Product Information
Full details
The Erica Synths Pico Modulator is designed for modular synth users looking for a compact and affordable way to integrate essential envelope generation and voltage-controlled amplification into their setup. Its primary benefit is combining two crucial functions into a single 3HP module, simplifying Eurorack builds and making it ideal for basic tasks like creating pitch envelopes. A potential caveat for advanced users is its straightforward control set, which may limit complex modulation possibilities.

FAQs
What does '3HP' mean?
HP stands for 'Horizontal Pitch' and is a standard unit of width in Eurorack modular systems. 3HP means the module takes up 3 standard Eurorack units of width in a case.
What is the difference between AD and ASR modes?
AD mode creates an envelope with an Attack phase and a Decay phase, which then returns to zero. ASR mode adds a Sustain phase after the Attack, holding the level until the Gate signal drops, after which the Release phase begins.
When would I use Lin vs. Log envelope shapes?
Linear (Lin) shapes provide a constant rate of change, often sounding more natural or mechanical. Logarithmic (Log) shapes provide a more exponential or curved change, which can sound more organic, punchy, or smooth depending on the curve.
Can this module be used as a standalone VCA without an envelope?
Yes, you can use it as a VCA by patching a CV source (like an LFO or another envelope) into the 'CV In' and controlling the overall gain with the 'VCA Gain' knob. The envelope generator can be bypassed or ignored in this configuration.
What is the maximum attack and decay/release time?
In normal mode, attack and decay/release times are up to 4 seconds. In loop mode, these times can be extended up to 8 seconds.
What is the output voltage range of the Envelope Generator?
The Envelope Generator outputs a voltage range from 0V to 10V.
Does this module require a separate power supply?
Yes, like all Eurorack modules, it requires a standard Eurorack power supply connected to your modular case.
Troubleshooting
No sound output
Ensure the audio signal is patched correctly to the module's input and the module's output is patched to your mixer/output. Verify that the VCA is not fully attenuated (CV in at 0V) and that the Gate input is receiving a signal.
Envelope not triggering
Check that a Gate signal is correctly patched to the 'Gate In' and that the signal level is appropriate for triggering. Ensure the module is receiving proper power.
VCA level too low or high
Adjust the 'VCA Attn' knob. Ensure any CV signal patched to the VCA's CV input is within the expected range (0-10V for full effect).
Loop mode not working
Confirm that no signal is patched to the 'Gate In' when using loop mode. Ensure the 'Attack' and 'Decay/Release' knobs are set appropriately for the desired loop duration.
Pros and Cons
Pros
- Space-saving 3HP design combining EG and VCA.
- Affordable entry point for essential modulation.
- Intuitive controls suitable for live performance.
- Flexible AD/ASR and Lin/Log shape options.
- Loop mode adds versatility for drones and rhythmic patterns.
Cons
- Limited number of parameters compared to dedicated EG or VCA modules.
- May not offer the depth of control required for highly complex modulation.
- Logarithmic envelope shape might be a simplification of true exponential curves.
- No dedicated CV inputs for Attack or Decay/Release time, only for VCA gain.
Setup, Compatibility & Care
Setup: The Erica Synths Pico Modulator is a Eurorack module and requires a standard Eurorack power supply and a case with an available 3HP slot. Connect your audio sources to the module's input and your output to a mixer or other audio processor. Use Gate signals to trigger the envelope generator.
Compatibility: This module is compatible with any Eurorack system adhering to the Eurorack power standard. It functions with standard modular audio and CV signals.
Care: To maintain optimal performance, keep the module free from dust and moisture. Clean the surface and knobs with a dry or slightly damp cloth. Avoid using harsh chemicals. Ensure connections are secure but do not overtighten.
