Polyrhythmic FM Drum Machine
NOTE: The initial preset is SILENT because it tends to make a sound when you load it. To start, choose a snapshot and press play on the Reaktor sequencer!
This is version 2.0 of my Polyrhythmical Quadphonical FM Modulor and is part of a series of FM feedback synths. Theres the two oscillator version (FM Modular - https://www.native-instruments.com/en/reaktor-community/reaktor-user-library/entry/show/8049/), the three oscillator version (Triphonic FM Modulor - https://www.native-instruments.com/en/reaktor-community/reaktor-user-library/entry/show/11229/), and now this is the four oscillator version.
This ensemble is composed of four drums that use FM synthesis and cross modulate each other (which can be defined by the FM Matrix in the center). Its nice because each sound becomes somewhat dependent on other sounds :)
Each drum has controls for Pitch, Envelope, Filter, FM LFO amount, and Pitch Modulator Env.
The Sequencer does not work in the traditional sense. Its done by making each drum have a different speed based on different subdivisions of a measure. So one synth could be going at 1/32 repeating, the other at 3/24, and so on.
The sequencer is an XY grid:
- X axis controls the type of subdivision (2, 3, 4, 6, 12, 16, 24, 32)
- Y axis controls how many of those subdivisions (1, 2, 3, 5)
So, when Y = 2 and X = 12, its two 12th notes repeating. Y = 3 and X = 32, its three 32nd notes repeating. Its great for developing nice polyrhythms.
You'll notice that each drum actually has two sequencers. You can just have it use the central sequencers, or you can have it sequence between two different sequencer subdivisions. Turn that on and off through the Seq Type button.
Each oscillator is being panned with an envelope of one of the other oscillators, so its very stereo. In the Mixer/FX area you can change the width of the stereo field of each drum.
