Midi rendering bug (or not?)

Hi!
I have an edit with wave tracks and three midi tracks. I use Sonatina Orchestra plugin on two of them. Playback in Waveform is normal, but in rendered output file midi notes renders lower than real. Project was created in Traction and had the same problem in T7, then after upgrade to Waveform it works fine for a couple of days and two new edits. No problems in other projects with this plugin, no problems in some of the edits of this project, but it seems that problem appears after midi track editing. So now I need to render midi separately first. Is this a bug or I just change something and didn't notice?

Do you mean that the audio output from the Sonatina Orchestra synth is lower than expected or that you're doing a MIDI export and the resulting MIDI file is transposed down?
Do any other synths render transposed or is it just limited to Sonatina Orchestra? Do they perhaps have an internal transpose setting that is accidently on?

I mean final render only and sonatina only. If I export a file to flac, than sound from sinatina is lower. If I render just sonatina track right in waveform, than it's fine. No problems with other plugins and in other projects with sonatina. No transpose in midi, but I use realtime pitch shift on other tracks (wave, not midi).

Are you sure this isn't just that the master volume is set to -3dB by default?
If you render a track, it won't go through the master volume, if you export the whole Edit it will and then the master volume will be applied to the track.

(Yes, it is. -14db, to be correct. But on render I checked normalization.)
Sorry for misunderstanding. I've meant "lower pitch", not volume of track. The problem is: midi track with this plugin in specific edit of the specific project suddenly start to render with lower tone on export. But when I render just this track separately with "render track" button on bottom panel, it sounds normal.
Can it be a resampling issue? I use 48000khz in asio setting, but downsample it to 44100 on export. But if it is, then why separate rendered midi track is ok, unlike final mix?

After latest update 8.1.2 it seems to work correct now.
