Get back to
making music.
Where are my downloads and receipts?
Purchases and free downloads are managed by Gumroad. Use the download link on your Gumroad receipt or sign in using the email used for purchase. For payment, refunds or a missing download, start with your Gumroad purchase record.
How do I install the plugins?
Download the package supplied through the relevant Gumroad product, back up important DAW sessions and follow the included installer and manual. After installing, restart or rescan the plugins in your DAW. Make sure the plugin edition matches what you purchased.
How do I evaluate a mix change?
Compare the Original and Processed states at a similar listening level. When reporting an A/B issue, note the DAW, plugin edition/version and exact steps. Do not assume a level change alone is a tonal improvement.
Where can I try the tools first?
MixBrain V3 FREE allows up to 8 Nodes and uses the core QuickMix/Transform processing. GainBrain Free and IronPath Free are distributed together as a separate free pair. Their download pages are linked below.
