Triggering MIDI CC Messages via Automation Path: Enhancing Hydrogen's MIDI Capabilities

Introduction

Hydrogen, a popular open-source drum machine, has been a go-to choice for musicians and producers seeking a flexible and feature-rich drum machine. One feature that has been frequently requested by users is the ability to trigger arbitrary MIDI messages. This feature would enable users to integrate Hydrogen with other MIDI devices, software, and hardware, opening up new possibilities for creative expression and control. In this article, we will explore the concept of triggering MIDI CC messages via automation path and discuss the improvements needed to make this feature a reality.

The Need for MIDI CC Messages

MIDI CC (Control Change) messages are a fundamental part of the MIDI protocol, allowing devices to send and receive control data. These messages are used to control various aspects of a device, such as volume, pan, and filter cutoff. In the context of Hydrogen, triggering MIDI CC messages would enable users to control external devices, such as synthesizers, effects processors, and other MIDI controllers. This would greatly expand the capabilities of Hydrogen, allowing users to create complex and dynamic soundscapes.

Automation Paths: The Key to MIDI CC Messages

Automation paths are a crucial aspect of Hydrogen's architecture, allowing users to create complex and dynamic patterns. However, the current implementation of automation paths is limited, making it difficult to assign MIDI CC events to specific paths. To enable the triggering of MIDI CC messages via automation path, significant improvements are needed to the automation path system.

Improving Automation Paths

To make the triggering of MIDI CC messages via automation path a reality, the following improvements are necessary:

Enhanced Automation Path Editing: The current automation path editing system is limited, making it difficult to assign MIDI CC events to specific paths. A more intuitive and user-friendly interface is needed to allow users to easily create and edit automation paths.
MIDI CC Event Assignment: Users should be able to assign MIDI CC events to specific automation paths, allowing them to trigger arbitrary MIDI messages.
Signal Sending: When an automation path changes value, a signal should be sent to trigger the assigned MIDI CC event.
MIDI CC Event Configuration: Users should be able to configure the MIDI CC event, including the channel, note, and value.

Benefits of Triggering MIDI CC Messages via Automation Path

The ability to trigger MIDI CC messages via automation path would bring numerous benefits to Hydrogen users, including:

Increased Creative Control: Users would have greater control over their sound, allowing them to create complex and dynamic patterns.
Improved Integration: Hydrogen would be able to integrate with other MIDI devices, software, and hardware, expanding its capabilities and versatility.
Enhanced Expressiveness: Users would be able to express themselves more creatively, using MIDI CC messages to control external devices and create unique soundscapes.

Conclusion

Triggering MIDI CC messages via automation path is a feature that has been frequently requested by Hydrogen users. To make this feature a reality, significant improvements are needed to the automation path system. By enhancing automation path editing, assigning MIDI CC events, sending signals, and configuring MIDI CC events, users would be able to trigger arbitrary MIDI messages, expanding the capabilities of Hydrogen and enabling new creative possibilities.

Future Development

The development of this feature would require a significant overhaul of the automation path system. This would involve:

Rewriting Automation Path Code: The current automation path code would need to be rewritten to accommodate the new features and functionality.
Adding MIDI CC Event Support: Support for MIDI CC events would need to be added to the automation path system, allowing users to assign and trigger these events.
Implementing Signal Sending: The system would need to be able to send signals to trigger the assigned MIDI CC event when an automation path changes value.
Configuring MIDI CC Events: Users would need to be able to configure the MIDI CC event, including the channel, note, and value.

Roadmap

The development of this feature would follow a phased approach, with the following milestones:

Phase 1: Automation Path Improvements: The automation path system would be improved to make it more intuitive and user-friendly.
Phase 2: MIDI CC Event Assignment: Users would be able to assign MIDI CC events to specific automation paths.
Phase 3: Signal Sending: The system would be able to send signals to trigger the assigned MIDI CC event when an automation path changes value.
Phase 4: MIDI CC Event Configuration: Users would be able to configure the MIDI CC event, including the channel, note, and value.

Conclusion

Triggering MIDI CC messages via automation path is a feature that would greatly enhance the capabilities of Hydrogen. By improving the automation path system, assigning MIDI CC events, sending signals, and configuring MIDI CC events, users would be able to trigger arbitrary MIDI messages, expanding the creative possibilities of Hydrogen. The development of this feature would require significant changes to the automation path system, but the benefits would be well worth the effort.
