MC5 vs MC5LE

are you selecting different patches in soundcenter?

I don't know a lot about MC5LE, it might only have one patch available.  but if not, you have to double click on a patch to "load" it.

soundcenter is not a "plugin" it's a softsynth - those are different things.  look for it in the INSERT>SOFTSYNTH list or in the SYNTH RACK VIEW.

I don't remember if the staff view has a percussion clef, but I'm thinking probably not.  the notation in MC is VERY limited.  if you want good notation you really have to go to a notation program like sibelius or finale'.

the lack of notation doesn't surprise me at all for an LE version.  if they didn't have PRV then that would surprise me.

Firstly, I would like thank all of you, and am very impressed at the great and quick support this forum provides!

I had done, as suggested,( i.e., changed the cloned SoundCenter track to different midi channels). They will play independently (if you first highlight the track being accessed) but when the sound is changed on the original instance, by clicking the drumset Icon, both of the SoundCenter tracks get the same sound.
You do not get the SC menu if you click on the icon of the
cloned track.

I could only insert a soft synth on the audio track of the cloned SC track in the Add Effect section, but it doesn't seem to generate the chosen synth's sound. 

INSERT>Softsynths  does NOT have SoundCenter listed.

Yes there is no Staff View in LE, but there is PRV.
I am glad to hear the MC5 full version has Percussion View.

Here is history of installation of MC5LE on my computer:
I first installed MC5LE v5.0.6.3 (part of the Instant Popstar package) and then registered it.
I stupidly downloaded the 5.0.6 Update and installed that,
which caused MC5LE to become unstable.
So I then uninstalled MC5LE.
I next reinstalled MC using the Start>All Programs>Instant Popstar>MC5 LE Setup.
The version I have on now, does not have a way to
register it when I click the Help tab.  I assume I am stuck on a Demo status?
Should I deinstall everything (including Instant Popstar), and install everything again, using the Installation CD?

Sorry for all the questions, but I really appreciate the help.
Thanks again.

Thanks Beagle.
Version 5.0.6.3 LE was unstable AFTER the update, in that the program froze, as well as my mouse.
I actually reinstalled it twice from the Instant Popstar.
The first time, it would freeze and not initialize after I selected a file to open.  I think ASIO4All was the problem.
I deinstalled ASIO4All and MC5LE, and the next time I installed MC from Popstar, it worked.  I haven't reinstalled ASIO4all yet.

I think I figured out the SoundCenter issue.
My MC5LE should (according to the manual) show up
when you click "Add Track>Instrument Track", but it doesn't.  I even checked my Vstplugin folder and SC is there in a Cakewalk folder.

Here is a way I figured out, to have multiple SC with
independent patches:
Insert>Insert from Track Template>All>All Instruments>(you get 12 choices incl. Analog Clav, BuzzyLead, Classico Bass, etc.)  Once I make
an instrument selection, I get the same message "IDS_GENERIC_ERROR not found in text resource file!",
but you get a new instance of SC.
You will not hear anything, so must click the track's icon
and SC will open up so you then make a patch selection.
Also, when I first get the new SC track, I set the Midi
input and Midi CH, and for "Output To">Selected Track Outputs>Midi Output (to the next SC number).

Yes, it's convoluted, but it works; and it doesn't look like I have any other choice in my present installation, unless
someone could suggest something simpler.

The update, has nothing to do with Instant Popstar, and was only downloaded from the Cakewalk site and installed.

Instant Popstar is actually a bunch of audio loops of played instrument parts, that work in MC5LE, so one can easily piece together a backing track to sing along with.
So there are two parts that come with it, the Popstar loops, and MC5LE.

Thanks for the information regarding the SoundCenter
defective installation.
I will deinstall Everything - the Popstar loops, MC5LE, and make sure the Cakewalk SC folder is deleted from the VSTplugin folder, plus anything related in the Documents Application Data folders.
Let's see if this "fresh" complete reinstallation works, and if not, I'll ask Tech Support.

Thanks again.

Maybe a good case for System Restore?
