Doepfer A-143-9

Very satisfied, will never leave my rack

All in all this module is just worth any penny! Here are some pros and cons:

- there are no cons, really

pros:

- the build quality is very good

- i really like the two LEDs which show what is going on

- i really like the concept of having 4 sinewaves in a different phase

- I like that there are two CV inputs, even one attenuated

- I love the range switch, gives a lot of flexibility

- cheap price

- doesnt take too much space in the rack

I use this module in 95% of my patches, my patches are built oftentimes around that module. There is nothing i could complain about that module, really. My patches wouldnt be the same without that module.

I recommend this module to everyone who is into modular.

4 Sinus LFO's at your service.

This module does exactly what you think. It delivers 4 separate sinus waves each set at a 90 degree phase from each other.

So you have 0, 90, 180, 270 degrees.

It has 2 CV inputs to control frequency, CV1 without attenuator and CV2 with polarizer. Consequently the module can be used even as an experimental sine VCO but does NOT feature an exact 1V/oct CV input! It doen't track well, but can be used for effects and such.

It ranges from 0.1 Hz to 3.5 KHz and has the usual L/M/H switch.

I use it a lot to do interesting panning effects and phasing effects.

PROS: Good classic Doepfer build. Simple to use and understand.

CONS: Could have implemented 1 v/oct tracking to further its uses. You can really make some interesting FM sounds with it but you can't play them with CV :-(

it is like having synced 4 LFOs

I use it on almost every patch, it is like having 4 synced LFOs, but phase shifted, so they modify something at different moment in time. Must have!

Affordable LFO

Dieter makes good quality no frills modules.

This quad lfo is just that

solid

Very useful module. Only dropped one star as it is unnecessary wide, as it is often the case with Doepfer modules.

LFO controller

I bought this module especially to give an extra kick to my other LFO. It does its job perfectly, the only cons I have is that the sockets comes loose after a while.

Mmm... Shepard's Tone

I specifically bought this module to help me create a shepards tone. You know, a forever rising or descending tone.

Well this works great.

I've also been using it a lot in conjunction with four sound sources and four VCA's to create slowly morphing soundscapes.

It can also be used as a pretty sweet sinewave oscillator when used at audio rate.

Very useful

This is a very useful and versatile module. I am using it in conjunction with the A 137 2 wave multiplier to give a fat chorus/ensemble effect.
