Make macros more flexible and dynamically instantiated

[mickmister]

At the moment, there’s not really an abstraction available to allow the user to make their own dashboard or combination of macros to make their own workflow. Every call to ‘create macro’ is more or less at “compile time”. Not literally, more like initialization time. This initialization runs on the server and clients since it’s running isomorphically in the springboard feature modules. Each feature module are currently POCs of feature implementations, but there are shortcomings due to the hardcoded nature. The features currently don’t scale for user customization.

The task here is to design a more data-driven way for macros to be handled. When the config for macros change, all macros in the app should rehydrate based on the data changes. I think they are generally stateless besides editing form state, so I think the hydration is feasible.

We should support the user arbitrarily wanting to assign midi controls to inputs and outputs. For example, the user may want to assign a given midi input, lock in the midi number range to 50-100 (meaning 0=50 and 127=100), and then select a midi output for the control change output as well. So this workflow block would be a tuple of midi_control_change_input and midi_control_change_output macros. The user should arbitrarily be able to add more of these and configure them.

Check out the packages at ‘packages/jamtools/core’ and ‘packages/jamtools/features’ for source and examples. Specifically, check out the inputs accepted by each individual macro type in https://github.com/jamtools/jamtools/tree/main/packages/jamtools/core/modules/macro_module/macro_handlers

@claude You are an expert on typescript best practices and scalable frameworks. Please make a comprehensive plan of exactly how this can be implemented.

Comprehensive Implementation Plan for Dynamic Macro System

Todo List

• Read repository guidelines (CLAUDE.md)
• Analyze current macro system architecture
• Examine existing macro handlers
• Understand current limitations and hardcoded nature
• Design data-driven macro configuration system
• Plan dynamic macro instantiation mechanism
• Design user customization interface
• Create comprehensive TypeScript implementation plan
• Document scalable framework approach

Current System Analysis

Current Architecture

The macro system consists of:

• Macro Handlers: Located at packages/jamtools/core/modules/macro_module/macro_handlers/
• Input Handlers: midi_control_change_input, midi_button_input, musical_keyboard_input, etc.
• Output Handlers: midi_control_change_output, midi_button_output, musical_keyboard_output
• Registration System: Uses macroTypeRegistry.registerMacroType() at initialization time
• Configuration: Static configurations created via createMacro() calls in feature modules

Current Limitations

1. Compile-time Registration: All macro types are registered during module initialization
2. Static Configuration: Macros are created with fixed configurations in code
3. No Runtime Reconfiguration: No ability to modify macro configurations after creation
4. Hardcoded Workflows: Complex workflows like MIDI CC input→output chains are manually coded
5. Limited User Customization: No UI for users to create/modify macro configurations
6. Module Coupling: Feature modules directly call createMacro() with hardcoded parameters

---

Comprehensive Implementation Plan

1. Data-Driven Configuration Schema

// New configuration types
export interface MacroWorkflowConfig {
  id: string;
  name: string;
  description?: string;
  enabled: boolean;
  macros: MacroNodeConfig[];
  connections: MacroConnectionConfig[];
}

export interface MacroNodeConfig {
  id: string;
  type: keyof MacroTypeConfigs;
  position: { x: number; y: number };
  config: any; // Type-safe based on macro type
  customName?: string;
}

export interface MacroConnectionConfig {
  id: string;
  sourceNodeId: string;
  targetNodeId: string;
  sourceOutput?: string;
  targetInput?: string;
}

// Enhanced macro type registration
export interface MacroTypeDefinition {
  id: keyof MacroTypeConfigs;
  displayName: string;
  description: string;
  category: 'input' | 'output' | 'processor' | 'utility';
  icon?: string;
  configSchema: JSONSchema; // For UI generation
  inputs?: MacroPortDefinition[];
  outputs?: MacroPortDefinition[];
}

export interface MacroPortDefinition {
  id: string;
  name: string;
  type: 'midi' | 'control' | 'data';
  required: boolean;
}

2. Dynamic Macro Instance Management

export class DynamicMacroManager {
  private activeWorkflows = new Map<string, MacroWorkflowInstance>();
  private macroTypeDefinitions = new Map<string, MacroTypeDefinition>();
  
