Oddy-Free

Oddy-Free free software-synthesizer by Roberson Audio Synthesizers

Oddy-Free is a free software synthesizer developed by Roberson Audio Synthesizers. Available format(s): VST for Windows.

Oddy-Free is an emulation of an Arp Odyssey Mk.II – much attention to detail was given in the layout of the signal path to have it behave as accurately as possible. 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.

number stations for Ronin

number stations for Ronin free softsynth-preset by blortblort

number stations for Ronin is a free software synthesizer preset pack for Ronin, made by blortblort.

Number Stations for Ronin by blortblort is free. It is a set of 18 presets for Audio Damage’s retired modular multi fx unit: You can get it here.

Some tools don’t get the love and attention they deserve. Audio Damage’s Ronin is one of those tools. Ronin is no longer available for purchase, but you can still take a peek at it here.

While Ronin IS capable of much MUCH more than the 18 presets in this bank, the concentration here is on …unusual… delay application.

‘Number Stations for Ronin’ by blortblort is free…

Please download these and have a go… please put a limiter on your track when you test them. I eliminated all runaway feedback loops, but there ARE still a couple of presets that may get “pointy” depending on your input signals, etc. Better safe than sorry.
