Looking for help with my Trilogy

Looking for help with my Trilogy

2005-10-13 by chitsujo

Hi, I'm new to this group and was hoping I could get some advice from 
the community:

I have a rather beat-up Trilogy that I've been tinkering around with. 
It has some problems that I've been working around, but I was hoping 
someone here would know if there's anything I can do to fix it 
without paying more than I spent for the machine (which was very 
little).

The string sound works beautifully, but it has problems with the 
organ and synth sounds.
With the organ sound, it makes a popping noise at the beggining and 
end of each key press.  The sounds are fine so long as you always 
have one note going, so I can work around that problem to some extent.

My main problem is with the synth sound. The volumes on some keys are 
significantly lower than the rest, most notably the D, E, and A flat.

I'm crossing my fingers that different volumes for each note is some 
adjustment I could quickly change inside the machine, but I rather 
suspect that getting this corrected will be costly.

Thanks for any help or advice!

Hi Chitsujo,
Maybe this could be of help to you: there's an article on sospubs:
The following passage is interesting:
Crumar made the Trilogy not 12x paraphonic, but 6x paraphonic. This means that all the Cs and all the F#s share a contour generator, filter and amplifier, as do all the C#s and Gs, all the Ds and G#s... and so on up the octave
So, now you might figure out which of the filters or ampilfiers aren't working properly.
Finding spare parts for a Trilogy can be hard; maybe http://www.vintageplanet.nl has the parts you need.
Good luck,
Ridzert

Hello,

it's been another while that i bought my trilogy ...
i cannot help specifically answer yr question, 
but what i can say is that maybe you just have to open yr
crumar & tweak the pots prudently/carefully ... it was like this 
that i discoverd one could tweak the maximum time of the attack & 
release of the envelope ... indeed !!!
right underneath the waveform selection , you have this pcboard
with some tweakable pots with numbers next to it: 

2 = length of the release parameter 
& 
14 = length of the attack parameter 

all the way on the rightside you have this 4 pots :

X1 X2
O1 X4

O1 = pitch
X1 & X2 make yr sound rawer ! some kind of ringmodulation effect

ciao ciao