  // Workflow lifecycle
  async createWorkflow(config: MacroWorkflowConfig): Promise<string>;
  async updateWorkflow(id: string, config: MacroWorkflowConfig): Promise<void>;
  async deleteWorkflow(id: string): Promise<void>;
  async enableWorkflow(id: string): Promise<void>;
  async disableWorkflow(id: string): Promise<void>;
  
  // Runtime reconfiguration
  async rehydrateWorkflows(): Promise<void>;
  async rehydrateWorkflow(id: string): Promise<void>;
  
  // Configuration persistence
  async saveWorkflowsToStorage(): Promise<void>;
  async loadWorkflowsFromStorage(): Promise<MacroWorkflowConfig[]>;
}

export class MacroWorkflowInstance {
  private macroInstances = new Map<string, any>();
  private connectionHandlers: Array<() => void> = [];
  
  constructor(
    private config: MacroWorkflowConfig,
    private macroAPI: MacroAPI,
    private macroManager: DynamicMacroManager
  ) {}
  
  async initialize(): Promise<void>;
  async destroy(): Promise<void>;
  async reconfigure(config: MacroWorkflowConfig): Promise<void>;
}

3. Enhanced Macro Type System

// Extend existing macro handlers to support connections
export interface ConnectableMacroHandler {
  inputs: Map<string, Subject<any>>;
  outputs: Map<string, Observable<any>>;
  connect(outputPort: string, target: ConnectableMacroHandler, inputPort: string): void;
  disconnect(outputPort: string, target: ConnectableMacroHandler, inputPort: string): void;
}

// Enhanced registration with metadata
export const enhancedMacroTypeRegistry = {
  registerMacroType<T extends keyof MacroTypeConfigs>(
    definition: MacroTypeDefinition,
    handler: MacroCallback<MacroTypeConfigs[T]['input'], MacroTypeConfigs[T]['output']>
  ): void;
  
  getMacroTypeDefinition(typeId: string): MacroTypeDefinition | undefined;
  getAllMacroTypes(): MacroTypeDefinition[];
  getMacroTypesByCategory(category: string): MacroTypeDefinition[];
}

4. User Interface Components

// Workflow builder components
export const WorkflowBuilder: React.FC<{
  workflow: MacroWorkflowConfig;
  onChange: (workflow: MacroWorkflowConfig) => void;
}>;

export const MacroNodeEditor: React.FC<{
  node: MacroNodeConfig;
  definition: MacroTypeDefinition;
  onChange: (node: MacroNodeConfig) => void;
}>;

export const MacroLibrary: React.FC<{
  onAddNode: (typeId: string, position: { x: number; y: number }) => void;
}>;

// Configuration forms (auto-generated from schema)
export const MacroConfigForm: React.FC<{
  schema: JSONSchema;
  value: any;
  onChange: (value: any) => void;
}>;

5. MIDI Control Chain Example Implementation

// Template for MIDI CC input → output chain
export const createMidiCCChainTemplate = (
  inputDevice: string,
  inputChannel: number,
  ccNumber: number,
  outputDevice: string,
  outputChannel: number,
  outputCCNumber: number,
  valueRange: [number, number] = [0, 127]
): MacroWorkflowConfig => ({
  id: generateId(),
  name: `MIDI CC Chain ${ccNumber}→${outputCCNumber}`,
  description: `Maps CC${ccNumber} from ${inputDevice} to CC${outputCCNumber} on ${outputDevice}`,
  enabled: true,
  macros: [
    {
      id: 'input',
      type: 'midi_control_change_input',
      position: { x: 100, y: 100 },
      config: {
        deviceFilter: inputDevice,
        channelFilter: inputChannel,
        ccNumberFilter: ccNumber
      }
    },
    {
      id: 'processor',
      type: 'value_mapper', // New processor type
      position: { x: 300, y: 100 },
      config: {
        inputRange: [0, 127],
        outputRange: valueRange
      }
    },
    {
      id: 'output',
      type: 'midi_control_change_output',
      position: { x: 500, y: 100 },
      config: {
        device: outputDevice,
        channel: outputChannel,
        ccNumber: outputCCNumber
      }
    }
  ],
  connections: [
    {
      id: 'input-to-processor',
      sourceNodeId: 'input',
      targetNodeId: 'processor',
      sourceOutput: 'value',
      targetInput: 'input'
    },
    {
      id: 'processor-to-output',
      sourceNodeId: 'processor',
      targetNodeId: 'output',
      sourceOutput: 'output',
      targetInput: 'value'
    }
  ]
});

