Animusic 2 - Cathedral Pictures (complete!)

YouTube via Mechaffix326. You might remember Animusic from this post.
"Visit www.animusic.com if you're interested in watching this amazing Animusic video, along with seven, fourteen, or more other Animusic videos, with better picture and sound quality on DVD.

This is a computer generated video showing robots and self-operating instruments playing classical music inside a large building. There are pipe organs, clarinets, and flutes that emit light-beams as they play notes; some trumpets and tubas affixed to walls, and they stick out when they play individually; a one-stringed rock bass guitar played by a couple of robot hands that slide up and down its neck; a yellow synthesizer; and a drum set, and two large, curved instruments, the hammered dulcimer and the xylophone, played by robots that pivot and slide back and forth to hit their mark.

The music on this piece is from 3 movements of Mussorgsky's "Pictures at an Exhibition" ten-piano suite.
They are:
"Promenade" [from start to 1:38]
"Hut on Fowl's Legs (Baba Yaga)" [from 1:38 to 3:45]
"The Great Gate of Kiev" [from 3:45 to end]

Do you notice the picture on the bass drums? It is a drawing of the Great Gate of Kiev complete with a bell tower to its right.

Some people have experienced Emerson, Lake & Palmer playing music that is very similar to this one."

Roland JX-3P

images via this auction

"Killer DCO analogue synth. Shares the same VCD chips as the Jupiter 8 (Roland IR3109 IC ) which are great sounding, rock solid, and will likely last forever. The rackmount version on the other hand are the same filter IC's that are in the Juno 106, the 80017a which are dying left and right from old age and in need of replacement. The unique polyphonic step sequencer (doesnt output to midi and syncs to Trigger voltage) and the vintage Roland style hold-transpose that are on the JX-3P are not to be underestimated. It's a long running debate, and an annoying one.. but I'll say it anyways. I would much rather have a JX-3P than a Juno 106 any day. There's an amazing and easy Mod for the 3P (search for JX-3P MIDI Mod) that enables realtime use of the control box + midi input at the same time, and many many other features including all parameters editable by MIDI CC

Polyphony - 6 voices
Oscillators - 2 DCO's per voice
Memory - 32 preset, 32 user
Filter - Resonant Low pass
Effects - Chorus
Arpeg/Seq - Simple Sequencer
Keyboard - 61 keys
Control - MIDI (no velocity except with a special ROM upgrade)
Date Produced - 1983"
VCDs? Anyone know about the Jupiter-8 comparison?

Update via Dave Cornutt in the comments:
"According to analog.no, the IR3109-based VCF was indeed used on the Jup8, as well as the other Jupiters, the Juno 6 & 60 and the first version of the MKS-80. The IR3109 is an operational transconductance amp, and all of the classic Roland filter designs are OTA-based.

The infamous 800017A actually contains an IR3109, so electrically it's the same. The problem with the 800017A is apparently a fabrication problem that allows metal migration and shorting between leads on the micro circuit board embedded in the IC.

As the poster noted, the MKS-30, which is the rack mount version of the JX-3P, uses the 800017A. I also know that the GR-700 guitar synth uses it too."

CR-78 Restoration

YouTube via MusicMiK.
"Okay, no new synthesizer modules, as i'm on holiday and just was at home today with a new toy - a CR-78 from a friend which needed a repair/restoration.
Just a short test video here, the full restoration story follows soon, for now, there is just a bunch of photos created during the day:

YouTube via MusicMiK. You can see the previous videos by MusicMiK posted here.
"It took quite a while due to vacation and some stress the last weeks, but finally, i soldered this module together. This was sort of much more difficult due to the very compact layout i needed so save some space in the overall construction behind those modules.

As usual, you can find more information about the project and the schematics for the modules via the blog: http://www.mik-music.org/tiki/blog1"

"this is before I got my 4-channel speaker system -- its all coming out of an old stereo with one bad channel. and no -- no arbitrary function generator (aka sequencer). some great sound I stumbled on soon after getting this machine....."

Gakken SX-150 Schematic

via HOSHUYAMA on AH.
"Its schematic is already revealed in its instruction manual, however, it does not include component values. To get the schematic with component values, which is essential for us, I made one from the open information on the internet and some measurement of an SX-150. Actually, this small synth was designed by our Naoki Iwakami (AKA. "GAN" in this list). The design is unusual to save the cost, but very clever and unique!"

ARP Odyssey Oscillators - Clone

via AndyR1960 on this electro-music.com thread.

"I've just built a clone of the ARP Odyssey Oscillators (MkIII), including the Ring Mod - All works great, very pleased. ...except that the oscillators are locking together when I get close to unison.... it's an exact copy of the Oscillator section of the PCB, and no component substitutions have been made, apart from using good quality WIMA 680pf timing caps instead of polystyrene and multiturn trimmers."
