The Crow Hill Company Introduces POCKET STRING no-barrier-to-entry-styled string library plug-in

video upload by CROW HILL XTRAS

Press release follows:

"The Crow Hill Company creates POCKET STRINGS as no-barrier-to-entry-styled string library plug-in produced without compromise… with added ‘synthy spice’

EDINBURGH, UK: having recently rebranded itself with an aesthetic that truly realises company co-founder and composer Christian Henson’s heartfelt dream of encouraging people to make music and help them on their journey, regardless of whatever point they were at and wherever their journey began, The Crow Hill Company continues its journeying into ‘Season Two’ as a producer of resources and tools to protect, inspire, support, and provide opportunities for music-makers the world over, believing that music is, and should remain, a wholly human experience, one that is by far one of the most powerful forms of expression, escape, comfort, and remembrance, of which its newly-created POCKET STRINGS — styled as a definitive string library plug-in that opens the doors to collaboration between anyone anywhere, creatively combining live cinematic orchestral recordings with some rarefied vintage synth classics made to measure for added body, depth, and character — readily represents the cornerstone of this ethos, as of July 10…

“A string library that’s accessible to all without compromise — a distillation of the last 25, nearly 30, years that I’ve been working as a media composer, which means that I write music for film, TV, and computer games, giving you the very basic necessities to write pro-end string arrangements. Whether that be adding to productions, songs, collaborating with others, or, indeed, creating professional film scores — whether that be to demo for an orchestra to play, or, indeed, to go to broadcast, there’s been no compromises here. But accessibility is the key — not just with the price point, but with usability.” So says Christian Henson himself, perfectly positioned — as The Crow Hill Company’s original founder, forging forward by building upon his extensive experience gained from founding Spitfire Audio to originally offer a palette of sounds he had created for his own use as a professional composer to his film world colleagues by invitation only, though the rest, as they say, is history — to proudly introduce POCKET STRINGS as a never-tried-before strings library plug-in that aims to bring broadcast-grade string possibilities to everyone.

Introducing Pipo Interfaces

A Sneak Peak into Pipo modules video upload by Pipo Interfaces

"Video produced by Tom Bouchet

Music: "Transition" by Alex-Productions (CC BY 3.0)"

Press release follows:


Pipo Interfaces brings a new versatile toolkit for creative sensing and audiovisual interactions in real-time.

Developed by creative technologist Rupert Renevier, Pipo is a range of electronics modules that connect sensors to computers, and are meant to simplify creative interactivity between people, real-world objects, and digital creation.

Whether you're performing, designing experimental MIDI instruments, or interested in making installations, Pipo builds the foundations of an accessible and adaptable open source toolkit.

When digital experiences become sensible and tangible, they allow for greater engagement and connection. The idea of using sensors for audiovisual applications and arts is far from being new, but still requires building custom solutions on Arduino or Raspberry Pi, which tends to be complex, time-consuming, and therefore not easily accessible to most.

Pipo wants to unlock the creative potential of real-time sensing, and lower the technical barrier to it, by proposing tools that connect the physical world to the digital in a straightforward fashion.

The Pipo recipe is simple: small affordable modules, wireless capabilities, and an intuitive yet powerful user interface. All Pipo modules can be used alone or in combination, fixed, worn on the body, embedded in objects, etc... All Pipo modules have mounting holes to augment all kind of projects and casing will be made available.

The first 3 modules of the family are Pipo Motion, Pipo Range and Pipo Analog.

Pipo Motion is dedicated to sensing movement: orientation, acceleration and magnetic field, thanks to an advanced 9 axis IMU (Inertial Measurement Unit). It allows for relative and absolute orientation.

Pipo Range is an accurate distance sensing unit which can be used to detect hands, obstacles, objects, or people (up to 3m). It can be used the same way as a theremin, or as a people proximity sensor for eg.

Finally, Pipo Analog, a versatile Input/Output device. On one side it has 8 capacitive touch inputs to create original touch buttons (for eg: with wires, metallic tape, vegetables, conductive paint, etc...)

On the other side it has multiple analog voltage inputs/outputs (up to 8). With these you can acquire and use any external buttons, specialized analog sensors modules, knobs or control servo motors, drivers, etc...

Beyond these three first sensing modules, Pipo Interfaces carries a vision for a whole creative ecosystem for many more input and also output modules. It has a strong anchor towards open source development and wants to create a strong user community connection.

Pipo modules can all send standard MIDI and/or OSC data wirelessly for maximum compatibility.

