Hi,
I remember having an issue when installing Miroslav on my Win 7 64 for use in 8.5.3. I am now running X1 and Miroslav is working fine.
When I installed Miroslav, it was installed here:
C:\Program Files (x86)\IK Multimedia\Miroslav Philharmonik
I have my VST scan folders set to the 2 cakewalk vst folders:
C:\Program Files\Cakewalk\Vstplugins
& C:\Program Files (x86)\Cakewalk\Vstplugins
In order to get the Miroslav to work, I needed to copy 2 files into the (x86) cakewalk vst folder:
Philharmonik.dll
& Philharmonik.ini
The dll file could be found in your Miroslav folder. The ini is a configuration file I believe I found online some where (i didn't have it anywhere in the Miroslav install folders).
This is what is inside the ini file (copy this and save it in wordpad with the name Philharmonik.ini):
[VPA]
GUID={C60BC4DD-835B-4AC6-AFDF-8995E0468B28}
ChannelsIn=0
ChannelsOut=ASK
ID=1346908464
ProcessIndex=0
[VST]
Name=Philharmonik
Hope this helps.
