ASIO vs WMA vs Windows mixer volume is not the question. The question is that Style Preview HAS its own volume control that does not work. Well, it seems to work but it reverts to a fixed value (2 in my case, don't ask me why). This worked before. It's a BROKEN feature. Like many others.
After struggling with many new bugs in the last 5 years (V2020 to V2024, from Megapack to Audiophile) I think it is more productive to stick with known bugs and live without new features. Less stress. Less money. More time to make music with limited tools. I'll vote this with my wallet in 2025.
I have a lot of sympathy for you. I have used BB for at least twenty years, the programming has always been very poorly implemented. Having has more crashes and issues in BB than any other program I own (and I have many hundreds), I now only use BB as playback for rehearsing a few chords.
BIAB updates are very expensive. Cubase updates - by comparison are about $100. There are some things that it does well principally real tracks but a lot of it has a distinct Windows 95 (and has not changed since) feel and it lags behind in development. It took ages to even produce a Win64 version - years of waiting even once every other program changed. I was looking forward to using my VSTs but nope they all crashed. I just lost all faith in stable programming and that is why I rarely post anymore. This new install just wiped all my songs from my songs folder.
As for volume control. You say there "is" a volume control? Well, I can't find it. ALL my auditions were playing back at a minuscule volume. Today, PG has informed me that each individual track has a volume control. This is no help when you have over 10,000 styles. I think you may mean the plus sign sub-menu represented with only a + sign. This only affects one track at a time and when you have 10,000 this is no help.
As things stand, someone using Asio has to guess that the demos do not use Asio and use Windows Audio. Further, if you turn down the Windows control when NOT using BIAB, when you come back to BIAB you have the same low volume issues repeated. I realized this but others may not. In older versions of BIAB, there was a global volume control for all the tracks. This was visible at the bottom of the style picker. It had a repeat function too. This needs a return.
BB does have many strengths. Principally real tracks, it's main GUI is easy to use but it needs updating and could do much more. Other clickable GUIs are a hotch potch of this and that. BB has an enormous number of real tracks and I know of no program that can compare but it's still poorly programmed. The way I see BB is that it is a Rolls Royce of a program floating on a dodgy wooden raft.
