EXTRA QUESTIONS
Meaning of FKFX
Feedback Effect.
The "feedback effect" refers to a situation where the outcome or result of a process influences the process itself, either amplifying (positive feedback) or dampening (negative feedback) its future behavior. This can occur in various systems, such as economics, biology, or climate, where changes in one part of the system trigger reactions that reinforce or counteract the original change.
Requesting Additional Features
Your feedback can help enhance the software you purchased and shape the addition of new features that may not currently be available.
Please email us at support@fkfxaudio.com and we'd be glad to add any desired features to our development plan.
About KrishnaSynth - History
KrishnaSynth was available between 2007 and 2010, but Devine Machine has since discontinued its development.
We have sent license keys to all former customers in early 2023, but some of the provided email addresses may no longer be valid. If this applies to you, please feel free to contact us at support@fkfxaudio.com.
The synth is a replica of the 2010 version, but much of the code had to be rewritten and the synth had to be beta-tested again.
Development of a version 2.0 is on our to-do list, which may include changes to the user interface. It is possible that the new version may be substantially different from the current version, but it will remain compatible with current version presets.
Important note about old presets : Using the old presets from 2007 version will most certainly crash the plugin randomly. If you have to reload them, please re-save them immediately after loading so the preset file structure becomes correct and safe.
Using Old Version Presets in KrishnaSynth
Using the old presets from 2007 version will most certainly crash the plugin randomly, because of an old defect in saving within the old version code.
If you have to reload them, please re-save them immediately after loading so the preset file structure becomes correct and safe.
Meaning of the "15" in the Plugin Name
This actually happened at the early stage of developments as we had a major change to make with presets.
So we had to change the name (adding the 15), or it would have crashed the plugins. This will not happen with upcoming products.
