These are patches you can download into various Audio Softwares to use in your setup - live or studio.
Depending upon the version you are planning on using, you may need additional files or software to get it working. This is just because you're getting literally what I'm making for my own work :)
Kontakt Versions: Kontakt 5 only, no additional requirements
Ableton Sampler Versions: Ableton Sampler required, no additional requirements.
MainStage Versions: Nothing additional required
Reason: You'll need the same Refills I used - Atmosphere Pads has a patch that needs SR Retro Keys, Dream Pianos needs Reason Pianos and Abbey Road. The other patch bundles are stock-sample friendly.
