What is Hydra?
Gramosynth helps AI labs build training data, the examples used to teach an AI model, for music and multimodal projects. Rightsify describes it as a way to generate synthetic music data from a licensed music corpus. Instead of relying only on existing recordings, teams can shape datasets around genres, instruments, and moods.
A dataset can combine generated music with ground-truth human labels, giving model teams labeled examples alongside synthetic audio. Gramosynth describes this as a way to expand data while keeping a connection to human-created music.
Gramosynth is aimed at AI research teams and developers building music models, not people looking for a consumer music generator. The public site offers few technical details about dataset formats, limits, or integrations, so teams should request a demo before deciding whether it fits their pipeline.
Who is Using Hydra?

Which Hydra plan should you pick?
Start with the Annual License for web-based AI music generation and commercial rights; contact Rightsify for volume discounts or use the separately announced API plans when integrating programmatically.
Annual License
Good for artists, creators, and businesses who need unlimited AI-generated music, commercial licensing rights, web access, support, and model updates.
Hydra Use Cases
Expand music-model training data
When existing music examples are not enough, synthetic data can add more material for model training.
Outcome: A larger pool of music examples for AI research.
Build attribute-specific datasets
Genre, instrument, and mood choices help focus a dataset on a particular research question.
Outcome: A packaged dataset shaped around selected musical attributes.
Pair synthetic audio with labels
Human ground-truth labeling gives generated examples additional reference for model work.
Outcome: A dataset that combines synthetic music with human labels.
Workflow Ideas with Hydra
Create a focused training dataset
- 1Define the music-model task and the gaps in your current data.
- 2Choose relevant genres, instruments, and moods.
- 3Ask Rightsify for a demo and confirm dataset contents and delivery details.
Evaluate synthetic data in model research
- 1Identify a model experiment that needs additional music examples.
- 2Discuss a dataset with the musical attributes relevant to that experiment.
- 3Review the dataset and its human labels with your research team.
How Hydra fits into your stack
AI model research
Gramosynth is positioned as a source of synthetic music data for AI research. Teams can evaluate it alongside their existing training examples.
Dataset planning
Genre, instrument, and mood choices help define the musical content of a dataset. Confirm available controls and outputs with Rightsify.
Data procurement
The public site directs interested teams to request a demo or contact Rightsify, rather than documenting a self-serve setup.
Pros
- +Music-focused data: Designed for teams training music AI models.
- +Dataset shaping: Genre, instrument, and mood choices help target a research need.
- +Human labels: Packaged datasets can include ground-truth human labeling.
Cons
- −Limited public detail: Buyers may need a demo to understand the exact deliverables.
- −Research-focused: It is not presented as a tool for making finished songs for everyday listening.
Limitations & when to consider alternatives
Known limitations
- Technical details are sparse. The public Gramosynth pages do not spell out dataset formats, technical limits, or integration options.
- Pricing depends on project needs. The official dataset pricing page says costs depend on use case and data volume, and directs buyers to discuss exact costs.
Look elsewhere when
- You need a documented self-serve product with clear dataset formats and usage limits.
- Your team needs a published API or named integrations before evaluating a vendor.
How to Use Hydra
- 1
Define the data need
Describe the music or multimodal model you are developing and what is missing from its training data.
- 2
Choose dataset attributes
Set the genres, instruments, and moods that should shape the generated examples.
- 3
Request a demo
Contact Rightsify to see how Gramosynth could address your dataset requirements.
- 4
Confirm the deliverables
Ask about labels, data format, volume, licensing, and how the dataset will reach your team.
