DOES USING 2 OR MORE VST'S IN THE HOST DOWNGRADE SOUND QUALI

Hello friends I'm using a Dell Latitude with 500gb ssd and I have 16gb ram, quad-core processor but it's probably 8 years old now. When using Cantabile as my host I'm getting jumps, skips and clicks especially when I first turn it on. I have a BabyFace Pro as my audio interface. I like to use say Vienna Imperial in the first rack as my piano vst then in another rack use Miroslav or Project Sam to layer a nice orchestral background and sometimes I will even layer another vst with both of those. May I be pushing my system beyond it's capabilities or is the computer just wearing out? The processor meter is always above 100% but drops down to around 30% when just using 1 rack. By lengthening the buffer makes the sound quality way better but the keyboard response suffers. Any ideas? Thanks MooganDavid

Miroslav and Project Sam can be resource intensive. It depends on how many (and what) instruments you're using. By itself, Vienna Imperial isn't particularly demanding. It's older than your computer.

Perhaps you could try a DAW like Reaper. Various DAWs differ in efficiency when it comes to handling instruments. Some crackle and pop more easily than others.

That's my bet.

There may be things you can improve, but two VST's are probably using all the available CPU capacity.

A new computer might be cheaper than a full regulation of an acoustic piano.<g>

Agreed. Get a new computer.

You can try a few basic laptop tweaks.

- Check you have latest update of BIOS, drivers, Windoze, RME, VIs, DAW, etc.

--->Of course, the recent versions of Windoze 1903 have some reported DPC latency issues for music computers so maybe not the very latest is better. Some NSA backdoors have been discovered so Intel is patching some of these security holes; the NSA tax is more detrimental to the performance of older machines, reportedly (maybe 0-20% decline but some government shill will contest that here).

- Turn off all other programs you have running.

- Turn off all networking, bluetooth etc. on your laptop

- Make sure you are plugged in rather than using battery

- Select - Control Panel\All Control Panel Items\Power Options "High Performance"

- If your laptop supports "Dell Command - Power Manager" select thermal management and click "high performance"

- On the RME interface try increasing BUFFER just a bit. There is very little difference between say 48 and 64 (or 128 for that matter).

- On the RME interface and throughout your music chain, make sure you are running at native sample rates for the instruments (44.1KHz for Miroslav and Vienna Imperial). Resampling to different rate takes a lot of horsepower.

---> Per the respective websites, Miroslav is 16 bit whilst Vienna Imperial is 24 bit samples. I don't know if it would improve performance or matter if you have Vienna Imperial samples at 16 bit (or if the samples are even available at 16 bit). Frankly, I don't think there is anything we can do here with bit rates.

- Disable Antivirus programs (some methods are more effective but just do the quick way for now). Re-enable when you finish playing.

- If your laptop allows you to disable c-states and/or SpeedStep and/or turbo in BIOS that might lock your CPU speeds. This is popular problem for crackling music laptops (be careful to monitor that laptop does not get too hot).

- You could download free ThrottleStop software and try some tweaks to get your laptop sorted. You may be able to disable c-states, disable SpeedStep, disable turbo etc with that. You can also identify and kill idle processes so that c0% is below say 1%. The software requires some trial and error but there is a friendly forum.

http://forum.notebookreview.com/threads/the-throttlestop-guide.531329/

- You can download free LatencyMon software. Turn off all other programs. Let LatencyMon run for say 10 minutes. Look at results; DPC latency issues are identified by friendly graphic and detailed report.

Does using 2 or more capital letters in the title upgrade thread quality?
