Roland System 100m

Greetings System 100massive,

I read through "Re: [RolandSystem100m] Silly newbie question, please help!!" which was 
uber-helpful.  After following the patching steps contained in the referenced post, I'm only 
getting a noise sound.  Sometimes, two to three seconds into the noise, I hear a gurgle.  I 
can control the envelope of the noise, but I can't change the timbre of the oscillator.  The 
only other sound I can get, if I set the resonance to the top, is a very high pitched lazer 
sound.  

I'm trying to figure out if my VCOs are broken.

Any suggestions would be much appreciated.

Gratsi,
armen
