Very versatile wavefolder!

Grent, 20.06.2013
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.

Doepfer A-156 Quantiser

Blair, 04.04.2014
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.

Incredibly useful module

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.

Bursting with character

Zoë, 02.06.2013
Spring reverb is NOT like pristine digital reverb. Don't get it for that, but do get it. When added to the end of a patch, you can use it as a strange, otherworldly, organic reverb that leaves a metal taste in your mouth. But this is a modular synthesiser, so you're not confined to that. You can instead put it before the VCA, which stops it being reverb and starts it being a strange little creature that makes your patch sound more organic or real-world in a way that's hard to identify. It stops sounding like a synthesiser and starts sounding like a weird thing that might physically exist. In short, it introduces some complicated real-world physics into the mix.

So let's look at this particular spring reverb by Doepfer. The build quality isn't great, and it might benefit from a little re-soldering. If you're into modular synths, which are a pretty niche market, this probably won't be too difficult for you. It works just fine straight out of the box, but looks like you need to treat it carefully if you're not confident repairing it yourself later down the line.

Having said that, the features are great. The "emphasis" knob EQs the midrange, I believe, making it sound brighter if need be. As well as the regular inputs and outputs, there are extra ones for the feedback loop, so you can amplify the signal to lengthen the tail, filter it with any filter you already have, and so on. These simple features make it very open ended.

I also hear it's pretty easy to swap out the reverb tank -- the physical spring reverb in a metal case, that you plug into the main module -- for a different one, should you want to, for even more possibilities. Personally, though, I haven't found the need: this module is already providing me with so many things to try out, that I've still only begun to scratch the surface.

Spring reverb in general has a very distinctive sound, so check out some examples online before you decide whether this is for you. Personally, I'm making it a big part of the latest evolution of my signature sound.
