Virus TI 2 chords problem in Studio One

  • Hello!
    I have a problem with playing chords from MIDI event in Studio One. So I've got a lead with two hypersaw oscillators with maximum amount of voices in unison. When I'm playing 7th chords directly from my midi keyboard, I can hear all the notes of the chords, but when I play a midi event where the notes are starting at the same time, Studio One doesn't play all the chord's notes. I've checked it in FL Studio and it works fine there. The latency in Focusrite 2i2 driver is 256 samples. Any thoughts how to solve it in Studio One?
    Thanks in advance.
    Cheers.
