Doepfer

Hi,

Thanks for the interest. I don't have a web site ATM, I'm way too busy 
building stuff. I've loaded some photos to the Yahoo Photos - Allan J 
Hall folder, they are a bit small but hopefully you can make the stuff 
out OK. If anyone wants to host larger versions I'm happy to send the 
files and some info.

I usually put these modules into a separate G6 case and fit a +/-15V 
PowerOne power supply and Oakley power buss rails. Panels are designed 
in Adobe Illustrator, panel blanks from Schaeffer and front panel 
legends applied using lazertran waterslide panel transfers laser 
printed from my Illustrator designs. This is a lot of work and not for 
the faint hearted!

My favourite modules at the moment have to be the P3 Sequencer by 
Colin Fraser and the Infinite Melody generator by Ken Stone, mine has 
3 Diatonic converters added and a transpose input so I can play it 
with a keyboard too, all controlling three separate VCO's in 
controlled randomness - it's one wild module :-)

Also pictured is the Russian Polivoks filter that I cloned from my 
original Polivoks (the Russian Minimoog), interesting thing about it 
is it uses no capacitors in the design but instead uses the reduction 
in gain bandwidth of a programable op amp. This gives a real ripping 
sound when high levels of resonance are used because the resonance is 
a square wave rather than the usual sine wave - yummy! It works on +/- 
12v too, so it would be a great one for Deiter to add to the A100 
range. Marc Bareille developed my clone into MOTM format and sells 
pcb's. http://m.bareille.free.fr/modular1/vcf_polivoks/vcf_polivoks.htm

Other interesting module is my VCS3 - it has a genuine EMS Mk1 
oscillator board behind the front panel which has stability and 1v/oct 
mods as per Graham Hintons suggestions. I use it with Analogue Systems 
Trapezoid EG/VCA and AS EMS Synthi Filter to get the rest of the VCS3 
functionality.

Also my very mad TR606, most modded in the world perhaps? Built into 
6U Doepfer format.

Some mods to my Schaltwerk sequencer including a 1U Expander panel and 
trigger as well as gate outputs from a custom pcb, more details in 
Yahoo Schaltwerk group files.

Hope this is of interest, if it isn't apologies for the bandwith

Kind regards,
