So, maybe start eliminating all possible influences one by one: What's exactly your computer, type, processor, internal memory, windows, power supply strong enough, how many USB devices use just one USB controller at the same time? (f,i, make a screendump Belarc advisor, or post a saved HTML file). And what software is running at the same time, see taskmanager?. Alas one cant make a screendump from a MOBO BIOS, but a phone might do the job. PS ever updated it's BIOS? Maybe the power supply sucks, happens often when it gets older; voltages can by vary-ing, ... ever cleaned out dust? Monitored hardware temperatures, there are tools for that showing sensor output? Sometimes a cooler sucks and things get locally too hot, like processor, memory .... F

Ok glad to hear that it seems to be fixed. I still want to respond to clarify my points.

Quote:

I didn't have any plugins enabled. Just the MS Wavetable for MIDI cuz this was just sort of a test song file I had BiaB generate.


So you can confirm that if you run Band-in-a-Box from your new folder the CPU spikes don't happen, but if you run Band-in-a-Box from the OLD folder the spikes DO happen. (that would definitely be useful information by itself). With your new bbw you are using the GS Wavetable and not using a DXi synth, if I understand what you said (?) If that's the case it certainly DOES seem like a plugin you were using is responsible for this, or at least aggravating the problem.

It was spiking all over the place when it was distorting really badly


What was spiking... overall CPU usage? Next time that happens, look to see what individual process is spiking and you might have your answer.

I don't have Bluetooth or wifi on this machine. I can disconnect the Network adapter easily enough, but I'll bet that isn't the problem. Because, once again, I didn't used to have this problem prior to 2019. So I dunno why the network adapter should suddenly cause problems.


A couple things: (1) If you installed 2017 (into a different folder) and compared with 2019 with default settings I would be surprised if you noticed that significant a difference in CPU usage. i.e. I think it is more likely that something on your system changed or some setting in the program. But you could confirm that easily enough by installing 2017 and trying it.

(2) There are definitely reasons why network related activity could contribute to problems with audio playback. I don't see why you wouldn't just eliminate the possibility... you've probably already spent countless hours doing complicated things, all I suggested is one simple test.

But you're right, if it isn't broken...

Welp, being a big believer in Occam's Razor, I decided to try the simplest thing first. One suggestion that was made was that I reset BiaB back to factory settings. I was loathe to do this because of various tweaks I've made, but considering that I've installed another copy now, I figured, hey, what could it hurt. So I booted v2019 from the offending directory and reset it to factory settings. Then I loaded this same Melodist-generated file with the five RealTracks that has been giving me so much grief and gave it a spin. And guess what. No distortion. A minimum of rice krispies that cleared up after about 20 measures, which might actually have been caused by my moving the mouse around.

So, now we know that I had something set with the fist 2019 install that it really didn't like. I note that BiaB was nice enough to save my settings so that will give me the opportunity to reinstall them and then go through things one by one to find out what the culprit was.

I'm just really glad that we've finally solved this riddle -- a riddle that stumped PGM's senior tech, by the way.

So onward and upward. I have bars and bars to go before I sleep.
