Open Rolls (32nds) - RH Dominance (Pulse)

Finale 2007
Windows XP
Pentium 4 HT
1.2 GB RAM

I'm finding that open rolls in 4/4 (32nd notes) sound very uneven . . . There's a heavier eighth-note pulse on the right hand.

In Finale, the midi velocity settings are the same for each hand (-63) . . . but the RH comes across as heavier . . . thus making longer open rolls sound uneven.

I'm using the Smart Playback plug-in (overriding Human Playback).

I tried to experiment with editing the midi velocities in Finale . . . but for some reason, with negative (-) numbers, they return a value of zero . . . when you go back and check them after editing.

Any suggestions to make the rolls sound more smooth?

This is a somewhat imperfect science since different velocity settings will trigger different recordings. For the most part, this wobble isn't too noticeable, but there are times (as you've discovered) where if your dynamics aren't going anywhere, you'll notice some imperfection. Since there are 127 levels of velocity control, you might find it helpful to try nudging the velocity setting up or down a few clicks, thus triggering a new combo of samples. There will be some fairly significant changes to velocity control and sensitivity in the upcoming update that might help this automatically.

What do you mean by using negative velocity values? You should�� be using a value setting between 1 and 127.

Jim,

When I check my velocity values using the Midi Tool in Finale 2007 . . . the default velocity reading is -63, for both RH and LH hits . . . for both snares and tenors.

On the other hand, I've found that I can notch the unison RH bass hits up to 127 . . . which is nice.

Let's be sure we're talking about the same things here...

#1 - RH vs LH in sampling can be more drastic, and should be to be noticeable.
#2 - A lot of the differences aren't so much amplitude (volume), but pitch.  See if that's what is bugging...
#3 - Live playback can affect velocity.  Make sure that you are indeed getting the same velocity.  Often, programs like Finale and Sibelius alter velocity by as many as +/- 6 or 7 in order to sound ";real";.  That may work for a clarinet, which gets maybe 20% louder from mf to ff.  Percussion samples are much more sensitive to smaller changes.

Mark, are your midi settings any different with your triplet passages?
Interesting... I was using the perceived RH dominance as a way to train my ear as to what my HS line would sound like...

So, there's not supposed to be a RH pulse???

Well, ";very"; is stretching it . . . There's just a noticeable pulse on the right hand.

It only sticks out for me on 32nds in 4/4 . . . but my triplet rolls are sounding nice.
