Circuit Bent/Augmented Yamaha Pss-80

video by SMMP

"I always loved the Yamaha PSS-80 keyboard, for its lo-fi, almost 8bit, squarewavey sounds. Given it's polyphony, I thought it would be a lovely keyboard if it had a nice filter. So I "augmented" it (rather than bending it) sticking in a filter (I think based on the old Wasp Synth VCF), add a delay, put an LFO that can modulate either the delay or the filter, and a monster on the left side, some kind of pitch tracking, which I built following some instructions in the CD4046 datasheet, but then creating loops with the signal and lowering it down with a CD4040 frequency divider chip. The switches there and the pots, don't always provide nice results, but when they do, they can shake your pants!


Kawai K5000s Advanced Additive Synthesizer SN 602777 w/ Original Box

via this auction

Additional NOISEBUG Listings

"Unit is in good shape and perfect working order. Synth ships with original box and 4.04 version firmware.

Details The K5000s is a legendary vintage synth due to its highly advanced additive synthesis. You can create patches from this synth unlike anything else: it excels at the icey and cold, the evolving, and the downright unique. A composers secret weapon. The K5000S is an Advanced Additive Synthesizer that combines real-time performance features and unique synthesis capabilities into a single unit.

ADVANCED ADDITIVE TONE GENERATOR The K5000S series updates the famous K5 synthesizer tone generator and its unique additive harmonic synthesis approach. The Advanced Additive Tone Generator contains 32 source generators, which depending on how they are used, can yield up to 32 voice polyphony. PCM samples can also be mixed with additive sources. As few as one or as many as six sources can be used to make a single sound. For example, a PCM wave of a piano hammer can be superimposed with the sound of the piano string created by additive harmonics.

128 BAND FORMANT FILTER A new addition to the Advanced Additive tone generator is the 128 Band Pennant Filter, which can used as a Parametric EQ or several other con?gurations. The Formant Filter is completely controllable by envelopes or LFOs.

MACRO CONTROL Unique to the K5000S model are the macro controls for major sound parameters, available on the front panel for instant access. In addition, four user controls are programmable for each patch.

PROGRAMMABLE ARPEGGIATOR The K5000S Programmable Arpeggiator, features a wide range of control, ideal for use in Tekno and other modern musical styles.

DIGITAL EFFECTS SYSTEM The K5000S contains an advanced digital effects processor (DSP), which allows four individual effects of chorus, delay, distortion, etc., in addition to reverb and a graphic equalizer. When playing a single sound, individual sources can be routed to individual effects; when playing multiple sounds in Multi mode, individual sounds can be routed to individual effects."

Adding the RT-311 Swarm Oscillator to the DELTA CEP A sound engine!

video by Jörg Schaaf

'I describe in detail how the communication between the DELTA CEP and the Swarm Oscillator RT-311get established. After the connection and setup, the RT-311 follows the notes one plays via MIDI with the DELTA CEP A. That means, in paraphonic mode, the RT-311 plays chords instead of multiple oscillators with equal pitch."

Tweaking: Nord Lead A1 (NO TALKING)

video by SYNTHWAY

"Just having fun while making some different sounds with the different oscillator configurations on the Nord Lead A1. You can get the overall feeling of how it sounds and how easy it is to achieve different sounds. No, it's not as deep as the Nord Lead 4, but I made the jump and use it as my only polysynth besides what I have ITB."

Making HUGE Super Saw Sounds w/ the Cobalt8

video by Perfect Circuit

"Grab Jacob’s patches here:​

In this video, Jacob explores the Modal Electronics Cobalt8, a modern take on virtual analog synthesis, specifically showcasing its excellent ability to craft supersaw sounds. After all, how super would your saws be if you had up to 64 oscillators at your disposal? The Cobalt8 even expands on the concept a bit further, offering Spread oscillator algorithms with not just sawtooth waveforms, but triangle and square waves too!

But of course, the Cobalt8 has a bunch of other tricks up its sleeve, and later in the video, Jacob showcases ideas for blending supersaws in with some of the other super cool oscillator modes. While we all love the huge, trance-inspired pads that supersaws are known for, but with some clever patch-crafting, you can find a way to bring these super-sounds into any kind of music.

Still Here (jamming with a tape loop)

video by poorness studios

"Well this was fun. I decided to use my Sony TCM-200DV cassette player to play a 4-second tape loop. I got this cassette from The Void Electronics in Ireland. He does really nice work. I used the Arturia Microbrute and KORG KO-1 Kaossilator to jam along and make some crazy sounds. My Boss RV-6 Reverb and Rolls Multimix II also get involved.

If you like these kinds of loops, check out The Void Electronics on Etsy:​"

Korg DW-6000 w/ Cassette Tapes

via this auction

"The Korg DW-6000 is a six note polyphonic hybrid synthesizer with two single-cycle digital waveform oscillators and one analogue lowpass filter per voice. As basic material, eight digital wave cycle waveforms were available to the user through a system Korg called DWGS for Digital Waveform Generator System. The DWGS system can be thought of as an early sample playback system where only extremely short, single cycle waveforms are stored on four 256 Kilobit ROM chips, played back through the two digital oscillators and processed by relatively familiar subtractive synthesis facilities. Edit the patch is a typical method for selecting the parameter with a single data slider to increase or decrease the value.

This synth is in very good condition and comes with two Korg tapes."

What does it mean to RECAP old gear? | Yamaha TX816 in need of help

video by Espen Kraft

"I recently found out that my Yamaha TX816 had bulging capacitors in the power supply. I was a little pressed for time so Anders Jensen stepped in and offered to do it for me. Thanks buddy!

So he shot the complete job and I shot a couple of clips and presto; here is a nice little video for anyone interested in what it takes to actually replace all the capacitors in a power supply. Necessary evil if you want to keep your precious electronics free from harm and enjoy your synths for another 30 years.
Now I "only" have to recap all the different boards as well, but those aren't as critical as the power supply as a bad power rail there can easily fry everything down the line."

Korg SQ-64 Overview and Demo

video by sonicstate

"Korg’s first Sequencer since the SQ-1 - which came out the same time as the MS-20 mini and was a simple 8 step analog affair. The SQ-64 is an altogether different beast.
It appears to take it's inspiration from the 3 melodic tracks and a drum track, like Beatstep and Keystep Pro from Arturia, but the way it addresses them is different.

RYK Modular - M185 Sequencer

video by SchneidersLaden

"The RYK M185 Sequencer rethinks the concept of 8-step sequencers by adding different options for how every single stage behaves – it can be handled to program ratcheting, short or long gates, pauses or repeats and the like. So, allowing each step to be repeated by up to 8 times and additionally defining how this repetition will be executed, really opened up the initial concept of a simple 8-step sequencer. Each step can perform 8 unique gate modes for creative rhythmic possibilities: off, one gate on first repetition, gate on every second/third/forth repetition, probability, tied gate. If you set the sequence length to 16 or 32 for example, you can fill these steps with unique patterns in no time.

With the addition of A/B split mode for two separate sequences and implementing MIDI I/O the concept of this sequencer was taken even further. Especially its MIDI capabilities qualify this module to be used with all kinds of synthesizers in your studio, not only your modular.

This video shows you example sequences made with the M185 and some parts show you the process of programming simple to complex sequences. This is a very hands-on module with great potential for creating new ideas quickly and it seems to be ideal for live performances with a tendency to improvisation."

CB55 analog drum machine, 16HP eurorack build

video by Jon Petter Skagmo

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

This one was built by

"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."
