NeoBleeper 1.4.2 Beta

NeoBleeper v1.4.2 Beta (February 2026 Preview)

This release fixes a critical bug in the note replacement system and improves the MIDI file player to reduce audio artifacts. The changes ensure that both note and length replacements work correctly when applied simultaneously, and deliver smoother playback with fewer crackling sounds and inconsistencies.

---

🔧 Changes

• Bug fix in replacing note with length replace

  • Fixed the bug that caused length not to be replaced when note and length were replaced at the same time.

• MIDI file player improvements

  • Improved playback engine to reduce crackling sounds and inconsistencies.

---

✅ Result

• Note replacement system now correctly handles simultaneous note and length replacements.
• MIDI file playback is smoother with reduced audio artifacts and better consistency.

NeoBleeper 1.4.1 Beta

NeoBleeper v1.4.1 Beta (February 2026 Preview)

This release fixes key inefficiencies in Synchronized Play and Create Music with AI, and adds full percussion-channel handling (Channel 10). The changes eliminate overlapping/mistimed synchronized starts, makes sanitization of malformed AI-generated notes (e.g. A#Whole) more efficiently, and list Channel 10 as percussion channel so the instrument selector is disabled for them.

---

🔧 Changes

• Synchronized Play — prevent overlapping / wrong-timed starts

• Physically prevent initiating "Start waiting" from the Synchronized Play dialog while local playback is active (they will show error if tryed to wait id list is empty or music is already playing)

• UTC-based time now used to prevent time zone-related issues

• Create Music with AI — more efficient sanitization for malformed tokens (example: A#Whole)

  • Parser now fixed some invalid notes (e.g., A#Whole) more efficiently.

• MIDI / Percussion handling — Channel 10 detection & UI behavior

• 

  

  • Label Channel 10 as "Channel 10 (Percussion)".
  • When Channel 10 is selected, disable (gray out) the Instrument selector and log to both debugging console and DebugLog.txt: "Percussion or sound effects channel selected; instrument selection disabled."
  • Playback engine respects percussion semantics (do not apply melodic program changes to percussion channel).

---

✅ Result

• Synchronized playback no longer suffers from race conditions that caused mistimed starts or overlapping audio.
• AI-generated music imports more reliably (fewer invalid notes) with visible correction summaries.
• Percussion channels behave correctly and users are prevented from selecting meaningless melodic instruments for Channel 10.

NeoBleeper 1.4.0 Beta

NeoBleeper v1.4.0 Beta (Early 2026 Preview)

This update focuses on UI spatial precision, audio hardware transparency, and structural diagnostics. We have refined the interface to handle Windows-specific rendering quirks and improved how the software reports NBPML errors generated by AI.

---

🚀 New Features & Improvements

NBPML Structural Diagnostic Viewer

The AI Generated NBPML Window has been upgraded from a simple error prompt to a diagnostic display. While the window remains read-only to preserve the raw output for troubleshooting, it now visually identifies exactly where the AI failed.

• Error Marking: If the AI produces invalid NBPML, the software now marks the specific broken tag that caused the validation failure.
• Transparency: Users can now see exactly which part of the generated document is malformed, providing clarity when a generation cannot be processed.

Redesigned GCode Creator

We have completely overhauled the Convert File to GCode interface for better usability and safer machine operation.

• Improved Layout: Streamlined the selection for Firmware (Marlin support), Note channels, and Axis mapping (X, Y, or Z).
• Safety Integration: Added clear mechanical damage warnings when using high-speed motor commands.
• Alternating Note Logic: New radio buttons allow users to toggle between sequential playback or odd/even column priority for complex patterns.

Updated System Speaker Status Messages

Based on testing with IBM PC Speaker-style hardware (physical magnets rather than piezo buzzers), we have updated the audio status messages to be more descriptive of hardware behavior.

• Unexpected Audio Feedback: During development on older laptop hardware, it was discovered that these speakers produce "popping" or "clicking" sounds during initialization rather than standard beeps.
• Clarified Warnings: The System Speaker Checker and System Speaker Awaker now include warnings about these clicking/popping sounds. This ensures users know the sound is a result of the chipset engaging and not a software malfunction.

---

🛠️ Bug Fixes

Disabling "Create beeps using sound device" Fix

• Inverted "Create beeps using sound device" Logic: Fixed a logic error where unchecking "Create beeps using sound device" was incorrectly handled as "Enabled" in the code when system speaker warnings are masked. This caused the engine to bypass the internal system speaker/physical buzzer.

Windows 10 Checkbox Layout Fix

We addressed a rendering bug in Windows 10 where text labels in checkboxes with icons would overflow their boundaries.

• The Fix: Added small, precise paddings to the internal sizes of these checkbox components. This ensures text remains properly contained and aligned with its associated icon, even at different system scaling levels.

NBPML Integrity & XML Stability

We have resolved the "Constant XML Error" loop and the accidental "breaking" of NBPML files in the Create Music with AI module.

• Accidental Breaks: Fixed a logic flaw where the engine would accidentally corrupt valid NBPML structure while attempting to sanitize AI hallucinations.
• Stability: Resolved persistent XML errors, ensuring the AI music creation process is significantly more resilient and consistent.

Localization Audit

• Duplicate Cleanup: Fixed an issue where localized strings were duplicated, missing or inaccurate in certain menus, which some of them are appearing as English in non-English languages.
• Consistency: Synced all localizations to ensure that new v1.4.0 features and hardware warnings are accurately described in all supported languages.

NeoBleeper 1.3.0 Beta

NeoBleeper v1.3.0 Beta (Final 2025 Release)

This update focuses on API stability and interface responsiveness to ensure a smoother experience as we wrap up the year.

🚀 New Features & Improvements

• "Create Music with AI" Character Limit: Added a 512-character limit to the "Create Music with AI" prompt field.

  • This prevents token excession errors or large input errors from the Google Gemini™ API and ensures the feature is used as intended without crashing or abusing the generation process.

• Enhanced NBPML Sanitization: Improved the "Create Music with AI" logic to automatically fix or remove orphaned tags, more broken structures, or more hallucinations in the generated NBPML document.

• Enhanced Connection Checks: Improved the connection checking logic of the "Create Music with AI" to preventing false positives that unfairly interrupting the AI music creation.

• Enhanced Infinite Loop Detector: improved the infinite loop detector logic of the "Create Music with AI to ensure detecting infinite loops more effectively.

🛠️ Bug Fixes

• UI Control Sync: Fixed a bug where certain common controls (buttons/toggles) would stay enabled or disabled incorrectly.

  • The Fix: Controls now accurately update their states the moment music or notes start or end, whether triggered manually by clicks or through the playback logic.

• NBPML Stability: Resolved remaining errors in "Create Music with AI" caused by malformed NBPML output from the AI.
