Reaktor 6


Quick Start:
After opening SY66, please begin in the B view, Live page.

SY66 utilizes 8 live, or macro knobs that can be Unipolar(0-1) or Bipolar(-1-+1). These are virtual controls that can be assigned to nearly any parameter in the synthesizer and effects. To start out it is recommended that you connect a hardware controller with 8 knobs. In the B view LIVE page you will see 8 knobs. Midi learn or assign these 8 knobs to your hardware controller, then save SY66. As you load snapshots, your hardware knobs will now change function depending on how the snapshot was designed. The assigned functions are documented above the knobs and are intended for quick variations, performance and sound design. Additionally, most snapshots include assignments for the modwheel for instant tweaking.

Instrument designed, built and documented by Jonathan Adams Leonard and including work by Martijn Zwartjes, Stephan Schmitt, Max Zagler, and Eric Wiegand.

I am surprised, the best SY 66 ever, and the microtuning option is the icing on the cake.

1.58 adds a new FM operator type Sine 2 which sounds slightly different and cool.

Updating to version 1.57 to fix a bug in 1.56 that broke some presets and add the randomization options to the master microtonal scale.

Hi Greg, first go to B view, then the Audio page and enable the Ext. In. Next you can enable the audio trigger and set a destination, the envelope follower or pitch tracker. To use as a modulation source for FM, go back to the A view and in the last (7th) column of the FM Feedback Matrix you can set amounts for the external signal as a modulator.

This is getting really great. Can you describe how to use audio in as a modulation source. I read through the section in the manual but was not able to get it to work. Thank you!
