JH Triple Chorus Sring Ensemble

via JH on AH:
"many of you have shown interest in my PCB project to emulate the string ensemble effect of Solina, Crumar, and other similar keyboards. I have finished the prototype and have put up some sound samples.

Setup for demos: OB-8 (mostly set to a boring single-oscillator, unmodulated sound) -> JH Triple Chorus / String Ensemble Effect -> Reverb (String Ensemble Effect is sometimes bypassed to show the dry sound.)

Plain and simple string sound (1.1 MB mp3)
I start with a dry sound just to show you how much the Ensemble Effect is altering it, and I switch back to the dry sound towards the end for the same reason.

Enhancing a bell sound (740 kB mp3)
I think the effect is interesting for other sounds than just mere strings, as well.

Chorale sound (equalized ensemble effect) (470 kB mp3)
I wouldn't sell this as a specialized choir effect device, but it's certainly an alternative to the straight Solina-like stuff.
All done with the on-board 3-band Equalizer (which was inspired by the Crumar Performer).

Stereo effect using individual outputs (390 kB mp3)
Yes, we can do Stereo, with the individual outputs.
My first thought was to take the 3 individual outputs and mix them, one panned left, one center, and one right. But then the "Ensemble" effect falls apart, and the modulation sounds overly strong. I think you can do a lot of experiments with mixing the individual outputs, and will find interesting configurations.
The above sound sample was made with a very simple setup, however:
The full mix (main output) goes to one channel, and one individual channel goes to the other. The two channels are then panned almost (but not totally) left and right on the mixing desk.

Playing around with the EQ section (1.5 MB mp3)
Just some aimless turning of the 3 potentiometers in the EQ section, while my OB-8 arpeggiates away. I obviously change the OB-8 sound to something percussive towards the end, and I also adjust the OB-8's filter envelope setting slightly for the percussive sound, but I think it's quite clear what comes from the OB-8 and what comes from the Crumar-like 3-Band EQ.

Adjusting the waveform pot to find the "sweet spot" (790 kB mp3)
What is "the Solina Sound"? I think without any modulation waveform clipping (like the sound sample starts; please also see the discussion of this topic above!), is a tad overly lush for a solina. Or maybe it isn't. During this sound sample, I chance the modulation waveform from no clipping to almost totally clipped and back, and I think the "Solina sound" is where the waveform is just ever so slightly clipped.
This soft clipping (the "waveform" trimpot on the board) is different from a simple attenuation of the modulation CV. It's possible to attenuate (or to
boost) the modulation CV, too, by changing 3 resistors on the board, if you want to make further experiments.

More information, and pictures of the prototype, here.

JUNO-106 TEST PROCEDURE

"'IF' your JUNO-106 has (a) broken VCF/VCA chip(s) or WAVE-GENERATOR chip(s), then this simple test procedure will show you which one(s) it is/are. Other problems with the circuitry around these chips is also possible, but in 95% of all cases, it will be one of them that causes the problems. This test is by no means final. Only an experienced synthesizer technician can perform the necessary tests to check what the exact problem is with you JUNO-106."

Pics of the VieuMikro 2007 event (Toulouse-FRANCE)

stamba put up a few shots on the Matrixsynth forum.

Pictured here is the MOOG Song Producer. There are also shots of his C64 and SX64 based setup.

BTW, stamba mentioned there hasn't been much traffic on the forum in another post. He is right. The forum is there for you to use, so, please feel free to use it. If you have any suggestions for new categories or other, feel free to put up a post in the Everything Synth section.

Update via Stamba on the Matrixsynth forum post:
"Yes the C64c looks like the C128.. and btw the C128 is quite the same size as an Amiga500

Some audio examples :

http://stamba.free.fr/c64/Stamba_-_p64_REC0069.mp3

In these 2 mp3s.. bassline is 100% c64 with any external effect."

Oberheim Matrix-12 Modded

images via this auction. Spotted by Chris.
"This is a classic Oberheim synthesizer! It belonged to a professional musician and powers on. It has been modified for pressure sensitivity and separate audio out."
Anyone know what the pressure sensitivity mod might be? The audio outs I'm guess are the individual outs for each voice on one of the side panels of the Matrix-12 although there aren't any shots in the set.

MOOG Meets Taco Bell and Goes to Church


I'm currently reading "Analog Days" by Trevor Pinch and Frank Trocco. You can find the book in the Synth Books section on the right of this site. I just got to the part were the Minimoog Model D finally came into fruition in 1970. According to the book, it was first introduced to music stores by David VanKoevering. David was putting on a show with a theremin when he first met Bob Moog. Bob went to his show and invited him to come see Gershon Kingsley perform at Carnegie Hall with the MOOG modular. Soon after, David ended up picking up a MOOG Model 10 according to this site. What was particularly interesting was how David first began to promote MOOG.

"Like a traveling medicine show, Van Koevering moved thousands of Minimoogs by using innovative marketing techniques. In Florida, he hooked up with Taco Bell, handing out free coupons to the restaurant, and then showing up later in the evening to play to diners. He promoted the "Island of Electronicus," an artificial land mass connected by a causeway to the Florida coast, where a Moog concert was scheduled. The radio ads announced, 'Where is the Moog synthesizer? It's here now ... to stimulate your feelings, thought, and your love for your fellow man.'"

