Strange EXS behaviour

Strange EXS behaviour

2006-05-17 by Hans Hafner

Hi there,

I have a problem with the EXS and at least here it's reproducible, 
perhaps one of you guys can test this real quick.

Download this song:
http://www.hanshafner.de/quickupload/piano_test.zip

It should already be in cycle mode.

Now hit play and immediately after stop and then hang on for 3 seconds or so.

I'm getting another sound and if the piano instrument I was using is 
actually loaded it's playing some sort of altered chord, some 
variation of the one that's coming later in the music.

Are you also getting this behaviour?

I've tested it in 7.2.1 and 7.2.0 and in 6.4.3 where it doesn't have 
this error.

Thanks for the help

Cheers
Hans

Confirmed. But it's not to do with EXS happens with EVP88 too.

Your quantisation strength and other extended sequence parameters are 
creating overlapped notes when played from a cycle. Chords that sound 
very slighty before a cycle are played from the exact bar the cycle 
starts in order to hear the chord, this sometimes plays havoc when notes 
are overlapped. It's odd that you are using Q-Flam, this is meant for 
notes that are already quantised - I think.

Hmm... perhaps it's that, however, I'm getting the "unwanted" chord 
when Logic just played for one beat or so and then stopped, does this 
still have to do with the cycle?

The flam parameter allows chords to sound more like a keyboard player 
would actually play them an not quite so static as a sequencer does. 
You're right, it sort of stretches notes out after quantizing.

But more to the point: in your opinion the quantize settings are 
responsible for the "unwanted" chord?

Thanks and cheers
Hans

I'd say a combination of the quantise settings and Logic's way of
dealing with playback and/or cycled playback when a chord starts before
the playback position. I think in this case the chord has some notes
that stop then start again (e.g E2) which seems a bit odd, as if you
lifted your fingers from the keyboard momentarily by accident during the
chord (not wishing to criticize your playing - that's quite normal).
These little notes aren't playing when played back from the cycle point
because I think the main chord is shuffled forward to sound from the
start of playback.

Update:

Just tried pasting the sequence into a new autoload and playing the same 
cycle. Doesn't happen - so maybe I'm talking rubbish and you just have a 
corrupt song!

I found the reason:

It's the chase setting. As soon as I turn it off of course I'm not 
getting long held notes, but at least then I'm not getting the 
erratic behaviour that I'm getting now.

So in my experience chase doesn't work.

Cheers

Aha, like I said earlier I had a similar problem a while ago but I never figured it out. Next time I guess I will disable the chase thing.
