This Is Not Rocket Science Wobbler 2 Eurorack LFO & Drum Synth Module

WOBBLER²

Wobbler² is an advanced LFO & a drum synthesizer. This is our original Wobbler with an upgrade!

The Wobbler² still is the LFO that adds controlled chaos to your sound and has five shapes, two of which are based on physical modelling. These five shapes now have five corresponding regions of drum.
This upgrade of our Wobbler is entirely made possible by Raspberry Pi. Their RP2040 is a powerful little monster that gave us the compute to bang on. Twang and Double Pendulum already had a percussive element and a decay story to it. The jump to add a drum synth felt logical. Besides, you always need more drums.

Wobbler² still gives you direct visual feedback of your CV output.
You can see the LFO wobble and the drum hit.

ADVANCED LFO MODE
A classical music instrument always contains some natural chaos giving depth to its’ sound. In synthesized sound usually you have to make a choice between being in complete control of a flat sound or allowing randomness to run wild and give it character. We have used fresh takes on classical LFO generation and physical modelling as a modulation source so that Wobbler² can give you the best of both worlds – naturally occurring chaos that you can control.

• With the SHAPE knob you select between five shapes
• Basic LFO
• Self-phased LFO
• Twang
• Double pendulum
• Sample-and-hold
• The MOD knob controls shape specific modulation
• The big FREQUENCY knob changes the speed at which it oscillates
• The SYNC input will change the FREQUENCY knob into a sub-divider of the incoming tempo
• The PHASE knob controls the phase difference between the two outputs
• SHAPE, FREQUENCY, PHASE and MOD all have CV inputs
• The TRIGGER button can reset the phase of the LFO or restart the algorithm depending on your SHAPE selection
• Both outputs have a knob to alter or invert the amplitude of the signal
• Both outputs also have their own trigger output – sending a trigger at the start of each new phase
• The two LED arrays show you the generated CV levels of each output

DRUM SYNTHESIZER MODE
With the push of the BANG ON! button you shift the Wobbler² into drumming mode. Giving you a range of drum sounds, with five regions of recognizable drums and a lot to explore in between. There are multiple percussive sets with real and imaginary drums to bang on. Along with the drum Wobbler² provides the envelope or the negated envelope (ducking) and adds flexibility on the decay of both envelopes. Play with it, see how you feel.

• With the REGIONS OF DRUM knob you select a region of 5 drum styles
• Big drum
• Block
• Sproing
• Snare drum
• Hi-hat
• The LENGTH parameter controls the sound or the silence
• The ALTER parameter controls modulation, which means something else for every drum synthesizer
• The big FREQUENCY knob changes the pitch
• The ACCENT input adds an accent
• SHAPE, FREQUENCY, PHASE and MOD all have CV inputs
• The TRIGGER button bangs the drum
• DRUM output parameter ranges between distortion or compression of your drum sound
• ENVELOPE output parameter ranges between the normal and negated envelope of your drum sound
• Both outputs also have their own trigger output
• One LED arm will show you when the drum hits and the other LED arm shows you the associated envelope moving
