Strange and Weird Synths

Sonic Charge Synplant



Synplant is a software synthesizer with a genetic approach to sound creation. Instead of creating patches the conventional way by turning dials and knobs, Synplant lets you explore a world of organic sounds by planting seeds that grow into synth patches.


Once you are ready to get your hands dirty and dig deeper into the anatomy of Synplant you will have the option to crack open your sound seeds and modify their underlying genetic code.



The purpose of this product is to move focus away from the sometimes intricate and difficult process of sound synthesis and instead let you develop sounds by simply using your ears. You will find that creating synth patches with Synplant will be as easy as listening and deciding what you like and then having the sounds evolve in the directions you desire.

Although Synplant is exceedingly easy to use, whatever you do, do not let its relative simplicity fool you. Beneath its straightforward and playful interface you will find a versatile synthesizer of the utmost quality with lots of character.


FXpansion Orca


Orca has a simple subtractive synthesis structure, being comprised of an oscillator, filter, fixed amp envelope, velocity sensitive filter envelope and an amp module. The monophonic voice engine in Orca runs at twice the hosts sample rate to reduce the aliasing caused by the non-linear analog modeling of the filter and amp modules. A voice priority of newest note is used, and every new note re-triggers the amp and filter envelopes.


Asymmetric Non-linear Analog Modeling

The key component to Orca’s incredible sound comes from not only the high quality anti-aliased unison oscillator, but the asymmetric non-linear models of circuit components. For example, the diode limiter in the resonance feedback loop of the filter contains two diodes in a limiting structure as shown below:

When each diode is manufactured there are slight differences in them which is called component mismatch. These small variations mean that circuits like the above are asymmetric, so when you run audio signals through them you get second order harmonics which are very pleasing to the ear. These harmonics are typically labelled “warm” and “rich”.

Sometimes mismatch is not a good thing, sometimes you need matched components to achieve a particular task, but other times it’s critical to obtaining a great sound. Care has been taken to accurately reproduce the main asymmetries in the signal path to give the filters and amp section in orca its great sound.
