Doepfer A-100LC3 Low-Cost Case Announced

Quite fast after they released their A-100BP case, Doepfer has now announced another new case to house your eurorack modules.
This time it is a low-cost case that will probably be available from the end of 2013.

Doepfer A-100LC3 low-cost case front view
The A-100LC3 is the "small brother" of the low cost case A-100LC6 (and A-100LC9).
It is very similar to the A-100LC6 but offers only one row with 84 HP for installation of modules. 
The A-100LC3 is equipped with one power supply (1200mA) and one bus board. 

Because of the limited space the power supply of the DIY-Kit #1 with an external transformer is used (same as for the DIY-Kit #1). 

Doepfer A-100LC3 low-cost case
On the left side of the case the connector for the external transformer is located.
The external transformer is not shown in the above pictures. 
The outside dimensions in mm are about 445 (width) x 160 (depth) x 150 (height). 

The price of the A-100LC3 will be around Euro 180-200 (including external power supply for 230 or 115V AC, without modules).

One of the benefits of having the connector on the side of the module IMO is that it can also be used on its back, as some kind of (high) skiff, but I wouldn't look up strange if Doepfer soon announces a skiff or another case...

Intellijel Metropolis Preliminary Info

One of the most interesting modules i have seen in a while has been sent out to various testers in the last few weeks.

The original:
RYK M-185 Sequencer
The Intellijel Metropolis is a 'complex multi stage pitch and gate Eurorack sequencer', based on the RYK M-185 sequencer from the early Roland M-100 series.
This RYK module has always intrigued me, and i was always hoping someone would bring this style of sequencing/programming to the Eurorack.
(Watch some of the original RYK M-185 demos HERE and HERE)

Intellijel worked out an agreement with RYK earlier this year to create this only official Eurorack adaptation of his brilliant sequencer design.
It has taken many months to procure all the special parts and the design has already gone through several hardware revisions. 

Looking at the prototype picture that i see floating all over the internet, i see it has a quite lot of extra features.
It's a big, space-consuming module (34HP wide) and it looks very impressive with its rows of sliders for pitch and pulse count, the switches for different gate modes, and buttons for slide on/off and skip step.
All the core original M-185 functions seem to be there...(Read more here)
On the left side of the module is a 5 digit LED screen, buttons for complex programming/editing and a few knobs for AUX-levels, Gate- and Slide-time plus one for data input.

Intellijel Metropolis Sequencer
Some of the features :
-Sequencer modes:
Forward, Forward-fixed, Reverse, Reverse-fixed, PingPong, PingPong-Fixed, Random, Random-fixed, Brownian, Brownian-fixed
-TB-303 style slide (constant time portamento) with adjustable time
-Stage skipping (double click slide buttons)
- Internal quantizing with selectable scales and keys
-Can act as a master clk with BPM control or slave to an external (using clk src function)
-Save/load panel settings
-shuffle
-Internal clock divider
-Sync output (sets output pulse on last clock step of a sequence, used to slave other sequencers via reset)
-Two assignable AUX inputs which can control: gate length, transpose, key shift, root shift, sequence length, and step divisor.
-config menu to set slider pitch range, clock div type, clock offset
-tap tempo when in internal clock mode and tempo lock with bpm detect in external mode.

-All menu actions are one level deep. i.e. press the menu button and spin the encoder.
There are no hidden levels or sub menus.

" First go around with the Intelljel Metropolis. This is a pretty basic setup; I didn't get into using the aux inputs to modulate things within the Metropolis. I'll try that next! As you can see though, the Metropolis really lends itself to performing and improvising. Very hands-on and easy to go all sorts of crazy ways, melodically. Similar to the Rene, in that regard, but from a totally different point-of-view.Patch notes. Pamela is sending clock to Metropolis, Trigger Riot, Modcan Dual Delay, and Sound of Shadows.
Metropolis is sending the same note info to three different oscillators. The third one going through a uScale first to create intervals. All going into the Dubmix. The Trigger Riot is controlling Tiptop drums, mixed through a VCA Matrix then an M277 for a little grit. That's into channel 2 on the Dubmix, where I add a little Spring Reverb at one point.
The kick and snare are ultimately doubled with the Cwejman BLD and DPO. Lastly, I dialed into some sustained notes on the Pressure Points and a Modcan Triple OSC. The uStep is advancing the Pressure Points.
I had some troubles with the Trigger Riot losing sync when I would change presets.
I'll have to delve into that some more."

Random Video: Modular Synth - A-143-4 and A-149-1 Orchestral(ish) Sounds by IsVisible

Here's the latest modular synth video by IsVisible.
It's kind of orchestral-ish and features Doepfer's A-143-4 and A-149-1 modules.

Video: Modular Synth - A-143-4 and A-149-1 - Orchestral(ish) Sounds
Modular Synth - A-143-4 and A-149-1 - Orchestral(ish) Sounds from isvisible on Vimeo.

" Here we have the Doepfer A-143-4 Quad VC/LFO/VCO triggering the A-149-1 Random Voltages. The A-143-4 is also triggering the A-143-2 Quad ADSR along with providing a little cv to the A-110 VCO's.
All in all with a little filtering courtesy of the A-106-1 Xtreme Filter (Korg MS-20 inspired) and the A-124 Wasp (erm... a Wasp clone) it sounds a bit orchestral, in an abstract kinda way anyway.
Both line outs from the modular (bassier / brassier low end and plucked / reedish higher end) are going directly into a lovely old Tapco 4400 Dual Reverberation System then to my mixing desk where the audio is taken from."

Quick Tip: Differences in Eurorack Modules

When you have multiple modules of the same brand and type , you might sometimes experience small differences between those Eurorack modules.
Sometimes oscillators are tuned differently and you can't get them to match.
One may sound lower than the other with each's controls identical, yet they sound different..
This is often not something to worry about.

Four A-110 VCOs that look the same,
all sounding (slightly) different.
Although most modules are thoroughly tested, some batches may indeed sound a little different due to (internal) trim-pot settings, differences due to tolerances of the electronic parts, etc...

If you want to compare your modules, it is always smart to check the production date/ batch number on the test label and/or on the PCB (version nr) first.
Usually this can be found at the inner side of the front panel.

If the numbers match, and one of your modules does sound different than the other one, you might check out the trimming pots on the backside of the module on the PCB.
In most cases this can be easily fixed with a small screwdriver once you located the right potentiometer (often printed on the PCB or can be found in a manual).

Sometimes it just has to do with other components.
During the production-years of a module the values of all kinds of parts of your module may have been changed a bit (for example R77, R86, R88).
These differences can sometimes be audible, sometimes only to the trained ear...

Especially the specifications of a main circuit like the 74HC4046 (Used in the Phase Locked Loop - A-196 PLL module) may differ for different manufacturers (even different batches from the same manufacturer) of this circuit.
Because the PLL module is not a precision module like a VCO there are no trimming potentiometers available to balance such tolerances.
You'll just have to live with that...

Creating Two Sequences With One Doepfer A-160 by Frederic Gerchambeau

The latest video from Frederic Gerchambeau features quite an interesting pattern, generated by two different sequences from a single A-160 Trigger Sequencer module.

Video: Creating two sequences with one Doepfer A-160

" With only one Doepfer A-160, it's possible to get two different sequences at the same time. For even more fun, i have used two LFOs to trigger that A-160.
Basically the patch is that one :
Two lfos > multiple > A-160 Trig in
A-160 outputs (x 6) > 3 into mixer 1 and 3 into mixer 2
Output mixer1 > VCO1 and output mixer2 > VCO2
Outputs VCO 1 and 2 > VCA"
