OPERA ROTAS Firmware Update - Poly ROTAS Jam Demo - Spherical Sound Society

video upload by SPHERICAL SOUND SOCIETY

"Opera Rotas has a new firmware that transforms the drum machine into a fully 9 voice polyphonic synth based on true, vintage Yamaha FM chips.

It´s a bit like transforming a Sega Genesis/Megadrive into a playable synth with a midi keyboard.

If you have an Opera Rotas (revision 0.9 or higher) you just need the new firmware, available in my stores. So you can have both firmwares with one machine: the classical Drum Machine and this new PolyRotas."

"OPERA ROTAS jamming, with PO-32 and processed with ableton.

Im thinking in expand the OR firmware, so I started playing it and this came up

SPHERICAL SOUND SOCIETY Introduces OMNICYCLONE - A Generative FM Beat Machine

Launching OMNICYCLONE. A Generative FM Beat Machine video upload by SPHERICAL SOUND SOCIETY

"OMNICYCLONE is a unique take on generative synthesizers. It's primarily focused on percussive phrases, but it can also create melodic content.

At its core lies a Yamaha OPL2 emulator that has been extensively modified to achieve things the original chips couldn't – like a fully stereo image and a complete revamp of sonic possibilities.

We've taken some of the most interesting features from WINTERMUTE, expanded the emulator further, and hybridized them with OPERA ROTAS features to birth a new generative beast that sounds surprisingly retro and modern at the same time.

"OMNICYCLONE is a unique take on generative synthesizers. It's primarily focused on percussive phrases, but it can also create melodic content.

At its core lies an OPL2 emulator that has been extensively modified to achieve things the original Yamaha chips couldn't – like a fully stereo image. Some Yamaha chips of that era only offered hard-panned stereo (just center, left, or right). OMNICYCLONE provides 256 possible stereo positions, which sounds probably awesome.

We've taken some of the most interesting features from WINTERMUTE, expanded the emulator further, and hybridized them with OPERA ROTAS features to birth a new generative beast that sounds surprisingly retro and modern at the same time.

In this new incarnation, we've added volume bars for each channel, providing a clearer visual understanding of what's happening under the hood.

The synth is controlled by 2 banks of parameters, plus a fully-featured global LFO and global parameters for controlling each of the ADSR stages. It also includes a variety of new generative strategies that are explained in the manual.

OMNICYCLONE runs on the Fluorine hardware, meaning you can flash Fluorine's other firmwares (there are 4 different ones to choose from) in addition to the OMNICYCLONE firmware. This gives you multiple synths in one piece of hardware.

There's also a new firmware that turns the Fluorine hardware into a USB MIDI Controller with 2 banks of potentiometers. This means you essentially have multiple synths plus a MIDI controller in one device

The OMNICYCLONE firmware is closed source. Existing Fluorine users can order the digital files to easily switch between their other Fluorine firmwares and the OMNICYCLONE firmware. The USB MIDI Controller firmware is also free for Fluorine users, but the OMNICYCLONE firmware has a small fee to support its development.

Spherical Sound Society - Opera Rotas Experimental FM Drum Machine

"First demo of the machine. Please excuse the poor direct audio. I will be uploading quality captures to soundcloud in the coming days.

Live it sounds crisp, crystal clear aun unique beyond words.

I have written an experiemtal synth/drummachine around the Megadrive FM audio chip. The firmware is in progress. The machine creates patters at the fly that you can mangle and tweak with mostly all the FM parameters in real time.

Its plenty of beautiful electronic landscapes, rythms and techno mayhem.

The unit has a midi in port, so you can play it with a keyboard too (this firmware is to be implemented, if any)

Some units and PCBs will be available to sell in the coming weeks at my tindie store:

https://www.tindie.com/stores/jc2046/"

"OPERA ROTAS is a mutant, generative drum machine. It's built around a Yamaha OPL2 FM audio chip, a close cousin of the Sega Genesis / Megadrive consoles.

At the core, it has a real Yamaha OPL2 audio chip and live sounds bonkers. Brutal, it's all body weight while being crystal clear and punchy. Really the videos don't do aural justice but it serves to get an idea. There will be decent audio demos coming to my Soundcloud soon.

The firmware is a work in progress. One branch of the firmware consists of attaching a midi keyboard to it and converting it into a fully fledged polyphonic synth.

The project will go open source at some point. I just ask for people to not do commercial PCBs of it, as I sell it here. If you get one PCB or kit you can ask for the source code to tweak it if you will.

It comes in 4 flavours:

Built unit. Ready to plug and play.
Full kit. Everything you need to build one. You need to solder it. Beginners level.
Basic kit. The PCB plus a programmed SMT32 microcontroller. You source the rest of the components.
PCB alone. You source all the components, program the chip, and run it."

Spherical Sound Society ARCANE: Generative Chiptune FM Drum Synth

video by ZElTGElST

Spherical Sound Society brought us the Opera Rotas Experimental FM Drum Machine posted here.

"ARCANE is a generative synth that lies somewhere between a synth, a sequencer and a drum machine, depending on how you interact with it.

It is based on an authentic Yamaha YM2413 FM chip; the one used in some arcade coin ops, MSX and in the japanese version of the Sega Master System.

To control it it has 6 potentiometers and 3 buttons. The pots are:

-Tempo. It controls the tempo/speed

-Base Register. It determines if the machine is more musical or glichy

-Intensity. The higher this pot, the more amount of notes and percusions sounding. This is a veru playable way of alter the generative composition by transitioning between the simple and complex sound explorations

-Sequence. It let you browse between sequences.

-Dispersion. the higher this pot, the most registers that we are writing on the chip, so the sequences get more complex and chaotic

-Combination. It multiplex, demultiplex and recombines sequences, keeping the output related but always fresh and different

It has 3 buttons, Left, Right and Reset. Reset is located in the arduino and is self explanatory. Left and Right buttons are to be determined as the firmware is still in development.

It has Clock In and Clock Out so you can synch it with external gear

It comes fully assembled and ready to play.
