Richter Anti-Oscillator Manual/Patch Ideas

Post by shady smiles »

Greetings!

As per the discussion in the big "meta" malekko manual thread, this is a breakout for Richter Anti-Oscillator manual and patch ideas. Discussions not specific to the Anti-Oscillator might best be held in the meta manual thread (but don't overthink it). I'll update this post with a pointer to an assembled doc once it's in progress, status updates, etc.

Any and all input welcome and greatly appreciated.

Cheers!

Anti-Oscillator Functions

Initial Frequency Fine Control: Provides fine tuning of the oscillator’s initial frequency. (1 octave range.)

Initial Frequency Coarse Control: Sets the coarse tuning of the oscillator’s initial frequency. (10Hz to 10kHz, 10 octaves.)

Exponential FM Input: In conjunction with the associated Exponential FM Input Attenuator, provides standard exponential frequency modulation (FM) of the oscillator. The Exponential FM Input is normalled to the Mayhem wave shaped output. Inserting a patch cable breaks the normalization.

Exponential FM Input Attenuator: Attenuates the signal found at the Exponential FM Input, allowing control of standard exponential FM functionality.

Linear FM Input: In conjunction with the associated Linear FM Input Attenuator, provides standard linear frequency modulation (FM) of the oscillator. This input is AC coupled allowing FM modulation to be introduced while minimizing unwanted pitch shift. The Linear FM Input is normalled to the Mayhem wave shaped output. Inserting a patch cable breaks the normalization.

Linear FM Input Attenuator: Attenuates the signal found at the Linear FM Input, allowing control of standard linear FM functionality.

1v/Octave Input: Bipolar input for oscillator pitch control using the 1v/Octave standard. Responds to a 10 octave range.

Initial Wave Control: Sets the initial waveshape to be modulated by the Wave Envelope. Morphs from a square wave to something altogether twisted.

Wave Envelope Input: In conjunction with the associated Wave Envelope Input attenuator, controls the modulation of the Anti-Oscillator’s wave folder. Wave Envelope input is normalled to the Tri wave output. Inserting a patch cable breaks the normalization. For sweeping wave transitions, try plugging in an LFO or envelope. Advancing the folder in a non-linear way can be used to great effect too. For example, sending in random voltages from the noisering or wogglebug or from a sequencer can produce interesting timbral arpeggios.

Wave Envelope Input Attenuator: Attenuates the signal found at the Wave Envelope Input, allowing for control of the wavefolder’s animations.

Signal LED: Shows the current "speed" of the oscillator. When running at audio rate, the LED simply twinkles as the oscillator runs. When running at a low rate (as an LFO), the LED shows the difference in cycle for each waveform type. Green represents positive excursion, while red represents negative excursion.

Triangle Wave Output: Triangle core wave output. (+/-5v.)

Mayhem Output: Wave-folded output. (+/-5v.)

To kick things off, here's an idea courtesy of slow_riot culled from the "meta thread".
slow_riot wrote:i was always curious about how to make use of the feedback of the anti oscillator that Grant mentioned that it is great for.

So after a couple of years of patching I might have figured it out.

Requires 2 of them.

Left-mayhem to output
R Mayham to output

L triangle to R lin FM
R triangle to L lin FM

More harvested wisdom from a previous thread:
microfauna wrote:Little patch:

Mult MAYHEM out. Use as audio and fed back into WAVE ENV. Interestingly it can produce gentler sounding wave shaping.
microfauna wrote:Further little patch with Boogie:

MAYHEM out to Boogie in
Boogie 24dB out to WAVE ENV EXT in
Boogie 18dB out for audio
Wiggle Resonance and Cutoff to taste

Try other combinations for new exciting sounds

Bump for added panel guide rough mix and control descriptions.

More to come... Comments/feedback welcome!

Sure thing! Glad they help. I'll definitely add 'em for the rest as I go. Can you think of anything else? Also, is it important that they be precise? For example, taking a quick peek at the Unkle, I notice that some waveshapes OUTs measure +/-5v while others are closer to +/-4v. Is that an interesting distinction?

Thanks for the kind words!

Great chart and info. Thanks for putting it together. The cv ranges are a great help, super accurate or not.

Thanks Rico! You offering? If so, I'll take you up on it! :) (Actually, scratch that, let me buy YOU a beer for helping make this whole thing happen!)

Another Patch Idea

Post by PatrickScott »

Using the MAYHEM output:
  • Set INIT WAVE to 50%
    Connect a noise source to /WAVE ENV/EXT
    Set WAVE ENV around 70%
Seems to give best results in the 200-500 Hz range.
Applying a resonant high pass filter to the noise can help fine tune the sound.
