Garritan Personal Orchestra problems in Logic?

Hey there,

I have recently purchused Logic Pro and have begun using GPO with it. After installing the GPO update i managed to get it to show up in the AU units but now i'm having a problemwith getting the samples to play back the same way i play them in.

When i'm playing midi data into
logic, everything sounds fine but when i play it back it appears to be only
playing very short utterances of what i played. For example, any note longer
than a crotchet played on a violin sample still plays as a crotchet, despite the
edit windows diplaying longer note values. Instruments such as the harp don't
cut off because they're percussive in nature i guess but any instrumetns that
need to be held down for sustained notes are affected. Not sure whether this is a common problem in many sequecners but it seemed to work fine when i used cubasis on the pc.

I have a score to do for a show in the Edinburgh Festival so any help would be much appreciated!

I saw this post (below) from iSchwartz and not sure if it's related. I have a touch responisve midi keyboard going through a M-Audio Audiophile interface into my new iMac. I think other midi data is also being affected so it must be logic rather than GPO. I'm still getting used to the programme so apologies if my explanation isn't very clear or if i'm being stupid!

Hi Patrick,

I bought GPO not long ago. There are some very good samples in there, my particular favorites being the harps and the solo violins. But there are other great samples as well.

One caveat, tho, and something I wasn't aware of at all when I purchased it... The stock instruments are not velocity sensitive in the traditional sense. In GPO, velocity controls attack time while the mod wheel is used to control velocity+brightness.

For me this setup was a totally counterintuitive way of working, and at first I hated it. Then I found it to be a useful way of working when playing, for example, the solo violins. In the end, there is something to be said for having volume/brightness affected by a continuous controller, but I still haven't gotten used to adjusting an instrument's attack with velocity. But the modwheel volume+brightness control lets you achieve dynamics (cresc/dim) on long, continuous notes, something not easily achieved any other way.

On the flip side, you can download a velocity-sensitive (in the normal way of thinking) set of instruments from the Garritan website. They solved my problem for most of the patches. I still prefer to perform my parts using normal piano technique, though I'm starting to warm up to the idea of using their original instruments for certain applications.

Hope that's not too confusing.

Its length of notes, not velocity that i'm having a problem with so not sure if there's any relation here.

Hope to hear from anyone soon!

Thank you!

Hi Blair,

iSchwartz here 🙂

The only thing I can think of is that you have the gate time of your various tracks set to something other than "inactive" (represented by the "-" mark). To locate this parameter, click on any GPO track and then look at the upper LH corner of the Arrange window for the realtime parameters. These include velocity, delay, tranposition, loop, and... gate time.

If this parameter is set to, say, 50% (for example), then whatever you play or record will sound right as you're playing it. But playback is affected. In this case, the length of your notes (the "gate", or, the time that a note is pressed and held -- as it was recorded) will be reduced by 1/2. At more extreme settings, long sustained notes will simply "blip".

If this is the problem, simply check each GPO track and set the gate time to the "-" setting.

If it's not the problem we'll have to look elsewhere.

Post again after checking this parameter on every GPO track and let me know if that's the problem.

Hello Blair,

how fast (GHz) is your new iMac and how much RAM do you have?

The exact same problem you were discribing (harp etc. playing just fine, sustained notes from strings etc. being chopped off) happened to me last week while working on a crossover pop-classical arrangement.

The only difference between our cases is, that I was using all VSL instruments.

What saved me, was the freeze function. Freeze every track (you can always undo this track by track for further editing), and frequently "Refresh Freeze Files" (in the Audio drop down menu). This is important: Only after I refreshed the freeze files everything started to play back without a glitch.

Try it. Hope it works and good luck!

P.S.: Of course iSchwartz does not run into these limitations with his (what was it again?) "Dual Quad G5 and 6GB of RAM".

Heya everybody. Sorry for not checking back sooner, i've been away for a while but tried out your suggestions as soon as i got back. Looks like iSchwartz was right! I set the gate parameter to "-" and it sorted it out! Fantastic! My iMac is newish but just before the intel based one i think. It's a 2.1 Ghz PowerPC G5 with 1.5 GB of DDR2 SDRAM. Garritan seems to be working fairly well, as long as freeze tracks if using lots of instruments. I'm just about to install Garritan Big Jazz band so will hopefully go trouble free with that as well.

Thanks again! So nice to have this forum for help! 🙂

Blair
