ARP_Odyssey_VCO

Modular Version of the ARP ODYSSEY MKII/III VCO

ABOUT THIS PROJECT

Dreaming of my own modular synthesizer for many years, I’ve decided to finally start a DIY project. First of all I wanted to build a module which allows me to create sounds. I mean what’s the most exited thing about synthesizers? Right! Turning knobs, altering sounds and waveforms! 😉 Therefore I have chosen to build the VCO from an ARP ODYSSEY MKII. If you are not familiar with the ODYSSEY just head over to Youtube and have a quick listen to it. It sounds awesome! 🙂

ABOUT THE CIRCUIT

The great thing about vintage electronics is the availability of official service and repair manuals. I’ve found one for the ARP ODYSSEY online: http://www.arpodyssey.com/manuals/Arp%20Odyssey%20Service%20Manual.pdf

With the original schematics at my fingertips it was fairly easy to find the VCO section. I’ve used the latest version of EAGLE (7.7.0) to rebuild the circuit. My goal was to keep it simple by using parts which are still available and easily obtainable. I was able to get everything at my distributor of choice (www.reichelt.de). The VCO operates at +/-15V. It might be possible to use it with +/-12V to create sounds, but at lower voltages the CV-tracking will be most likely inaccurate. This thread over at electro-music gave me a few ideas on how to design my front panel: http://files.electro-music.com/forum/topic-54502.html

BUILDING PROCESS

Have a look at the wiki for further informations on building this module.

IMPORTANT

I have not created the schematics for the ARP Odyssey MKII/III VCO. I have just reworked the layout for all the DIY synth builders out there.
