"Time for a new video and it was about time for me to do something radically different. So here it is, out of pure joy about making music. No deep meanings behind it just experimental joy. And yes i loved the boys noize sample so much that i had to use it ;)

Enjoy Life and enjoy making music :)

Cheers"

Grove Audio PM Resonator

via JohnLRice

via Grove Audio:
"The PM Resonator is a recreation of the formant filter section of a Polymoog™ synthesizer in a standard 5U double-width modular panel. Each of the three filter channels has a control for frequency, signal gain, and emphasis or resonance.

A rotary switch selects the type of filter mode for each of the three channels. The modes are low pass, bandpass, band notch, and high pass."

9090 Roland TR-909 DIY Rack Clone

via this auction
"An Electronics Project With A Difference. Build Your Own tr-909!

If you've ever wished for the warmth and flexibility of an original analogue drum machine like the TR-909 and you're also handy with a soldering iron, then a real alternative could be to put one together yourself. The 9090 project starter kit contains what you need to get started. This is a project suited for more experienced electronics enthusiasts and requires a small number of obsolete components.

The 9090 Project is an authentic sounding, rack-mounted, MIDI controlled copy of the TR-909, that you build yourself. The starter kit being offered for sale in this listing contains the bare printed circuit boards and a small number of special components. The majority of the electronic components are to be obtained separately from your own preferred electronic components supplier.

The advantage of using these boards is that the hard work has already been done: well thought-out, compact and extensively tested board layout design makes them an absolute pleasure to build, and the end result looks fantastic. These PCBs contain zero errors, therefore fitting all of the components and doing all of the wiring correctly can often result in something that works pretty much straight away..."

Descriptions for the following six circuit board pics in order:

One: "Board One - Contains power circuit, noise sources, bass drum, snare, low and mid-toms"

Two "This image shows all of the parts you get together: Three PCBs, PIC microcontroller and three PROMs"

Three: "Board Two - Contains power circuit, noise sources, bass drum, snare, low and mid-toms"

Four: "Four chips supplied: PIC Microcontroller contains embedded software for the MIDI interface, and three PROMs contain data for the hi-hats and cymbal sounds."

Five: "Board Three - Output sockets / audio mixer"

Six: "High quality silkscreen makes assembly easy."

"Features

□ Includes all analogue sound circuits from the original machine, and it sounds identical. Even better, in fact - because some of the sounds have more flexibility. The Bass Drum, for example, has a number of new additional control knobs that enable it to make a fantastic range of kicks. Take a listen to the Sound Samples on the right (mp3 format).

□ It does not have a sequencer of any form, but it has an excellent full MIDI interface. The PIC microcontroller that comes supplied with the boards is pre-programmed with embedded software that forms the heart of the MIDI interface (decodes the MIDI messages and translates them to trigger and velocity signals for each drum circuit). The drum sounds are velocity sensitive. How the drum sounds are mapped across the keyboard scale can be reconfigured via System Exclusive messages. LED indicates MIDI activity.

□ A 'bonus feature' is a Sync24 output, which enables you to sync something like a TB303 or MC202 to the MIDI clock via the 9090.

□ The boards are intended to be built into a 19” rack enclosure or a sloping-top box (or whatever you choose) to form a MIDI controlled 909 clone. It's entirely your call on what shape and size yours is going to be! You can also choose to only build some of the drum circuits if you don't need all of the drum sounds.

I kept most of the sound circuits pretty much as they were in their original form, and the project includes all of the sounds found on the original machine. Some of the sounds have been enhanced to expand their capability far beyond those in the original machine, the Bass Drum being a good example: it now has seven potentiometers instead of four, and sounds absolutely awesome. I think many people built their 9090s just for this sound alone. Some original components that have become long obsolete have been replaced by easily obtainable substitutes, without affecting the timbre of the drum sound in any way.

All of the sound circuits are built onto the two main large boards that are seen in the picture. The third long, narrow board is used to mount the rear output sockets onto (featuring individual and stereo summary outputs). I used two main boards instead of one because it means that you can stack the two boards if you want to build the project into a relatively small enclosure, and they’re just easier to work with. The boards also contain the MIDI interface, output mix amplifier, power regulation circuitry and even a handy DIN Sync output so that you can use the 9090 to synchronise your TB303 or MC202 to MIDI clock. The completed boards just need potentiometers and output sockets wired to them, power supply and MIDI input, and away you go – a fantastic analogue drum machine you built yourself."

1979 Roland VP-330 Vocoder

via this auction

"The VP-330 combines those famous ethereal Roland strings, haunting preset male and female choirs, and a truly phenomenal analog vocoder with a lush Dimension-D type stereo analog chorus that results in a sound palette unmatched by any other unit before or since.

Roland manufactured the VP-330 for only one year (between '79 and '80) and as a result these instruments are ridiculously rare, especially in fully working and beautiful cosmetic condition. Two different versions of this machine were made, the Mark I featuring organ-style rocker switches and a SAD512 IC-based chorus circuit, and a Mark II (this unit here) that had TR-808 / Jupiter-8 style buttons and MN300X IC-based chorus. I have played both versions side by side and can honestly say that whatever slight sonic difference I heard from the different chorus circuits was like comparing two Minimoogs or two TB-303s...in other words, nothing that couldn't just be the result of 30 year old electronics drifting in calibration. The two VP versions sound identical enough that blindfolded you wouldn't say one was better or worse."

Electronic Muisc Laboratories EML-500

via this auction
"The circuit design and componenets used were very different from what most of the other companies were doing. If you want something truely different sounding, this is it. It might have a generic appearance similar to that of the Arp Odyssey or Octave Cat but believe me, this sound nothing similar to either of those. EML synths are probably best described as 60's sci-fi movie meets science lab sounding. I recorded a couple of clips of this synth with the envelope repeat on (droning). It can do a lot more than these clips, I just already had these recorded.

Eml2 by Rodman Serling

In addition to the individual circuits sounding very unique (oscillators, Filter, VCA) it is a very feature-rich synth and include many unique features. It has microtonal tuning so you can tune it to a different scale. The sample+hold circuit is very unique and doesn't sound like any other I've heard. It has 2 oscillators and noise/input. I love overdriving it by running one of the outputs back into the input (as you can see in the pictures), but you can run your voice, a drum machine or whatever through the input and process it through the pre-amp/filter/ring-amplitude mod/VCA. I envelope can self trigger for drones. Did I mention the ring mod circuit will also do amplitude modulation? You can route the sample+hold and LFO to multiple desitnations concurrently. The filter is a multi-mode meaning it will do standard low pass as well as high pass and band pass. The filter is also very unique sounding."
