TTSSEQ.ini in the new Sonar?

I'm using the same Midi Fx that I used in Sonar X3. I got them to behave correctly by editing "MfxLookahead" in the file TTSSEQ.ini. In X3, this was located in %AppData%/Cakewalk. However, the file is nowhere to be found in the new Sonar. Is there no way to edit The Midi FX lookahead? I'm getting really bad overlapping and what seems like missing notes in looped playback when using Midi FX as it is now in the new Sonar.
 
EDIT: TTSSEQ.ini is mentioned in the new documentation....but it's nowhere to be found where it should be.

It's in your user folder: can't recall offhand but something like

C:\Users\<username>\Roaming\Cakewalk\SONAR Platinum

I may have missed out part of the path - apologies if so.

That's the first place I looked, as per my original post. It's not in there.

Have you checked the online help?

I did all of that, guys.
 
Even weirder: After starting up Sonar this morning when I turned on my computer, the file appeared in the Sonar Platinum directory. Very strange.
 
But now, I don't think this solved my issue with missing notes in Addictive Drummer 2. Seems like it only happens when using a midi humanizer plugin on the track, which isn't something that happened in X3 with Slate Drums 4 nor Superior Drummer 2. But I see there's already a thread for that.

Yeah, I tried that. :( I tried the TTSSEQ.ini option of mfxlookahead, and setting Preferences > Midi > Playback and Recording's buffer to > 250. Neither of those worked. These MIDI effects worked just fine in X3 and my other DAW, so I know it's not my machine that's the problem.
 
I've spent since last night on it and I can't figure out why Platinum is giving me this issue. The one MIDI plugin I'm trying to use is called "Frank's MIDI Humanizer" and it's REALLY good at what it's supposed to do with some options that aren't in other humanizers, that's why I'm trying so hard to get this work correctly.
 
This issue is present with any VSTi that uses any humanizer mfx on it's MIDI track, including Cakewalk's (I tried it).
 
Without any MFX, the MIDI playback works as expected.

I'm not sure what changed between X3 and Platinum, but there ya go.

Me either, but any time I hear somebody has a MIDI problem like this - I'll tell them to look at that setting.
I'm the same - I never thought twice about this setting and always had it on the default of 250ms, and never had a problem. Changing it to 500 didn't help me but 999 did. So you're proving that it might even have to go higher ;-)
 
Maybe after all the "new version" traffic dies down, we can find out what's actually changed...

My problem was just playing back a normal drum part (in to Superior 2) that worked fine in X3.
I wasn't doing anything "fancy" at all - but when I loaded the song in to Platinum, it was dropping random notes.
