Usage limitationsPlease note that “Pro” and “Pro Unlimited” accounts are both subject to monthly upload limits and a maximum individual file size. This is necessary to ensure the stability of the Platform. Individual uploads must not exceed 500MB and the upload time per month must not exceed 20 hours in total.
This will not affect the ability of “Pro Unlimited” users to upload an unlimited number of sounds, provided that individual files are within the file limits, and provided that the monthly upload limits are not exceeded.
