HALG-CD 4Mb Memory Card

Note: links to listings are affiliate links for which the site may be compensated.


via this eBay listing

"This card original circuit was fully developed by DoJoe - J. Fenkes and with the great community of keyboard lovers. HALG modified the mechanical, the circuit, and incorporated couple important changes:

✔ The 3 main slide switches that are on the back of the card are stronger now;
✔ The components placement are fully located inside of plastic cover to protect against ESD (electrostatic discharge)
✔ A card enclosure was designed to protect the card when you need to carry around
✔ A plastic case now fits perfectly to cover components and switches;
This memory card is a replacement for Roland’s M-128, M-256 and M-512 cards, as well as the electrically compatible Akai BR-16 and BR-32 cards. Compared to the original cards, this card has two advantages:
✔ It does not require a backup battery. It uses magnetoresistive RAM for storage rather than
regular static RAM, which is a type of RAM that can typically keep its data for twenty years
before it needs to be refreshed.
✔ A single card actually stores 16 M-128 / M-256 cards or 8 M-512 cards, which can be
accessed by a pair of convenient switch sliders at the rear end of the card.
✔ Like the original card, it also comes with a write protect switch.

Additional NOISEBUG Listings

"Here we have a custom circuit bent Texas Instruments Speak & Spell.

Operates as a totally normal speak and spell until you flip a glitch switch or turn a dial, etc.

Very fun to play, no right or wrong way to it, this bent talking synth is capable of tons of new sounds for you to record, sample or play live.

The added mods include:

1) Tone Oscillator button-creates a tone when depressed, the tone can then be manipulated with the theremin pitch cell, pitch dial or pitch body contacts.

2) Active Matrix Glitch-This mod opens up the membrane for random glitching dependent on where you touch the pad.

3) Ramble Glitch-Flip this switch and hit go and it will spew constant ramblings on and on and on and on.........

4) Dual voice glitch- causes it so speak In both a high and low voice at the same time.

5) Pitch Changing Body Contact-Touch this to lower the pitch, the harder you touch the further the change.

6) Pitch Changing Knob-Use this pitch control to change the pitch from incredibly high falsetto to super low, 8-Bit crushing growl.

7) Reset Button-Use this when you're ready for a change and the machine is rambling on its own, also serves as an OFF button.

8) Theremin Opto Cell Controller-Simply flip the switch, use the pitch dial to fine tune and you can play any sound emitting from the speak like a theremin, makes for some great effects.

9) Loop Switch with Advance Button-FLip this switch at any time to catch a sound that you can then mold and play with the other controls such as the opto cell and pitch dial.

10) Strobing LED for cool effect

It now features a 1/4" output jack that mutes the onboard speaker, allowing you can output this into your effects, amp, pa, etc.

These mods add tons of versatility and droning textures for your playing, recording and experimenting pleasure."

Synesthesia Corp Pipes MK1 Desktop Sound Module SN 83/300

Note: links to listings are affiliate links for which the site may be compensated.
video upload by Pipes.Rocks - 7 years ago

Spotted this one via the Perfect Circuit listing below. Note the video above is from 7 years ago and the videos below from roughly 6 years ago. I'm not finding any newer demos. The last update on their Kickstarter campaignwas from 3 years ago. Curious what ever happened to it. If you know, feel free to comment.

"Pipes is a new audio platform which out-horsepowers a laptop, outperforms any sample player, and is built to get even better over time.

Imagine the audio quality of a high-end audio interface combined with the fastest and most powerful sampler engine ever created. That’s Pipes in a nutshell, but it’s only the beginning.

Based on groundbreaking core technology, Pipes is a new category of machine for creating music and performing live. It has the convenience of a touchscreen tablet style interface, the flexibility of an open source software platform, and the durability for going onstage night after night. Best of all, it’s priced at half the cost of the latest smartphones and updates are free forever!"

