I recently purchased 3 downloads of .mid and WAV files from a source in the UK that I've used before without any issues. The files download directly from the vendor's website as a zipped download with MIDI in a separate folder and WAV files for MACOSX or PC in separate folders in the download.
For DAW's I'm using Music Maker 2021 Premium and Acid Pro 10 Suite. After I drag and drop these files into the track composer of either DAW, the .mid files have 20-40 blank bars before any playable music data. The file properties show 02min 34s 500ms (for example), while the actual play time is only 3-8 seconds (3-4 bars). There are a number of solid white files with prefix name of ._ and .DS_Store, which are for MACOSX and I’m not sure if these are causing any problems. I don’t load the MACOSX file into my music folder, just the WAV and .mid files.
I’ve contacted the company where I purchased the files, they are standard (SMF) files and no problems have been reported by other customers similar to mine. I have purchased several product downloads from this company and all previous purchases are working fine in both DAW's. The vendor didn't find any file errors on the 3 recent downloads that I'm having problems with.
My PC (HP desktop) was purchased new last year: Intel Core i7, 64-bit, Quad Processor, 32GB RAM, 1.5TB Storage, 2.90GHz. I've completely reloaded Windows 10 with updates/drivers and ran every diagnostic, update and repair tool available with HP Support. I've been trying to get this issue fixed for several weeks and have tried everything I know. I've considered loading a Midi File repair program, but I don't know and unsure which one is best to fix my specific issue, or which are safe.
I can send screenshots of what I'm seeing or a few actual files. If anyone can help, I'd greatly appreciate it.
