From the beginning to the end. From my desktop I use BIAB 2022 now for making my backing tracks Drums Bass and Keys. I convert it to wma and copy it to a sd card that I put into my laptop ( used for live shows) open Power Tracks 2020. Load the wma and save it as an seq file. Everything normal done this for years on older versions of both. Here is where it gets funky. In most of the songs that I have done this way has started doing this strange thing. It will play a minute or two them it sounds like plugging a cable in a guitar while the amp is on for a second or two. It will do this several times in the song if I let it play. It is random. I finally opened the audio window and I can see the spikes in the left channel. The songs will play fine for a few times then suddenly the spikes appear. Doesn't do this with midi files or any mp3 files just the seq files that have been converted. Any ideas?????
