I'm getting a crash to desktop using this patch both with on screen keyboard and my midi controller, I've tried reinstalling both unify and the patches but still get the crash after just playing a few notes

just found patch BPM-Seq 09 crashes after just playing one note C4 in this case

patch zBPM PAD - Endless Ocean, zBPM SEQ - Tears of Life, zBPM SYNTH - Obsessive Impulsive, it says the current patch has been changed when going to the next patch

win 10 pro, i7-8700k, 96GB ram, gtx-1070ti

@auntystatic

I'm working on an update to Unify which will fix this. I hope to have it out very soon.

It appears this bug has been in Guru Sampler for years, but we've never run into it before because of the way John makes sample maps. Bob Dedes does it slightly differently, and hence... Oops!

I switched to a new windows 11 pc and my cpu spikes with zBPM PAD - Endless Ocean all of a sudden without playing the patch it starts spiking and level keeps building up till its at 125%. This new pc is normally fine under load with latest specs (i9 14900k and 64Gb RAM). Is this bug fixed? And in which patch?

Please try the latest public beta, available at https://pluginguru.net/unify/beta-change-log.html.

Intel has begun following Apple in their move to asymmetric multiprocessing (AMP), aka Performance and Efficiency cores, and your lovely new Core i9 is part of this trend. The current shipping version (1.10.2) of Unify was not built for this, but the v1.11 is.

Our AMP testing so far has concentrated entirely on the Mac platform, so I would be VERY interested to know if you see an improvement on that PC, with this patch specifically. Please let us know.

Thank you for trying the beta, and for reporting right away. A few questions:

  1. What version of Ableton Live are you running?
  2. What is your sampling rate and buffer size for this project?
  3. Are you 100% certain you're running the beta version of Unify? (Open the GUI and check under the logo at top left.)
  4. Which beta did you choose? 326 or 324?

Your image shows "CPU 1" through "CPU 4", but your CPU has 24 cores. Also, core temperature may not correlate with load. It would be more helpful if you could find a way to show each core's current utilization. One option is to use the Resource Monitor app, and open the CPU graphs at the right-hand side, and set the view size to "small". A better option is to use some kind of CPU-usage widget, if your PC supports them.

Live 11.3.13 sampling rate 48000 /256

Yes running beta but installed it without restart

It says 320 version

True it has 24 cores, its just that I can see build it up en than look it the cpu getting real high and my watercooler is turning on. Without doing anything just loadiing the patch.

I will try tomorrow to make a better graph although I dont wanna fry my cpu's 🤣

Did you download the latest beta 326 from the Unify Beta Change Log page I specified? If not, please do that, and unzip the WIN_Unify_1-11-1_Beta326.zip archive to a new folder.

Unify should say "BETA v1.11.1/326" under the Unify logo. If not, please try running the UnifySetup_RevertTo_1.10.2 installer that came with the beta, then re-run the UnifySetup_1.11.1 installer. Note neither installer will work correctly while you have any instances of Unify running, so please quit your DAW and/or the Unify stand-alone app before attempting to run the installers.

Once you have Unify beta 326 installed, please run the Unify stand-alone app first, to verify that it says "BETA v1.11.1/326" under the logo. Then please try loading the problem patch in the stand-alone, and tell me what the CPU meter at the bottom of the Unify GUI is doing. If there is no CPU meter displayed along the bottom of the GUI, click the concentric-circles icon in the bottom center (between the question-mark and exclamation-mark icons) and choose "Toggle CPU meters" from the pop-up menu.

@getdunne I didnt notice at first that it was a download link so I downloaded it from the site. I reverted it and installed the 326 version. At first glance it looked ok temperaturewise but after a minute or so it starts rising. See printscreen. I allso saw the cpumeter in unify rising.. I tried again standalone and it was stable for a while. Than I went to ableton and same problem ocurred. I thought maybe because I have many midi devices interfering eachother but that doesnt seem to matter.

Thank you for the update, in particular the Quick CPU screenshot. I had been searching for a good CPU-monitoring tool for Windows 11, without success, which is why I didn't recommend one earlier. Users interested in Quick CPU, please see below under the dividing line.

The patch in question, zBPM PAD - Endless Ocean from the Modern Cinema - Ambient Dreams library, is definitely a complex one, featuring 13 INST layers, of which 11 are embedded Unify layers, for a total of 58 layers. None of these layers is particularly demanding, however, as most use just one instance of Guru Sampler, and even the total RAM load is under 4 GB. It's a bit surprising that Quick CPU is showing about 25% CPU utilization on all cores. On my AMD Ryzen 9 7950X PC, running this patch in the stand-alone Unify app, overall CPU utilization sits around 5%.

