# Create Music Parameter Audit Report

## Executive Summary

This audit identifies which parameters from Advanced and Pro modes are actually being used in music generation and which are being ignored.

## ✅ FIXES IMPLEMENTED

**Date**: Implementation completed

### Advanced Mode Fixes
- ✅ Added prompt enhancement logic to incorporate all Advanced Mode parameters (tempo, key, scale, timeSignature, energy, excitement, mood, language, voiceType, useCase, instruments) into the prompt
- ✅ Advanced Mode now works similarly to Pro Mode - all form fields are incorporated into the final prompt sent to the API
- ✅ **Result**: 18 out of 19 parameters now working (tags is metadata-only, not sent to API)

### Pro Mode Fixes
- ✅ Added production/mixing parameters (reverb, compression, stereo width, bass/mid/treble levels) to prompt enhancement
- ✅ All sliders now convert their values to natural language descriptions and are added to the prompt
- ✅ Updated `$hasProSettings` check to include production parameters
- ✅ **Result**: 39 out of 40 parameters now working (only proVariations not implemented, may not be API-supported)

## Critical Finding: Advanced Mode Parameters Are NOT Being Used

**All Advanced Mode form fields are read from POST but NONE are incorporated into the prompt sent to the API.**

## Root Cause Analysis

### Advanced Mode Issues

1. ✅ **FIXED: Prompt enhancement for Advanced Mode**: Added logic (lines 530-592) to incorporate Advanced Mode form fields (tempo, key, scale, energy, excitement, mood, language, voiceType, useCase, instruments) into the prompt.

2. ✅ **FIXED: Missing logic**: Added `$hasAdvancedSettings` check and `$advancedSettingsParts` array (similar to Pro Mode) to build and append settings to the prompt.

3. ✅ **FIXED: Location**: Added Advanced Mode prompt enhancement code before Pro Mode section (lines 530-592).

### Pro Mode Issues

1. ✅ **FIXED: Production/Mixing parameters**: Added reverb, compression, stereo width, bass/mid/treble levels to `$proSettingsParts` array (after line 836). These are now converted to natural language descriptions and added to the prompt.

2. **Variations parameter unused**: `proVariations` is read but never used anywhere in the code. This may be intentional if API.box doesn't support variations.

---

## Code Locations

### Advanced Mode Parameters Read (but not used)
- Lines 136-153: All advanced mode parameters are read from POST
- **Missing**: Code to incorporate these into the prompt

### Pro Mode Parameters - Working
- Lines 594-844: Pro settings are incorporated into prompt via `$proSettingsParts` array
- Lines 838-843: Settings are appended to `$finalPrompt`

### Pro Mode Parameters - NOT Working
- Lines 174-179: Production parameters are read but never added to `$proSettingsParts`
- Line 158: `proVariations` is read but never used

---

## Recommendations

### ✅ COMPLETED: Priority 1: Fix Advanced Mode
1. ✅ Added logic similar to Pro Mode (lines 530-592) to incorporate Advanced Mode parameters into the prompt
2. ✅ Created an `$advancedSettingsParts` array to build settings text
3. ✅ Append advanced settings to `$finalPrompt` when Advanced Mode is active (when `advancedPrompt` is provided)

### ✅ COMPLETED: Priority 2: Fix Pro Mode Production Parameters
1. ✅ Added reverb, compression, stereo width to `$proSettingsParts` array (after line 836)
2. ✅ Added bass/mid/treble levels to `$proSettingsParts` array
3. ✅ Formatted these as natural language (e.g., "Heavy reverb", "Moderate compression")
4. ✅ Updated `$hasProSettings` check to include production parameters

### Priority 3: Fix Variations (Still TODO)
1. Either implement variations functionality or remove the field from the UI
2. Note: API.box may not support variations parameter - needs verification

## Files to Modify

1. **`create_music.php`** (Primary file)
   - Add Advanced Mode prompt enhancement (after line 592, before Pro Mode section)
   - Add Pro Mode production parameters to `$proSettingsParts` (around line 750)

2. **`includes/create_music_modal.php`** (Optional)
   - Consider removing or documenting non-functional fields
   - Add tooltips explaining which parameters are working

---

## Notes

- All parameters are being saved to the `metadata` JSON field in the database (lines 1039-1101), so they're preserved but not used for generation.
- The API.box API only accepts: `prompt`, `model`, `style`, `title`, `customMode`, `instrumental`, `duration`, `callBackUrl` (line 1377). All other parameters must be incorporated into the `prompt` text itself.
- The current implementation correctly sends only supported API parameters (lines 1377-1405).
