Virus TI Latency WITHOUT TI

Hi !
Recently I decided to use my Virus TI without TI, cause TI is not working for me, and because, I should have 100% safety without TI (I mean, not having crash/latency, etc.)

So, I bought a soundcard (Roland Quad Capture) and a software (VirusHC in order to edit my Virus TI2 faster).

Problem : when recording, I have a delay of the playback for ANY track of the virus. But I think it is a problem related to FL Studio 12 wich I use, and not the TI.

But the real problem is it : even without TI (no usb, just midi cables) I still have latency when playing my Virus.

I just recorded it, to give you an example : http://picosong.com/vxPN/

There is short delay between the notes, how is it possible, since I don't use usb ?

Also, I am not sure, but it looks like the problem appear while using hypersaw.

For example, before recording the arp, I tried with a simple sine wave, and it was playing in time, but with hypersaw it sound not synchronized.

Thanks for your help !!

EDIT : It is happening not only with Hypersaw, but also with classic waveforms, etc.

Also, there still the same sync problem when using no editor (Virus ==> interface ==> PC).

Here is how simple chord sounds with only Virus linked with midi :http://picosong.com/vx6L/

So we can hear that there is clearly a sync issue...

Hi, thanks for your help.

All the sounds are played with midi (piano roll), I never use the arp.

You should hear that the chord is not playing 100% in time, I mean it sounds a little bit like a swing effect.

I have no other hardware synth, no other interface (I have a lexion alpha, but it does not have midi connection) and no other DAW...

I am desperate... I don't know how I could fix it, and I don't know even if it is possible to fix... Since the problem may come from my Virus...