Pipes gets bent! Behind the scenes at the manufacturing line.
video upload by Pipes.Rocks - 6 years ago

"Heavy metal being bent into its final form right here in America. While Pipes is a device we haven't seen before, there's still plenty of classic, tried and true ways to build an enclosure right. Take a look behind the scenes as the crew takes the pre-drilled flats and score/bend to create the enclosure. Not pictured is the second piece which comprises the bottom and left+right sides.

When we dreamed up Pipes, we knew that it had to be able to withstand the rigors of touring. While some people may only use Pipes in the studio, many of you will travel with it. We focused on an outcome that prioritized durability, that ensured proper ventilation, and that had enough weight and substance for withstanding exuberant live performances. That said, it's still a computing device, so definitely try to avoid dropping it or getting it wet!"

Oddment ODD-1 Build Update & Demos


video upload by oddment

Demos

video uploads by oddment

Playlist:
1. ODD-1 Overview: Playheads
For a long time now we have tried to live by the words of the great Michael Bolton from the movie Office Space, "why should I change when he's the one who sucks?" But language evolves, and unfortunately, the word “grok” has taken on associations that are problematic. Oddment has evolved too. Starting from one quirky product idea, in 3 years we have grown and are now ready for manufacturing and fulfillment of this product, with ambition to make it the first among many. So with much consternation, we have decided to drop the name groc. When we thought about a new name, we thought that what we have is a little unusual, perhaps a little outside the norm...you might even call it, the ODD-1. This is the first in a series of videos to show all of the ODD-1's functions in more detail. In this one we show off half of the encoders that control the granular synthesis engine - the PLAYHEADS function. Here you can control the level, starting point, tuning (aka pitch adjustment) and playback speed for up to 4 different granular playheads. The auxiliary functions available on the touch screen introduce random variability in different ways.
2. ODD-1 Overview: Grains
This is the second in a series of videos to show all of the ODD-1's functions in more detail. In this one we show off the second half of encoders that control the granular synthesis engine - the GRAINS function. Here you can control the size, spacing, left-right placement, and grain window shape. Each control also has a related function, introducing grain size variability, spacing jitter, binaural scatter, and a front-back bias for the window shape. The auxiliary functions available on the touch screen control a bandpass filter that can be randomized per grain and adjust whether grain size is regulated in the source sample or in the output signal, which can have a big impact on sound characteristics.
3. ODD-1 Overview: 03 Envelopes & Time Path
This is the third in a series of videos to show all of the ODD-1's functions in more detail. In this one we show off the ENVELOPES function. Here you can control the note amplitude envelope and timing, access 3 envelopes that can be used as modulation sources, and use our unique TIME PATH feature to dynamically adapt the playback speed.
4. ODD-1 Overview 04: Sample
This is the fourth in a series of videos to show all of the ODD-1's functions in more detail. In this one we show off the SAMPLE function. Here you can choose a sample from the factory library or user-uploaded samples, control the playback mode and the section available for granulation, play and hold notes, set loop points and interact with pitch, tempo and channel information of the sample. We also show the auto pitch and tempo alignment features.
5. ODD-1 Overview 05: LFOs, Macros, Patching
This is the fifth in a series of videos to show all of the ODD-1's functions in more detail. In this one we show off the LFOs, Macros and how to create modulation connections. There are 4 LFOs, 3 Envelopes, 4 Macros (assignable knobs), 4 Control inputs and MIDI information that can all act as modulation sources. Any parameter on the device is a parameter destination. Unlimited connections are made by holding down a destination parameter and then pressing or twisting a modulation source.
6. ODD-1 Overview 06: Filters, Saturation, Echoes
This is the sixth in a series of videos to show all of the ODD-1's functions in more detail. In this one we show off the Filters, Saturation and Echoes modules. Two filters and two saturation modules per voice, both with multiple types of processing and modulatable parameters, allow for transformation beyond the granular engine. Two echoes sections with filtering and distortion in the feedback loop and fully modulatable parameters make ODD1 worthwhile just as a modular effects rack!
7. ODD-1 Overview: 07 Layers
This is the seventh in a series of videos to show all of the ODD-1's functions in more detail. In this one we show the dual Layer functionality. Essentially the entire system is duplicated so the ODD-1 is like having a dual modular systems, each with a polyphonic granular engine feeding two filters and two non-linear processors per voice, with 3 envelopes, 1 time path, 4 LFOs, 4 Macros and a independent modulation matrix per layer. In these examples we also remind that granular can easily do subtractive-style synthesis when using a basic waveform as the source sample.
8. ODD-1 Overview 08: Reverb & System
The final video in our eight-part series on the ODD-1's functions focuses on the upper-left row where we have global volume, system-level reverb and can work with banks of patches.

