KrOn

KrOn is a DSP and CV modulator & sequencer allowing to control Scope Synths, Eurorack Modules and Hardware Synths that include  CV inputs. It is compatible with V/Oct, and includes two modes for the Korg MS20 family (absolute and relative Hz/V). 

To work with CV hardware, KrOn requires an Expert Sleeper ADAT to CV interface. Other interface may work or not depending on their calibration. KrOn is also directly compatible with the MS20 signal follower without the need for a Adat-to-CV converter.

KrOn also includes Midi to CV conversion functions, saving the need for a Midi to CV converter. KrOn can convert Midi Notes, Aftertouch, Control Changes, Key Follow, and even includes a dedicated vibrato controller.

KrOn comes with some great Scope Synths to get you started immediately. KrOn “Max Pack” includes extra synthesizers with advanced features that can also be purchased seperately (check the shop product “Upgrade KrOn to KrOn Max Pack” as well as videos/audio below). 

Quick Examples

A few videos showing KrOn in action with hardware synths. Please forgive the videos made during the building of KrOn. Refer to the soundcloud examples for a better quality.

KrOn+MS20+Minitaur. It is easy to control V/Oct and Hz/V with a single KrOn.  The MS20 has pitch and trigger controls, while the Minimax uses pitch and 2 envelopes with a delayed start, that modulate the filter and volumes to simulate someone playing several notes.

KrOn comes with a Midi to CV extension allowing to convert any Midi keyboard into a CV keyboard. Here, it plays an Erika Synth Pico VCO that goes into the MS20 Filter. It is fast and accurate, and is available as freeware for all (see below for download link).

KrOn is great for Scope DSP Synths. Here with the FMZ “multi-synth”, ie 3 independant synths into the same device. KrOn+FMZ transorm your Scope into a multitimbral analog workstation. 

DSP Synths included with KrOn

If you do not own Eurack or Hardware analog synth to use CV, no worries: KrOn comes with a few synths, and is also compatible with the Sonic Core Modular Synth II, III, and IV.  KrOn synths can be used as standalone or with KrOn. Their singularity is their minimal use of included modulators. They all include VCA and Filter Enveloppes and they rely on KrOn for LFOs, step sequencers, extra Enveloppes, Key Follower, Aftertouch, and many other modulators. This system allows synths to share common modulators and to run along hardware synths and Eurorack modules, in perfect sync.

Volcano

its simplicity makes it the fatest and most analog sound of the whole collection. Can be modulated by KrOn, by audio signals, By Scope Modular, or by hardware modulators from your Euroracks modules or hardware synths.

JunZ

JunZ brings Volacano a step further by adding “Juno-style” oscillators and filters, a filtered noise generator and a sub with selectable shape.

Mini FMZ

MiniFMZ is a single FM Operator from the unique FMZ multisynth. All sections can be CV controlled.  The video shows it played standalone.

More free Devices

These devices are great extensions to KrOn and are available as freeware or as additions

K16 is a Blackbox III Modulator that is free for all KrOn and KrOn Max Pack users. 

Logiquencer was made to trigger the Korg MS20 through its signal follower (no need for Audio to CV converter). It can also provide triggers for Scope Synths.

Modular Patch with oscillators and filters modelled after Sequenctial Circuits vintage synths.

Convert Midi notes and Pitch Bend to CV. Supports legato Portamento.

It is included with KrOn and KrOn Max PAck, and you can also download it for free from PlanetZ Scope forums

 

KrOn Max Pack

The following synths are part of the “KrOn Max Pack” and can also be purchased on their own.

FMZ

FMZ includes 3 FM Operators and can be used to create multitimbral sequences that will bring Scope into the territories of the best workstations. 

Advanced functions are such as the different pitch bend and portamento “per operator”, the VCA triggers and amp modulation, as well as the mono and stereo insert slots and 3 stereo outputs in addition to the main outputs

Magma

Magma is all about its parallel multimode stereo filters and special selection of oscillators that can give either soft or growling sounds. It includes two extra LFOs and 2 modulation adders to mix internal modulators and CV inputs together.

Check the video showing Magma and JunZ for a demo that is worth a million words.

Spirit

Spirit comes free with FMZ .  It contains an FM Operator and a VA oscillator feeding ring modulators and a set of filters with Lowpass and formant capabilities.

It also includes 21 CV inputs to control filters and Amp of almost every section of the synth. Spirit is great to create 5-tracks sequences of FM, Ring and noise tones.
