New Steffcorp 2600 VCO (ARP 2600) DIY Kit


via Thonk

"The Steffcorp 2600 VCO is an analogue oscillator with full voltage control based on the 4027-1 ’VCO-2’ oscillator used in the ARP 2600. It’s not just a copy however, we have gone to great lengths to bring it into the 21st century. A much needed precision reference voltage was added, as well as buffers and a few other goodies. Going SMT offered the means of improving the PCB-layout even further, as well as a selection of easy-to-source parts. No more treasure hunts and extravaganza prices! On top of this, a good bit of time was spent on analysing and comparing modern parts to find the best matches for the original part specifications."

You can find some additional modules by Steffcorp announced in this post.

"Starting to make this monster musical.
Main bassline is STEFFCORP ARP2600 Modules.
3x Oscillarp VCOs, 2x Envelarp ADSRs, 2612 VCF and a Arplifier VCA.
Also Frequency Central's LFO range giving the Steffcorp modules some PWM movement, with Doepfer Spring Reverb & some Maths fucking with the FC Raging Bull and Electro Cardiogram filters on the noisy bits.

Time to go John Foxx I think..."

Steffcorp - ARP 2600 Eurorack Modules by Rickard Steffensen


It looks like have a new eurorack manufacturer in town, Steffcorp from Rickard Steffensen (see the Steffensen channel for previous posts).   Steffcorp appears to be the new official branding for his work.  According to the about page Steffcorp will initially focus on ARP 2600 modules in eurorack format.

"After passionately working with synthesisers for over 20 years, doing both music and a lot of sound-design, i started a journey 2 years ago recreating my favourite synthesiser of all time – the ARP 2600.

As the eurorack format seemed to have the most to offer, and having worked with software/DSP modular’s for quite some time, i soon realised this was the format of my choice rather than locking myself in to a closed structure. Nothing wrong with that obviously (!), just not my kind of thing...

I am now working hard on getting a full voice of 2600 modules out the door, followed by other even older designs that deserves to be revived!"

The following is their current line-up:


VCF 2612

"This is a clone of the 4012 VCF used in the ARP 2600.
Other than some substituted parts and a “sandwich-layout” mainly adjusted for the eurorack standard, I have tried to keep all the original quirks as close to the original as possible.

The 'sandwich-layout' simply means the VCF is split in 2x PCB’s mounted in parallel on top of each other.
The Core-PCB contains the main circuit, while the Control-PCB contains the controlling elements as well as the buffers."


Oscillarp – VCO

"This is a eurorack-clone of the 4027-1 VCO used in the ARP 2600.
Other than some needed part substitutes, removal of low-frequency option, added hard sync and a “sandwich-layout” adjusted mainly for eurorack, I have stuck with keeping it as close to the original as possible.
This means it will retain all the original quirks of the 4027-1, which also enhances the personality of the oscillator.

The 'sandwich-layout' simply means the VCO is split in 2x PCB’s mounted in parallel on top of each other.
The Core-PCB contains the main circuit, while the Control-PCB contains the controlling elements as well as the buffers."


Envelarp – ADSR/AR

"This is a eurorack-clone of the 4020 ADSR/AR used in the ARP 2600.
Other than some substituted parts, an added comparator on the input and a layout mainly adjusted for the eurorack standard, I have tried to keep all the original quirks as close to the original as possible.

Sometimes less options is a good thing. Sometimes you want good results fast.
This is where the Envelarp comes in. With it’s down-to-the-point controls, it can quickly help you dial in your needs without getting stuck in options.

From smacky snappiness to the softest swell, it does all this with ease.
However, even with its “limited” controls, it still offers a great deal of experimentation if you wish.
With a separate input for Gate and Trig, one can create some very interesting results. Especially combined with various Gate lengths."


Arplifier – VCA

"This is a eurorack-clone of the 4019 VCA used in the ARP 2600.
Other than some substituted parts and a “sandwich-layout” mainly adjusted for the eurorack standard, I have tried to keep everything it as close to the original as possible.

The “sandwich-layout” simply means the VCA is split in 2x PCB’s mounted in parallel on top of each other.
The Core-PCB contains the main circuit, while the Control-PCB contains the controlling elements."
