DrumDokta PCBs are here!

Finally the DrumDokta PCBs are here, and that means the build can finally begin. Great news!

DrumDokta front panels are in

100 DrumDokta panels arrived today, the doorbell rang as I was in the shower of all things. I ran to the door dripping wet to be greeted by my usual parcel deliverer. "Shit, you caught me in the shower" I said. He chuckled and handed over the parcel.

Oh well, all worth it in the end, all that remains is the PCB delivery and the build can start proper.

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.
