In an another Forum someone Write, sample i write is Static and sounds Different from a Real vst. What does it mean? Can someone explain the difference if i draw a Standart saw in Sampler Editor or take vst with a Single saw. Why in Sampler Editor it is Static?
If you play a single sample per note in a sampler, the sample restarts from position 0 everytime you press that note and this can sound very static (depends on the used sampled sound), because the retriggered sound is always the same. The secret of a real synthesizer or a VST which doesn’t sound that static are the kind of oscillator they’re using. They are so called “free running” osc’s. Such an osc doesn’t retrigger it’s waveform from “phase” position 0 every time. This osc will be triggered from different positions everytime you press a note. This lets the osc sound more “liquid” or more natural. Then there’s the opposite of a free running osc: the static or “retriggered” osc. This kind of osc retriggers from position 0 everytime you press a note and it can sound static. Especially if you use a multiwave osc like a supersaw.
BTW: the word “free running” comes from the good old vintage synths and has not really something to do with triggering e.g. a software based osc. A real free running osc of a real old vintage analog synth isn’t really triggered by pressing a note. Pressing different notes just change it’s note pitch. The osc itself is everytime running, if you press a note or not, it still is running. Just it’s processed signal will be affected on note on’s/off’s by the amp envelope. So this osc doesn’t sound the same by pressing a note, because every time you hit a different phase position while it’s still running. And a Software based osc, which will be called “free running” just simulates such a real one by starting from different phase position every pressed note (and stops running the osc on note off’s), which is not the same, but quiet similar to a real one, just using another, a bit different method, but with the same result.
But you can also emulate a free running osc with a sampler. 1st method, if the sampler supports it, you let retrigger the sample from different positions in the first few ms of the sample. Or the 2nd method, realize it wit the so called “round robin” method. Here every note will be sampled several times. Every note uses more than one sample. Every sample sounds a bit different in the start phase (best way is to sample a synth with free running osc’s). If you now place let’s say 5 or 10 dfferent samples per note and enable round robin, then everytime you press a note, just one, and every time another of these samples will be played. This lets sound your sampled instrument more natural, more liquid and not static.
And just for info. You also can do this round robin method with the Renoise sampler.