6. Migration Strategy & Implementation Steps

Phase 1: Core Infrastructure

1. Create configuration types and schemas
2. Implement DynamicMacroManager class
3. Extend macro registration system with metadata
4. Add persistence layer for workflow configurations

Phase 2: Enhanced Macro Handlers

1. Refactor existing handlers to support connections
2. Add new processor types (value mapper, filter, etc.)
3. Implement connection management in macro instances
4. Add runtime reconfiguration support

Phase 3: User Interface

1. Build workflow builder UI component
2. Create macro library browser
3. Implement drag-and-drop workflow editor
4. Add configuration forms with schema validation

Phase 4: Templates & Presets

1. Create workflow templates for common use cases
2. Implement preset management system
3. Add import/export functionality
4. Build template marketplace (future)

Phase 5: Migration & Testing

1. Create migration tools for existing workflows
2. Implement backward compatibility layer
3. Add comprehensive testing for dynamic workflows
4. Performance optimization for large workflow graphs

7. TypeScript Best Practices Applied

• Strict type safety with discriminated unions for macro configurations
• Generic constraints for type-safe macro creation and connection
• Builder patterns for complex configuration objects
• Observable patterns for reactive data flow
• Dependency injection for testable macro instances
• JSON Schema validation for runtime type checking
• Immutable data structures for predictable state management

8. Scalability Considerations

• Lazy loading of macro handlers
• Connection pooling for MIDI operations
• Efficient re-rendering with React.memo and selective updates
• Background processing for heavy computational macros
• Memory management for long-running workflows
• Error boundaries and graceful degradation

This architecture provides a solid foundation for making macros truly dynamic while maintaining TypeScript safety and performance scalability.

Gap Analysis for Dynamic Macro System Implementation Plan

Todo List

• Read repository guidelines (CLAUDE.md) - No CLAUDE.md found
• Examine current macro system architecture in detail
• Analyze previous implementation plan comprehensively
• Identify gaps in developer experience considerations
• Identify gaps in technical implementation details
• Identify gaps in migration and compatibility
• Identify gaps in testing and validation
• Provide specific recommendations for addressing gaps

---

Critical Gaps Identified in Implementation Plan

1. Developer Experience & Framework Usability Gaps

Missing: Simplified Developer API

The current plan lacks a streamlined developer-facing API. Developers currently use:

// Current simple API
const macro = await macroModule.createMacro(moduleAPI, 'name', 'type', config);

Gap: No clear migration path for this simple API in the new data-driven system. The plan focuses heavily on UI-driven configuration but developers still need programmatic macro creation.

Recommendation: Provide both APIs:

// New programmatic API alongside data-driven
const workflow = await macroManager.createWorkflowFromTemplate('midi-cc-chain', {
  inputDevice: 'My Controller',
  outputDevice: 'DAW',
  // ...
});

Missing: Type Safety for Dynamic Configurations

The plan uses any types for dynamic configurations, breaking TypeScript's main value proposition.

Recommendation:

// Type-safe dynamic configuration
export interface TypeSafeWorkflowConfig<T extends WorkflowTemplateType> {
  id: string;
  template: T;
  config: WorkflowTemplateConfigs[T];
}

2. Technical Implementation Gaps

Missing: Reactive Connection Management

The plan mentions connections but doesn't specify how data flows between nodes in real-time.

