Demon Seed - Noise Apocalypse

video upload by circuitbenders.co.uk

"Every year we make a pedal to donate to the raffle prize fund for the local Christmas Covers Southsea gig, where various idiots play ridiculous cover versions to raise money for Rowans Hospice and Music Fusion. This year its the Demon Seed!

The circuitbenders.co.uk Demon Seed is a fuzz / distortion / frequency shifting / 8-bit / lo-fi / filth pedal that makes noise in industrial quantities more than sufficient to made deaf people weep.
It utilises the Holtek HT8950 voice changer chip that was designed specifically for use in toy robot voice changer megaphones. The HT8950 converts the analogue guitar signal to 8-bit digital, applies 6 selectable types of frequency shifting or a weird robot arpeggio effect, and then converts the digital signal back to analogue again.
Before someone points it out, yes this pedal was to some degree inspired by the excellent Death By Audio 'Robot' pedal, but with the addition of several features that the HT8950 chip offers but the Robot pedal doesn't use. The Robot is the original HT8950 pedal. All hail Death By Audio!

This demo was recorded using just the Demon Seed pedal and and a clean amp simulator. You'll have to forgive the inability to play the guitar.

We may well have some of these available in the new year."

Modified TR707 with HKA Design ROM switcher

video upload by circuitbenders.co.uk

"A (far too long) demo of a modified Roland TR707 with a HKA ROM switcher installed to give 8 separate sound banks. Different banks are activated by holding down the 1 to 8 step keys as you turn it on.

This was mainly done as a proof of concept to work out if our standard TR7X7 glitching patchbay, individual pitch controls, DAC distortion and decay modifications would work on a HKA modified machine. It turns out everything works perfectly.

CB55 analog drum machine, 16HP eurorack build

video by Jon Petter Skagmo

CB55 is a DR55 clone pcb from circuitbenders.co.uk. You can find addtional posts featuring the CB55 here.

This one was built by http://skagmo.com

"CB55 analog drum machine (16 HP)

This one is popular to mount in Eurorack. I started off trying to make a 28 HP module, but i didn't see the needs for all the modifications/pots I planned, and I thought the module was too large, so I started over and made a narrow (16 HP) MIDI enabled module.
Based on the Circuitbenders CB55 analog drum machine PCB
Cut off the entire trigger conditioning circuit and drilled new mounting holes to allow the PCB to be placed vertically behind a Eurorack panel.
Designed a MIDI and sequencer addon with a PIC18, with a switch on the front panel to start/select predefined sequences, and a DIN-5 for MIDI in. This PCB also has the voltage regulators and power connector, as that was chopped off together with the trigger conditioning circuit.
In addition to the standard volume, tone and accent pots, there are individual volume pots and jack outputs for each of the voices.
Panel was milled from the rear side because I needed to machine some pockets for some protuding tabs on the potmeters, and then flipped over to do the engraving."

Hey there everyone!

Continuing my plans for 2020 and 2021 and the writing my new album, with this i will be posting template jam sessions to YouTube from which I will base and recreate the final tracks. These jam sessions are in no way finalised tracks, but you will be able to hear the main ideas before i start fine tuning the details.

If you join my patreon there will be behind the scenes materials, bonus tracks, stems, sound packs from these sessions and also a possibility to remix the future shortlist single for my release. You will be able to follow the creation of the entire album from idea to final product.

http://bit.ly/BurgPatreon

Track info:

95 bpm slow and dreamy, this one took a while to put together.. most probably due to struggling with similar melodies and vibes from the other two previous sessions. Big thanks to my patrons for pointing that out so i know what to fix. I think that this will have some significant changes for the final version of the track.. and when multitracking it I will most probably change the intro section a bit plus also ensure it builds up in a more cohesive way.

AKAI force, as usual is handling the main drums, sequencing the sub37, monologue, ASM hydrasynth and the volca bass. TR 707 adds some simpler hihats, digitakt adds some extra percussion. Digitone, Peak, Analog Four are not in use.

The ms-20 starts the track off, paired with a long wobbly delay in the el Capistan. At the 3.30 mark i play the dreadbox erebus from the force pads.. a bit tricky but it worked ok. I think the melody will change a bit too, esp phrasing.

Modular does some nice percussion with the BIA, sort of a bass style sound + a pretty weird sequence with the Braids. :)

Enjoy!

Track info:

108 bpm downbeat with light shuffle, focus on a longer buildup for a possible intro section. I might split this into two separate track for the future final recording to make things a bit simpler.

AKAI force is handling drums and sequencing the peak chords, monologue, erebus III and also the main low end bass from the volca. Additional percussion from the TR707, digitakt and the digitone.

First intro melody is on the ms-20, sub37 and ASM in combo does the second one.

Modular does the main intro sequence, 3x doepfer uPVCOs in a triad chord with the help from O_C hemisphere app, also some randomised melodies in the intro to build atmosphere sequenced by the eloquencer, using the classic rings into clouds combo. :)

Roland ROM card patchbox used with a Roland U110 - TEST1

"It turns out our Roland R8/R8M audio grinding patchbox with the fake ROM card interface works on the U110 as well, and by extension probably anything else that uses the same style ROM cards.

Roland R8/R8M patchbox used with a Roland U220

Published on May 8, 2020 circuitbenders.co.uk

"It turns out our Roland R8/R8M audio grinding patchbox with the fake ROM card interface works on the U220 as well, and by extension probably the U110, MV30, U20 and anything else that uses the same style ROM cards.

More info at: https://www.circuitbenders.co.uk/fors..."


