Purchase and license terms · October 1, 2026

split is desktop software from Practice Brain. Use the five free hand-split generations to check that it works well with your computer and your MIDI files before buying a license.

Five free generations

The trial includes five successful hand-splits per computer, with optional fingerings for those results included. Failed or cancelled generations do not count. Trial generations require an internet connection. You can still edit, play and export existing results after the trial ends.

What you are buying

The price is $25 USD as a one-time payment, plus applicable tax. Checkout shows the final amount, including any currency conversion, before you pay. There is no subscription. Payment is handled through Stripe Managed Payments and sold through Link.

Your purchase provides one product key for unlimited generations on your compatible Mac and Windows computers. Each computer needs an internet connection to activate the key; paid generations then work offline. Your product key is shown after payment and sent to the checkout email address. You can recover it through an emailed verification link. Keep your product key safe. Support is available at support@splitpiano.com.

Compatibility and suggestions

This release supports Apple Silicon Macs (M1 or later) with macOS 14 or later, and Windows 10 or 11 on x64 PCs. Intel Macs and native Windows ARM builds are not included. It accepts MIDI files; audio transcription and music notation are not included.

Hand assignments are predictions and can need correction. Fingerings are an optional experimental feature and may be unreliable. The editor lets you make changes. We do not guarantee that every assignment will be correct; please test your own music before buying. This description does not limit any legal rights if the software is defective or materially misdescribed.

Refunds

We do not offer change-of-mind refunds. The free trial is your opportunity to evaluate split before purchasing.

This does not exclude refunds or other remedies required by applicable law, including any applicable cancellation rights. It also does not override Stripe’s Managed Payments refund policy. Link may provide refunds for eligible problems such as non-delivery, corrupted software, material misdescription, or unauthorized or duplicate payments.

Link generally reviews eligible refund requests made within 60 days of payment under its own policy; this is not an unconditional 60-day money-back guarantee. Read Link’s refund policy for its conditions. Any longer rights provided by law remain intact.

For a purchase problem, contact support with your receipt or order reference and a description of the issue. You can also contact Link through your payment receipt. Do not send payment card details. A full refund ends the purchased license, and you must stop using that product key and its paid activations.

Your license

Practice Brain grants the purchaser a non-exclusive license to use split on their own compatible Mac and Windows computers, including for their own musical work. The paid license does not expire. It is for one person and may not be shared, resold or used to provide activations to others. There is no fixed activation-count limit in this release.

You keep ownership of your MIDI files, projects and exports. Buying split does not transfer ownership of its code, models or sound assets. You may not redistribute extracted models or other proprietary app assets, or bypass licensing controls, except where applicable law expressly permits it. Third-party components remain covered by their respective licenses and credits.

App and model improvements may be delivered through updates. Your license does not depend on installing future updates, and it does not promise future features, indefinite support or compatibility with every future operating system version. Nothing in these terms removes rights or remedies that cannot lawfully be excluded.

These terms apply to purchases made under this version of the policy. Read our privacy information for how trial, activation and purchase data are handled.
