## B. Block Chain & Signal Flow

### B.1 Block Representation on Screen

Each block on the signal flow canvas displays:

- **Type icon** — Amp, Cab, Effect (with subcategory symbol), Split, Merge, FX Loop, Input, Output
- **Model name** — displayed within the block
- **Bypass status** — dimmed when bypassed; full color when active
- **Mono/Stereo/Legacy symbol** — shown next to model name in Inspector
- **Selected state** — thick white outline when selected
- **Link indicator** — gold link icon when Amp and Cab are linked
- **Clip indicator** — Input/Output blocks turn green (signal) / red (clipping)

### B.2 Block Selection and Editing Flow

1. **Tap block to select** → parameters appear in Inspector
2. **Tap selected block again** → Action Panel opens with commands:
   - Copy Block / Paste Block
   - Clear Block / Clear All Blocks
   - Assign to Switch (Bypass, MIDI Note, or CC)
   - User Default / Factory Default
   - Add to Favorites
   - Snapshot Bypass toggle
3. **Turn Knobs 1-8** → adjust parameters in Inspector
4. **Tap parameter** → Parameter Panel with slider, numeric entry, Min/Max nodes, Learn Controller, Clear Controllers, Snapshot Ctrl toggle
5. **Tap Focus View button** → opens block-specific Focus View
6. **Tap Bypass** → bypass/enable block
7. **Tap model name** → opens Model List to change model
8. **Drag block** → reposition on path or move to different path

### B.3 Signal Path Routing

**Path Architecture:**
- 4 stereo paths: Path 1A, 1B, 2A, 2B
- Each path holds up to 12 blocks
- 48 total block capacity (DSP permitting)
- Each path is stereo (left + right channels)

**Serial (Single Path):**
- Simple signal flow Input → Blocks → Output
- Up to 12 blocks on one path

**Parallel (Split/Merge):**
- Split block divides signal into Path A (upper) and Path B (lower)
- Merge block rejoins Path B into Path A
- Split types:
  - **Split > Y**: Stereosignal split evenly; Balance A/B for pan
  - **Split > A/B**: Route all signal to A or B; assignable to footswitch for A/B toggle
  - **Split > Crossover**: Split by frequency (high to A, low to B)
  - **Split > Dynamic**: Split by input level/playing dynamics (soft → A, loud → B)
- Merge > Mixer: A Level, A Pan, B Level, B Pan, B Polarity, Level

**Serial Path Extension (Super Serial):**
- Route Path 1 Output to Path 2A Input
- Creates contiguous serial path with up to 24+ block locations

**Independent Paths:**
- Drag both Split and Merge to Path B → creates independent Path B with its own Input and Output
- Each Input can use different source (Instrument, Mic, Return, USB, S/PDIF)
- Each Output can route to different destination

### B.4 Dynamic DSP Behavior

- **DSP per path**: Path 1 and Path 2 each have independent DSP
- **Block limits:**
  - Amp/Preamp: max 4 per preset (2 per path)
  - Cab: max 8 per preset (4 per path), 2 slots per Cab block
  - Clone (any type): max 4 per preset
  - Poly effects: max 2 per preset
  - Looper: max 1 per preset
- **DSP optimization tips:**
  - Use both Path 1 and Path 2 (not just split paths of one)
  - Amp, Reverb, Poly effects are most DSP-hungry
  - Cab, EQ, Dynamics, Volume/Pan use less
  - Stereo models use ~2x DSP of mono
  - Use "Simple" variants when available
  - Use controllers/snapshots instead of duplicating blocks

### B.5 Model Browser / Block Library

**Opening the Model List:**
- Tap empty location on path → category buttons appear in Inspector → tap category
- Tap model name in Inspector header (to replace existing block)
- Turn Lower Knob to scroll through models (at empty block: scrolls favorites first)

**Model List Layout:**
- **Left column**: Model categories (Amp, Preamp, Cab, Distortion, Delay, Reverb, Modulation, Dynamics, EQ, Pitch/Synth, Wah/Filter, Volume/Pan, Looper, FX Loop, Split, Favorites)
- **Middle column**: Models for selected category, divided into subcategories
- **Right sidebar**: Subcategories
- **Search field** at top
- **Gallery/List view** toggle button
- **Focus button** in Inspector
- **Based On** information at bottom of list

**Model selection interaction:**

- Press & turn Lower Knob to skip subcategories
- Tap to select and audition (model loads temporarily)
- Double-tap to select and close Model List

**Subcategory icons:**
- **Mono** icon — for mono effect models
- **Stereo** icon — for stereo effect models
- **Legacy** icon — legacy models from Helix/HX family
- Amp subcategories: GUITAR AMP, BASS AMP, LEGACY GUITAR, LEGACY BASS, CLONE
