The first-generation Syntrx from Latvian synthesis maestros Erica Synths was a fantastic "reimagining" of the 1972 EMS Synthi AKS. The original Syntrx was a highly desirable analog synth with a limited production run of 1056 units (and a premium price tag of $3029 USD). Erica is back with the second-generation Syntrx II, building on the foundation of that 3-oscillator, mod matrix-centered design and adding new features while reducing the cost by more than $1000.

The Syntrx II is like a whimsical time machine that transports us to an earlier golden era of electronic music, all while winking mischievously at the modern world. With its retro aesthetics and a sound design palette that is seemingly bottomless, this synth is a fascinating synthesis of nostalgia and innovation.

Much like the Synthi AKS (and Syntrx I), the design of the Syntrx II is both practical and alluring. Its all-black faceplate, analog VU meter, wooden panels, and vintage-inspired knobs exude a warmly inviting aura as if trying to lure us into a retro-futuristic wonderland.

Despite its obvious charms, this isn't necessarily the first synthesizer the average musician or producer would want to jump into. It's a lovely, musical ocean of a synth, but the water can get quite deep, and it seems to encourage wild experimentation. From my perspective, this is very much a good thing! This beast can produce a wide range of tones, from hauntingly ethereal melodies to earth-shaking basslines that would rattle neighbors in the next county. The architecture of the signal path, and notably the digitally controlled 16 x 16 point analog patch matrix at its heart, all seem to reward experimentation and sonic exploration. It took 10 minutes out of the box before I was (deliberately, ecstatically) lost in some deep-sea Morton Subotnick-esque [Tape Op #155] trench.

The stereo speakers from the first-gen Syntrx have been removed to make way for new modules and functionality, including a new envelope follower on the first of two input modules. The envelope follower allows for sidechain-style interactions with the looping trapezoid envelope generator sections, VCA, and other utilities. It can now also record up to eight seconds of your physical movements using the X/Y joystick, effectively turning this into another repeatable modulation source. A new sequencer function conveniently (and cleverly) uses the matrix and allows for editing of recorded modulation – a friendly solution for immediate melody creation. A new input channel on the matrix for Oscillator Shape allows for great PWM-style [pulse width modulation] tones and plenty of additional patching ideas. The filter palette has been expanded with a selectable high-pass and band-pass option in addition to the original low-pass, and it's still capable of the same sweet and/or nasty degrees as the original Syntrx. The digital effects section sounds great and offers either reverb or bucket-brigade-style delay. Both can be tweaked further in the settings menu: the delay is switchable to a "tape style" mode, and the reverb can activate a feedback circuit that enables infinite sustain. The second input now features an inverter, which can be handy to help flip the phase on an input source for processing.

Every great piece of gear has its idiosyncrasies, and the Syntrx II is no exception. Like a cheeky robot determined to break free from its programming, the Syntrx II has a mind of its own. Don't be surprised if it starts producing unexpected sounds or glitches. It's all part of the Syntrx II's mischievous personality; unpredictability as a feature.

The patching matrix, while intuitive once you get the hang of it, can be a bit like solving a Rubik's Cube in the beginning. But once you've cracked the code, you'll feel like a synth wizard, manipulating sound (and even full stereo mixes through the dual inputs) while cackling like a mad scientist.

In conclusion, the Erica Synths Syntrx II is a whimsical marvel that offers a delightful blend of retro charm and state-of-the-art sound. Its vintage aesthetics, coupled with its captivating sonic capabilities, make it a synth lover's dream. Just be prepared for its playful quirks and the occasional journey through the sonic time machine. The Syntrx II is not for the faint of heart, but is a worthy companion for those seeking adventure in their musical endeavors. So, put on your fanciest Roxy Music-era Brian Eno [Tape Op #85] cosplay, fire up the Syntrx II, and let the synth-induced euphoria take you on a journey to the past and future all at once.
