Activate SynthMachine or Dewhistle
- In the plugin: Copy activation → paste below → download
activation.xml→ Import token in the plugin. - First time on this computer? Enter Gumroad email + license key (
SM-/DW-) or order number / Order ID. - Refreshing or lost the file? Leave email and key blank — we recognise this computer.
Need the plugin download?
After Gumroad checkout, open Find Purchase with your checkout email and order number or Order ID to get your license key and download zip.
New computer or OS reinstall?
Restarting, updating, or renaming this computer does not break activation.
On a new computer or after a clean OS reinstall, enter email + license key (or Gumroad order) and tick the replace option after you submit (up to 2 moves per license; then contact support).
60-day refresh & one computer per license
1 checkout = 1 license = 1 computer. SynthMachine (SM-) and Dewhistle (DW-) use separate licenses.
activation.xml is locked to this computer. Do not share it or your license key.
The file lasts about 60 days. Return here for a free refresh while your license is active — that is normal, not the end of your purchase.
Refunds (SynthMachine paid purchases)
Within 60 days you may request a refund (80% minus non-refundable fees). A refund revokes the license. Full rules: Refund Policy. Dewhistle is free checkout only.
