5.Click save and it should crash if not on the first try it will definitely crash on the second with those steps.

Hope this gets fixed, because I like to edit existing patches to make new sounds...
and I replied back to you, but still I can NOT reproduce it. I tested with 32bit version of Reaper, 64bit version of Reaper, but still both work just fine. I know this is frustrating for you (as it is for me as well), but if I can not reproduce a problem I can not fix it. I also reviewed by code, and saw nothing buggy in it. The only thing that comes to my mind is the Windows Open File dialog might be somehow causing a problem on your system.

Hello, I received your reply in email...it's still crashing for me, I'm also using windows 8.1 x64...the only time it doesn't crash, is after it crashes sometimes synthmaster upon reloading becomes very sluggish in the gui and and in this state it will not crash repeating those steps until you restart your computer and go through the steps to reproduce the crash again. I'm using Reaper x64 with the latest Synthmaster x64.

Also Synthmaster will not crash doing this in bridged mode, some DAWs use this method for vsts by default (Bitwig) running the plugin native in Reaper will allow this bug to be reproduced.

Have this problem too under BitWig 1.1.7 and it seems rather random.

Removing all preset information and/or saving to another locating then the default patch directory seems to work sometimes, but it's not really consistent.

How to fix this crap?

My brother said his Windows machine has this issue with other software like MS Office. We'll be debugging on his system next month.

Hi All,

Found this thread when looking for a solution to this problem, may have some information that could help.

My setup:
Windows 7 x64
Reaper 4.78 x64 (latest)
Synthmaster 2.6 x64 (latest)

To reproduce the crash I did the following:
1. Open Reaper
2. Add synthmaster to a new track
3. Open synthmaster GUI, click "save" or "save as"
4. Enter filename (doesn't matter where)
5. Click "save"
6. Crash - takes out Reaper as well.
This used to be 100% reproduceable, crashed every time I tried it.

Anyway, to try and troubleshoot a bit I tried turning off the "real time protection" on Microsoft Security Essentials (following these instructions: http://www.pcworld.com/article/2025707/ ... tials.html (http://www.pcworld.com/article/2025707/how-to-temporarily-disable-microsoft-security-essentials.html)) to see if this would help matters; it did! I could reliably save patches. Weirdly, when I turned the real time file protection back on, it continued to work (I tried it maybe 5-6 times).

Thinking that it was strange that it was still working even after turning the protection back on, I rebooted (leaving real-time protection on), thinking Synthmaster might start misbehaving again on a clean boot, which would give more evidence to MSE being the source of the problem. Sure enough, I opened Reaper, tried to save a patch in Synthmaster, and it crashed. The weird part is, I just tried it again, and now it's no longer crashing (with real-time protection still turned on).

So anyway, if anyone else with this issue has Microsoft Security Essentials, perhaps try temporarily disabling the real-time protection to see if it makes a difference; I'd be curious to know if anyone else is seeing the same behaviour?

OMG, I was guessing it was some sort of OS level issue. That's why I could never have reproduce it!

Thanks a million third kind!

Hi All,

I also have this problem. unfortunately the solution by third kind did not work on my environment.
But I found the other solution for this problem.
(I'm not sure why/when "Save as" problem occur. )

My environment:
Windows 7 x64
Reaper 4.78 x64 (latest)
Synthmaster 2.6.21 x64 (latest)

Solution (for Windows)
1. Exit your DAW.
2. Rename following folders. (like "SynthMaster_rename")
C:\Users\YourUserName\Documents\SynthMaster
C:\Users\public\Documents\SynthMasterTemp
3. Launch your DAW and load SynthMaster.
then the folders you renamed will be recreated.
(if you need, copy your preset(you created) back to Preset folder in the new recreated folder)
4. Now "Save as" will be working fine.

