"Just finished building a few Toppobrillo dual 281s with some grayscale panels. The clip shows various functions as well as demoing the addition of a manual trigger envelopes and push starting the LFO (a known issue with the build). The addition of an illuminated pushbutton switch add to the overall module's 'playability'."
"Dual 281 Function Generator w/LED trigger switch mod (Eurorack)
The Dual 281 is an ASR/AR/LFO generator with voltage controlled inputs for Attack and Decay. This essentially half of the original Buchla 281 but designed for Eurorack Format modular synths. Make Noise's Maths was designed to mimic the 281 and Serge's Dual Universal Slope Generator. Several of these were built for a non-paying customer and now just trying to recoup costs on this last one. These were built with grayscale panels using Toppobrillo PCBs and offered to the DIY community. Wima caps used throughout with the exception of the 1.8nF film caps (Kemet). NKK switches long life switches, long life and low ESR caps for power decoupling. Blue LED switches allow for playing the module in real time...The FG can be triggered by finger. Check the vids. These were only mounted in a lab case and burned in for extensive testing."
"http://www.senode.org – Senode is a new Graphical Music Sequencer! You can create interactive compositions and perform your music live using MIDI or OSC controller messages.
Music and Performance: Sebastian Arnold (http://www.sebastian-arnold.net)
Simply draw your notes, samples, chords effects or song structures as nodes and interconnect them. Senode will choose a path through your composition and play the events at your own tempo or synced to incoming clock. Be inspired – your are the musician, the graph is your score!
We plan to release Senode for Windows, OSX and Linux with and plan future support for iOS, Android, VST and AU. More infos coming soon.

X1L3 - Circuit bent Yamaha DD-10 - evolving percussion
Published on Jun 26, 2015 manufacturedZ3R0 .
"Improvised percussive set utilising the internal sounds and the additional oscillators that have been added. The oscillators can be set to drone or to follow the amp envelope of the output as shown here. A very simple drum pattern in order to show how much this can do on such a basic foundation."
X1L3 - Circuit bent Yamaha DD-10 - power electronics / noise wall
Published on Jun 26, 2015
"Improvised set of PE / noise wall and ambience generated with the embedded oscillators and fx in the DD-10.
Since the DD-10 is near 'unbendable' and seeing a modified one is a rarity i thought i'd give it a go and see what i could come up with."
"Circuit bent - midi retrofit - yamaha DD-10 drum machine.
Modifications and embedded circuitry:
Analogue resonant filter with high pass and low pass bands
Gain, resonance, low pass/high pass toggle and cutoff
A nice warm filter based on the synthacon.
Lot's of resonance and a unique character of it's own.
Violent, squelchy and crunchy when overdriven in this machine.
Digital 'death industrial' delay
Rate, noise, feedback, off/on toggle
This delay variant is based on the formula applied and the output of circuit bent delay pedals which have been sold in the past.
A versatile and if desired aggressive set up that can drift between ambience, echo and all out harsh noise wall and power electronics.
Analogue distortion
Dual mode distortion with diode clipping, filter and gain.
PSU - DC hum suppression circuitry
A regulated psu is now built into the machine.
This gives a stable and quiet power supply to both the drum machine and additional circuitry as well as
providing a quiet output and excellent noise floor.
Input voltage is +12V tip positive running 2 amps.
Please be aware of the amp rating of your adapter. It MUST run 2 amps or above.
Suitable adapters are available at low cost on ebay.
If shipping within the Uk i will suppply and adapter free of charge.
Master pitch control
Gives a large global pitch range - demonstrated in the demo videos The pitch has a high and low setting and a coarse and fine control. The fine control gives you conventional pitching of the drums, the coarse will take them down to vicious noise, droning and glitching. The drum machine now serves not only as a percussive instrument but a generator of abstract sounds and textures.
2 X Drone oscillator section.
The oscillators can be set up as drones or as amp envelope followers. In the first instance they turn the machine into an interesting drone and noise synth, with the features of the FX chain at hand to liven things up. In the second mode they add a tone to the drum patterns which will follow the amplitude of the pattern envelope and add a low end growl to the pattern when the distortion is engaged. Both modes are demonstrated in the videos below.
External input and mixer section.
An external input has been added which has line level and pre amp selection. You could if you wanted to plug a guitar or microphone into it now and apply the effects to the incoming signal. You can also mix this external signal in with the drum sounds and oscillators via the mixer section. Everyhting can be faded in and out as desired.
Cnc machined aluminium panel work with black anodize and engraved text and graphics
The DD-10 comes with midi as standard. It has a good and varied range of sounds and although it can't glitch as with a lot of other old DD drum machines it's been reworked here with a number of additional features to give it a warped character which can hold it's own when put side by side with the machines which are open to rom glitching. It's quite unique in how it behave and sounds now. They're something of a rarity in modified form due to how difficult they are to modify. With some forethought and synth diy application it can now hold it's own amongst the most unruly and bizzare of circuit bent instruments.
Watch the demo videos below for some examples of what it can do.
The first video is a very simple percussive pattern. Intentionally simple in order to show what the machine can do with something very basic. The second video is an improvised noise set. Constantly shifting and evolving. Quite violent at times. It shows what the DD-10 can now do outside of the confines of it's original drum machine format. Harsh noise wall, ambience, fx and power electronics are all within it's grasp."
"It is a lower serial number with the better J-Wire keyboard
Everything works, sounds awesome, starting at a fair selling price...only one issue, you can see the plastic shielding is coming off a little bit on the power cable where it goes into it, not a big deal, I have seen pro one's with much bigger problems sell for this much."
