Elektor Formant Modular

Hi to you all,

My name is Kris Bishop, 25, Scottish, Studying Electronics and 
Computing Engineering. Been playing synths for 15 years but never a 
modular. I own Yamaha CS1X, Korg MS2000, Supernova, Korg ER-1, Es-1.

Well I'm in my final year and have been asked to design an digitally 
controlled analogue synth. To save on time I am recreating the 
Formant.

I've read posts about it being hard to recreate due to lack of 
parts, however I should be able to overcome this problem.

Although I have a copy of the book from the net I drastically need 
the original as I feel some parts are missing. Can anyone tell me 
the name of the books and if possible where to buy them.

At the end of this project, May 2005, I should have a fully built 
digitally controlled Formant. Also the board I build will be able to 
be rebuilt by anyone as I will re-do the board layouts where 
required.

Cheers
Kris Bishop

Hello Kris.
 
Dont Forget that a small number of components in the origonal design 
are now obsolete, if I remember right they were obsolete when the 
design was published, there were several mods published, mainly for 
the VCO's and VCF's, because a temperature regulated opamp from 
Fairchild was not available, I think these mods appeared in the 
Formant book.

I'm hoping that I will be able to find some of the components and 
where I cannot I will modify the design to use up to date devices. 
For my first build however I'm going to try and build to the 
original specs.
But since I'm still learning electronics at university I might make 
some mistakes so I dare say you'll here my problems.

Cheers
Kris

I like your tune on your page.
I will look into the asm, but my main aim from this project is to 
understand why the synth works and how it was designed and how I can 
improve on it. Hence why I picked the Formant. I'm doing spice 
modelling on the formant just now and having issues with the VCO. 
The wave shaper works fine but my oscillator fails to start. I used 
my own CCO to calibrate the waveshaper just to confirm the design. 

I'll let you know how I'm getting on in about 3 weeks. Loads to do. 

Cheers mate
