Lolatu, is your computer system fairly spec'd? At least i5 processor, SSD, and 8 GB RAM? What you say you're experiencing, is one of the reasons, why I'm still living in Few-gigabytes-samples city.

I have't used the full version but as far as I know it always maintains two sets of samples (close mic and far mic) that you balance with sliders. This doubles the RAM and SSD usage compared to Lite which only uses the close mic sample set.

Then, you need to really review your computer settings. Especially if you're on Windows. There was a link somewhere on Focusrite website with Windows tweak you need to do in order to improve your low latency audio stuff.

Then you need to play with your ASIO driver latency and choose the lowest one where there are no crackles. People sometimes try to set to small a buffer which isn't really necessary. A size of 128 or 256 is more than enough.

Furthermore, on the CFX advanced page (OTOH) there's a setting about how much RAM to use for prefetch, meaning how much memory to use for loading the beginning portion of each sample into memory, while the rest is being read from the disk. By default it's 2GB but you can increase it to 4GB if you have 8GB memory, etc.

Then, make sure the master volume slider on your CFX is left at where it's by default. I tried to increase it initially and while it works most of the time with no problems, on some very fierce Chopin fortissimos I managed to clip it and it sounded like latency crackles though, so took me some time to realize is clipping and not latency issues.

BTW, I had to restart the CFX when changing latency settings on Windows.

Gave all those a try.

System requirements are, from garritan.com:

Microsoft Windows 7 or later -- yes, Windows 10
Audio interface compatible with ASIO -- yes, UR22
Multi-core processor required -- yes, quad-core Q9550
4 GB RAM minimum required -- yes, 4 GB
22 GB of free hard drive space required -- yes
A dedicated hard drive for CFX samples is recommended, but not required -- no
Drive speed of 7200 RPM recommended; SSD is preferred -- yes, SSD

I had it on my secondary 7200 rpm HDD to start with, but then moved it to the SSD after clearing some space. Seemed to improve things a bit, but didn't completely fix.

I'd upgrade the RAM and processor if I could, but I'd need a new motherboard, so it would essentially be a whole new computer - mucho dinero. I don't really need higher specs for anything else I do, and Pianoteq and Vintage D run fine.

I do have an i5 4GB laptop which I haven't tried yet, though I'd rather stick with the desktop since the laptop doesn't "live" by the piano.

If you get the Lite version, is there an upgrade option, and if you go that route, do you end up spending more overall? I think the extra mic positions would have a huge impact of the overall impression of the sound.

Morodiene, the upgrade is possible. On timespace.com it's £86.95, about 113 US$. Sweetwater actually has the full CFX at $159, so now is the time to cut cost, for those who want this VSTi, Lite or full.

Morodiene,
I have full. (I don't know anything about the Lite version.)
I highly recommend getting full CFX. well worth it. I think its my favorite piano program. there are some great presets. and I tried adjusting the Timbre knob. really cool.

Yeah I notice that on the Garritan store it's $200 for the full package, $80 for lite, and $100 for an upgrade. So cheaper to buy lite then upgrade.

Cybergene - thanks for the suggestions. I will continue to experiment.

I can definitely feel the difference between 64 and 128 sample buffer. Unfortunately also it's a global setting that I have to set within the Windows Control Panel so affects other VSTs. So would like to keep it at 64.

Funny thing - I don't know if it the same for other people, so please let me know. When loading a Full preset for the first time, it takes 62 s. I noticed the Antimalware Service Executable was running at 15% during this time. I turned off Real-time protection, and it took 16 s. Repeated the experiment and it was similar: 62 s and 12 s. (It doesn't seem to be the root cause of the problem though, since I still get the popping problem with it turned off.) How can I get Windows Defender to not scan these files every time I load CFX?

I have a hunch that the popping might have something to do with Windows memory management, since I have Max Engine RAM Allocation set to 1.25 GB, and currently CFX lite is telling me that it's using 1285 MB, but Task Manager says Aria is using 534 GB. I think Windows 10 automatically compresses RAM when it's running short, so maybe it's taking time to decompress it.

Start with doubling your RAM to 8GB. Relatively cheap and a decent chance of helping significantly with a RAM hungry application.

4GB is REALLY anemic by modern standards, particularly for a hundred-GB sample library. Are you sure you can't upgrade this? Upgrading to 8GB would be more in line with modern entry-level systems (even a new $500 Dell laptop is configured with 8GB default). I think this would make a huge difference not only for VSTs, but also general purpose computing.

Lolatu, I remebered it - you are right, it was Windows Defender messing with my system, hijacking my computer after 5 minutes of inactivity or something! Unfortunately I don't remember what I did to stop it but it was far from trivial and I had to do some registry hacks, etc. in order to completely stop it. Windows sucks great time! It was only that I had a spare Windows laptop that I dedicated to CFX and hidden in a drawer, otherwise I would have used a Mac.

I cannot imagine having another sampled piano now that I have ACD and Cfx Lite. What else is there? Maybe a good Kawai?