The connectivity is made through WiFi, Bluetooth Low Energy, or USB and every module has an onboard battery charger, so that whatever idea you have, you can test it quickly and have it communicate to your audiovisual software in a matter of seconds (no matter your operating system).

All the settings can be tuned in the field through a web interface hosted on every module.
No need for an app or software, just open any web browser on your mobile. This interface allows you to set various settings like sensing parameters, ranges, and to adapt the incoming and outgoing data streams to your needs, quickly and easily.

You can for example eg fine tune the midi output, choose a note scale, channel, etc...

On a technical level, the project is developed with PlatformIO and the Arduino framework to make it easy for people to hack, modify, upgrade their pipos, or build their own custom Pipos. The software is open source, and the project runs on the Esp32-s3, one of the most versatile and powerful IoT chips around.

Pipo will launch as a pre-order campaign to fund the first production run. If you like Pipo, you can support it by entering your email address on the campaign page, it means a lot ! By doing so, you will also be notified of the launch date, so that you can be among the first people to get yours.

The launch date is pending on gathering a critical mass of people who want to see the project going live, so subscribing helps the project move forward.

All this happens on CrowdSupply, a platform dedicated to launching open source projects:

VEMIA is Peter Forrest's auction house. He is the author of The A-Z of Analogue Synthesizer Books.

"SCHOBER TUNESMITH (new start price to allow bids from outside the seller's tax region) Very rare monophonic transistor synth, single oscillator, circa 1968, sold as a kit or pre-assembled. The voice switch activates different static filters, providing 6 markedly different tones from bright sawtooth to mellow triangle. This short video [posted here] of the same model clearly shows the sounds ---- I read that the keyboard is a Pratt-Reed that uses series resistance rather than a matrix. This model for auction has clear strong sound with almost no hum whatsoever. The main problem is the tuning is way off, and some notes glitch a little. Not difficult to repair, I would think. Also the vibrato is not working, probably just a bad resistor, should be easy to fix. Body is solid and in good condition for a 57-year old instrument, so it hasn't been knocked about. Keyboard and control panel are very clean, almost no scratches. Mainly home or studio use, probably. The three tools contained inside the lid are a complete mystery, which may be solved once you look inside the unit! While this is offered as a 'project' the encouraging thing is how bright and clear it sounds, and once tuning and vibrato are fixed, you have a very playable instrument similar to a Clavioline. It's a worthwhile project, I would say. Power is 105-120V 50/60 cycles, with a 2-pin US-style mains plug. I've given it a very low start price. SHIPPING: This Tunesmith is located in Japan, and weighs (packed) approximately 7kg. Discounted shipping to UK/Europe/USA will be £30 surface, £80 air. For other countries, please enquire."

Baloran Introduces TheBumBleBee (aka The 3B)

video upload by Laurent Baloran

"A zen moment at the helm of The 3B.
more informations on https://baloran.com/store/index.php?r..."



Available in desktop and eurorack formats.

Google translated:

The 3B is delivered assembled in its external case: 2mm folded aluminum, 4mm machined aluminum front, epoxy paint, DC/DC converters and Meanwell power supply, the whole demonstrates a hardware quality that lives up to the pleasure that The 3B brings.

On the left (yellow adjustable support) is a 3D Laser/IR, without any danger for fingers and eyes, it is a specific technology called TOF (Time Of Flight). This sensor transmits an image of your hand or any other object that enters its cone of vision, as well as the precise distance between the object and the sensor. The image allows, by analysis, to determine the X and Y position of the hand or the object. The Z height is transmitted directly by the sensor with millimeter precision.

A second identical sensor, placed on the right (blue swivel support), transmits the X2, Y2, Z2 coordinates as well as a GATE G2, allowing completely independent two-handed play.

In the center, two buttons A and B are very sensitive pressure sensors. They transform pressure into voltage available on the A/X2 and B/Y2 sockets. They can operate as two independent sources or as a single source controlled by the two buttons: in this case, button A decrements the value, B increments it and both can act simultaneously to allow excellent control finesse.


Management of height information (Z1 and Z2)

The height of the hand, another part of the body, or an object in relation to the sensor is fundamental playing information and The 3B offers you several ways to manage it.


