"This monstrous synth is in great shape and sounds fantastic. There are eight analog voices which can be panned individually for some really interesting stereo sounds. The keyboard can be split or doubled and there are two oscillators per voice. It is a very warm sounding synth great for massive chords, basses and leads. This model has MIDI in out and thru.

It is quite a beast, with all the great 80s vibe and that classic Oberheim sound. In fantastic working and cometic condition overall. Fully serviced along with new wood sides. Serial No. C30418"

"The Sequential Multitrak (released in 1985) is a six-voice analog synthesizer notable for combining true analog sound with early digital control.

Each voice has a CEM3394 synth-on-a-chip, offering a single oscillator, sub-oscillator, noise source, and resonant low-pass filter. It was one of the first affordable synths to feature a built-in sequencer and MIDI implementation, making it popular for both studio and live use.

The Multitrak’s panel and parameter editing system allowed deep sound design, though programming could be a bit tedious. Its warm, punchy tone and distinctive Sequential character make it a cult favorite among vintage synth enthusiasts today.

This one works like a charm and has that analog warmth you've been looking for in a polysynth."

"Today I'm introducing the Waldorf Protein.
Based on the original Waldorf Microwave 1’s ASIC oscillator, the Waldorf Protein is an affordable, compact 8-voice polyphonic wavetable synthesizer equipped with the latest features—including advanced arpeggiators, a step sequencer, chord mode, and effects—that incorporate technology from the Iridium.
While returning to the roots of Waldorf’s early instrument design, it evolves that philosophy into a form suited for the modern era.
Measuring 252 × 170 × 48 mm (including knobs) and weighing 0.9 kg, its portable, compact chassis houses performance that exceeds its class.
The Protein makes a strong statement as the first release in an upcoming new product line.

via Perfect Circuit

The Arplus module from Zlosynth Instruments is a robust Karplus-Strong 6-voice resonator that gives you a bevy of musical scales at your fingertips. The Arplus works by selecting a particular chord based on the scale you select, stepping through the notes of that chord via the Trigger input and button. Use the Tone control to set the root note, and use the Chord control to select the particular chord. Both controls have corresponding CV inputs that let you create intricate sequences or melodic randomness. Choose from 31 different types of scales that include Western, Arabic, Indian, Japanese, and even quarter tones.

Internally, a burst of noise gets generated to create the sound, however, if you want more control over your noise bursts, an external input is available for you to patch in whatever you'd like. Use the String control to adjust how many virtual strings remain resonant after the trigger—up to 6 strings can resonate at a time allowing for soaring expanses of ambience and gorgeous clusters of notes. Sculpt the sound right on the module with a built-in filter, including resonance and cutoff, along with a Contour control that moves from short percussive bursts to long swells of washed texture.

Of course, no resonator would be complete without a stereo output, and the Arplus doesn't disappoint. Choose from three different stereo spreads: Ping Pong, which alternates voices between left and right, Root, which sends the Root to the Left and everything else to the Right, and Haas, which creates a stereo spread using the psychoacoustic Haas effect. The Arplus from Zlosynth is more than just your typical resonator, with an easy-to-read scale selector and a lovely sound that's sure to win over your heart and ears.

External audio input for custom excitation sources