  1. Did you take the screenshot while running the Unify stand-alone app, or Unify in Ableton Live?
  2. If in Ableton, please repeat the test while running the Unify stand-alone app only.
  3. Please provide one screenshot when neither Unify nor your DAW are running, to provide a baseline for comparison. (You can zip several screenshot files together, and attach the zip to your comment.)
  4. What type of audio interface are you using, and are you using an ASIO driver for it?

You definitely don't seem to be getting great CPU performance from your new PC. It would be nice to get to the bottom of this.


Quick CPU is a free CPU-monitoring utility, and it seems to be a very good one. Unfortunately, "free" is rarely truly free, and the developer (CoderBag, LLC) has elected to stuff the product web page ( https://coderbag.com/product/quickcpu ) with fake (monetized) "download" links. To find the real download links, scroll all the way to the bottom to find the list under the heading "Release History". Most PC users will want to click the first "64 bit" link, BUT WATCH OUT--this pops up a FAKE "download" window which you must dismiss manually, and THEN the file (QuickCpuSetup64.zip, 33 MB) will download. As always, some browsers might require you extra steps in their attempts to protect you from malware. I can't guarantee that this utility is NOT malware, but I can attest that the program appears to work correctly.

Thank you for the second screenshot, which shows clearly that Unify's CPU meters are pegged at maximum on INST layers 2 through 8, and very high on INST 10. It looks like this was captured with Unify running under Ableton Live? Could you please capture another with only the Unify stand-alone app running (quit the DAW) with the same patch.

I attach a similar screenshot of Unify beta 326 stand-alone running this patch on my PC. CPU usage is dramatically lower.

@getdunne Hi Shane, well first of all I had no issues downloading coderbag, maybe my adblocker, but didnt see any monetized links. Site looks fine to me. To answer the questions. 

1&2&3The screenshot I've added was inside Ableton but happened on standalone allso. In the zip is a screenshot of the standalone.

4. Focusrite scarlett 18i20 2nd gen with focusrite usb asio. If its the asio being the cause I must say I've downgraded the Focusrite  asio software to a previous version because win11 is a pain getting the audio right. I had pops and crackles and took me a whole lot of researching to find the culprit. I can now imagine why people making music stick to win10. My cpu usage is way better though ihad Win10 I7/7700 32 Gb ram and with heavy load sometimes 70% and higher CPU usage and someetimes so high it crashes. Now its from 20% to 30% max with the same template.

The CPU starts low, than I play some keys and let it rest and after a while, within 5 minutes, cpu builds up and temp builds up

This certainly is a mystery, but I can tell you you're not alone. Many people--not just Unify users--have been scratching their heads about audio/CPU performance on these newer CPUs.

I realize that performance within your DAW is important to you, but it would be best to minimize the number of variables by looking exclusively at the Unify stand-alone app.

To eliminate the Focusrite driver as a variable, please go to Settings / Audio-Midi settings in Unify stand-alone and switch to the "Windows Audio" device type, then make sure the sample rate is 48000 (or as close as your hardware supports) and the buffer size is 256. On my PC, where I usually use a PreSonus Studio 1824c with their Studio USB ASIO driver, this doesn't make much of a difference to CPU levels, but I'd be interested to know what happens on your PC.

Also, Quick CPU has another very useful display option--a pie-chart view which you get by clicking the "CPU Workload Delegation" tab at bottom right. Could you please send me a screenshot of that.

@getdunne I play a lot online jams via ninbot/jamtaba  and I use keys/percussions/drums/guitars/vocals/loops so CPU matters a lot to me.. With windows audio 48kHz and 256 same happens . I've attached the pie

Your pie-chart looks OK. Cores 7 and 8 are more heavily utilized than the rest, but it's not like they're getting flogged to death while the rest sit idle, which is what I thought might be happening.

I don't have experience with the latest Intel processors, so I can't really even guess why your utilization goes up around 25%, when my Ryzen chip sits around 5%. The only thing that stands out in your screenshots is that you have "core parking" set to 4%, whereas on my system it shows as 100%. I wouldn't think this should matter under load, but perhaps you should try dragging that slider (bottom left) up to 100% and see if it makes any difference. Note the Quick CPU graphs are fairly heavily damped, so it may take a minute or two to see any change.

If that doesn't magically fix the issue, I'll have to assume we now face another version of the thread-scheduling nightmare Apple created when they introduced their own ARM chips on the Mac. It took the JUCE team over a year to address that, so it might take some time. I'll take the matter up with them. Thank you for your patience.
