Oddy-Free
The Roberson Audio Synthesizers interpretation of the Arp Odyssey Mk. II synthesizer.
From the Readme file:
“The absolutely fantastic artwork and GUI were done by androidlove and Modeler of KVR, many many
thanks to him as the synth just wouldn’t be the same without it.
Now onto business…
The Oddy-Free is quite apparently a emu of an Arp Odyssey Mk.II, and much attention
to detail was given in the layout of the signal path to have it behave as accurately
as possible. Granted it does have just a touch more umph than most originals would,
this particular emulation was based on the “illegal” filter versions based on Moog’s
-24dB Low-Pass filter, so it sounds quite a bit smoother and richer but at the same
it can produce the harsh metallic tones known from the Odyssey.
I really hope you enjoy the synth, I know that I enjoyed making it. It brings me joy to
release free models of synth emulations that otherwise one may have to pay out the nose
to get.
If you liked the synth and/or were able to find good use of it, please vote for me
and it as the number one entry in the KVR Developer Competition ’07.

Update Version 1.1
Changes:
–new face panel, a little bit of a more realistic touch.
–fixed spelling issues on face panel
–fixed masking problem with slider cap graphics, so there is no longer the black box
around the caps (rather nice fix, if you ask me.)
–added “analog” features, including oscillator and filter instability, along with a few
minor affects on related components, also a very subtle power supply bleed-over to
related components.
–added a slight filtering to the final output to reduce the unrealistic high end of the Oddy
just a slight amount for accuracy purposes.
–added voltage and amplification mods to waveforms to enhance edginess of waveforms
and certain modulations (you may need to correct previously made patches.)
–added user-made patch banks and individual FXP files for the Oddy, hopefully you’ll enjoy. 
–and probably some other things I forgot at 2 in the morning. 
Updated Version 1.2
Changes:
–numerous internal changes to oscillator structure, including totally different oscillators to begin with
–modified filter to behave differently and a little more “analog”.
–removed much pre-EQ in the signal path, making it a much easier to mix instrument
–removed older user patch banks from pack, they became incompatible with new oscillators and filter.”
-Update Version 1.4 *IMPORTANT*
-Made a few modifications, basic playability is largely unchanged. Most mods came in the form of filter modifications, it is BIG sounding now. Also, can resonate itself into oblivion, which itself can be dependent on what sample rate you are using, so BE CAREFUL. You’ve been warned. Some patches from prior versions may then have problems or may cause unwanted side-effects, so load them with caution.