Seems like *reducing* this, and the Pre-cache amount, is helping a lot. I've got them set to 256 MB (default on 32-bit was 1.25 GB) and 16 kB (default 64 kB), and the pops seem to have gone. This would also explain why the 64-bit version was worse, since the default there is 2 GB. It'll be more intensive on drive access, but the SSD seems to be able to cope.

That would probably help, but like I mentioned, I'd need a new computer. Max on my motherboard is 4 GB.

Hot stuff in 2009!

As well as motherboard and RAM, I'd have to also replace the CPU, which is expensive, then work out how to transfer Windows 10 and re-install everything, a huge hassle. Not absolutely sure I want a desktop PC going forward - apparently desktops are going the way of the dodo. (Tablets as well, the cool kids tell me!) So a bit reluctant to upgrade at the moment.

It's not just that. Defender starts full scans of the system once it detects system inactivity for more than 5 minutes or so and that happens to be the case when you are playing piano smile It hijacks the CPU and you experience glitches. I had this problem on my laptop with Windows 10 and I had to edit the registry for that because there's no standard way of disabling Windows Defender.

The difference is curious : even if the 32bits and the 64bits versions use different register sizes to calculate the sound, 32bit is more than the audio card resolution and the extra precision should not be heard.

If you have two versions, it is because a 64bits DAW can't directly load a 32bits VST and a 32bits DAW can't load directly a 64bits VST. If you want to do this you will have to use a bridge : explicitly with some DAW or implicitly with others (Reaper...), but such a bridge has a performance impact (you have 2 different processes which have too exchange some data).

Lolatu, I have a light laptop that had the same pops. Those seem to be latency issues which might be addressed via a few system tweaks.

Plenty of studio pros are running huge audio packages on 10+ year old computers so don't lose hope. It seems 4GB could be a bottleneck but you never know until you try. This is trial-and-error but a few easy ideas:

1. Download the free and easy to use LatencyMon software. This helps you measure and target latency issues. You will see what tweaks are working.

2. Fully disable Windows Defender and turn off your wifi. The steps below made a huge difference with latency. Other methods to address Windows Defender did not help much on my system

http://www.windowscentral.com/how-permanently-disable-windows-defender-windows-10

3. Easy tweaks in this quick guide:

https://support.focusrite.com/hc/en-gb/articles/207355205-Optimising-your-PC-for-Audio-on-Windows-10

3b. Easy (step by step) tweaks in youtube videos for Windows 10 by a guy who builds computer systems for audio studios

http://surfaceproaudio.com/

4. You might consider installing a "bloatware free" version of Windows 10. That takes a bit of time and effort if you have not done this type of thing before. Finding and updating drivers for an older computer is a root canal but maybe you have a lot of time on your hands and are good at that kind of thing

http://forum.notebookreview.com/threads/windows-10-creators-update-bloatware-free-edition.804247/

I wrote a blog on what worked with my system so that might be more helpful. There are a lot of great tips from the PianoWorld members:

I decided to but the lite version last night. I meant to buy the CFX last year but never got around to it.

Some things I noticed right away...

Neutral and clear tone. I adjusted the timbre knob down one and added the studio reverb.

The built in limiter does not work very well. I can still hear it peak and get adjusted. I turned the limiter off and I'm using a separate plugin which fixes this issue.

There is no knob for hammer/attack noises. You can hear noises at the beginning of attacks, especially when playing soft. This could be realistic, but for someone like me who has spent most of their time on digital pianos it is distracting.


I'm really happy with it though! Probably the best playability I've experienced so far.

If you're talking about CFX Lite, it is downloaded, but the full version is shipped in a box. So you should be able to get the Lite version, at least.

Edit Just checked Musicians Friend, and CFX full turned up as costing 1.358 SEK, think that's about £120, by applying the WELCOME coupon code. Shipping not included, I assume.

I just noticed the full version seems to be on sale too.

$59 for Lite, $159 for full (and $143 with the 10% off coupon). So it seems there's no advantage for going the Lite + upgrade route.

Dumb question from someone who doesn't use VSTs--will I need anything special if I want to run CFX full on a 2017 MBP15 (quad core, 16GB RAM, SSD)? I'm assuming the system is beefy enough that it'll just work, but I haven't really researched it.

Since I use Garritan CFX on an old i5, 8GB, I suppose your configuration will be happy with CFX. wink

The only thing you sould care is the audio card if you are sensitive to the latency.

That's what I'm worried about. If I can just plug a USB cable into my laptop and start playing, I'd be highly tempted to dip my toes in the VST pool (and I've heard enough about CFX to know that's the one I probably want). It's my work machine so I could even plug it into the DP at the office too.

But if I have to buy and lug around some external USB audio interface as well, it's probably not worth getting into ATM.

And I have no idea how sensitive I am to audio latency. I guess a good question is, do Mac users typically run CFX with an external sound card? Or do most get by with the built-in audio interface?

You don't need a sound card. Macs just work, they don't even need asio drivers.

Not the answer I was looking for, Gene. Sigh.

excluding it in Windows Defender.

Hey thanks - that worked a treat for speeding up the loading time. I tried both 1) excluding the folder containing the sample files, and 2) excluding the "CFX Lite.exe" process. Both worked, but the former reduced the time to 19 s while the latter reduced the time to 12 s, so it seems excluding the process is the best way.