"The circuitbenders.co.uk R8 / R8M percussion grinding patch box is an external patchbay case that plugs into the main unit via the sound ROM expansion ports using a custom sound card connected using a 25 way cable as an interface. This allows the creation of circuit bent digital glitching effects without the need to perform any invasive mods on the machine itself. Just plug in the patch box and be immediately transported to a full on jamboree of wall to wall noise terror!

The patch box itself consist of a 20 way main patching area and three combination patchable switches / patching multiples . Connections made between the patchbay sockets result in the digital drum sample data being temporarily glitched causing all kinds of bizarre percussion warping and digital brutality to be applied to the audio. Connections can be routed through the patchable switches so they can be turned on and off at the flick of a switch, or via the patching multiples in order to connect several sockets to each other at the same time.

The supplied DB25 cable is plugged into the back of the patch box, and is then connected to the sound ROM interface card which is plugged into machine via a ROM expansion card socket.

The patch box can be used with either the R8 or the R8M as the sound engine is identical for both machines. Unfortunately due to the fact that the R8 only has one ROM card slot you can't use other sound cards at the same time as the patch box, but with the R8M it doesn't matter which PCM card port of the three available you use, and the other two can still be used for extra sound cards.

Both the R8 and the R8M are very keen on brutally savage, but also sometimes strangely beautiful distortion sounds. It also excels at strange digital gurgling and shuddering sequenced effects on the longer sounds such as the cymbals and some snares. The R8 and R8M take a little more work than most circuit bent drum machines as many of the possible patchbay connections will produce variations on distortions rather than the common effects found on similar machines, but with a little patience there are plenty of interesting and more complex sounds available."

"MAM MB33 Retro with Acid FM mods: This video shows the filter FM mod modulating the filter cutoff at audio frequencies using the internal square and sawtooth VCO waveforms as FM sources. It also demonstrates the Filter Lock mod that holds the filter and VCA open with no envelope, the resonance boost, and the overdrive mod.

The MB33 retro seems to be designed to slightly distort the output stage at full volume, much like the TB303 did. The Drive mod boosts this distortion savagely for some grungy acid techno sounds."

X1L3 - UNDERWURLDE - glitch and delay demo run

Published on Aug 16, 2019 X1L3

"A very 90s era NIN-alike session to serve as a demo. Fitting considering the 90s 'shadow artefact' tech the module is based on :)

The underwurlde is processing a CB55 from circuitbenders.co.uk (link at the bottom) which has been turned into a module in my rig.

What you're hearing for most of the video is the CB55 routed clean to one channel and the realtime processed sound of the wurlde routed to a second channel.

To correct an error in the video text. The third delay section is a grab with a sequenced pitch rise, not a drop. This is how the stepped drop is formed in the loop.

I wanted something familiar and simple to process to illustrate how the underwurlde can transform that basic sound into the sorts of chaotic but refined esoterics thrown out by well modified circuit bent instruments.

Most of the demo is an escallation of the Processing of the CB55. At about 5.15 the underwurlde switches over to serving as a delay.

As a delay it can pull some impressive delay times. It can also act much like an abused pt2399 delay will but with MUCH more finesse. The limit at which the noise bleed and disintigration of the delay loop is much longer, it's capable of sustaining a loop feedback without it disintigrating into noise and if the loop is ramlocked it essentially becomes an infinite delay.

Ramglitching is a spin off of the circuit bending that i've indulged in for many years now. What you have here is something akin to a bent Casio SK1 sampler. You can grab adio, lock it in ram and then abuse it with the glitch array. This is none destructive, if you release all glitch lines then the audio in ram remains intact and as it was when sampled. The main module has three glitch gates and a header at the back that allows you to configure these three gates to the eight data lines according to taste. A 4hp strip will follow some time soon which will allow all eight data lines to be merged for enhanced chaos.

The final section of the run is a sample of me going 'ahhhhhh' into a mic, which is then looped, pitch sequenced and with some restraint, glitched to a rise where the last 'chorus' section kicks in."

X1L3 - MIDI to gate eurorack module + NUX timecore total conversion

Published on Sep 22, 2018 X1L3

"4HP eleven output midi to gate module.

Being used here for drum sequencing duties. Starting out with the CB55 module built with the DR55 clone pcb from circuitbenders.co.uk. An elements is tied to the midi to gate to add an air of melancholy and mid way two peaks are added to escallate the track and nail down the drum section before the track starts to drop out. The last gate is reading a continuous note on/off track from the daw to create a sync clock for the NUX timecore. I alter the time signature subtly towards the end which you can hear in both how the NUX suddenly tries to shift tempo and also the slow delay fade out in the last few bars. A simple demo really, just something to show how much this little module can do. My daw is used for the melodic backing and bass etc. Too lazy to knock it up on the rig today :P

Reads incoming date on Channel ten and responds to middle C up through the next ten notes. Not on will set a gate high and hold it until the note is released, setting the gate low again.

Countless uses for this one. Clocks for anything tap tempo enabled, sequencing duties, adsr triggering etc etc.

Also in the rig here is a NUX timecore digital delay guitar pedal converted to eurorack with homebrew pcb and panel test pieces made on my 3040 cnc router.. It now has input and output buffers to make it suitable for euro level signals and a gate input on the front panel which allows you to engage and disengage the effect or send a clock to it to sync thetap tempo. Really cool delay with loads of modes and a decent sound. The CB 55 drums are fed through this throught the demo. A total conversion kit is underway for anyone wanting to mod their own :)"
