Hi Musikbear,
Firstly I will apologize for anyone reading my over long posts.
I am not going to list all of them (nearly all have this issue, as discussed) trust me, it's lots.
I have given up, at least until a new version, but if you want you can try:
Piano1 if you haven't got it get it, it's excellent, best sounding Piano VST I have heard, small and free, though even more realistic with 64bit version, having superior believable velocity sensitivity.
DSK Choir
Oatmeal
Again they
all play ball with each other at the same wrong pitch along with scores of other ones.
I can well believe it is an issue with 64 bit Windows except I have read that other people have this issue even when changing to the 32bit software (within 64bit windows).
Obviously I am not prepared to downgrade to 32bit Windows for LMMS!!! Especially as LMMS is the only DAW with this strange issue.
I have since tested version 13 today and found the following:
Exactly the same result in terms of pitch issue, albeit with 64bit windows a constant.
However I could move the green box over another key
an incorrect position to achieve correct results (sorry if this sounds confusing, the green box is initially in the right place).
Initially it actually worked correctly with version 13 (press key, get right pitch) then after a few bars it changed to the wrong key again. No matter, moving the green bar to the wrong place solves it!
Sadly this version suffers drop out and random crashes (with VSTs). This is preferable for me, at least with a transparent fault like this I know not to use it, unlike before. 0.15 was very stable but wrong (as described).
LMMS is a great project, long may it continue. I just wish it hadn't messed my playing up thus far. Caveat emptor, except it's free!
