Warning; does not play nice when more than one key is pressed at the same time (a Reaktor limitation). Also, this is a midi effect, not all DAWs readily support a Reaktor patch in a VST as a midi effect, eg. in Ableton you will need 2 instrument tracks and then set the input of the synth to the OctoDactylus track _and_ device.

This is the continuation of the old versions of OctoDactylus that used to reside in the Other > Test Area category.

How To Use OctoDactylus
OD is a Midi effect. That means it changes a stream of midi information into a different stream of midi information. Refer to your DAW manual and/or google as to how to hook up a Reaktor midi effect. Be sure that your midi keyboard is selected as midi input for the track/plugin, and that the midi output of it is router to some VSTi or other instrument.

OD makes chords and simple arpeggios easy. You will be able to have big, difficult and scale fitting chords sound out of your instrument just by the press of single white keys.

First, pick the scale you would like to use in the leftmost box. The octave, represented by the twelve squares, should immediately represent your choice.

Next, set Split (in the Octave Map box on the far right) to the octave you want to start playing regular melody.
In the same area one can also modify how the chord and single key hits are transposed in octaves.
The Oct knob functions as a final octave transpose for all outgoing keys.

In the middle we have eight "finger" boxes labeled F1 through F8. The controls in each of those are as follows, from top to bottom:
- A text display in which the resulting note name is displayed
- An on/off switch with a light next to it to find out if it's being limited by 'MaxSteps' slider
- A slider to adjust step in scale, ie in the middle, when C is pressed, the chord will consist of steps 1-3-5-7-9-11-etc in the scale - use this slider to make suspended, fourths, sixths, etc.
- A slider to adjust octave, ie to make some inversions possible
- A velocity slider - map these to 8 level sliders on your controller if they're free

Finally there are some master controls in the Delay/velocity section.
The bottom slider limits the amount of keys in the chord. Above it is a row of lights that display the outgoing velocity of the notes in the chord.
Damp scales notes' velocity according to their place in the chord, ie the further the key is from the root of the chord, the softer the key sounds when this slider is down.
Master Velocity gives the option to scale all outgoing velocity, very handy when chords of 5 or even more 'fingers' are coming out of the sounding synth too loud.
Finally, the Strum section with a big slider, a small slider and a selector. The big slider makes it possible to delay the notes of the chord into an arpeggio. The selector (radio buttons) select the range for the delay between notes, namely 25, 100, or 250 ms. The smaller slider then, called Shuffle, enables you to bring a slight 'groove' to the delay times, with every other note sounding a little late.