The reverb is a classic matrix-style parametric reverb. Think of it like a whole set of interacting delay units with slowly modulating delay times. Ok now that you have that in mind, that's it, that's what it is. It sounds sweet.

If two layers of modulating, granular goodness with a fantastic reverb on top wasn't enough, how do banks of patches to store every twist and connection sound?
And from their newsletter:


What’s in a name?

For a while now we have tried to live by the words of the great Michael Bolton from the movie Office Space, "why should I change when he's the one who sucks?"

But language evolves, and unfortunately, the word “grok” has taken on associations that are problematic.

Oddment has evolved too. Starting from one quirky product idea, we have grown in three years and are now ready for manufacturing and fulfillment of this product, with ambition to make it the first among many. And with much consternation, we have decided to drop the name groc.

When we thought about a new name, we thought that what we have is a little unusual, perhaps a little outside the norm...you might even call it, the ODD-1.

And we plan to keep that off-beat attitude. We hope that brightly-colored friends, ODD-2 and ODD-3, will be along to join ODD-1 after not too long.

Build Updates

We have a lot of exciting progress to report since the last time I wrote. Hop over to our YouTube channel to check out a build update video and some in-depth functionality demos.

We debugged and fixed several problems with the circuit board including the power-up, line input and output, and noise on the control signal inputs.

We got several bids from contract manufacturers in the U.S. and around the world and selected Soldered, based in the E.U. They came highly recommended, and we think their experience will be a huge asset as we go into production.

We worked with Martyna Alexander to tweak the graphic design of the front and back panel. We are thrilled with the updates, including our new company and product logos.

We have first iterations of our custom firmware, enabling full functionality of the device and full USB connectivity to a host computer.

We have completed first versions of the software that include all audio, MIDI and system functionality we intend to support for the release. After many months of playing and testing we re-organized a few functions to expand both the number of concurrent grain “playheads”, and to support banks of patches intended for convenient switching and management in live performance.

What’s Next?

Pics and details via Perfect Circuit

The Solarfaze from Vongon is a stereo 3-band saturator and detune/chorus pedal that gives you exacting control over the frequency landscape of your signal. Whether you're adding a bit of undulatory warmth and saturation or assaulting the frequency spectra of your choice, Solarfaze as you covered, often surprising you with its tonal complexity. The heart of the pedal is a 3-band Bass, Mid, and Treble saturation mixer with each section offering three levels of gain: Soft, Boost, and Hard. Each band can be finetuned to one of five different frequencies, making this pedal as versatile as you are.

The Detune section offers a simple interface for adding movement and interest to your signal, affecting the stereo field, as well for a satisfying binaural experience. Adjust the Amount and Mix to your taste and turn up the Envelope control for dynamic expression that is based on your playing. Size can be adjusted as well to create a smoother or tighter detune effect. Other features include a built-in Noise Gate and an effect rerouting option. Indeed, the Solarfaze is a wonderful addition to the already incredibly Vongon lineup and is sure to find a use in any pedalboard.

