it to match its playback settings. Hold Shift to export the original, untouched file.

⚙️ Regen Button Exposure for Automation
New option in the Settings Panel to expose regeneration buttons to your DAW’s automation lanes. When selected, your DAW will pickup the regeneration. This prevented a major bug in which Ableton was dis-engaging its automation automatically

⛓️ Automation & MIDI Trigger Support (Even When UI is Closed)
Prompt regeneration can now be triggered via automation or MIDI regardless of whether the UI is open — perfect for live sets or hands-free workflows.

Bugs Addressed

  • Major Fix: Playback engine had issues that introduced subtle audible clicks when rapidly firing notes on samples
  • Major Fix: Playback engine had issues in which looping in ping-pong audibly was glitching when voices were greater than 1
  • Fixed issue where regeneration wouldn’t trigger if the UI was closed.
  • Fixed issue where a feedback loop of automated regen parameters was causing Ableton to disable automation on the fly.
  • Fixed CELL_LOOP parameter firing unintentionally after each generation.
  • Plugin state now correctly saves associated WAV files with proper flags.
  • Fixed an issue where Settings for paths now persist correctly and no longer revert to defaults on plugin close in some cases.
  • Various optimizations and crash fixes.

New Hot Key Functions and Misc

🎛️ Shift Drag of Prompt Models into a cell will pull up the Prompt Editor first

🎛️ Right clicking Prompt Models in browser allows multiple options for managing the Prompt such as show in editor, show on disk, etc.
