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 :-)"

"THE FLORIAN SCHNEIDER COLLECTION

Auction to be held at Musician's Hall of Fame & Museum, Nashville, on November 19

An incredible collection of more than 450 artifacts from the life and career of Florian Schneider, co-founder of the pioneer electronic band Kraftwerk."

Pics and videos featuring some of the gear below, and his Lederhosen for good measure (thanks greg!).

Update: the post has been fully updated with all the synth related gear. This may just well be the longest post to be featured on the site. I wanted to capture all the pics for all of the details including notes, scuffs, and of course serial numbers. It's an interesting look into what he used, the condition he keped his gear, in some cases, how he actually used his gear. Note the phonetics on the keys of the Casio CZ-101 and DX-100. Note the Midi Switch Box with a built-in speaker? What's that about? Note the camouflage key strap on the Korg RK-100 Remote Keyboard. Did he pick it out himself or did the keytar just come with it? Note the repeat midi controllers and the MIDI saxaphones. Wind was his primary instrument. You'll find a ton of the acoustic gear he used in the other listings. This is a fascinating insight into both what and how he used his gear.

Rack Mount Sennheiser VSM-201 Vocoder

Starting Bid $5,000

Estimate $20,000 - $40,000 USD

A late 1970s Sennheiser VSM 201 Vocoder with no serial number from the personal studio and collection of Florian Schneider of Kraftwerk (see images). While it’s said that only a few dozen of these Vocoders were produced, a few examples made it into the hands of forward-thinking musical artists including Herbie Hancock, Daft Punk, and of course, Kraftwerk, who used a VSM-201 like this on their albums Man Machine (1978) and Computerworld (1981). The VSM-201 has an intelligible sound that has not yet been bested by modern gear. Includes power cable. This VSM-201 has been removed from its wooden enclosure (which bears the serial number plate) and modified with a metal rack mount casing, presumably for live use. Requires 240v, IEC power cable not included.

Dimensions: 19 x 9 x 9 inches

Category: Kraftwerk, Equipment

Provenance: PROVENANCE From the Estate of Florian Schneider

Synthesizing with Moog | Lesson 3: Vibrations

video upload by Moog Music

"Sound is a phenomenon of vibrations in the air. In this episode, we look at the source of vibrations on the synthesizer – the oscillator. We investigate how to tune the oscillator to a particular note and how to add oscillators together. We also dive into the topics of harmonics, looking at how the shape of oscillation creates distinct tones with different harmonic characteristics.

Written, hosted, filmed, and produced by our team of electronic musical instrument experts, this new seven-part educational video series makes learning the fundamentals of synthesis accessible, engaging, and inspiring for anyone curious about science, music, and how the two worlds converge. We set out to create a series that brings you as much technical knowledge as it does entertainment and joy as you watch each episode!

We invite you to follow along with us at home with a printable worksheet corresponding to the contents of each weekly episode. https://inmusic.to/bdhnff3m

"My notes unedited:
----Probably cant change----
Lfo mode / pitch decouple on osc 2 would be goated
Mod wheel as a mod source(expression source with nothing in the jack?)
Pitch wheel as a mod source
Lfo 2 as an signable mod source
Gate prob should work on the arp page as well
Maybe note prob as well, but thats mostly covered by arp modes
Ratchets would've been a huge buff to the sequencer

----Probably could change----
F env mod to osc wave is almost a useless range
Velocity curves could use a tweak, maybe that's preference
Any modulation to pitch, (i feel) needs a more generous taper for low amounts
Noise can get way too loud.. Am I crazy?
Pressing 1-16 in note prob should do something clear that note? Deactivate it?"

Synth Spotting : Rabbit Trap - Official Trailer | Starring Dev Patel and Rosy McEwen

video upload by Magnolia Pictures & Magnet Releasing

"In theaters September 12.
http://rabbittrapfilm.com/

Seeking new inspiration and a fresh start, married musicians Daphne (Rosy McEwan) and Darcy (Dev Patel) move to the Welsh countryside to finish their new record. While collecting audio samples, Darcy inadvertently creates a field recording of mysterious sound never before heard by human ears. The discovery renews Daphne’s creative energy, but as the echoes of her music bleed into the surrounding landscape, ancient and malevolent woodland forces are disturbed. One day, a stranger arrives on their doorstep. The couple initially embraces the stranger, who helps them navigate and understand their new environment, but Darcy grows suspicious of his obsession. As jealousy and paranoia infect the makeshift family, the line between reality and myth begins to blur.

Starring Dev Patel, Rosy McEwen, Jade Croot
Directed by Bryn Chainey"

Anyone ID the white system that looks like a cross between EMS, Digisound, and Maplin/ETI? I'm guessing DIY.

"Dear synthusiasts,

long time no hear!

First of all, big THANKS to everyone who made it to our KOMAPARTY 2.0 some weeks ago! We had great fun and were happy to hang out with friends and our community <3

 
Big ups Bertolt Meyer, Teslator, Cate Hops with FridaY and Echosisters!

Here's a few snaps for the vibes:

KOMA BOOTH AT SUPERBOOTH

What's all this??? We're excited to share what we've been working on during the Superbooth preparations, including a few mysterious surprises! You will find us at Booth O400 - same as last year. Just walk up the main big stairs and turn left until you see a bunch of nerds in black dungarees playing weird looking instruments… Probably our best SB drip yet!

This year, we will showcase a handful of brand new designs of upcoming modules to be released later this year including Monoplex - a smaller version of the Komplex sequencer, Bürste - a noise burst generator, a Wavefolder, a Dual Envelope and a KOMA VCO!
Sensei and Kassiopeia, which are both available for pre-order, will also have their space in special installations we’ve prepared especially for this year.

One of them is using your movements or even your heartbeat to generate cool shapes with our new VCO and Sensei sensor modules. You'll be
able to print out the results as a sticker!
