I'm a FL studio user (since 2003, now on version 20.7.1) and purchased the Korg Collection 2 last week to work in FL Studio. Watching the positive review videos on Youtube and reading elsewhere convinced me to indulge.
Overall I'm quite impressed with the VST collection!
In FL Studio, all the other Korg VSTs in the collection appear to be working absolutely fine (wow!) but I've encountered worrying issues with the Triton which I'm sharing in the hope that there may be a work-around someone has found, or Korg could please look into and patch / update???
As a stand-alone install, the Korg Triton is fine. But when used in my FL Studio DAW with ANY Arp instrument, the timing is way out/off-beat with other instruments in playback ( including out of sync with the family of Korg VSTs, they seem to work absolutely ok ).
Making a simple piano-roll pattern featuring the Korg Triton VST and adding to the playlist is really disappointing, consequently exporting a track to audio is a complete waste if the Korg Triton VST is used.
To describe a little further (apologies for non-expert explanation) on making patterns with piano roll / midi-out to the the Korg Triton VST using ANY Arp instrument, the initial note triggered is off-beat, thus the first note does not sound correctly triggered. So when you hear the playback, the "first note" that should be triggered, isn't, and consequently the playback sounds completely off-beat with the rest of the pattern instruments (channels in FL Studio).
Using the FL Studio buffer length and offset adjustment doesn't appear to make any difference whatsoever.
So as long as the Triton VST is not used in FL Studio, working with the other Korg VSTs with FL Studio *piano roll is absolutely fine!

*Regardless whether the Triton VST is in COMBI or PROG mode, the latch engaged or not, the timing is out of tempo with the pattern / other instruments.
There have also been a few screen glitches within the Korg Triton VST user interface that disappear when it is "closed", but occasionally reappear - even if it is the only VST instance in operation.
Apart from that, the tempo adjust in FL Studio seems to work with the Korg Triton VST, and so long as I don't use it in any patterns, the rest of the Korg collection VST's sound lovely! LOL!
I do not believe there is an issue with Fl Studio but I'll keep an open mind.
Like I said, there are no issues with the family of KORG VSTs in the collection, only the Korg Triton VST.
Like I said, as a stand-alone VST (not in the FL Studio DAW) the Korg Triton VST sounds great, midi ok, etc.
I can see there's a hell of a lot of work put into all these KORG VSTs but alas, I can not use the Triton Triton VST in FL Studio, and this is the one VST I really, really, really wanted to work as good as the others!

I apologise if this, my first post, is posted under the wrong section.
