"The Synergy is a digital additive synthesizer that uses phase modulation with 32 digital oscillators and produces a unique sound. All functions have been tested and are in great working condition. This is a vintage Digital Keyboards Synergy synthesizer. This gem is a piece of music history, with an iconic sound that can be heard in such places as the Tron soundtrack. It has been used and loved, which shows, but is a great synth!
This unit is in excellent working condition, with only one known function issue. The Eb key in the 2nd octave on the keyboard seems to stick after the first time it is struck (it is playable again 1 time after each power-up). There are no other known issues. The pictures are of the actual item."
"Time to dive deep into Cunsa's main features! In this first tutorial, we will explore how a single filter works and how to combine them together to get the signature "Cunsa sound." This should get you started with CUNSA and let you understand its basic functioning. In the next episodes, we will see more specific applications!

"For the month of April, we're very excited to have BRiES take over our channels! Known for his in-depth tutorial videos on a variety of #eurorack modules with supremely musical excerpts, as well as writing his own extensive guides to Generate 3 and Compare 2, he's always eager to share his latest insights into analogue synthesis."
