Behringer Pro-800 in detail:
The Pro-800 is a clone of the popular 1982 retro classic Sequential Circuits Prophet-600. In favour of the compact, rack-mountable case, Behringer omits the opulent case along with the 61 keyboard keys in the reissue, making the instrument pleasantly portable. Two voices have been added to the reissue, giving the Pro-800 a total of eight voices. In addition, the synthesizer now features a noise generator and more memory slots. Since the release of the Prophet-600, there have been several additions and improvements, most of which did not come from Sequential itself. The most famous enhancement might be the GliGli upgrade, which is almost fully applied to the Pro-800 as well and does much more than implement MIDI CCs, velocity, Aftertouch and more waveforms for the LFO. In short: the Pro-800 is the compact and above all enormously expanded version of what the Prophet-600 only became much later. The smooth basic sound of the original can also be attested to the Pro-800.
The synthesizer
The two assertive oscillators, each based on a CEM3340 chip, each have sawtooth, triangle and square waveforms and pulse width controls. Oscillator A can be synchronized to oscillator B. Both VCOs are combined in the mixer, here you also find the noise generator. The nice basic sound is processed with a characterful 24dB Lowpass filter, which is also known as Curtis VCF. It behaves similarly to a Moog filter but sounds different from the transistor cascade due to the IC CEM3320 used. The lower half of the knob deals with the modulation section.
Poly-Mod is composed of the sources Filter Envelope and Oscillator B and is applicable to the frequency of Oscillator A and the Cutoff. This is also where the somewhat harder sounds for the oscillator and filter FM are created.
The LFO provides a total of six waveforms of two sets each and is finally dosed via the modulation wheel of a connected MIDI keyboard. The frequency and pulse width of the oscillators A and B as well as Cutoff are available (simultaneously) as targets.
The two ADSR envelopes are permanently assigned to filter and VCA. Thanks to a total of 400 memory locations, no sound idea is lost anymore.

Sequencer & Arpeggiator
The ingeniously simple sequencer gives access to two patterns, each of which can be up to 400(!) steps long; rests can also be programmed. The notes for this are played via a connected MIDI keyboard. After input, the patterns can be transposed with the keyboard. The arpeggiator primarily offers the playback modes Up, Down, Up & Down, Assign and Random. Synchronization to other equipment is done via the analogue clock input or MIDI/USB.

I’ve always wanted to own this synth but the original was just not affordable for me. The version by behringer is an impressive synthesizer with eight-voice polyphony. Its analog sound exploration possibilities are astounding, and it's incredibly inspiring. What's mind-boggling is that Behringer manages to offer all this at an affordable price. It's a synth that invites creativity and defies expectations! 🎹🔊
Easy to handle, big sound, robust, elegant and for a very ridiculous amount of €. Not to mention the presets capability. The only negative point would be these damn menus, and poorness of the behringer app.
