Everyone needs a wavefolder. It took me some time to properly grasp this module, but now it makes it's way into almost every patch I make. You can get a huge range of sounds! It's best fed with a triangle or sine as the wave folding circuit adds lots of harmonics to the signal. Adding some slow modulations to the "symmetry" and "harmonics" inputs can create an ever changing sound that never sounds the same twice!

A great tip I learned with this is to keep the input level down low, it is easy to overdrive, and by doing that you may miss the subtle morphing waveshapes that this module excels so well at.

A small issue I have with this is the depth, it's a little bit deeper than most modules so it may have trouble fitting in a shallow case. (No problem using any of Doepfer's excellent racks though!)

I don't think there is another wavefolder that sounds like this. One of Mr Doepfers most unique creations.

Another well built Doepfer module.

This delay is more suited towards Flange and Chorus rather than traditional delay, The clock noise is extremely loud at lowest rates as it doesn't have an internal filter, You will need a high pass filter if you are looking at a clean sounding analogue delay.

Highly recommended module for creative effects, but I would probably recommend another module for traditional delay.

I have the Doepfer A-149 module which generates stored and quantised random voltages. This is great, but soon I found myself looking for a module which would take the output of the A-149 and restrict it to play notes from recognisable scales, such as major and minor ones. I also wanted to create arpeggios which included only notes from certain chords. Research showed that I needed to get a control voltage quantiser, which would select from the random collages only those values that would play notes from chords or scales I had selected.

I bought the A-156 Dual Quantiser after I had checked out much more expensive versions from other manufacturers. The A-156 does not have all the 'bells and whistles' of its more expensive competitors, such as programmable scales and memories. however these devices are at least twice as expensive as the A-156, and I was not looking for extra functionality. A key feature of the A-156 is that it is a dual quantiser - in effect two devices in one. However, the second quantiser defaults to generating semi-tone scales only. This can be changed by changing the position of a jumper on the main circuit board. After that, both quantisers offer the same features, such as notes from a chosen scale or arpeggio playing a certain chord.

The A-156 also includes trigger outputs, which will send a gate signal each time a new note value is generated. This is very useful for 'shaping' the sound, such as triggering a low pass gate to open each time a note is created by the A-156 and played by a VCO.

Are there any shortcomings? Not really. For the price this module performs incredibly well, and it easy to operate. My one suggestion is that the jumper that links or separates the two quantisers, should be replaced by a 2-way switch on the module's front panel.

Great module, highly recommended.

I use this module on nearly every patch I set up. It's incredibly good for turning an LFO or a noise source into note CV and trigger output, all in time with an incoming clock pulse to create surprising pseudo-random arppegios and sequences of notes. The control switches allow for all the random notes to be kept in a specified key or chord rather than being just an unconnected series of notes so this module really helps to fill out a patch with constantly surprising and pleasing flurries of notes.

One thing worth noting is that there is a jumper on the board to set both channels to the same harmonic settings. I found this vital as without it the module will simply default to random semitones which rapidly becomes tiresome. With the jumper set you get more useful root, optional third, fifth and selectable 6th or seventh on major or minor chords.

overall, five stars all the way. I'm expanding my modular all the time and will definitely buy another of these. Highly recommended.
