DrumDokta DDB2 prototype update

Well those jolly FedEx guys finally got around to finding my shipping, this has caused some delays in the project but things are still on track.

So here's a quick video of the built prototype in action.

Using Maths as a sequential switch for PP+Brains

Ok here's how to make a sequential switch for your PP+Brains if you don't have a Doepfer A-151.

what you need is,

Make Noise Pressure Points + Brains (obviously).
Make Noise Maths.
A clock divider such as the 4MS RCD.
two VCA's with DC coupled in/outputs, such as the Doepfer A-132-1.
Something to make the noise, osc/vcf/vca etc.
A cv mixer or OR-Combiner.
a multiple or stack cables.

Here's how to wire up the patch.

Pressure Points/Brains
----------------------
First patch a clock/lfo to Brains CLK in.
Patch Pressure Points stage one gate to RCD clock input.
Patch Pressure Points ch2 cv out to VCA1 signal in.
Patch Pressure Points ch3 cv out to VCA2 signal in.

RCD (or equivalent clock divider)
---------------------------------
Patch division 1 (or multi the incoming clock) to maths ch1 TRIG
Patch division 2 to a multiple, and patch one signal to maths ch4 TRIG and another to maths ch1 BOTH

Maths
-----
patch ch1 OUT to VCA1 cv IN
patch EOR to maths ch4 BOTH
patch ch2 OUT to VCA2 cv IN

set the maths knobs to these settings
ch1 rise full ccw
ch1 fall full cw
cycle off
ch1 response linear
output ch1 attenuverter to taste (adjusting this will transpose the sequence)
set the maths knobs to these settings
ch2 rise full ccw
ch2 fall full cw
cycle off
ch2 response log
output ch2 attenuverter to taste (adjusting this will transpose the sequence)

VCAs
----

patch both VCA outputs to a CV mixer (or OR-Combiner) and connect the output of this to your vco/vcf/vca setup.

and thats it, have fun!

DrumDokta DDB2 breadboard prototype

Here's a quick look at the DDB2 prototype, this will connect to the rear of a DrumDokta to provide hand claps.

sorry about the camera audio, i'll make a proper demonstation as soon as the prototype pcbs are in and built.

DrumDokta Breakout expansion #1 (DDB1)

Here's a quick look at the first DrumDokta expansion prototype, tentatively named DDB1.

This will add five oscillator outputs, and a four stage OR combiner to the DrumDokta. A useful utility breakout that will enable you to make additional percussion while still playing the standard DrumDokta sounds.

Introducing the DrumDokta DRM-110

So here is the next eurorack offering from DinSync.info, the DrumDokta DRM-110.

At it's core is a 1:1 clone of the old school Boss DR-110. The project started since I was often using more than 50% of my modular just to make drum sounds. Sure there are already drum modules on the market but most take up vast amounts of modular real estate and that's not to mention the price. There had to be a better way I thought.

Then a broken DR-110 came my way (thanks Erwin!) and I thought this could be a good candidate for a module. But alas of course with any 25 year old unit there's always the rare parts. After quite some searching I was able to obtain a decent quantity of them. Seven bread-boads worth of spaghetti later it was time to make some prototype PCBs, a few revisions of those and a test panel or two later and here it is.

The one pictured is the third revision prototype. The production model will have a silver anodized aluminum panel and the depth will be around 10mm less then in the pictures, so it’ll be skiff ready.

As with what seems to be the trend with my modules, this will most likely be a limited edition. The first units should be available for shipping in around two months time so if you want to be added to the waiting list drop me a line on info@dinsync.info to reserve your place on the list.

Anyway I’ll be releasing more videos in the near future showing the module a little more in depth and some of its features as well as posting more information about the forthcoming breakout modules for it.
