Kontakt multi-channel sequencer experiment

Common question about Cracklefield instrument is: Can I use it as a sequencer to play other instruments? It's tempting idea, Kontakt does output MIDI generated by loaded instruments, but the problem is, all messages are put on a single channel. As a workaround Cracklefield has MIDI recorder, so you can export it's output by MIDI clip drag'n'drop, but the clip has to be recorded beforehand and it's not quite as fun as live output.
I have been pondering this and came with somewhat convoluted solution, worthy of fairly confusing name. Kontakt has multiscript feature, you can run scripts on MIDI level before MIDI data is passed to individual patches. You can change MIDI channel for events with multiscript. So my idea was to prepare sequence data at sequencer instrument level, in a way which would include channel/cursor number. Send it to another instance of Kontakt, where it would be decoded to multichannel sequence on multiscript level. Lets' see how it works...


Maybe it's not very practical, but isn't that fun? You can make it work with Cracklefield 1.2 or Orchestra Enigmatica, both of which generate a kind of multi-channel sequence and include a function which prepares data for receiver/decoder multiscript. They convert notes to series of CC messages, which include note number, velocity and channel/sequence number and can be then interpreted by receiver multiscript.

If you'd like to try it, download the receiver multiscript here.

Mind you, this is experimental setup, not guaranteed to work for you. Also you may need a bit of advanced know-how with Kontakt and DAW configuration, for example, know how to connect one instance MIDI out to another instance MIDI in. Read included text file for more information. Have fun.

Cracklefield update 1.2

I updated Cracklefield to 1.2, introducing introducing field animator, new function which can dynamically transform the whole sequencer field. The field can be scrolled, rotated or evolved using game of life family of cellular automata. Different transformation modes can be sequenced or combined for some extra generative fun.

Cracklefield

I have released new music machine at Kontakt Hub, it's named Cracklefield. This idea has been following me for a long time. I imagined a grid based sequencer, with objects traveling in different directions, bouncing off walls and colliding with each other, creating dynamically evolving patterns. Cracklefield is such generative music machine, experimental sequencer, more a simulation, than a loop player.


The sequencer workspace, the field, is cellular grid. The field can be read or modified by cursors, pointing at sequence track playing position. The cursors can travel the filed in any direction, horizontally, vertically or diagonally, each at it's own rate. They can bounce off field edges or obstacles (walls) and, what is the fun part, bounce off each other. Just imagine several sequencer tracks playing 'pong' with each other. On next level, cursors can interact with the field; paint, erase or flip cells, build or destroy walls, shift whole field rows or columns. It's a playground for building evolving patterns - set initial conditions and see what would it sound like.
Cracklefield can also use cellular automaton named 'Langton's ant'. An ant is basically a cursor, which changes direction depending on what kind of cell it steps on. For example, it turns right on a filled cell and turns left on an empty cell, flipping the state of cell it has visited. Sounds very simple, yet it creates surprisingly complex structures. In Cracklefield you can combine several ants of different types to explore variety of possible generative pattern setups. The machine is using a note map, assigning each cell a note number, according to one of different algorithms, to play melodies, or create round robin percussive patterns.
Cracklefield can also act as an apreggiator. Each cursor can be bound to one of notes from the chord being currently held. Arp patterns can modulated (transposed depending on cursor position) and fit to a scale pattern, while each cursor can play a different sound.

Here's a video showing some of the possibilities:

 
This machine is not really about the sounds, but it has been built on a sample player, so obviously it needs samples. I wasn't quite sure how to approach this and in the end I decided to pick a set of sounds that, most likely, nobody would have already, as it's not a kind of instrument, one would be interested in just to get more pianos. The Cracklefield sample set is mostly based on acoustic/electroacoustic instruments, or found sounds, unconventional, experimental or unusual sounds, featuring a hollow soviet balalaika, copper rod mallets made with contact microphones, experimental guitar setups, glass chimes or wire-brushed crash cymbals. On the other hand, the machine is designed, to make adding new sounds relatively easy; just duplicate a group, put new samples and refresh the instrument. There's also a built-in note recorder, it allows the user to capture multichannel MIDI clips, which then can be exported to a DAW by drag'n'drop mechanism and reused elsewhere.

Here's another video, playing with random electronic drum samples, shows how it looks and sounds to use the instrument:


It is thus far the largest, most complicated and one of the most unusual projects I put myself into. If you'd like to learn more about Cracklefield functionality, see the manual:

Or watch even more videos:





Cracklefield needs full version of Kontakt 5.6.6 or newer to run. It takes 950MB of hard drive space after unpacking (the samples are in plain wav format). You will need at least 1280x1024 screen resolution to be able to see the whole interface without scrolling, it's bigger than standard ones, as there are plenty of controllers.

Now updated to 1.2 - with field animator...

Rhythm Assembler

And now something completely different... A step sequencer.

Well, it really is a bit different. Rhythm Assembler is a drum computer script I wrote for Kontakt, remains of a cancelled project. Usually a step sequencer has a regular grid, you can use to place notes. Here, you define the grid structure, assuming there's a note at every step. It may seem backwards, but once you overcome old habits, it may be simpler to do it this way. Example, you want a four on the floor, you only need to program one step. Also, I feel, breaking down a rhythm to such formula, gives me a better understanding, of how the rhythm works.

The machine offers 8 sequence tracks, each can have a different grid sequence with different cycle loop. Grid step is defined as a multiplication or fraction of base duration, like "1 quarter note", "3 sixteenth notes", "1/3 half note" or "3/4 whole note". On top of that you can program a repeat sequence, telling the machine how many times to repeat a grid step. Considering both sequences can have a different loop cycle, it is possible to program fairly complex rhythms with a simple formula. Also the sequencer is not bound to a time signature, you can program odd, irregular rhythms, rhythms with asymmetric measures.
Another, somewhat uncommon feature of the sequencer is the "humanizer" function, which not only can delay notes by random duration, but can play them too early as well. This "timing error" function can be configured separately for each track.

And here's a quick overview video:

Rhythm Assembler is just a script, it comes with no samples and no instrument patches. There are script preset files, you can add to an existing instrument. Which is also the reason, there is no custom graphic interface and the background is black (for the workaround to disable instrument's background image). The script requires Kontakt 5.6.5 or later to work. It could be rather easily ported to any earlier version of Kontakt 5 and with some work and (loosing option to rename sounds) to Kontakt 4.

The script is free to download and use (although it's not free to re-distribute). DOWNLOAD IT HERE. To install the script, you need to locate Kontakt's user preset/scripts folder and copy the "Rhythm Assembler" directory there. There are several example presets, with pre-programmed rhythms and an "empty" preset.

There's some further beta development, you can follow here (scroll down the thread).