SOLARFAZE FEATURES

Stereo multi-band saturator and chorus
Soft-clipping waveshapers for smooth transition from subtle warmth to heavy breakup
Bass, Mid, and Treble drive sliders
Selectable gain level per band: Soft (0dB), Boost (+6dB), Hard (+12dB)
Each band has 5 different frequency options
Stereo detune chorus with independent left/right pitch shifts
Envelope modulation of detune amount for dynamic stereo animation
Route Saturation into Detune and vice versa
Built-in Noise Gate with adjustable threshold
MIDI Input for parameter control and 9 preset storage

Complexe PWM with the TRICOMP - Eurorack module


video upload by LARIX ELEKTRO

"After a comparison with the TIME-SHIFTER (see the last video) [posted here], let's go back to the TRICOMP alown, this time at audio rate.
The basis for creating a square wave signal is to use a comparator, starting from a sawtooth or triangle wave. Ok, this is in all synths…
But what can you do with 3 comparators, along with a whole logic circuit connecting them? ...not to mention, if you only get pulses…

In short, a few examples of using the TRICOMP to make PWM a bit richer and more complex than usual.

Thanks to the excellent ROSSUM TRIDENT, which served as my sound source.

LoFi Future SUPER VEC 1060 Audio Reactive Analog Video Glitch FX Processor


video upload by LoFiFuture



"Available to order here: https://www.lofifuture.shop/product/s...

The SUPERVEC is a heavily modified / circuit bent video FX processor with audio reactive capabilities.

It is based on the VEC1060 video processor / enhancer. The circuit board of the VEC1060 is completely stripped of any unnecessary components from its audio mixer section and corresponding connectors / faders are removed. Every one of the original potentiometers is fully disassembled, cleaned professionally and reassembled with some high quality silicone lubricant so they operated noise free and feel smooth. Lastly the power input and power regulation circuitry is modified to use a standard 12V switching power supply.

This processor is audio reactive via its built in microphone or via the 1/4" line input. There are 3 selectable decay speeds that result in smooth audio reactivity.

The unit features 12 circuit bent effects that can be combined for a seemingly endless amount of variation. With all of the effects off the unit retains all of its original functionality."

Block Rockin' Beats/The Chemical Brothers (Circuit Tracks Version)


video upload by Guinan

"'Back with another one of those block rockin' beats.....'
I've been searching around for an ideal Chemical Brothers track to recreate on the Circuit Tracks when up popped one of my favourite channels, ‪@smallplatesmusic‬ with a video about this classic 1997 song off the album "Dig Your Own Hole'. I've loved the band since their 'Dust Brother'/Playstation 1 days and this mix of jazz, hip-hop and breakbeats blended with their signature synths is a true anthem. (plus check out another great band, 23 Skidoo's track 'Coup' for possible 'inpiration')

See the video here [below] for his fascinating deep dive into all of the samples used and the history behind them. Highly, highly recommend for any music fan...plus also some great Koala Sample App recreations too!

After commenting I was offered access to the Koala track shown in the video, and many of the samples in this recreation come from that version. Mark this up as my first collaboration on this channel! Huge thanks for the inspiration and help ‪@smallplatesmusic‬

What you hear was all recreated on a single Novation Circuit Tracks with the drum tracks used to sequence the various samples, augmented with synth lines to underpin the sound when needed. It was recorded straight from the audio outs into a Zoom L6 without any extra synths or effects.

I hope you enjoy this as much as I did making it and stay tuned!

More details for synth nerds.

BPM 109.
Synth 1 - sawtooth bass synth
Synth 2 - distorted PWM saw patch playing chords and stabs
Drum 1 - drum loops
Drum 2 - sequenced bass note samples
Drum 3 - vocal snatches and pitched gunshot(!) samples
Drum 4 - crash cymbal and 707 open and closed hihats"

Remaking "Block Rockin' Beats" on Koala Sampler

video upload by small plates music

"Back with another one of those..attempts to remake a dancefloor classic on my phone.