Yes, this Taco Bell. :)

The above quote comes from this article from the San Antonio Current. BTW, I couldn't find an image of the Taco Bell flyer although there is one pictured in Analog Days. If anyone knows where I can find one online, feel free to comment. The image in this post is of David's "The Island of Electronics" which he formed shortly after. You can also read more about this on VOTAGE::MAIN where I found the image. Be sure to check out all the links in this post for more of the fascinating story and of course "Analog Days."

David later repackaged the Memorymoog as the "Sanctuary Synthesizer" and sold them to a number of churches. I wonder how many are still sitting in storage... (image via this post)

Note: according to some on AH and other sites there are inaccuracies in the book, "Analog Days." I haven't discovered a comprehensive list. If you know of such a list, please comment. If you know of the inaccuracies also feel free to comment. If there is enough interest I could create the list with a sticky post for us. Regardless, the book is a great read. It is well written and a fascinating story of the birth of MOOG, and it touches on Buchla.

demo track featuring:
"the Banalogue VCS being used as a filter. It's most apparent after the break. The "break" was me unplugging the mixer (Doepfer A-135 VCMIX) that had the drum sounds and the VCS running into it, flipping the cycle switch on the VCS, turning the cv on the VCS' mixer channel down, turning the gain up and plugging the mixer back in."

Roland CMU-800R

via this auction
"The following is from a Roland data sheet from 1983: **** The CMU-800R is a new dimension computer peripheral which allows free composing and arranging, as well as automatic performance. This unit features a host of functions, real musical instrument sound from its build-in sound source, and a wide variety of musical nuances such as slur, staccato, accent, and legato, plus an added function to control eight external synthesisers. Its is not an extention of a simple hobby computer as represented by conventional games. The CMU-800R is the very first unit to proclaim the arrival of a real computer age in the musical genre. Each computer is provided with a software package for easier programming and advanced editing functions. Now, music fans with no particular knowledge of computers or computer operators who cannot play a musical instrument can both compose and arrange at their option as well as enjoy automatic playback. **** The CMU-800R delivers its maximum performance with its separately available software package. With this software package, anybody will be able to handle the CMU-800R efficiently. The software package includes the CMU-800R control function and edit function for music data preparation. The edit function allows you to do difficult types of screen editing on the CRT monitor connected to the computer. So, sequence editing and modification can be done in amazingly short time. **** Complete built-in sound source for a real music sound **** In addition to melody, bass and chord (4 notes), the CMU-800R has seven percussion instruments sounds, i.e. bass drum, snare drum, low tam, high tam, cymbal and open/closed hi-hats for rhythm patterns. All other sounds have decay and sustain (melody only) effects. In addition, each part can be level-mixed with a slider volume control, and playback tempo can be varied as you desire. The CMU-800R is a product of Roland DG, an electronic musical instrument manufacturer, and built to give a new dimension in sound creation. **** Expandibility, a more sophisticated music system **** The CMU-800R needs an amp and speaker to produce sound. In combination with an effect unit, mixer, tape deck or the like, a more complete sound is created. The CMU-800R is able to operate up to eight external synthesiers simultaneously with its CV & gate outputs. Clock In/Out permit synchronous performance with external rhythm machines and percusion synthesisers. The more-you-play-the more-fun-you-have CMU-800R is superbly expandible into a more sophisticated computer music systems."

Waldorf MiniWorks 4Pole Filter


via this auction

"Without doubt, no other synthesizer component has such a decisive effect on sound quality as does the filter. All of us at Waldorf, and of course the owners of Pulse's and Pulse Plus', know all about the exceptional qualities of our analog filters. We would obviously like all musicians to have the chance to access this quality component, so we simply implemented it as a separate module. The 4-pole is our four pole cascade filter, combined with incredibly fast envelopes and a stereophonic amplifier stage. You are free to apply this filter to any audio signal that you manage to patch into the device via a 1/4" jack. So if your favourite sampler or sample player lacks that special quality, you can give it a sonic boost via the 4-pole. You can even overdrive the audio input to get distorted signals, if you like. Cutoff Frequency, Resonance, Volume and Pan may be modulated by numerous modulation sources, eg. LFO, envelopes, MIDI or the built-in envelope follower.


Technical Features:
Waldorf 24 dB lowpass filter with variable resonance up to self-oscillation
40 programs, divided into 20 ROM presets and 20 user programs
24dB analogue low pass filter with resonance up to self-oscillation
Filter input can be overdriven
stereophonic VCA with real-time panning modulation
VCF ADSR envelope
VCA ADSR envelope
LFO (5 different waveforms; tri, sin, saw, pulse, sample&hold)
15 modulation sources
Envelope follower
4 edit knobs
1 gain knob
1 trigger level knob
5 buttons
Large 3 x 7 segment LED display
monophonic audio input
seperate trigger input
stereophonic audio output pair
MIDI In/Out/Thru
Waldorf Blue Suede Coat, alloy console chassis
Dimensions: 11" width, 5 3/8" to 5" height, 1 7/8" to 1 3/8" depth including 1/8" rubber feet"