LIKE THEREMIN mode

When the hand enters the cone of visibility of the sensor, the GATE is activated. The voltage available on Z will correspond to the height of your hand. By default, The3B offers 120mm per octave. With its sensitivity, in broad daylight and without gloves, you cover three octaves minimum. You can change this 120mm reference per octave (possible values ​​72, 96, 120, 180, 240 and 360 mm)


SELECTED SEMITONE mode

Each 10 mm of movement (with 120 mm/octave setting) corresponds to a semitone. The GATE in this mode is generated for each note played. You can activate/deactivate certain semitones to limit the range to a specific key or notes.

Valkure Guitar Organ for iOS and Apple Silicon Macs

video upload by YonacSoftware



"Available now [On the App Store]

Evoke a bewildering variety of polyphonic organ sounds directly from your guitar! Valkurë (pronounced VAL-KUR-EE) transforms your raw strings into a big, multi-timbral instrument in realtime, and without resorting to guitar-to-MIDI trickery. Preserve the crucial dynamics of your playing -such as vibrato, bends, and slides- while maintaining thorough control over the final sound. Complete with a full range of organ parameters, extensive options, built-in rotary speaker emulation, virtual tube amplifier, and analog inspired effects, Valkurë is a powerful addition to your guitar arsenal.

The unique organ module achieves guitar-to-organ transformation via proprietary signal processing algorithms, thereby retaining full polyphony. Valkurë offers three different organ models that vary from mellow to aggressive. The main tone generator features nine registers (drawbars) that allow you to dial in overtones in a five octave range — much like a tonewheel organ. In addition, two special “pedal” registers provide harmonically rich bass and sub bass tones that can work alone or in combination with the principal organ tones.

A built-in percussion generator inspired by “B” and “C” series organs is triggered by pick attack, and features switches for percussion length, level, as well as harmonic. Additional preferences allow you to modify these, as well as specify the sensitivity of the trigger detector. The Chorus/Vibrato unit is modeled after the famed scanner circuit, and features six modes.

The rotary speaker module offers three unique cabinets to choose from. Each cabinet features individually configurable virtual horn and drum drivers. The rotary unit provides many options, including micing angle, inertia, slow/fast speeds, additional room microphone, and more. The built-in amplifier is designed to complement the rotary speaker, and offers three different amp models that feature our newest tube emulation technology, as well as a full range of tonal controls.

The settings panel contains a wide variety of parameters for fine tuning the organ. These include variable attack to obtain an auto-generated volume “swell” effect, as well as thorough control over the organ’s timbre and dynamics via Taper, Resonance, Body, Air, and Leakage parameters. Dedicated variable Boost controls for organ and pedal modules help add fullness and sizzle to the basic tones. Valkurë is rounded out by the addition of analog-modeling effects, including tape delay, 3-band Baxandall style EQ, as well as built in compressor.

Besides working as both a standalone app and an AUv3 plugin, Valkurë is also compatible with Apple Silicon Macs. It comes packaged with many professional features, including convenient MIDI learn for over 75 parameters, a powerful preset management system, 128 factory presets, and more.

Serge Filter Tour | Serge Modular | Episode 07 | Res EQ, VCF2, Siegfried, VCFS, VCFX, VCFQ

video upload by Cinematic Laboratory

"There are currently 1601 filters on ModularGrid. It may be impossible to pick the right one for your case. If we check out the modular pioneers, we'd see Moog's legendary ladder. Buchla only made a rare triple bandpass, Roland and Korg refined far eastcoast synthesis and there are a few exotics like the Wasp and the Polivoks. In this video I want to focus on the Serge filters (eurorack format) which I rediscovered last year. He has five designs with distinct differences. There's the RES EQ fixed filter bank, the VCF2 variable bandwidth with no resonance (?), the VCFS with a variable slope (?) and the highly appreciated VCFQ with variable resonance. A few weeks ago Serge released the VCFX with a 'new gate' on a single panel. It's a simple utility filter on its own, but combined with the gate we'll have a patch programmable LPG. Or a bandpass gate.

I'll be using the Schlappi THREE-BODY as a triple sawtooth voice making a chord. It's a big and nasty sound that could use a filter. It inevitably turned out to be a long video because I had the pleasure to go through five different filters. I tried to keep it fresh and entertaining. Who doesn't love playing the cut-off :)."

Logan String Orchestra

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

via this listing

"A perfect working Logan String Orchestra, the lush string synthesizer released by the Italian company Logan in 1973. The machine has been recently checked and calibrated by a professional technician, it works like a charm.

Released in 1973, the String Orchestra expanded Logan's range of string synthesizers by offering warmer and more refined sounds. It positioned itself as an alternative to the edgier character of the String Melody I, also produced by Logan, as well as to later string synthesizers like the Solina String Ensemble. The String Orchestra is a fully polyphonic synthesizer featuring three parallel BBD (Bucket Brigade Device) chorus circuits and a unique architecture that makes this machine truly one of a kind.

