accomponied with Maxthon Browser
It's onboard sound.
It runs when Maxthon is not running
Analog Devices MIDI-Synthesizer
  Rolf Müller   (further information)
Part of the MIDI subsystem for the SoundMAX range of Soundcards.
is run by certain apps requiring special sound emulation
In my case, it was disguised malware- a keylogger and something else.
It's the midi driver for my laptop's sound chip
used by soundmax soundcard
Legitimate part of Syntrillium Wind Chime for your dektop. Syntrillium is no longer in business.
If you have SoundMax onboard audio, and you have accoustic environments turned on, it will run syncor.exe, will post more on our tech pages,

Media players use it for midi files. But WMP leaves it in place, then I can't play other formats. Other apps dump it as necessary.
AVG reports as harmless
It, in itself is not dangerous, it is part of a driver package called Soundmax by Analog for it's motherboard chipset. It can cause problems by cycling in XP, see your system manufacturer.

it plays my real player. when i deleted it, real player stopped working
Installed with Analog Devices SoundMax for onboard soundcard. Behaves as expected - no suspicious network or IO requests, file date matches, etc...
has been automatically install right after opening some shady webpage...
SynthCore COM Server from SynthCore 3.0.0 by Analog Devices (SoundMAX MIDI Synthesizer)
Midi files won't play without it
A subprocess of windows media
maybe something about sound

I also have a SoundMAX onboard system, but why should this file block access to a folder I want to delete?
used by SoundMAX needed to play midi files
Causes my machine to freeze for a short time right after connecting to the internet
Appeared in my sistem after installation of RealPlayer. Seems non-harmfull, except of Real-Time process priority.
This is a required midi component file for most of, if not all, products in the Analog Devices SoundMax line. If you see this entry in your task manager, then a midi is being played locally on your computer; don't stop it or else you will no longer hear the midi, and the outside app that requested it (like WinAMP or WMP) may crash if you do.

As Robert said. Runs MIDI. Part of soundmax soundcards. I only noticed older games make use of it. Harmless
It's a virus!!!!

Best practices for resolving syncor issues

A clean and tidy computer is the key requirement for avoiding problems with syncor. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
