It works! somehow...

[Matti E. Leino]

I have finally finished my synth project. Well, it,s not quite ready
yet, there's still something wrong in it...
I call it PG-101. The name comes from its project name, Project Groove,
and 101 comes from monophonic and it's first one.
So, what's in it? Well here's the list from all modules I have out on
it:
 - Two vco4d from TomG.
 - Two lfo's, lfo2 and lfo3a from Tom's cookbook
 - vcf8d, again from Tom's cookbook. MS-20 type.
 - vca1a, surprising, again from Tom.OBX type
 - Two env2b envelope gens from Tom
 - Ring modulator. This one is from JH.
 - Sub octave gen. from Tom. How surprising....
 - d-beam modified...
 - Mixer, some kbd controls, and headphone amp. These are my own
design...
It also have to external audio inputs, so I can play whatever I want
trough filter and amplifier.
I have put all modules in 6 unit high rack enclosure, and hardwired all
modules, so no patch cables are needed. I don't know is this good idea
or not, but I think it's good for me. Front plate is made from aluminum,
and text and figures has been "painted" on it..."painted" is not the
right word actually, but I'm so tired at the moment I can't remember the
right word. But I believe you know what I mean...

So, now it's  good time to thank Tom and Jurgen and all of you. It's
nice to know if I have some problems or something, I know how I can get
help. Thank you!

I'm planning to put some pictures from it on my webpage, but I don't
have digi camera or scanner available at the moment, so it have to for a
moment.

But I also have so problems with it. CV has no effect on VCA, gain is
high all the time. I think transistors that controls the gain current
are broke. But I haven't looked it closer yet...maybe tomorrow.Or day
after tomorrow...I don't how does VCA's envgen work because of
that...Also portamento and cv-mixer doesn't work, I have one broken
opamp there...And I haven't wired ringmodulator yet.

But still, I was extatic when I first time turned it on and heard
earthquake-like bass coming from it. And after little tweeking, a nice
whistle and sweep and all. Nice...

Well, gotta go to sleep for a while, just wanted you to know...And
thanks again for all!

 - Matti
