The Tappan Zee (Gov. Mario M. Cuomo) Bridge - I-87, I-287, and NYS Thruway

video upload by CatSynth TV

"A ride along I-287, I-87 and the New York State Thruway westbound in Westchester and Rockland Counties, just north of New York City. Along the way we cross over the Hudson River on the Tappan Zee Bridge, also known as the Gov. Mario M. Cuomo Bridge. The original Tappan Zee Bridge open in 1955 - it was only designed for a life span of 50 years, and was showing signs of decay by the 2000s. It was replaced in 2017 by the new twin cable-stayed span that we see in this video.

Filmed in October 2023, with pockets of fall foliage colors visible.

10-07-23 Live Ambient Modular Synthesizer performance

video upload by david rothbaum

"The main instrument here is the Assimil8or. I sampled harmonics on my Fender Bass VI for a project with @jonat8han a little while back then yesterday I created a simplified version of that instrument on the Assimil8or using the new midi expander to make it polyphonic.

Sequencing - @squarpinstruments Hermod +
Delay - @intellijel Sealegs
Bass - Atlantis
Mixed with heavy use of the internal limiter - @noiseeng Xer Mixa

Thanks for listening."

Moog Matriarch and Rossum Eurorack Ambient Ghost Horns

video upload by riotbell

"This is an attempt to pair the Matriarch with some Eurorack. The Matriarch is being filtered through the Rossum Morpheus filter which is in turn being modulated by the Mob of Emus.

The patch on the Matriarch is totally standard triangle patch (nothing special).

Trying to get back into recording and uploading some more Matriarch related videos.

Thanks for listening."

NAMM 2023 - Dave Rossum - Sound Semiconductor

video upload by sonicstate

"At NAMM 2023, Sonic State caught up with Dave Rossum, the founder of Sound Semiconductor, to discuss the company's exciting developments. Sound Semiconductor is a development from SSM, a company that designed synthesizer chips for the first Prophets in the early 1970s. SSM went on to produce chips for professional audio and was later acquired by Analog Devices. In 2016, Rossum, along with Marco Alpert and a little bit of seed capital from Universal Audio, started Rossum Electro Music. At NAMM, they met Dan Parks, who used to run SSM, and talked about the idea of resurrecting the classic SSM chips. Six months later, they started Sound Semiconductor, which includes some resurrections of the classic SSM chips and some new ideas.

Rossum explained that the analog chips give instruments their own unique character, which digital processing cannot achieve. Analog chips have variations from unit to unit, and the designer's job is to make those variations as small as possible while allowing those variations to give instruments their own individual character. Analog distortions are also natural, making them more appealing to the ears than digital algorithms that give aliasing, and Dave told us he finds designing analog chips to be more artistic and enjoyable than designing digital ones."

Patching Sound: Understanding modular synthesis

video upload by moogfoundation

"Want to get hands-on with a modular synth? This Moogseum exhibit, new in summer 2022, lets people patch in -- and explore what it's like to play and perform on a modular synthesizer.

Sound designer Reek Havok, who created the custom, interactive exhibit, talks about how Patching Sound fulfills the Bob Moog Foundation's goals of sharing the history behind modular synthesis, and the technology within the modules -- both in a way that's accessible to all ages and all of our visitors.

Exhibit funded in part by synth pioneer Dave Rossum of E-mu Systems.

Thank you North Carolina Humanities for awarding us a grant for Patching Sound!

Dave Rossum on audio Companding a SynthSummitShow special

video upload by Ken Flux Pierce Fluxwithit

"The SynthSummitShow is series of interviews with the people behind the music tech gear we love. This special episode was not intended to be a typical SynthSummitShow episode. Dave Rossum is a long time pioneer of the audio industry. Please check out the previous SynthSummitShow episode 8 [below] for a more direct interview. you can also catch the last interview we did with him on the BEATPPL episode 70. [posted here]

This conversation stems from me trying to better understand audio companding as was used in E-MU's early samplers. diving into wikipedia and other online resources, I found inadequate. Most of these online resources just assumed that the companding was the same as done in early days of telecom. This however I found to be inaccurate. So I reached out to Dave to ask him some details and what follows is the result. I can't thank Dave Rossum enough for sharing his knowledge and time with not just myself , but the community as a whole. This industry would not be the same without him and I am humbled everytime I get to speak with him."

Rossum SP-1200 Now in Production

This one was spotted and sent in via Soviet Space Child.

via @rossumelectro "SP-1200 reissue units are in production!

How many Easter eggs can you spot on these circuit boards?

A continuation of Dave’s fifty-year tradition of instruments made to last, the Rossum SP-1200 reissue is expertly engineered by its original designer for decades of reliability and is built locally in the United States. Assembling and testing the instruments in close proximity to Rossum’s California headquarters allows for SP-1200’s sonic character to be delivered according to the most exacting quality standards.

