"The ARP Odyssey was an analog synthesizer originally produced in 1972 by the American manufacturer ARP Instruments, Inc. that quickly garnered a faithful following among musicians. Well respected for its high value, ease to play and portability, the ARP Odyssey had undergone several improvements during its history and continued to be a long-seller until manufacturing stopped in 1981 due to economic hardships and the digital surge. Loved by a wide range of musicians as a historical classic, its sound can be heard on numerous classic songs.
Now, KORG has brought back the ARP Odyssey for today. With the advisory assistance of David Friend, the co-founder of ARP Instruments, KORG has completely reproduced the original circuitry for artists looking to recreate classic sounds and explore new ones. Together the engineers at KORG and Arp were able to nail the sound and feel of the original. Every detail has been carefully considered to stay true to the quality of the original, down to the sophisticated semi-hard case.
The legendary ARP sound is loved to this day. Long stopped, the wheels of history have again begun to move."

"Ah the 80s... the era when synth manufacturers decided we only need one knob. Despite the lack of immediate control over parameters (unless you had the PG-300 or some other modern 3rd party controller) the Alpha Juno series are great sounding synth and often get over looked due to their interface. Single DCO (Digitally Controlled analog Oscillator) with a sub-oscillator and noise through an analog lowpass filter with non-resonant highpass filter, ADSR envelope with chorus.
Tested in great working condition, just showing average cosmetic wear. Includes 2-prong AC power cable."

"Fully functional Korg Delta, fun and easy to use synth that nails many classic sounds. Tested in great working condition with just some cosmetic issues due to age!
Korg's Delta is an analog semi-poly synth/string machine, basically a slimmed down version of the Korg. Though limited in the range of sounds compared with other synths of the same genre, the sheer quality of the sound from this little beastie really does make it something of a marvel. Amazing retro synth strings and fat bass synth tones.
The synth is split into two sections, Strings and Synth, for which there are separate audio outputs along with a combined output for headphones or mixing. Each section has its own controls. The String section has two pitch sliders (16' and 8') along with two tone controls (Bass and Treble) and variable Attack and Release controls to modify the sound. The Synth section has four pitch sliders (16', 8', 4' and 2'). There is also a white noise generator along with a very effective 24dB/oct low pass filter (high pass and band pass options are included too) and full ADSR controls. The synth has no memory storage or MIDI, however it does has voltage control and gate ins and outs.
The string sounds are very basic but with its separate outputs and when mixed together with the polysynth you do get that classic 'layered' sound which is useful enough on this synth; and it's fully polyphonic, so you wont be running out of notes! There is a handy joystick to the left of the 49-note keyboard for pitch bending and modulation capabilities. The construction is solid and heavy partly due to the implementation of a wooden base but also because it was designed for heavy usage on the road. Added bonuses: noise modulation, stereo out (strings/synth split), and the ability to combine synth and strings or turn off oscillators in the mixer section."

"A 16-voice analog modeling synth that also features wavetable oscillators. It's characterized by its thick sound from 3 oscillators and a filter with a strong, distinctive character. It comes equipped with 3 LFOs, 4 ENVs, 2 multi-mode filters, extensive modulation options, a step sequencer, an arpeggiator, and more.
〇 Condition
Tested and confirmed to work without problems.
The system version has been updated to Ver 3.02.
Preset data have been reset to factory default.
The keys are slightly yellowed and have uneven coloring. There are scratches on the side panel. There are also other small scratches in various places.
Please check the photos for details."

Roland Jupiter-6 61-Key Polyphonic Analog Synthesizer with Owners Manual SN 322266

"Introduced in 1983 as a more affordable counterpart to the legendary Jupiter-8, the Roland Jupiter-6 quickly established itself as a classic in its own right. With six-voice polyphony, dual oscillators per voice (12 total), and early MIDI implementation, the Jupiter-6 combined analog warmth with forward-thinking control. Its oscillator stability, versatile filter section, and hands-on interface make it a highly sought-after instrument for both vintage collectors and modern producers.
The Jupiter-6 delivers the unmistakable Roland analog sound—lush pads, powerful leads, sweeping drones, and edgy textures—thanks to its rich filters, dual LFOs, and intuitive front-panel programming. Known for its reliability and build quality, this synth remains one of the most respected analog powerhouses of its era."

Dual precision Vco into 12db multi Vcf in low pass mode to create a fat drone pad patch
video upload by Radical Frequencies Modular
"The dpvco sends 2 detuned saw waves into RF transistor mixer and then into 12db multi Vcf in LP mode. I use 2 of the new RF ADSR envelopes in slow mode one for RF Vca one for filter.
Dpvco beta is modulated linear by lucky voltages and exponentially from alpha Vco ."
