Paul McGowan of PS Audio Explains the Moog Synthesizer

video upload by Paul McGowan, PS Audio

"The classic Moog changed the world. Paul helps us understand what all the wires and modules actually do."

Fascinating bit at 1:50. Paul McGowan actually created his own synthesizer, The Infinitizer. Curious if there are any images of it out there. He almost sold one to Wendy Carlos. It gets a mention in his book 99% True: Almost a National Bestseller which you can find on Amazon here (note this is an affiliate link - see the site's privacy policy for more info).

Update: I asked Paul if he had any pics of The Infinitizer. Unfortantely he didn't, and he no longer has any of the parts, but he did send over the following additional info:

"I don’t have any photos of the Infinitizer, unfortunately. I remember a very sad day back in 1995 or so when I was cleaning out my lab and had to own up to hauling it off to the dump (it was a mere skeleton of PCBs, a keyboard, and lots of wires and didn’t work)."

"The idea was to make 10 synthesizers into one unit that was easy to use. This meant it would be the world’s first polyphonic synth, since musicians only have 10 fingers.

I designed a complete analog chain of 10 modules (the usual: VC filters, oscillators, envelope generators, amplifiers, etc.). Then, I hired an engineer out of Vandenburg Air Force Base who was a whiz at this new thing called “digital”. He designed for me a multiplexed keyboard that constantly scanned all the keys looking for ones that were pressed. The keys were all internally numbered and when pressed, the multiplexer would find an available VC oscillator and assign that number to the oscillator. Because we know the number of the key, the appropriate voltage was sent to that oscillator and it produced the appropriate frequency for that key. In order to have the entire keyboard voltage move up and down (like if you wanted to bend the notes or modulate the frequency with a LF oscillator) the master voltage (that got divided by the individual keys assigned to it) could be accessed as one might normally do through the patch bay.

I also wanted to have the keys pressure sensitive so for that, I invented the use of conductive foam under each key (and that too could manipulate the master voltage to the oscillator banks) and could be assigned to modulate any of the other modifiers too. My patch bay was a switch matrix and pots kind of like ARP used to do.

It was a very cool device which I wrote about extensively in my memoirs, 99% True."

As for the first non organ based poly synth, currently that honor likely goes to one of the following depending how you define it:

1975 - Buchla 502 - six voice polyphonic with minicomputer and ability to save patches to tape drive. Development on the 500 series began in 1969.

1975 - Oberheim FVS - four voice polyphonic with Polyphonic Synthesizer Programmer. Not sure if the 502 or FVS was released first.

1977 - Yamaha - CS50/CS60/CS80 - first single enclosure polyphonic keyboard synthesizers, with the CS80 to be the first synth with poly aftertouch

1978 - Sequential Circuits - microprocessor control the SCI prophet 10 (briefly) and the P-5 --- again based on existing E-mu tech stuff

Morphor Plectrum: Demo and tutorial of analog Karplus-Strong module

video upload by CatSynth TV

"We explore the Plectrum module from Belgium-based Morphor, and demonstrate all of its features. The Plectrum is an all-analog implementation of the Karplus-Strong algorithm for plucked string sounds. It uses a BBD 'bucket bridge' delay, and a one-pole low-pass filter to create the algorithm's all-important feedback loop. In this demo, we introduce the algorithm and show how the different knobs and CV sources affect aspects of the sound. We also try out the advanced 'loop extender' feature that allows us to add other modules into the feedback loop of the Karplus-Strong system.

SEQTRAK and Midicake ARP Inspiring Creative New Ideas

video upload by midicake

"🎹 How do you combine the mechanics of creating melodies with the musical theory that guides and underpins good music, without years of learning and practice? 🎵

🎶Yamaha's Seqtrak is a battery-powered groove box, synthesizer and sampler touted as the Ultimate Music creation station. It has great sounds and some very neat tricks. However, I have 3 big issues, not just with Seqtrak but with step-sequencer groove boxes in general. 🎧

In this video, I'll go through my issues and how to solve them by plugging in a Melody Designer like Midicake ARP. I'll show you how to get more from your Step Sequencer and how powerful sequence generators can inspire new musical ideas with amazing ease.
