Frame Dragging Vortex - Featuring Novachord Sample Set

"This is a piece titled "Frame Dragging Vortex", from the new Atomic Shadow project called "Creatures From Beyond". It was made with Hollow Sun's terrific Hammond Novachord instrument, Roland Gaia and Strymon's wonderful El Capistan tape echo. The arppegiated pattern is the Gaia run through the El Capistan tape echo pedal. Everything else is Novachord"

ARP 2600 2601 v1.0 with 3620 keyboard

via this auction

"The “orange and black” 2601 is the last 2600 version produced by ARP. It is the most reliable version, an update to the more common grey version. None of the modules are set in epoxy, making it more serviceable in the long run...

Here are a list of the specific repairs:
4 slider tips were repaired with identical replacements.

NOS power connector was re-fitted (comes with original cable)
NOS handle was fitted (quasi-identical)
NOS keyboard connector was fitted
Some Polyfusion-specific internal normalization was removed
Polyfusion front panel gate input removed and capped
2 Polyfusion connection inputs removed from the left side and patched
(one tiny hole on upper right panel left (see pics)
new orange LED in the power indicator
New capacitors on the power supply
Tolex on both cases was cleaned and refinished.

Additionally, my tech performed some great modifications :

Filter upgrade :
the 4072 filter was upgraded to correct the “error” causing the filter to open to a maximum of around 12k, now it's nice and bright when fully open (28k apparently). The filter kept its original character, just with extended range. The upgraded 4072 is a very nice sounding filter, just as good and useful as the previous moog-like filter Arp used, but a bit more unique and exclusive!

Reverb upgrade :
The reverb tank was changed top a looong type 9 NOS replacement. The first 2600s' had this type of tank and are known for their longer, fuller reverb.

The original reverb tanks were made by Hammond, their reverb division then took the name Accutronics. Thankfully I was able to purchase a remaining american made Accutronics tank (now made in Korea). The original small tank is included in the auction as well. My tech also performed a modification to lower the noise floor, and made the connections balanced using good quality cables (Canare). I am a fan of spring reverb and own a few and was very pleased with how this one sounded! The tank has been mounted vertically to avoid interference with the speakers at max volume but can still occur if you try hard. These mods, along with new caps on the power supply and proper calibration, greatly improve the 2600's signal-to-noise ratio." Additional pics here.

Haible (JH.) String Filter Prototype

via this auction

"This is my Prototype of the "String Filter" Project

It's tested, adjusted, and consists of two populated PCBs

For building a complete synthesizer module, some diy work is still needed, connecting front panel elements (not included), but the populated and tested PCB will certainly make the DIY efforts a lot easier than usual."

Phisynth - Max/MSP Synth Featured on Cycling '74

via Philippe

"This instrument was created as part of our latest dance spectacle Absorbe-moi

The starting idea was to create an instrument dealing with sound synthesis and reacting directly with the movement of the 2 dancers. Their movement is tracked live and analyzed by another computer, then the main characteristics of it (X position, Y position, Height, Width, X gravity, Y gravity, speed and luminosity) is smoothed and transmitted as normalized data into the synth and used (of course with some latency) to modulate any selectable parameter of the sound in real time (external modulation sources 1 to 8).

Inspired by some of the tools I regularly use and love (Access Virus TI, Nord Modular G2, Native Instruments FM8 and Massive) I soon began to build my dream synth, with all the features I wanted, some of those only partially available in the products mentioned above.

"This is the first run / tewst of my brand new OSC303 module.
It is a 1:1 rebuilded TB 303 Oscilator made by dinsync.info
I triggered it with a doepfer a155 , and i used a doepfer ADSR and a A103 filter from doepfer. i just played around with it so it´s not a 100% Tb 303 patch. i will figure the right settings out and post some more videos."
