Crumar Musical Instruments User Group.

Hi,

I'm new to this group - just acquired a defective Performer a week 
ago, found a broken divider chip, fixed a defective connection etc. 
Some questions to this great community:

1. I have ordered a copy of service manual for Performer. However, 
this only contains schematics and part list as far as I know. Is 
there an 'adjustment procedures' type of doc existing somewhere (like 
I have for Polysix or Juno106)? Can anyone share this info? A 'user 
manual' could also be useful if that exists.

2. Does anyone have an idea how the Performer sound samples at Mod 
Archive (http://www.modarchive.com/waveworld/soundstate.shtml) are 
created? Are they really dry Crumer sounds or have gone through 
external processing? Some of these seem to be stereo sounds which 
should not be possible with Performer... Anyway, I am worried as I 
can't get all of these sounds out of mine :)

3. What kind of cap or knob fits on the tuning pot on the rear side? 
My Performer came without any and the pictures I found on the net are 
too dim to figure it out.

4. Anyone has a source for front panel faders? For TDA1008? Data 
sheet for TDA1008?

Sorry for the long postings and so many questions. Best regards,

Margus

That's all i have found on the web about the TDA1008

Margus, I've downloaded all of the sounds from above and I'm pretty 
sure that most, if not all, of the samples you're talking about use 
the Performer as their source. HOWEVER, as intimated by the preface 
to these samples, they have been heavily modified by the use of 
external resonating filters, phase shifters, delay and reverb. It's 
safe to say that 85% of the sound you're hearing in these samples is 
caused by the external filter they've been run through. Some of them 
sound so early Tangerine Dream-ish that I'd bet they were run through 
Moog filter banks.

Great sounds . . . but not typically Performer. For one thing, almost 
no use of the Performer's filter bank is used . . . well, it's 
actually labled EQ Control on the Performer but still . . . whoever 
made the samples was more interested in transforming the Performer 
into something other than what it was, and not representing what the 
instrument is really good at.

Sounds like I'm a purist, doesn't it? Not really. I like these 
samples. But I wouldn't post them as "Crumar Performer". It would 
have been more acurate to have posted them as "String Pads" 
or "Filter Sweeped Strings" or something like that because they are 
mainly effects.