On the rear of the main circuit board, users will find dedicated, balanced jacks for all filtered and unfiltered channel outputs as well as the mix output and a new sample input monitor feature.

Throughout the process of creating the SP-1200 reissue, Dave was delighted that with very few exceptions, authentic components exactly the same as those found in the vintage classic instrument could be used throughout and took great care to maintain the classic SP-12 and SP-1200 circuit board layouts. Inside and out, SP-1200 is faithful to the original operation and preserves the coveted, authentic sound and character of the classic vintage instrument. Through this labor of love, Dave was able to create an instrument that should sound exactly the same even to the most discerning ears."

New Rossum SP-1200 Officially Announced at $3,999.00

"Why did you take this approach with the SP-1200 reissue?" video upload by Rossum Electro-Music

"What are some challenges working with vintage digital technology vs vintage analog designs?" video upload by

via Rossum:

"This is a pre-order for the second lot of SP-1200 reissue units. We fully expect to be able ship the units from the second lot by the end of January 2022. Your payment method will be charged immediately. Limit 2 per customer.

The latest in the SP-12™ family, the Rossum SP-1200® is an authentic reissue of the iconic classic SP-1200 sampling percussion system. Building on the engineering of 2020’s 35th Anniversary SP-1200 Renovation, including study and analysis of many vintage units using modern technology not available during SP-1200’s original production run, the team determined that virtually all original components ought to be used in order to deliver the sound at the very highest standard of precision. E-mu Systems co-founder and original SP-12 and SP-1200 designer Dave Rossum has duplicated the original analog and digital electronics of the landmark 12-bit drum machine sampler as closely as is possible thirty-five years after its debut. Throughout the process of creating the SP-1200 reissue, Dave was delighted that with very few exceptions, authentic components exactly the same as those found in the vintage classic instrument could be used throughout and took great care to maintain the classic SP-12 and SP-1200 circuit board layouts. Inside and out, SP-1200 is faithful to the original operation and preserves the coveted, authentic sound and character of the classic vintage instrument. Through this labor of love, Dave was able to create an instrument that should sound exactly the same even to the most discerning ears.

Changes and enhancements were made where they were compatible with the original design, without compromising the classic vintage sound. Sampling memory has been expanded to the maximum capability of the original sound engine. An all-new memory card storage solution with new functions seamlessly integrated into the operating system allows musicians to conveniently save, rename, and delete files and folders, and supports importing vintage SP-1200 disk images packaged in the popular .HFE format. Also included in every box, a 3.5” “floppy” disk 💾 containing modified software for original vintage SP-1200 units adds a new Set-up Special function allowing users to transfer all sounds and sequences from an original SP-1200 to the Rossum SP-1200 reissue over a standard MIDI cable. Whether using 3.5” disks or the popular floppy drive emulator modification, users of classic SP-1200 units are able to recall and remix their work on the SP-1200 reissue.

The Ladder Filter Has Evolved - Evolution by Rossum

video upload by Patchwerks Seattle

"In this video resident expert Matthew Piecora (aka EZBOT) shares in an in-depth presentation on the Rossum Evoltion: Dave Rossum's take on the classic ladder filter.

At the core of the EVOLUTION Variable Character Ladder Filter is Dave Rossum’s enhancement of the iconic Moog ladder filter from the original E-mu Systems 2100 LPF module (which, incidentally, Dave counts as his favorite sounding of all of the analog filters he designed).

For EVOLUTION, Dave has designed new capabilities that not only allow you to dial in all of the outstanding qualities of the original 2100, but combine to let you create the sonic characteristics of a wide variety of other filter types.

“Rossum Panharmonium - Internal Sounds” by Friendly Noise

video upload by Friendly Noise

"The Panharmonium is an audio processor, but also a sound source of its own. It can store up to 12 presets (the settings at a certain moment) and 12 different spectra of the sounds being analized. Combining presets and spectra, the Panharmonium can produce a great number of sounds right out of the box.

Everything you hear in the video comes from the included factory presets and spectra. There are no filters and no VCAs in the patch, so the sound is drone-ish.

Modules in the patch: Rossum Panharmonium, Intellijel Quadrax, Xaoc Tallin. Reverb comes from the Strymon Nightsky.

“Rossum Panharmonium - First Contact” by Friendly Noise

video upload by Friendly Noise

"This is my first patch with the strange and amazing Rossum Panharmonium, a 'Mutating Spectral Resynthesizer', as it reads on the unit. Resynthesizers are an extremely rare kind of modules/instruments. The approach of Rossum Electro Music is easy to use and gets you immediate results.

In the clip, a full song is processed two times with different settings. The mix is 100% wet: you are always listening to the sound after processsing with Panharmonium.

Modules in the patch: Rossum Panharmonium, Qu-bit Nebulae V2, Intellijel Quadrax, Xaoc Tallin. Reverb comes from the Strymon Nightsky.
