Random Video: The Doepfer A-160 Clock Divider As Sequencer

I only recently found out that someone on MuffWiggler has created an impressive list with all kinds of Eurorack video tutorials. 

This list is being updated regularly, because i also see some of my own recent videos in the Doepfer section of the list.

One of the more interesting videos i stumbled upon there was a year-old video by hiawogice from YouTube that shows the use of a Doepfer A-160 Clock Divider as a nifty little stand-alone sequencer module.

Module A-160 is a frequency divider for clock/trigger/gate signals, particularly for rhythm uses.

At the outputs, you have access to the sub-divided clock signals, from half the clock frequency down to 1/64.
The Clock Divider can be used in combination with the A-161 Clock Sequencer to produce stepped sequences with a length of from one to eight events.

This video shows you can also have a lot of fun without the A-161 module...

Using an A-115 For Complex Waveforms

The A-115 Divider module is very useful to create 'complex' layered basslines, and I use it a lot in my patches.

This module adds 4 separately mixable sub-octaves to your original signal, where F/2 = half the frequency = first sub-octave, F/4 = quarter frequency = second sub-octave, and so on...
Especially if you turn up the original oscillator source up a few octaves, you can get very nice results.

My latest PatchPourri video demonstrates a basic patch, where the original A-111 Oscillator (a square wave, driven by an MAQ16/3 Sequencer) is turned up 4 octaves before it is send into the A-115 Divider.
The A-115 can handle any kind of input waveform, but note that the 4 sub-octaves outputs are all true square waves, so the output provides 4 square waves plus the original signal.

Added filtering will bring even more color to your mixed signal, from here you can route it to anywhere in your system...

Using an A-174-1 Joystick for WobWob

I'm not sure how to name my latest collection of short basic tutorials yet, but i am considering the name "PatchPourri" for this weird collection of short basic patch-ideas.

My latest video shows how you can simply use an A-174-1 Joystick for dubstep-like effects.
The idea comes partly from blogpost i wrote about Dmitry Shtatnov's DIY-fader, but i used this patch before on several other occasions.

In the video a 2-note sequence from the MAQ16/3 controls a standard A-110 VCO.

I connected the X-output from the joystick module to the CV input of a VCA, and the Y-output controls an A-121 Filter (lowpass mode).

Very simple, very basic... off course you can expand this in all kinds of ways.

Have fun experimenting!

Using a Doepfer A-145 LFO as Swing Generator

I have decided to make a few short tutorials for the blog with relatively basic tips for your modular synthesizer.

The first video in this series shows how you can use an LFO as alternative 'Swing Generator'
I used a Doepfer A-145 LFO to show the principle.
The A-145 can do a great job as a (continuous) envelope generator, especially when using the reversed saw-tooth wave.

In the video the TB-303 is playing, the A-100 is playing the same pattern via the TB-303's CV Output.
The Gate from the TB-303 is fed into the Reset In on the A-145 so each time this module receives a Gate signal, it starts a new cycle.
Slow LFO cycles (Low mode) will result in longer envelopes and faster LFO's will result in interesting (swinging) rhythmical discoveries.

Korg Monotron Demo by PatchPierre

As most of you know, i bought a fully analog Korg Monotron -analogue ribbon synthesizer- a while ago.
I promised you to make a short demo of it as soon as i had the time, so here it is.

The Korg Monotron is a cheap (39 Euro) battery-powered synthesizer, but what a lot of fun i already had with this little thing.
It features one VCO, a real VCF (This true analog filter is taken from the classic MS-10 & MS-20 synthesizer) with Filter-Cutoff and Peak (resonance) Control.
An LFO with variable speed (and an LED that flashes in tandem) can be applied to the Pitch (VCO) or Filter(VCF)
*note: only the LFO>filter cutoff is shown in this video
