Rather than a new thread, thought I was just tack on to my current LOR conversion situation. Since the above thread was posted, the latest releases have a new checkbox 'Map empty LMS channels.' So I check that but instead of converting 112 LOR channels, xLights converts 115. The difference is 3 dummy rows used for beats - there is no LOR channel assigned to them. If I remove them and convert again, 112 channels converted and everything is mapped correctly. If I uncheck the 'Map empty LMS channels', then 32 channels with no effects (singing faces) are not mapped but all the other channels are off by this difference. Any others have this situation? For now, I can just create a temp file with the 'beat rows' removed and it should convert fine.
