Ok, this is simple to reproduce. 1. Open reaper. 2. Create new track. 3. Insert Scaler2 VST. 4. Select C Major Hexatonic 5. Select “Keys Mapped” 6. Press C, D, E, F (which is locked out of the scale) … 7. Crash You guys need to learn about valgrind to cover all your memory access problems. ---

Looks like memory access violation. Valgrind wraps the program and pretests all memory access. Not sure how to use it on a library. It does not look the same as the link you provided which appears to be windows only. ---

OK, I confirm the case. Reaper 6.15 /64-bit Scaler 2.12 ``` Open Reaper. Create new MIDI track. Insert Scaler2 VST2 (or VST3 , the result is the same). Select C Major Blues Hexatonic Scale (probably any of them, I tried the first two) Select “Scale Notes Mapped” (if key lock is disabled, everything is OK) Press C, D, E, F (which is locked out of the scale) … Crash ``` * * * ![image](https://yyz2.discourse-cdn.com/flex012/images/transparent.png) **Error Event:** Faulting application name: reaper.exe, version: 6.1.5.0, time stamp: 0x5f8d893c Faulting module name: Scaler2.dll, version: 2.1.1.0, time stamp: 0x5f76e164 Exception code: 0xc0000005 Fault offset: 0x00000000002d2ae8 Faulting process id: 0x1ab4 Faulting application start time: 0x01d6ba24a9dfeba2 Faulting application path: C:\Program Files\REAPER (x64)\reaper.exe Faulting module path: C:\Program Files\Cakewalk\Vstplugins\Scaler2.dll Report Id: 9ab21c46-ac71-41b2-94d8-dfb129b7853c Faulting package full name: Faulting package-relative application ID: **Information Event:** Fault bucket 2237483524660157628, type 4 Event Name: APPCRASH Response: Not available Cab Id: 0 Problem signature: P1: reaper.exe P2: 6.1.5.0 P3: 5f8d893c P4: Scaler2.dll P5: 2.1.1.0 P6: 5f76e164 P7: c0000005 P8: 00000000002d2ae8 P9: P10: Attached files: \?\C:\ProgramData\Microsoft\Windows\WER\Temp\WER8B21.tmp.dmp \?\C:\ProgramData\Microsoft\Windows\WER\Temp\WER8C7A.tmp.WERInternalMetadata.xml \?\C:\ProgramData\Microsoft\Windows\WER\Temp\WER8CAA.tmp.xml \?\C:\ProgramData\Microsoft\Windows\WER\Temp\WER8CB7.tmp.csv \?\C:\ProgramData\Microsoft\Windows\WER\Temp\WER8CE7.tmp.txt These files may be available here: \?\C:\ProgramData\Microsoft\Windows\WER\ReportArchive\AppCrash\_reaper.exe\_a15f55ba17165d1f7c338e7fe13ea17c29f9857\_57a63214\_466db017-9590-429a-9bd7-826e10aae1f9 Analysis symbol: Rechecking for solution: 0 Report Id: 9ab21c46-ac71-41b2-94d8-dfb129b7853c Report Status: 268435456 Hashed bucket: 9ee80c7792372d41cf0d236936285cbc Cab Guid: 0 I have a video but cannot attach it to the post.

it seems that, at least in my case, the latest release fixed RAM issues: Scaler 2.1.2 sucks about 1/10 or less of the previous amount and seems stable and after having reconstructed the story of my upgrades and crashes, I think that my _not working_ Scaler was possibly the 2.1.0, certainly the 2.1.1 release, while Scaler 2.09 worked for sure ---

Im having the same issue. When keys are locked for using a particular scale it crashes The simple scales works fine but when I choose F blues hexatonic scale. It crashes instantly. In Reaper and LUNA both DAW its the same crash. By the way if I use Scales notes only it doesn’t crash but if I select scale notes mapped it crashes. ---

Same here. I just paid 50€ from this VST and haven’t been able to use it in Reaper 5.x or 6.x in Windows 10 at all. Longest time 5mins and then Reaper Crashes. No matter what audio driver I use. It seems quite major bug in Scaler 2. It even crashes if I touch the record button on the track that I inserted the Scaler 2. ![image](https://canada1.discourse-cdn.com/flex012/uploads/scalermusic/original/2X/c/c965833866b678da640eb614eea352c536cf2538.png) ---

Hi, I use Scaler 2.12 in Reaper 6.15 on Windows 10/64 bit and this happens only with C Major Hexatonic, but as I can see on your image, you use D minor. The latter is the scale I use very often (hm, I would say “too often” LOL) but I have no problems with it. Can you give some more details please? What are the steps to reproduce the crash ? Are there other specific VSTs that you use in the same project? I see you use Reaper 5.99/64 bit. In my test, I used quite a similar setting as you, except the synth on track 2. No problem whatsoever. Could it be Reaper or combination of Scaler + other VST? Did you try with just one track with Scaler and nothing else, then add another track? ![image](https://canada1.discourse-cdn.com/flex012/uploads/scalermusic/original/2X/6/64c5f753a5b03678d03efadc925ecdc077a886c9.png) Thanks, Mike
