Hey guys,
A few days ago I opened a thread (https://users.cognitone.com/content/synfire-seems-out-sync) about the latency of internal GM synth.
I thought it was a GM synth problem but yesterday after I purchased Synfire express I reinstalled everything and now I got a huge latency with vst, GM synth and everything.
The latency is so big that I can visually see it..at least 1/4 of latency/delay.
In the audio settings I choose ASIO driver and my RME souncard.
is there any setting that I can look at?
thank you

There should be no latency during playback, if all sounds are hosted by the same host (Synfire or DAW).
You will see a latency, if sounds are on different hosts, e.g. Synfire engine and Microsoft GM Synth, or Synfire engine and a DAW. Then individual sounds may be shifted against each other.

By saying "visible", do you mean the placement of notes you recorded with Synfire?
If so, please check "Use Audio Engine for MIDI Input" on the Settings tab of AUdio & MIDI Setup.
Also make sure your metronome sound is hosted also on the Engine (not GM Synth).

Ok, then the delay is in the sound itself, or in the plug-in. Cymbals have a long attack time.
Maybe you also have some value set in the Shift parameter?

Gianpiero,
If you have a daw, it might be worth dropping some cognitone drones onto daw tracks and using the relocate function to move the vsts from the engine into the daw.
See if this creates the same level of latency. If t does, then try dragging the midi out of the drones onto the tracks themselves. You can then see if the midi notes are in the correct timeframe.
Doing this will help diagnose if the problems synfire taking time to work out the notes to play, the engine adding a delay or if the arrangement is producing late midi notes.

hey guys thanks for the suggestions
I have not tried drones in DAW and it could be a good idea to understand and isolate the problem
I do use ASIO driver and I tried to switch between ASIO and windows drivers but I did not hear any difference.
I will report back as soon as I got news
cheers

All instruments hosted within the same host should never show any timing differences against each other. They are all synched to the same clock at sample precision.
I'm afraid I still do not understand what exactly you refer to with "latency". Is that response time when playing live (midi through, monitoring)? Or timing against other instruments during playback? Or the playhead display on screen (graphics delay)?

I'm not refering to playing live latency. Actually when I play everyhting seems to be in time.
I'm talking about, as you said, playhead display on screen (graphics delay and sound of course).
So everything(all vst) is ahead of the time measure. Of course since ALL vst are ahead they are in time with themself
it's just graphic-sound delay

Pressing the Reset button on Audio & MIDI Setup window should also recalibrate the synch between graphics and audio.
