*** Panic Report *** Please help me understand this.

The panic is a machine error issue. These are usually glitch errors that disappear when you reboot the computer. Have you tried that? I also notice you have a large number of third-party extensions, any one of which could cause such a problem. Here's the list:

• • com.paceap.kext.pacesupport.snowleopard 5.9.1
  • com.Cycling74.driver.Soundflower 2
  • com.Apogee.driver.DuetFWOverideDriver 1.4.4
  • com.shinywhitebox.iShowU-Audio-Capture 1.0.4
  • tc.tctechnologies.driver.TCNear 4.1.4 18150
  • com.digidesign.iokit.DigiDal 20.5.0f4
  • com.Sonarworks.driver.Sonarworks 1.8.11
  • com.LaCie.ScsiType00 2.7.0

I suggest booting into safe mode as outlined at the end. This will disable those extensions so you can determine if the panics cease. If they do, then one or more of the extensions and/or its software is causing the panics.

Dealing with Kernel Panics

Disconnect any third-party peripherals including any USB hubs. How to use safe mode on your Mac, Use safe mode to isolate issues with your Mac - Apple Support then boot the computer into Safe Mode: Use safe mode to isolate issues with your Mac - Apple Support and Playing Safe- what does Safe mode do? See Diagnosing problems- crash, freeze, panic, or spinning beach ball?, Don’t Panic! Understanding & Troubleshooting Kernel Panics in macOS, How to fix kernel panics after installing OS X updates | MacIssues, and If your Mac restarted because of a problem - Apple Support.

Kernel panics are indicative of possible hardware failure, so you should Check your Mac with hardware diagnostics or AHT. Kernel panic logs are found in: /Library/Logs/DiagnosticReports/ folder.

If you have no success figuring what is happening then you may need to examine the software you have running when the panics occur. Be sure it’s all current. If you must to resolve the problem erase the disk and reinstall macOS. Follow this outline to reset the computer to the factory-new state: Factory reset of your Mac - Apple Support.

Boot Into Safe Mode

1. If your Mac isn’t already shut down, then shut it down and wait at least 30 seconds before rebooting.
2. Immediately, at or before the chime, press and hold down the SHIFT key. 
3. Release the key after the Apple logo and progress bar appear.
4. Safe mode startup is much slower than normal startup, so be patient.
5. When the Login Screen appears enter your admin password. If you use automatic login, then this means you are in safe mode.

As for deleting those extensions, you don't have to. That is the point of booting into safe mode. It will help you determine if the panics are being caused by one or more of them. If it is, then you will need to uninstall them. You will need to check if the software that installed them have provides an uninstaller. If they don't, then you will need to do it manually.

Basics for Uninstalling Software

Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash.  Applications may create preference files that are stored in the /Home/Library/Preferences/ folder.  Although they do nothing once you delete the associated application, they do take up some disk space.  If you want you can look for them at the above location and delete them, too.

Some applications may install an uninstaller program that can be used to remove the application. If you cannot find the uninstaller then you could download the freeware, Easy Find, to locate files that need to be removed. The places you need to search include:

1. /Home/Library/Applications Support/ folder. Check if the application has created a folder then delete the folder that's in the Applications Support folder.
2. Applications may install a startupitem or a LogIn item. StartupItems are usually installed in the /Library/StartupItems/ folder or the /Home/Library/StartupItems/ folder.  Login Items are set in the Users & Groups preferences. Open it in System Preferences, then click on the Login Items tab. Select the item from the list and click on the Delete [-] button to remove it.
3. Some software use startup daemons or agents.  Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.

Some applications install a receipt in the /Library/Receipts/ folder.  Usually with the same name as the program or the developer.  The item generally has a ".pkg" extension.  Be sure you also delete this item as some programs use it to determine if it's already installed.

There are many utilities that can uninstall applications.  Here is a selection:

• AppZapper
• AppDelete
• Hazel
• AppCleaner
• CleanApp
• iTrash
• AppBolish
• AppUninstaller
• Uninstaller
