Erica Synths Pico Envelope Follower (EF) & PICO VCA2


video by Erica Synths

"Pico EF is Erica Synths take on envelope follower module in 3hp! Pico EF features a preamp with +40dB gain, envelope output with adjustable attack time and a gate output with adjustable threshold. The Pico EF can be used as a preamp, overdrive unit or for controlling VCFs with audio signal, or to use with external instruments to control your modular system in other creative and experimental applications.

Timeline:

00:00​ Patch 1 "EF to LPG offset"
Using envelope generated from the breakbeat to modulate the LPG offset and extracted gate to trigger the bass sound.

01:14​ Patch 2 "Side-chain"
Creating side-chain compressor like effect by extracting the envelope from Bassdrum and then inverting it with Pico Scale and then applying it to the VCA through which the hi-hats from the Pico Drums 2 are sent

02:04​ Patch 3 "EF to LPG offset"
Similar to the Patch 1 but in this case using the extracted gate to trigger the LPG internal decay envelope

02:27​ Patch 4 "Bass guitar opening VCA"
Bass guitar is plugged directly into the Pico EF and then extracted envelope from the audio signal is used to open the Pico VCA through which a sequenced melody from Pico Voice is sent

03:21​ Patch 5a "FM to LPG & triggers 1"
Audio signal from FM radio is used to change the LPG offset and extracted gates are used to trigger sliced breakbeat on the Sample Drum

03:52​ Patch 5b "FM to LPG & triggers 2"
Similar setup as in Patch 5a, but instead of triggering slices extracted gates are used to trigger randomly selected samples

04:32​ Patch 6 "EF as Distortion"
Using Pico EF as distortion module by adding a lot of gain to the Bassdrum module

05:10​ Patch 7 "Bass to Plasma Drive & LPG"
Using Pico EF to amplify bass guitar which is after that send into the Plasma Drive which is afterwards set through the Pico LPG which offset is modulated by the envelope generated from the bass guitars audio"



Pico EF is Erica Synths take on envelope follower module in 3hp! Pico EF features a preamp with +40dB gain (enough to boost even guitar and dynamic microphone signals for use in a modular system), envelope output with adjustable attack time and a gate output with adjustable threshold. The Pico EF can be used as a preamp, overdrive unit or for controlling VCFs with audio signal, or to use with external instruments to control your modular system in other creative and experimental applications.

The Erica Synths Pico VCA2 is a compact voltage controlled amplifier module, based on reliable AS3330 chip. It features two independent channels, and the first one comes with the manual offset adjustment, useful for full span vibrato effects. Audio and CV inputs of the first VCA are normalised to the second one, so the module can also be used as a buffered audio splitter. VCAs are DC coupled, and they can be used for controlling amplitude of control voltage signals.

RRP: 85 EUR (VAT excl.)
