Behringer POLY D Analog 4 - Voice Polyphonic Synthesizer with 37 Full-Size Keys, 4 VCOs, Classic Ladder Filter, LFO, BBD Stereo Chorus, Distortion, 32 - Step Sequencer and Arpeggiator

I bought this as I wanted a fairly simple synth with large, quick access controls. I had been considering a (Behringer) model D for a while, but liked the idea of being able to use the oscillators individually (paraphonicly) - something I really missed being able to do with the SE-02. So far it has lived up to its hype. Sounds really good (I presume the addition of polyphony hasn't harmed the model D sound!). Yes, its not truly polyphonic (only single filter/adsr etc) unlike the Deepmind with its individual voices, but if you think of it as a monosynth-plus - all the richness with added the added benefit of being able to do simple pads and chords. The simplicity of the layout and huge controls makes this a great learning/starter tool for a beginner in subtractive syntheses (like me!), with absolutely no menu diving or hidden settings.There is a limit to the sounds you can produce, but with the options of using both the LFO and the 4th Oscillator as a modulation source you can still have alot of fun). The chorus modes also adds to the overall final sounds. If you are truly after a polyphonic synth then this might not be the right choice, but for anyone wanting the 'mini moog' sound without the technical issues associated with owning a 45yr old synthesiser or the huge costs of the later Model D, the Poly D has so much to offer.In my opinion there isn't any other analogue keyboard that (in this price range) that can do the same. If Behringer has just stuck their model D onto a keyboard it would have not had the same success and at only 35% more than the original price of their Model D, if you have the space, the Poly D is a great buy.Cons:?I have not had it long enough yet to find any big issues. I am not a massive fan of Behringer's Sequencers and this is the same sequencer that is on the MS1, Crave and ODESSEY. It works, but I don't find it that intuitive and its a shame it is limited by its 32 steps. However, if you own more than one of the Behringer range at least you only need to learn its functions once :)

Brilliant sounds. Lots of reviews and great tutorial from the likes of sweetwater.comNOTE: you must be prepared to update the firmware as soon as you get it. Perhaps due to a part alteration. Keyboard will not function in the correct way out of the box, actually cuts out when playing a sustained cord while simultaneously playing other notes. Do not worry though, Firmware update resolves all issues so long as you have access to a PC or MAC with a USB A - B (printer) cable your sorted in less than 5 minutes, You-tube tutorial for the job is available too.

The sawtooth and triangle wave on each oscillator was faulty. On sawtooth the gain/level was severely reduced on all oscillators compared to other wave settings. On triangle the same was evident for oscillators 1,2 & 3 compared to that of 4. The next problem was that the C3 key stuck down and returned to original position very slowly compared to all other keys. Finally out of the box the power cable retention clip was snapped off and laying under the main panel.I’ve always wanted the mini moog but it’s too expensive. The Behringer poly D seems a perfect option, but not if it doesn’t successfully operate correctly. This has put me off Behringer products particularly as I’ve heard other peoples potential gain/level problems with other units.Looks like too many “Monday morning” products are produced. AND over 3 weeks later I am still waiting for my money back from Amazon.

A total waste of money. This is the second synth by Behringer I've had to return. It was completely out of tune with itself. some adjacent keys played the same note octaves were out of tune polyphonic mode was laughable as it was completely out of tune and tuning the oscillators was impossible. it seems that Behringer has no quality control. Absolute jokers.

As an senior player i cannot see how this can be playably polyphonic. There are ways to sort of make it nearly possible but its not the flick of a switch. The synth is very good but if you expect true polyphony buy something else.
