Example Usage
The Teia OpticTone MK2 is a versatile addition to any novice's Eurorack setup, providing a practical introduction to the world of multimode filtering and amplification through its intuitive controls and rich sonic palette.
To begin, patch an oscillator of your choice into the OpticTone MK2's audio input. For this example, let’s use a simple sine wave oscillator for its smooth characteristics. Next, connect your audio output from the OpticTone to your mixer or audio interface.
Start by selecting the Lowpass mode on the filter section. This will allow you to cut off higher frequencies, resulting in a warm and rounded tone. Gradually adjust the Frequency knob while playing your oscillator, noting how the sound evolves as you sweep through various frequencies.
Now, introduce modulation to the filter to add movement to your sound. Patch a low-frequency oscillator (LFO) into the Frequency control voltage (CV) input. Experiment with different LFO shapes like sine, triangle, and square waves, adjusting the modulation intensity to affect how pronounced the filtering becomes. Notice how the filter responds dynamically, creating fluid sonic textures.
Next, engage the voltage-controlled resonance by turning the Resonance knob up. This will accentuate the cutoff frequency, adding character and depth to your sound. As you increase the resonance, listen for the sweet spot where the tone becomes harmonically rich without feeding back uncontrollably.
To explore the unique pluck sounds the OpticTone MK2 offers, send a trigger signal (around 20ms in length) to the Freq/Amp CV input while in Lowpass mode. Observe how the Vactrol reacts, producing a short, percussive pluck. You can refine this effect by adjusting the crossfade knob to blend between the VCF and VCA pathways, allowing for a smoother or sharper articulation of sound.
Switch to the Ping input to generate punchy, rhythmic percussive sounds. Feeding it a gate signal causes the filter to resonate, similar to striking a physical object. Use the Freq/Amp knob to adjust the tonal characteristics of the ping, experimenting with high and low settings to create everything from kick drum-like thuds to snapping high-frequency tones.
As you become comfortable with these initial techniques, don’t shy away from exploring the overdrive and feedback controls to add grit and complexity to your patches. Be sure to also play with the series and parallel switch for signal routing options, allowing creative combinations of filtering and amplification behaviors.
By engaging with the Teia OpticTone MK2 in this manner, you'll not only gain an understanding of vactrol-based filtering and amplification but also begin to cultivate your own sonic identity within the modular synthesizer realm.
The Teia OpticTone MK2 provides an engaging platform for creating diverse sonic textures by cleverly blending its filter and amplification capabilities. To start, patch an oscillator of your choice into the audio input of the OpticTone MK2. The module's three essential filter types—Lowpass, Bandpass, and Highpass—allow you to sculpt the sound immediately, so begin by setting the filter to Lowpass mode and adjusting the Frequency knob to find your desired tonal character.
Next, send a short trigger signal (around 20ms) to the Freq/Amp CV input. This will utilize the Vactrol’s natural decay to produce the signature pluck sound emphasized in the MK2’s design. Experiment with the crossfade knob to blend the filtered output with the unfiltered oscillator signal for added depth and complexity. You'll notice how the integration of the VCA and VCF can dramatically transform the character of your sound.
Now, enabling the Ping input can produce exciting percussive effects. Connect a gate signal from your modular sequencer or trigger source to the Ping input and adjust the Freq/Amp knob. This will generate a quick resonant response from the filter, resulting in crisp, percussive tones. Investigate the variety of sounds by switching between different filter types and tuning the filter range switch to explore the filter's response across low, mid, and high ranges.
To add even more dimension to your patches, utilize the overdrive control to introduce mild to aggressive distortion, enriching your sound palette. The feedback knob can be adjusted to engage self-oscillation, leading to wild and experimental results. Don’t forget to take advantage of the voltage control inputs for the resonance and other parameters; modulating these will provide rich evolving textures that enhance your soundscape further.

Utilizing the Teia OpticTone MK2 for sculpting intricate sonic landscapes involves a deep understanding of its nuanced features. Let’s explore a scenario that highlights the module’s exceptional capabilities.
Begin by patching an audio source into the input of the OpticTone MK2. This could be a raw oscillator signal or a more complex sound coming from another module. Set the Filter Range switch to ‘Mid’ to strike a balance before fine-tuning your sound. Engage the Lowpass filter mode to start on a smooth path. Adjust the Frequency knob to find your desired cutoff point, where the signal begins to roll off the harmonics. As you tweak this knob, notice how the filter responds warmly, characteristic of the Vactrol design.
For added depth, utilize the Voltage Controlled Resonance feature. Patch a control voltage source into the resonance CV input. This could be an LFO or an envelope generator set to a slow modulation speed. As you adjust the Resonance knob, you can push it to the brink of self-oscillation and then back off for a more subtle enhancement.
Next, incorporate percussive elements by using the Ping input. Send a short gate signal into this input, adjusting the Freq/Amp knob to see how the filter resonates. Experiment with the decay settings; a 20ms trigger will yield an immediate pluck, whereas longer triggers can create evolving percussive textures.
To explore the dynamics further, switch the VCA and VCF configuration to Parallel. This allows you to manipulate how the VCA responds to the filter's actions. For instance, you can set the VCA's amplitude to decrease as the filter closes, creating a descending tonal effect that adds complexity to the sound.
