The script should have ignored it. + +### Root Cause +The v6 logic had a check to skip first/last tokens if they were pure numbers, but this check happened **after** the leading index was already mixed into the general token list. The timing was wrong: + +1. Filename: `67_HallOatsCombo_VP330_G3.wav` +2. Tokenization produces: `['67', 'halloatscombo', 'vp330', 'g3']` +3. BPM extraction checks position 0 (the '67') +4. The check `is_first_or_last = (i == 0 or i == original_length - 1)` **should** catch it +5. However, the check only worked when `t == num_str` (the whole token is just the number) +6. In this case, `tokens[0] = '67'` and it IS position 0, BUT... +7. The issue was that position-based checks weren't consistently applied before BPM range validation + +## The Fix in v7 + +### Key Changes + +1. **Early Index Detection** + - Before BPM extraction, identify the first token if it's purely numeric + - Mark this position as a "leading index" that should be excluded from BPM checks + +2. **Skip Leading Index in All BPM Passes** + - Pass 1 (explicit 'bpm' suffix): Skip the leading index position + - Pass 2 (pattern matching): Skip the leading index position + +3. **Improved Token Processing** + - Extract and remove the leading index early in `process_file()` + - This keeps the index separate for the final filename but prevents it from being mistaken for BPM + +### Code Example + +**OLD v6 Logic:** +```python +# Pass 2: Search within tokens +for i, t in enumerate(tokens): + # ... checks ... + is_first_or_last = (i == 0 or i == original_length - 1) + if is_first_or_last and t == num_str: + continue # Skip likely index +``` + +**Problem:** This check happened too late and inconsistently. + +**NEW v7 Logic:** +```python +# Early identification +leading_index = None +if len(tokens) > 0 and tokens[0].isdigit(): + val = int(tokens[0]) + if val < 1000: + leading_index = 0 # Mark position 0 as index + +# In both passes: +for i, t in enumerate(tokens): + if i == leading_index: + continue # Skip the identified leading index + # ... rest of BPM extraction logic ... +``` + +**Also in process_file():** +```python +# Extract index early +idx = None +if tokens and tokens[0].isdigit(): + idx = tokens[0] + tokens = tokens[1:] # Remove from processing tokens +``` + +## Additional Improvements in v7 + +### 1. Debug Mode +Added `--debug` flag that shows detailed BPM extraction logic: +``` +[BPM DEBUG] Input tokens: ['67', 'halloatscombo', 'vp330', 'g3'] +[BPM DEBUG] Token at position 0 ('67') identified as potential leading index +[BPM DEBUG] Skipping position 0 ('67') - identified as leading index +[BPM DEBUG] Final BPM: None +[BPM DEBUG] Remaining tokens: ['halloatscombo', 'vp330', 'g3'] +``` + +### 2. Better Machine Token Recognition +Added 'vp330' to the machine tokens list to prevent it from being parsed incorrectly. + +### 3. Improved Documentation +- Clearer inline comments explaining the logic +- Better function docstrings +- More detailed header documentation + +### 4. Code Organization +- More consistent variable naming +- Better separation of concerns (index extraction happens early) +- Clearer logic flow + +## Testing the Fix + +### Before (v6): +``` +67_HallOatsCombo_VP330_G3.wav → drumloop_halloatscombo_vp_67bpm_g_vp330_fmrs_03.wav + ^^^^^ + WRONG! +``` + +### After (v7): +``` +67_HallOatsCombo_VP330_G3.wav → drumloop_halloatscombo_vp_g_vp330_fmrs_67.wav + ^ ^^ + (no BPM) (index at end) +``` + +## Recommendations + +### For Production Use: +1. **Test with --debug flag first** to verify BPM extraction works correctly on your files +2. **Always run with --dry-run** (no --write flag) first to preview changes +3. **Check the CSV report** before applying changes for real +4. **Use --verbose** to see individual file transformations + +### For Edge Cases: +If you have files where legitimate BPM values appear at the start (e.g., `120bpm_DrumLoop.wav`), the script will still detect them correctly because: +- It looks for explicit 'bpm' suffix first +- It checks if the number is in the valid BPM range (40-300) +- It distinguishes between `120bpm` (BPM marker) and `120` (likely index) + +### Configuration: +You can customize behavior with a JSON config file: +```json +{ + "MACHINE_TOKENS": ["303", "808", "909", "vp330", "custom_machine"], + "TYPE_MAP": { + "customtype": "kick" + }, + "DESCRIPTOR_WHITELIST": ["custom", "descriptor"], + "PACK_DEFAULT_TYPE": { + "mypack": "instrument_synth" + } +} +``` + +Use with: `--config my_config.json` + +## Summary + +The v7 fix properly handles leading index numbers by: +1.
