Terms & refunds

Last updated: 24 October 2026

By buying from Pro Style Music (prostylemusic.net) you agree to these terms.

Products and licence

  • We sell digital Voice & Style expansion packs and Style-only packs for Yamaha arranger keyboards.
  • Each purchase is licensed to one keyboard. Voice & Style packs are built for the keyboard identified by the Instrument Info file you upload.
  • You may not resell, share or distribute our packs or files.

Ordering and payment

  • Prices are in USD. There are no delivery charges.
  • Payment is made through PayPal only — with a PayPal account, or a credit or debit card through PayPal.
  • For Voice & Style packs, you upload your keyboard's Instrument Info file (.n27) when you buy. We read your keyboard model and Hardware ID from it.
  • Before buying, you confirm that this file was exported from your own keyboard. We build the pack for the keyboard in that file. If you upload the wrong file, we are not responsible for rebuilding the pack for another keyboard.
  • Each order is for one keyboard only. To use a pack on another keyboard, you need to buy it again.

Delivery

  • After payment you receive an email with a private link to your order page, where you can find your downloads and invoice.
  • Style-only packs and song styles can be downloaded immediately after payment from your order page.
  • Voice & Style packs are built for your keyboard and the download link is emailed to you within 24 hours.
  • Download links are temporary. You can create a new link from your order page or from My account.

Upgrades

Some packs have an upgrade price. It is applied automatically when your Instrument Info file shows that your keyboard already owns the required packs.

Refunds

Our packs are digital goods and are non-refundable. We will refund you if:

  • you paid more than once for the same pack for the same keyboard, or
  • we cannot deliver your pack.

If you have a problem with your order, please email us before anything else — we will do our best to help.
