Velocity problems
      #1022527 - 05/12/12 04:40 PM
Why is it when I set all velocities the same, they differ in volume ?

Im using cubase along with LA studio strings and I often come up against this...

I have also discovered recently that note lengths have different volumes ?

I use very little midi but would like to overcome this problem as it is something I frequently need to do..

Maybe the instrument is set to alternate between different samples to produce a subjectively more realistic result? If this is the case you might get slight (though this depends on the instrument and the manufacturer's quality control!) variances for identical MIDI note messages.

I don't understand what you mean here. The velocity of a note is set when you press the key; it can't be affected by how long you hold it down. Are you choosing different articulations with keyswitches or something? Or is there a volume swell during the sample?

I dont know if I am choosing different articulations ? Im just either playing notes on a keyboard or drawing them in from within cubase midi editor. When I play them in via a keyboard, they are not always played with the same pressure so i go in to the editor and adjust the velocities so they are the same, but some notes are different in volume and its totally random, I have no idea why ?

Does this happen when you monitor through headphones?

Maybe. First of all try sending the MIDI to a different instrument (one of the stock Cubase instruments, perhaps) to see how that behaves. Select a VERY simple patch - one oscillator set to sine wave, or something.

I've never used LA Strings - what hosts it? Kontakt Player?

LASS user here, maybe I can help? Sounds like standard deviations with string samples - sustained notes will have a slight swell to them. If you're playing staccato notes, then again, each one will trigger a different sample of that note, so you may get small deviations of volume.

However, LASS also makes use of CC7, your mod wheel, to control volume (as such the velocities themselves for legato don't matter much). Also, they use cc11 for an additional volume envelope, so maybe check 7 & 11 in your midi editor to make sure they're not inadvertently being sent.

Sorry, misprint. That should be cc1, cc7 being your volume control and cc11 expression, which in LASS is indeed mapped to extra volume control.

I don't know if the following is relevant for you... A string sample will not necessarily start at full volume but may take a fair few milliseconds to ramp up to full volume. In practice this can mean that if you are playing fairly fast (and, especially, non legato) lines, the sound will be subjectively quieter than when playing slower lines.