This early Chemical Brothers banger includes a lot of jazz, funk, soul and early hip-hop samples including Schoolly D’s raw intro, Wilton Felder’s (very technical...) bassline, and Bernard Purdie’s funky drum fills. I have a listen to the sample, tell you some interesting things I found out, then try to rebuild the track using Koala, showing you how it works (more or less).

Featuring nods to Grand Wizard Theodore, Afrika Islam, Adult Swim cartoons, and the Zulu Beat Show.

0:00-0:15 Intro - What are we doing here anyway?
0:23-1:10 Schoolly D "Back With Another One Of Those" vocal, Acqua Teen Hunger Force

MACHINA BRISTRONICA w/ Stromkult


video uploads by Stromkult

Playlist:

1. MPE on Supercritical Synthesizer Redshift 6 - Bristonica 25
Now capable of MPE!

The latest Redshift update introduces MPE functionality.
This feature, which addresses frequent customer requests, enables compatibility with MPE-capable controllers, such as the LinnStrument.
2. Verbos Electronics Multistage 16- Bristronica 25
New evolution of the Voltage Multistage, one of the first Verbos Modules.
The original Voltage Multistage has an analog sequencer core with several unique features that allow it to function as a sequencer with switchable slides on each step, multistage envelope of any length with sustain on any stage, any shape of LFO, voltage quantizer, and more.

The Voltage Multistage 16 is no longer based on a CMOS counter core, but is built around discrete transistor stages, which enables gate inputs on each stage. This allows external gates to jump it to any stage, multiple loops and sequences that start at one stage and then enter into a loop later.
3. Ohm Force Bohm - Bristronica 25
Explore uncharted kick territory. Choose from nine unique models (and counting) and let the randomizer surprise your creativity. Precision sound-shaping knobs with wide sweet spots make flawless tweaks effortless.
4. TouellSkouarn - Bristronica 25
Gael is revealing the modules that are currently housed in his suitcase. Including the Strakal Brulu and the one and only Germanium Mixer. If you check the prices of old Germanium mixers, such as the Siemens, you will see that this one is a real bargain. As always, there is a lovely sound at his booth; no sine is allowed to pass through this Eurorack system.

TouellSkouarn: Squaring your sines since 2010
5. Crosspatch Triggerpad Updates - Launchpad Sequencer - Bristronica 25
Mitja tells us the latest news about his module at this year's Machina Bristonica. The Triggerpad module converts your Launchpad into a standalone Eurorack. This allows you to repurpose an older Launchpad that might be gathering dust for your Eurorack system. The workflow is super simple and hands-on. You have features such as polymeter per track, swing and micro steps at your fingertips. The new features are BPM modulation and triplets.
6. UDO Audio DMNO 8-voice 2-part multitimbral - Bristonica 25
We have just had the opportunity to take a first look at the new, innovative synth from UDO Audio: the DMNO.
Here's a short interview and sound demo from George!

Features:
8 voice polyphonic, with 4 ‘super’ voices when in Binaural mode. Binaural mode gives each channel (ear) a full synthesizer voice with independent detuning and modulation, creating an expansive, rich and texturally wide sound 2-Part Multitimbral, comprising 2 independent hybrid synthesizers, each with its own dedicated set of front-panel controls
8 selectable ‘Play Modes’ that immediately reconfigure DMNO’s signal flow, redefining how its two independent synth engines interact with one another
7. Teaching Machines FuzzBillon: Numerical Tone Switching – Bristronica 25
Instead of using potentiometers for the device's settings, Teaching Machines uses numerical switches. This offers the advantage of total recall. The effects range from subtle overdrive to screaming distortion and are based on a completely analogue circuit with amplification devices from Germanium to Silicon and light-emitting diodes. Shipping soon!

Born Slippy/Underworld (Circuit Tracks Instrumental)


video upload by Guinan

"This iconic tune (featured in the movie, ‘Trainspotting’) is another classic piece of techno from Underworld. This is a bit of a test if I could get anywhere near the sound using just the Circuit Tracks. The main iconic sound synth was apparently produced using a Waldorf Microwave which is a very different synth architecture than the Tracks.

