HI Guys
I Have Problem When I Want Play String Staccato Technique With My MIDI Controller
When I Play Note Like C-C-C With Tempo 140 The Sound Is Very Very BAD
It's Like Not Fit On TEMPO.
I Think It's For Round Robin
So How To FIX????
I Use The Great Sample Like Project Sam Orchestral Essentials Or Symphobia.

 

Sounds like it could be latency. In your audio device settings try setting the buffer to a moderately low number. The lower the number, the less latency you will get and vice-versa. If you start getting cracks and pops with a low buffer setting, increase it gradually until they are gone.

 

Also check to make sure you don't have midi input set to quantize in your DAW

 

You need to add a negative delay to your midi track (-10ms to -45ms).
Here's the deal, the faster the tempo the more you'll need to do this. The way staccatos are recorded, you get the attack of the sound at the start of the sample but you only hear the note a few milliseconds later. When you're at 60bpm it's not an issue but once you're running at 140bpmn, that little difference between the attack of the sound and when the note actually plays can be quite massive and requires some adjustment.
On this track I made for example, I had the violins (starting at 8sec) I and II delayed by 35 et 45ms respectively so that they are right on the beat, just keep delaying more and more (negative delay that is) until you find the right spot. .

ALSO, 140bpm might be TOO fast, you're not giving enough time to the stactatto sample to finish before a new one plays so you will get an unnatural sound. Maybe Albion I Spicattos could work at this speed but I'm very doubtful, 120bpm seems to be the limit. I think the only library that will give you acceptable 140bpm staccatos is Action Strings.

Hope that answers your question

 

Thanks.

 

What Zero-frag says.

Some companies, like Spitfire Audio, have purposely structured the sounds like that.

Quote from Spitfire manual:
"To maintain reality we cut our samples earlier than others. The start of a note often gives a sample its character. By cutting its
front off too much we feel you take away its personality. If things are playing back a bit behind the beat, even after quantizing
don’t be afraid of pulling that sequencer track pre-delay down a few dozen milli seconds."