Gap: No specification for:

• Backpressure handling in connection chains
• Error propagation through workflows
• Performance optimization for high-frequency MIDI data

Recommendation:

export interface ConnectionManager {
  createConnection<T>(source: Observable<T>, target: Observer<T>): ConnectionHandle;
  withBackpressure(strategy: 'drop' | 'buffer' | 'throttle'): ConnectionBuilder;
  withErrorRecovery(handler: ErrorHandler): ConnectionBuilder;
}

Missing: Hot Reloading/Live Reconfiguration Details

The plan mentions "rehydration" but lacks specifics on how to avoid interrupting live MIDI streams during reconfiguration.

Gap: How to handle:

• Graceful shutdown of active connections
• State transfer between old/new workflow instances
• Maintaining MIDI timing during transitions

3. Migration & Compatibility Gaps

Missing: Backward Compatibility Strategy

Current feature modules like midi_thru_cc_snack.ts directly call createMacro().

Gap: No clear migration strategy for existing codebases.

Recommendation: Compatibility layer:

// Compatibility wrapper
class LegacyMacroAdapter {
  createMacro<T extends keyof MacroTypeConfigs>(
    moduleAPI: ModuleAPI, 
    name: string, 
    type: T, 
    config: MacroTypeConfigs[T]['input']
  ): Promise<MacroTypeConfigs[T]['output']> {
    // Convert to workflow internally but maintain same API
    return this.dynamicMacroManager.createLegacyMacro(name, type, config);
  }
}

Missing: Data Migration Strategy

Existing persistent state keys like getKeyForMacro('saved_midi_event', fieldName) need migration.

Gap: No plan for migrating existing user configurations to new workflow format.

4. Framework-Specific Gaps

Missing: Springboard Integration Details

The plan doesn't address how workflows integrate with Springboard's module system.

Gap:

• How workflows register routes
• Module dependency management for dynamic workflows
• Integration with Springboard's state management

Missing: Platform Considerations

JamTools supports multiple platforms (web, mobile, desktop, server).

Gap: No consideration for:

• Platform-specific macro limitations
• Offline workflow execution
• Mobile UI constraints for workflow builder

5. Testing & Validation Gaps

Missing: Workflow Validation Framework

Gap: No specification for:

• Validating workflow configurations before deployment
• Testing macro connections and data flow
• Performance testing for complex workflows

Recommendation:

export interface WorkflowValidator {
  validateConfiguration(workflow: MacroWorkflowConfig): ValidationResult;
  validateConnections(workflow: MacroWorkflowConfig): ConnectionValidationResult;
  testDataFlow(workflow: MacroWorkflowConfig): Promise<FlowTestResult>;
}

6. Performance & Scalability Gaps

Missing: Resource Management Strategy

Gap: No clear plan for:

• Memory management for large workflow graphs
• CPU usage optimization for real-time MIDI processing
• Connection pooling and cleanup strategies

Missing: Real-time Constraints

MIDI requires low-latency processing (<10ms).

Gap: No specification for maintaining real-time performance with dynamic workflows.

---

Priority Recommendations

1. Create Legacy Compatibility Layer First - Essential for adoption
2. Design Type-Safe Configuration System - Maintain TypeScript benefits
3. Specify Real-time Connection Management - Critical for MIDI performance
4. Build Validation Framework - Prevent runtime failures
5. Address Platform Integration - Ensure Springboard compatibility

The implementation plan is architecturally sound but needs these gaps addressed for successful developer adoption in a framework context.

const output = await macroModule.createMacro(moduleAPI, 'Output', 'midi_cc_output', {});
input.subject.subscribe(evt => output.send(evt.event.value));

After (Dynamic System):

// 1. Legacy code still works exactly the same (zero changes required)

// 2. New template-based approach for the requested use case
const workflowId = await macroModule.createWorkflowFromTemplate('midi_cc_chain', {
    inputDevice: 'My Controller',
    inputChannel: 1,
    inputCC: 1,           // User can configure any CC number
    outputDevice: 'My Synth', 
    outputChannel: 1,
    outputCC: 7,          // Maps to any output CC
    minValue: 50,         // Custom value ranges: 0-127 → 50-100
    maxValue: 100
});

// 3. Hot reload configuration changes
await macroModule.updateWorkflow(workflowId, updatedConfig);
// Workflow continues running with new settings - no MIDI interruption!
