Sometimes we can make changes to channels and midi settings that we forget about. Whats soft thru mean anyway?
In the owner’s manual you will find a list of default settings for the controls. However, we have seen a few isolated cases where large SMF files seem to change settings withintthe PR-300™ on their own, disabling functions of the device. The Reset Procedure has been provided by a user. It does not appear in the owner’s manual. It is part of a test menu. Do not change any of the other T-settings if you do the procedure. Change only T-15. We suggest you refer any questions about the other T settings to a qualified technician.
