All discs are subject to the following licensing arrangement.
You MAY use any and all sounds on our Optigan/Orchestron discs to create derivative works for commercial or private use without any further licensing fee beyond the original purchase price of the discs. No credit to optigan.com is required. If your Optigan/Orchestron resides in a commercial studio which you operate, this license also extends to your clients.
You MAY NOT simply copy the sound contents of the discs and distribute the material directly as sample loops, either commercially or privately.
You MAY NOT make physical copies of the actual discs themselves, other than for private use/experimentation.