*. In my environment, if I load SynyhMaster as "Dedicated process", SynyhMaster seem to be stable.
To set "dedicated process" in Reaper,
1. Open Add FX window in Reaper
2. Right click on "Synthmaster 2.6 Instrument x64"
3. Click "Run as" and click "Dedicated process"
4. Load SynthMaster

I hope this information help someone.
Thank you.

I came back to post because for some reason I can't save consistently without a crash using the latest Synthmaster x64, even when I bridge the plugin it crashes. I tried both of the latest solutions from the last 2 posts and they don't truly fix the problem at all(just temp) and it goes back to crashing. I resorted to going back to the 32 bit version of Synthmaster bridged in 64 bit Reaper because it's more stable, but it uses more cpu.

I switch from Sonar to Reaper and if I use SM 2.6.21 64b in Reaper 4.78 64b, and save preset on SM, Reaper crash. It happen if I use all options how to use SM in Reaper (like dedicated plugin etc..). I need use MiniHost modular from ImageLine (Fruity Loops creators) it is free and Save preset is working.

drag731 · Post by **drag731** » Sat Jun 13, 2015 6:45 am

As DocShay pointed, the solution I posted is JUST TEMP. Now it goes back to crashing again in my environment too...
I think so too that the 32 bit version of SynthMaster is more stable.
so I quit to use 64 bit version of SynthMaster, I'll use 32 bit version.

I tried to debug this error to find solution by using some debug tool (x64dbg, ADPlus).
When the SynthMaster crash, the error message in debug tool says below.
I think this is kind of heap memory overrun error or mistake to release memory by HeapFree function (which is Windows API),
but I'm not sure what/where is wrong (it might be a problem of SynthMaster, Reaper, Windows or myPC specific problem...)

Anyway, I am able to run/use SynthMaster(32bit) without crash for now, (of cource I would like to use 64bit version if possible)
I'll go back to music creation. Thank you DocShay for telling me the workaround(using 32bit version) !

I just found this thread. I see I'm not the only one having this problem which just started for me today. I haven't tried any of the "fixes" above yet but I am going to.

Last time I had a problem with SM (it stopped working altogether) support told me my license had gone "bad" whatever that means. I am hoping that isn't the case this time. I will try the MSSE fix first and then move on to renaming the folders.

What a PITA. Only synth I have these problems with.

wagtunes · Post by **wagtunes** » Thu Jun 18, 2015 1:16 pm

The folder renaming seems to have worked, for now. But I'd still like to know what's causing this problem so it doesn't happen again.

drag731 · Post by **drag731** » Sat Jun 20, 2015 2:55 am

I found other solution for this issue.
(It might be just temporary working for now...)

[Solution]
1. Exit your DAW
2. Move to installation folder of SynthMaster. ex) "C:\Program Files\VstPlugins\KV331 Audio" for 64bit
3. If the folder "Expansions" is not exist, create it.
4. Launch your DAW and load SynthMaster.
5. Now "Save as" will be working

The "Expansions" folder is referred from configuration file of SynthMaster which located on C:\Users\YourUserID\Documents\SynthMaster\Config\SynthMasterConfig.txt (parameter name is "Expansions Root Folder").
The folder name or place might be different by your environment.
The point of this solution is that the folder which is specified by the parameter:"Expansions Root Folder" is EXIST.

In my environment, this solution is working FOR NOW...
(It might be going to go back to crashing again... Im not sure...)

I hope this information help someone.
Thank you.

Having the same issue and this didn't work for me. Also, it would be helpful if everyone commenting posted their OS, DAW, etc. (Not you drag731). That being said, renaming folders worked for me so thanks for that.

I'm considering switching back to Windows 7 if it starts crashing again.

Specs:
Studio One 2.6.5.30360 x64 (latest version)
SynthMaster 2.6.21 x64 (latest version)
Windows 8.1 x64

I am saying this once again: I can NOT reproduce this issue on any of my systems and therefore I can not figure out a solution. We have sound designers who work on Windows and they could not reproduce the issue as well.