Thanks a lot. I'll look into those if it remains a problem. It seems to be working pretty well now that I've reduced the RAM allocation. It does seem to be worse if I leave it for a bit and come back later, which supports my memory-compression theory. I'll continue to monitor the situation...

Yes, I just did so, and paid via PayPal (though credit card would surely have worked too). Not what the VAT situation is supposed to be, but it doesn't seem like I paid any. Anyway, worked out to about £45-50 so much cheaper than buying locally. Doesn't seem quite right, but then again, I wouldn't have bought it at the higher price (that's what economists call a "deadweight loss").

So thanks for all the help guys. I'm still wondering exactly what the difference is between the Full and Compact presets - apart from the fact that the latter load more quickly.

Also I'm wondering why the presets are all such a pile of rubbish. There's not a single usable one! They're all "hey look a weird sound", without even any attempt at something absolutely basic like "concert recording". With the "full" version, at least it looks like the presets have been composed with some thought (link). So I chose a couple of random presets and made some recordings, just for you guys!

Lolatu, I have a light laptop that had the same pops. Those seem to be latency issues which might be addressed via a few system tweaks.

Plenty of studio pros are running huge audio packages on 10+ year old computers so don't lose hope. It seems 4GB could be a bottleneck but you never know until you try. This is trial-and-error but a few easy ideas:

1. Download the free and easy to use LatencyMon software. This helps you measure and target latency issues. You will see what tweaks are working.

2. Fully disable Windows Defender and turn off your wifi. The steps below made a huge difference with latency. Other methods to address Windows Defender did not help much on my system

http://www.windowscentral.com/how-permanently-disable-windows-defender-windows-10

3. Easy tweaks in this quick guide:

https://support.focusrite.com/hc/en-gb/articles/207355205-Optimising-your-PC-for-Audio-on-Windows-10

3b. Easy (step by step) tweaks in youtube videos for Windows 10 by a guy who builds computer systems for audio studios

http://surfaceproaudio.com/

4. You might consider installing a "bloatware free" version of Windows 10. That takes a bit of time and effort if you have not done this type of thing before. Finding and updating drivers for an older computer is a root canal but maybe you have a lot of time on your hands and are good at that kind of thing

I wrote a blog on what worked with my system so that might be more helpful. There are a lot of great tips from the PianoWorld members:

Hello,

Finally, can you play with 0 audio glitches?

I have made all the tweaks possible on Windows 10 (definitely disabled Windows Defender, Windows updates, all the unessentiel services....).
Even with an extreme audio optimisation, I can not play without audio glitches.
And that seems not be related to the audio card, becase I can play 1 hour without problems with the CPU running at 10%. But some times, for some reasons, some Windows processes start to run and cause CPU spikes to 90% with audio dropouts.
That makes me crazy....

Yes, indeed, some processes just start from time time... Last time I had problem it was some .NET lib pre-cache or whatever BS it was called. I hate Windows so much!!! All my other computers are Macs and I've never had problems with them.

Hi Stamkorg,

I run Garritan CFX at 44.1khz with a buffer of 64 on my i5 laptop.

If I forget to turn off Windows Defender & networking, I might hear a few crackles per week.

According to Garritan's techs, you need to exit Garritan CFX say every day or performance will decline.

If you can run for ~1 hour without issues, it seems your system is fine but just needs some optimization.

- Run the free LatencyMon to provide you some clues about what might be causing your problems.

- Disabling Windows Defender using the following method was the only one that improved performance for me:

http://www.windowscentral.com/how-permanently-disable-windows-defender-windows-10

If you still have issues, feel free to post your full config here, in my laptop recommendations thread, or just start a new thread. There are plenty of very helpful people here.

==> Edit - what are you using for an audio interface? ASIO drivers?

It seems to me that the problem here isn't with Windows, but with the Aria software. I don't see how behaviour such as

can really be Windows' fault. I'm surprised Garritan even admit to such a huge fail with their software.

I was playing just now, switching between various VSTs within Cubase, and coming back to the CFX after playing instruments results in audio problems. And after waking my PC from sleep this morning, playing notes on CFX standalone resulted in weird screeching noises, until I restarted the application. So it's true, the problems occur mainly when coming back to the instrument after leaving it for a while.

Vintage D etc do not have these symptoms, and this time-dependence is not what we'd expect if the problem were caused by CPU use by other processes. So I'm pretty sure Windows Defender, the Internet, random updaters etc are not guilty for most of the glitches.

I think the Aria programmers need to take a serious look at this and get to the root of the problem. It doesn't affect other VSTs, and there's a manual workaround, which is to clear then re-load the preset, so it's fixable.

Incidentally, my tests didn't show any difference in load times with lower disk pre-caching levels. It seems that it loads the entire samples each time, then presumably discards all but the first part of the loaded data. Why not just cache these first segments on disk as a simple optimization? My Max Engine RAM is at 256 MB, and it should take only 1 s to read that from disk. That would make the re-loading workaround less onerous.