The Panel
The Logan String Orchestra features five mixable string sounds, each with its own dedicated volume slider. Interestingly, these sliders are duplicated on the front panel, with one set assigned to the first two octaves and the other set assigned to the remaining two octaves on the right. When both sets of sliders are adjusted identically, the same sound is produced across the entire keyboard. However, by setting them differently, you can perform with two distinct sounds simultaneously on the left and right sides. The small panel near the keyboard features the following controls:

Bass: Volume slider for the bass sound, assigned to the left side of the keyboard
Perc: Adjust this slider to make the bass sound punchier
Tone: Functions like the "Brilliance" slider found on many vintage string machines, shaping the brightness of the sound
Slalom: Acts as a pitch bend control, also useful for fine-tuning the main patch
Volume: Master volume slider for the overall output
Hawaii: A piezo tactile switch that temporarily applies a pitch envelope to the notes being played
Orchestra : when this button is ON, the synth deactivates Violins and Bass
The Sound

The overall sound of the String Orchestra is silky, warm, and extremely pleasant—quite similar to the string sounds of the marvelous Godwin Symphony 849. It’s rich and velvety in the midrange, while remaining precise and never harsh in the higher octaves. This makes it quite different from the grittier, wilder sound of the popular String Melody, also produced by Logan.

The Cello, Viola, and Violin sounds represent three different octaves of the same oscillator: a beautiful, smooth, and highly musical sawtooth waveform. When used individually, these three sounds create a peaceful and smooth string tone, where you can truly appreciate the lush effect of the three parallel BBD choruses in action.

The two Orchestra sounds are based on a rectangular waveform. They share the same fundamental frequency but differ in pulse width and filtering. Orchestra I features a very narrow pulse width, a 12 dB/oct low-pass filter fixed at 10 kHz, and a low-frequency cutoff that doesn’t go below 180 Hz—perfect for adding extra harmonics to the patch. Orchestra II has a wider pulse width, a 6 dB/oct low-pass filter with mild resonance, adding warmth and body to the patches.

And finally, the Bass sound. This is a very fat, filtered sawtooth waveform ranging from C0 to A1. The Perc slider adds a gummy sine waveform with a fast attack and a gently quick decay. By lowering all the sliders on the right side, it’s possible to play the Bass sound on its own."

Modulation 'Masterclass'

video upload by Cinematic Laboratory

"First of all, I put 'masterclass' between quotes because I am not a master. I can call myself an 'expert' after +10.000 hours of patching but that's no guarantee for good information. However, you wouldn't be interested in watching modulation basics either. So my 'masterclasses' are more like sitting around the campfire, telling ghost stories, and we're all equal.

I've been inspired by a subscriber, who pointed to his beloved Rossum Trident/Triton as his/her/their favorite VCO. I looked it up, decided there's too much overlap with my THREE-BODY VCO, but noticed something interesting called 'Zing modulation'. It's a recipe based on ring modulation, with the simple trick of syncing the carrier and modulator. Dave wrote he may have been the first person who ever used the term 'hard-sync', but credited the technology to Serge Tcherepnin. Suddenly I was lost and inspired in a new world of modulation I did not know about. Since it's a recipe instead of a circuit, we can all use it as long as your VCO has a Sync input, and you have a ringmod in your case. If you don't, get one. It's an essential piece and it costs nothing.

I can't explain Zing modulation (ZM) without Ring modulation (RM) without thru-zero amplitude modulation (AM) and when the bloody TZ comes along I am aways reminded that I am still clueless about thru-zero FM. I've seen good, bad and no explanations about TZFM. I know it preserves pitch, it's been restricted to digital - but now it's also possible with analog - and it needs to be supported by the VCO. You can't seem to patch it up, the VCO should do it. I have a problem with things that can't be done. It's not that I am stubborn, an important aspect of creativitiy is to never give up. And to be confident you'll figure it out eventually. Thanks to Dave Rossum's recipe, I wondered if I could ringmod my modulator VCO before it goes to my principal VCO's LIN-FM. It can't possibly be amplitude modulation anymore.
I experimented with ring-modulating the modulator with an inverted version of itself, so it would flip polarity and go thru-zero. I don't know if this qualifies as true thru-zero so I call it WTFM.

Anyway, this video can keep you busy for weeks. Happy Patching!
Robert.
