Gramosynth is a collection of pretrained AI models developed by Rightsify, helping research teams speed up data acquisition, expand dataset diversity and lower data licensing costs. Built upon Rightsify's extensive library of over one million hours of human-made music. Gramosynth generates realistic, high-quality synthetic music data that maintains the crucial integrity of ground truth human labeling while delivering high-fidelity 48kHz stereo audio, enabling perpetual data access for research teams.
AI models are increasingly hungry for data, and we're rapidly approaching a "data wall" where human-made content alone won't suffice. At Rightsify, we've licensed millions of our human-made songs to AI companies, giving us unique insights into this growing demand. Synthetic data combined with human-made data represents the future of AI datasets - a perpetual data flywheel that can generate unlimited, high-quality training data.
​
But this isn't just about training AI on AI-generated content - which without extreme levels of dataset curation can lead to model collapse. Gramosynth leverages a pipeline of proprietary pretrained models to continuously incorporate Rightsify’s latest human-made music into its synthetic output through a live stream of daily uploads. This creates a true perpetual data flywheel: as new music is created and immediately fed into the system, Gramosynth learns from it in real-time, generating fresh synthetic data that reflects current trends and evolving styles in music. The result is an ever-expanding, self-refreshing dataset that maintains ground truth by tapping directly into the living, breathing world of human creativity.​​
Gramosynth is powered by Rightsify, the world's largest corpus of commercial music for AI training, ensuring real-time access to high-quality, diverse datasets that are always fresh and immediately available

Is the $50/year per location the complete price?Yes, our $50/year per location pricing is all-inclusive with no hidden fees. This covers unlimited music generation, real-time personalization, and all licensing rights for commercial use. Volume discounts are available for businesses with multiple locations.
-
Can I customize the style of music that plays?You can select moods and playlists that are aligned with your brand and space. However, at this time real-time customization is not available.
-
How does the Background Music service work?BGM uses advanced AI algorithms to generate unique background music tracks for your business environment. All AI models provided by Rightsify are trained on music that we own, meaning that you won't have to pay any license fees to play music in your business.
-
How is music delivered to my business?BGM can be streamed through our easy-to-use web application. The web app works on any device with internet access.
-
How is GCX different from Gramosynth?While Gramosynth offers AI-generated synthetic music datasets, GCX provides human-curated, ethically sourced music data. GCX includes real-world recordings with rich metadata collected and labeled by music professionals, making it ideal for applications requiring authentic human-created content.
-
What kind of metadata is included?GCX includes comprehensive metadata covering musical characteristics (genre, tempo, key, instrumentation, chords), technical aspects (recording quality, format), and contextual information (artist, release date).
-
How is the data delivered?GCX datasets are delivered through secure cloud storage solutions with human support for integration. All data is hosted in secure S3 buckets which can be retrieved from or we can transfer the data to you.
-
How is the ethical sourcing ensured?Every piece of content in Rightsify's GCX library is acquired as a work for hire, with fair compensation provided to creators. We own 100% of the copyrights for each song in our datasets.
-
Who can use Gramosynth?Currently, Gramosynth is available exclusively to research teams developing AI models and academic institutions. We're focused on supporting cutting-edge AI music research and development in these sectors. Gramosynth is not meant for creating music to be made available for consumers (streaming, sync licensing) as a standalone product.
-
How does Gramosynth ensure the quality and relevance of its synthetic music data?Gramosynth maintains high quality and relevance through a comprehensive approach. Our AI models, trained on a diverse and constantly updated library of human-made music, capture nuanced musical characteristics across various genres and styles. We employ rigorous automated checks and reinforcement-learning to ensure accuracy and coherence in the generated data. This process results in synthetic music data that is not only of exceptional quality but also highly relevant for current AI music research and development, closely mirroring the complexity and authenticity of human-created music.
-
What kind of license do I get from using Gramosynth?Rightsify provides a permissive commercial license for using the synthetic output in perpetuity for machine learning models, both commercial and non-commercial. In the United States, AI-generated output has no copyright. For countries outside the US, we issue a traditional master/publishing license to use the works, ensuring global compliance and usability.
-
How can I customize datasets in Gramosynth?Gramosynth offers extensive customization options. Beyond generating full tracks with stems and metadata, you can create stem-only datasets, explore genre-blending, and perform style transfers. For example, you can generate datasets of specific instrument stems, like Acoustic Guitar, or create Piano-only versions of full tracks. This flexibility allows for highly specialized and diverse dataset creation.
-
What types of data are included in the output?All Gramosynth output includes detailed, high-quality annotations, mirroring our human-made datasets. These annotations include, but are not limited to, genre, key, tempo, instrumentation, mood, energy, and more. Audio is exported as FLAC 48kHz, with clean, unprocessed stems. Metadata is available in JSON or CSV format, providing flexibility for various research needs. MIDI generation is also available.
-
How does Gramosynth work?Gramosynth allows you to create custom datasets by specifying your desired output through prompts.

What is synthetic music data?Synthetic music data refers to artificially generated audio and associated metadata that mimics the characteristics of human-composed and performed music. Created using advanced AI algorithms, synthetic music data serves as a valuable resource for training and developing AI models in music-related applications. This data encompasses not just the audio itself, but also detailed annotations such as genre, tempo, key, instrumentation, and mood. Unlike traditional datasets compiled from existing recordings, synthetic data can be generated in vast quantities, with precise control over various musical parameters. It offers several advantages: Scalability: Unlimited generation of diverse musical output Customization: Ability to create data for specific genres, styles, or musical elements Intellectual Property: No concerns about copyright or personal data issues Consistency: Uniform quality and annotation across the dataset
