Synthesizing waveforms with a frequency divider - a sequel
video upload by organfairy
"I show how it sounds at 4:17 and play it with a keyboard at 5:50
Winter is getting closer so this is the time of year when I start building things. The first of my projects is a revisit to an old idea of synthesizing waveforms with a frequency divider. This time the waveform in question is a sine wave and some other waveforms derived from it.
The old idea is here: • Synthesizing waveforms with a frequency di... [below]
The project is quite a bit more complicated than the previous 'digital' waveform synthesizer as the sine wave is very..... well....wavy, as there are no straight lines like there is in the triangle and sawtooth waves. Therefore I had to take a different approach using a couple of 74LS138 3-8 decoders and an awfull lot of resistors.
The music is my attempt at playing something relaxing on my Wersi Prisma DX-5 organ."
Synthesizing waveforms with a frequency divider
video upload 8 years ago by organfairy
"The demo starts at 4:15.
The normal approach to generating waveforms is to start with a sawtooth wave and then fold it into a triangle wave and schmitt trigger it into a square wave. But it is also possible to synthesize the waveforms by means of a frequency divider and some logic gates. Off course the generated waveforms will be somewhat 'edgy' but that can probably be filtered out and some people might even find it usefull.
The music is something I made back in 2005 on the homemade synthesizers I had then. It's not the best piece I have made but I am still willing to take responsability for it :-)"

This is the 1U,60HP + 3U,4HP version of Drummertime. Created to fit in smaller cases, like this 62HP Palette case.

ODD-1 Overview: 03 Envelopes & Time Path
video upload by oddment
"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."

New BEHRINGER BQ-10: It Will Leave You Speechless!
video upload by Behringer
"The Behringer BQ-10 is a 24-step analog sequencer that captures the essence of classic sequencing with the flexibility of modern modular workflow. Designed in Eurorack format, it’s hands-on, immediate, and built to spark ideas without screens or menus getting in the way.
Key features:
• Single 16-step or dual 8-step sequences
• Dedicated 8-step CV channel for filter or amplitude control
• Per-step trigger outputs for custom reset patterns
• External trigger input for clock sync
• Full CV control for deep modular integration
From evolving sequences to tight, synced pattern changes, the BQ-10 brings vintage character and real-time control straight into your setup.
Available now through Behringer distributors worldwide."
First Stage Fright
video upload by davidryle
"Rossum Electro-Music works its' way into the 5U system. The results are pretty nice.
Using a Trident Oscillator with quantized pitch CV from a Mob Of Emus into three envelopes from Synthetic Sound Labs Octal VCA Expander, then on to the Rossum Panharmonium Mutating Spectral Resynthesizer.
A tap off the Trident is sent to the Rossum Linnaeus filter for a percussive FM part which starts the work. The timing is from the Moon Modular 563 Trigger Sequencer.
The rhythm section is the Synthetic Sound Labs / Hagiwo Geo Gruvn euclidean sequencer for all the parts.
The bass part is the SSL Woven Spirits (MI Plaits) in wavetable mode.
The dual Q960 sequencers are transposing the 1V/Oct input to the Panharmonium and sending various control voltages to the bass and another pad swell sounds from the 5U system.
All recordings are in real time to Cubase 12 and video is edited in Final Cut Pro."

Solar Sound Card - ear modular
video upload by Sonic Seed
"A light-sensitive, portable sound generator that extends Ear Modular beyond Eurorack.
Its circuitry responds to ambient light, transforming sunlight, shadows, or small light sources into dynamic sonic textures.
Built for direct interaction with the environment, it invites musicians to listen with their eyes and see with their ears, shaping sound through the shifting presence of light.
Equipped with an integrated speaker and powered by a coin-cell battery, it functions as a self-contained instrument—intimate, mobile, and alive to its surroundings.
Solar Sound Card is a series of light-sensitive sound cards.
Each card reacts to variations in light, transforming brightness and shadow into shifting sound.
Every card includes a built-in speaker, and can also be connected to external speakers via an audio jack.
The audio output provides SP+ (tip) and SP– (ring) signals.
At present, there are seven types of Solar Sound Cards — each with its own character, circuitry, and way of playing.
