SKnote have released AnyTesla V2.0, available for only $29.99.
What’s new in version 2.0:
- Seta Red: This new parameter (added with v.2) adds a circuit around the transformer to bias the magnetisation of the core. The result is a different response on the low frequency range (where transformers affect the signal the most) with a wider sound palette. To hear its effect, focus on the very low frequency range while moving the control horizontally.
- Seta Blue: This new parameter (added with v.2) adds components to a negative feedback circuit around the transformer, giving control on the response to the mid-high frequency range. Completing “Red”‘s parameter action and combined with this, two new orders of magnitude are added to the overall dynamic palette. To hear its effect, focus on the high frequency range while moving the control vertically.
- Group Bypass: You can assign each instance to a group. When the group bypass is active on one instance (the menu close to group assignment) all the instances assigned to the same group are bypassed at once. This is extremely useful to check the overall effect of the transformers on the mix.
One of those powerful yet simple contributes to sound, input and output transformers.
AnyTesla models a couple of audio transformers and an optional power stage at its input.
The behaviour of an audio transformer is linear for small signals in a defined frequency range but starts deviating from that whenever the audio input approaches frequency extremes or starts being too “strong”. The signal is passed through the two coils of the transformer, through the magnetic core, thanks to an electro-magnetic interaction between the geometry of the coils and the core. The core can saturate, though, when too much average energy is transmitted. This is a special kind of saturation, really different from the level saturation we are used to, e.g. with overdriven amplifier stages. It is strongly frequency-dependent and for this reason often unique and useful.
One of the main positive effects of this style of saturation is to add harmonics to the lowest frequencies. This addition means they become a lot more audible, because, for psycho-acoustic reasons, we relate the step of the harmonics to their fundamental, even when it is not audible. More transformer saturation, more presence for low range on small systems. It also adds sustain without compromising the original dynamics.
A complete model of a transformer includes its effect on the driving stage (input coil), because when it starts saturating something is reflected to that side, too. The main effect is a reduction of the impedance seen from the driver, with all the possible effects on its output.
Design of transformers and materials used for their construction changed a lot with time. While more modern units are more linear and behave better in a hi-fi sense, they saturate less gracefully. Older units are less linear (they have some kind of effect on all levels and frequencies) but saturate in a more musical way. Different styles for different uses. Instead of talking about Physics and complex parameters, we grouped and interpolated lots of models under a single control: “Shape”. You can think of that conrl like going from “Vintage” to “Modern” materials and design, from smoother but less transparent to cleaner but with a stronger break-up and more harmonics.
One of the main design requisites for an audio transformer is its passing frequency band. The higher the starting frequency, the higher the frequencies that will be distorted with saturation. We exposed this parameter as it is a great control on the timbre and frequency range of the effect.
Features include:
- Sample-aligned Dry-Wet mix control.
- Mid/Side control, to balance the stereo field.
- Through-clipboard preset management system (copy and paste between instances).
- Macro, continuous choice of the style of the transformer (from vintage and smooth to modern and aggressive) under a single “Shape” control.
