Behringer 921 Oscillator - Euro Trig Analog Computer
video upload by O.Z. Hall
"I just completed a Trigonometry Class (working on an EE course of study). When they got to the 'Graphing Trigonometric Functions' I realized that I could actually implement these functions with Eurorack modules acting as an Analog Computer.
I hope you enjoy this #shorts video."

Touché x Felt Instruments
"Felt Instruments develop timeless sample instruments with their own unique, magically organic character. Listen to their instruments Helenko and Bardzo come to life even more when using our Touché series of controllers to morph their texture in real-time. Thanks to Felt Instruments' native integration with Touché, the plugins will react directly to your gestures without any additional setup."
Roland Jupiter-8 | Can a synth be worth this kind of money?
video upload by Espen Kraft
"Is the Roland Jupiter-8 really worth what the market is commanding these days? In my opinion, not a chance. It's a fantastic synth, but no synth is worth those prices, musically.
Of course, any object is worth whatever anyone is willing pay. That's the whole idea behind capitalism, but again, not musically. Period.
The way it looks made it the obvious 'poster' synth to be used in all those music videos in the 80s and that has made it so desirable, the looks. That's my firm belief. If you want the Jupiter-8 sound in a hardware form without going bust, get the MKS-80.
Again, a big thanks to Joakim Tysseng for letting me enjoy it for so long. Thanks man!"

" It was completely overhauled by Switched ON Music Electronics in Texas Austin in 2017 $1,088 to fix everything. Attached photo is the cost of work and the parts they replaced. ($1,088 to fix everything) So it should be still up to date since I used it less than 3 hours since 2017. There’s some cosmetic wear and the handle is missing. The previous owner replaced the keyboard connector to a five pin sturdy din connector so it’s solid."

"Sequential Circuits Prophet 5 Rev 3.2 in collector-grade condition and in perfect working order. Recently serviced and given a clean bill of health, this Prophet is a one-owner instrument, complete with the original shipping box. Founded by Dave Smith in 1974, Sequential Circuits forever changed music technology with the advent of the Prophet 5, which broke new ground as not only the first polyphonic synthesizer to enable players to store and recall presets, but also as the first musical instrument with an embedded microprocessor."

Korg Lambda ES-50 Vintage Polyphonic Analog Synthesizer SN 234417

, also on Reverb
"The Korg Lambda is a fully polyphonic 48-key preset synthesizer, and this example is very well-kept and thoroughly tested.
The Lambda ES-50 features two banks of sounds. Percussive (Electric Piano, Clavi, Piano, Harmonics) and Ensemble (Brass, Organ, Choir, Strings I, Strings II). These presets are all available simultaneously, ideal for thick layering, and each key is articulated independently (ensuring none of the "note stealing" pervasive in synths with fewer voices).The Percussive sounds have a fast attack and variable decay envelope, and the Ensemble sounds have both preset and variable attack/release envelopes.
The Lambda uses divide-down technology with three oscillators that are mixed and filtered using fixed circuits to create the preset sounds. The control panel boasts controls for basic low-pass filtering of the Percussive and Ensemble tones, and each bank of sounds has its own dedicated Volume slider and Tone knob. There is also a control for "click" (used to add attack to the EP sound) and a filter cut-off control for the Brass sound, which has its own paraphonic filter - tuned to give a slightly resonant peak to the sound, and with its own preset filter envelope.
An Octave switch puts the keyboard in regular or Octave Down mode. The three oscillators can be detuned to thicken the sound further, and analog chorus can be independently applied to the Percussive and Ensemble sections. The joystick acts as a pitch bend control, doubling as a sweep control for the chorus. Vibrato can be switched off the Ensemble sounds, and Percussive sounds feature a variable Tremolo and a Sustain switch that turns Decay into a Release."

Korg Mono/Poly MP-4 Vintage Analog Synthesizer Keyboard SN 372444

"This Mono/Poly has been thoroughly tested, and all functions work as intended. The Mono/Poly is a 44 key "mono-polyphonic" analog synthesizer manufactured by Korg from 1981 to 1984. This model is the sister synthesizer to the Korg Polysix, with four highly stable voltage-controlled oscillators (VCOs), a 4-pole, self-oscillating low pass filter (LPF), several modulation capabilities and pseudo-polyphony (paraphony) functionality.
The four VCO's can be shared in four-voice Polyphonic mode, or linked in Unison for a versatile monophonic lead. Each VCO has its own level, tune, and waveform type control. Waveforms include triangle, sawtooth, and variable pulse wave. It has a great VCF (filter) section as well as two envelope generators (one for the oscillators and one for the filter), and there are also two individual LFO's which can be used to modulate the Pulse Width, Envelope and Arpeggiator independently.
A very flexible and fun synthesizer, other cool tricks up Mono/Poly's sleeve include chord memory and an effects mode in which oscillators have a variety of ways to be synced. The built-in arpeggiator and sequencer can run all 4 VCO's at a time or cycle through each voice per note. There's also portamento, CV/Gate, VCF and VCO mod inputs, a white noise generator, and the pitch/mod wheels can be assigned to control LFO, pitch, or the filter."
