There are many that I already use in another program, Like Wusikstation32, Proteus VX, Kontakt 4,.. all 32 bit VSTis. Also, those others from HGFortune, and others.
Let me explain. Maybe I'm not doing what I should when loading a MIDI file. I go to the File Menu, click Open, choose a MIDI song, load it and it plays Ok with MC6. But when I want to change the sound and replace it with a VSTi, I click on a track, then on the Insert Menu/Virtual Synths (Cannot say how it is in English but in French it's "Synthés Virtuels", I have the French version.) It shows my list of VSTis that appears (with the missing ones not appearing of course

) but when I try to load one from there, anyone, the program crashes with a message popup notifying me of an error of exception (alas, too bad I cannot upload you a capture file of this message here), then asking me to save my file before MC6 closes down.
I will try to translate what is written on the message:
A fatal error has occurred. Module:C:/ProgramFilesx86/Cakewalk/Music Creator 6/Music Creator 6_EXE A Dump file on the incident has been created here: c:/Users/MyName/AppData/Roaming/Cakewalk/Music Creator 6/Mini Dumps/Title of my song_06192012_084344.dmp Exception code: c0000005 Address:004080DB:0018EA84:776DFACA Because of this error, Music Creator will have to close abnormally. Do you wish that Music Creator tries to save a recuperation copy of your work? (YES or NO) And That's it! Just by trying to load a VST, I had this appearing.
I hope it helps. Thank you!