This version was programmed and recorded straight from the Novation Circuit Tracks.

More details for synth nerds.
140BPM
Synth 1 – Pad sound using Digital Vocal waveforms 1 & 6. The original pad has a very sampled vocal tone from the wavetable used so I mixed in some modulated noise to try and get at least part of the same effect.
Synth 2 – percussive sawtooth chords with delay (apparently dotted 8ths on the original but it didn’t sound right so I’ve used 8th delay (preset 11)).
Drum 1- booming 909 techno bass drum.
Drum 2 – 909 hihats and open hihat.
Drum 3 – this might be contentious but ‘the Internet’ suggests Underworld used a loop from the sample CD ‘Best Service:Dance Mega Jungle Rave’. What you are hearing therefore is sample ‘140 25.wav’ from this set I found by searching online. Opinion suggests that even if it wasn’t from this CD both they and Underworld sampled it from the same source?
Drum 4 – this is reserved for the vocal samples – surprising how essential to the song they are!"

Discover the POWER of Feedback with Isobar's Umbra


video upload by Metamyther

"Discover Umbra, the cutting-edge stereo feedback accumulator designed for adventurous sound designers, new from Isobar. With its unique approach to feedback through a send and return effect loop, Umbra opens up massive sonic possibilities, delivering everything from subtle textures to chaotic walls of sound."

00:00 - Intro
01:20 - Vhikk X Example
04:46 - Drum Example
06:49 - Saturation
07:35 - Multigrain
08:17 - Cursus Melody



"Umbra is a dual channel feedback processor with three discrete transistor core VCA pairs. Route any eurorack-level effects, compressors or filters through its send/return paths to create feedback loops ranging from subtle textured echoes to howling walls of sound. The input level VCA is positioned before the feedback circuit, allowing time based sounds to fade naturally when the VCA is closed. A soft clipping stage after all feedback keeps levels controlled while adding nonlinearities and character. The left-right channel normalling allows for both mono-to-stereo or true stereo operation.

Features:
- Discrete transistor core VCAs for input gain (L and R), VCA pair for return gain, and VCA pair for feedback amount.
- Switchable between stereo operation and serial mono operation, where the output of the left channel enters the input on the right channel, doubling up on feedback and processing, indicated by the color of the LEDs. Orange L and R channels = Stereo operation, Orange L channel, Blue R channel = Serial operation
- Asymmetric diode soft clipping distortion at output.
Level LEDs for input level and return level, to keep feedback, drive and gain under control.

Uses:
- Adding a filter, filter bank, delay, reverb, waveshaper, or any other effect into the feedback loop.
- Heavy soft clipping distortion.
- No input feedback mixing.
- 3 stage VCA with distortion"

X1L3 - ARMALYTE - 8580 SID - 3 voice test


video upload by X1L3

"Progress on the SID chip module i've been working on in my spare time.
8580 SID in circuit.

Took a bit of trial and error making the different write routines needed to do the shared register kinds of things with the filter and stuff. But it's moved on from a single voice proof of concept to an almost fully functioning SID module now.

If you were there when the C64 was a thing, you'll know how good this thing is becoming at pretending to be the chip inside the C64 based on this tune that i knocked up quickly for it. It is pretty much doing what a SID can do in a C64. A nostalgic sound. Especially towards the end where the chip chord trills come in.

The test tune shows the different wave forms and how they sound. It confirms that the absolute ton of continuous data coming in isn't a problem. It shows the ultra fast voice multiplexing to do things like the mellow snare sound after the first four bars, and the not so fast switching in tonal variations later on. It also tells me that the click generated by using the sustain register as a voice volume control is a trivial flaw that can't even be heard here.

Tuning is a bit shabby as i don't have a precision Vref on the breaboard. It's close enough slumming it with the running hot 5v regulator for a proof of concept demo though."
