Modular Products
Do you provide DIY kits for your products?
No, we do not provide DIY kits for our products for two reasons. The first reason is that the majority of components are SMT (surface-mount-technology) for our circuit board assemblies. Therefore the cost of a DIY kit would be close to the cost of a completed module build. The second reason is quality control of our products, which we take very seriously.
Do you sell products directly from your website?
While we do sell the NoisySix kit (for the Polysix) directly from our website, our Eurorack modules are only sold through our retailers. A list of retailers can be found here.
AWM-3
Is there an operation manual for the AWM-3?
We are currently working on an extended (detailed) user guide for the AWM-3 (this Support page will be updated here with a link once the guide is published online at our site.
Our AWM-3 Quickstart guide can be found here.
Also, a block diagram of the AWM-3 architecture can be found here.
Are there audio / video demos for the AWM-3?
Yes. You can hear and see demos on our AWM-3 Youtube Channel here.
What is the current draw for the AWM-3?
+12V @ 77mA
-12V @ 77mA
What are the features of the AWM-3 in detail?
The AWM-3 quick-start guide can be found here. However, we are currently working on an extended user guide for the AWM-3 (coming soon)
VCF-74
Is there an operation manual for the VCF-74?
Our VCF-74 quick start guide found here is our operation manual for the VCF-74
Are there audio / video demos for the VCF-74?
Yes. You can hear and see demos on our YouTube channel here.
What is the current draw for the VCF-74?
What are the features of the VCF-74 in detail?
The VCF-74
Is there an official calibration procedure for the VCF-74?
Yes, there is an official calibration procedure documented for both the Mk1 and Mk2 versions.
For Mk1, use the VCF-74 Mk1 Calibration Procedure (ver 0.6, July 2018)
Is there a band-pass feature for the VCF-74?
Inherent by design, the VCF-74 provides simultaneous, cascaded (series) high-pass and low-pass filtering, and is therefore also a variable band-pass filter. The design is such that the input signal is scaled (gain / attenuation), then fed into the HP filter, then into the LP filter, then to the output scaling (gain / attenuation). Hence, the two filter stages can be set as a low-pass, high-pass, or band-pass filter with an infinite number of possible bandwidths within the frequency response of the VCF-74. Hence, the output signal is a product of both filters, including independent cutoff and resonance controls.
What does the boost switch do on the VCF-74?
The boost switch on the VCF-74 is simply provides an approximately 5dB gain to the signal from the HP circuit to the LP circuit. In the non-boost position (switch to the left), the signal path has a similar gain structure to the original Mini-Korg filter circuit. However, when the boost is applied (switch to the right), the signal is about 5dB higher going into the low-pass filter circuit. This not only saturates the LP circuit, it changes the balance of resonance for both circuits as well as adds a natural, organic sounding compression.
Will you be providing a DIY kit for the VCF-74?
We do not have plans to manufacture and provide a VCF-74 kit at this time. There are 197 components (total), most of which are SMT (surface-mount technology) components built onto the circuit board assembly for this module. This filter design is of a discrete topology, which essentially means that there are many individual components--and therefore a DIY kit version with all "through-hole" type components (commonly found in DIY kits) would not fit onto a PCB for a 14hp Eurorack module. Kits with SMT populated PCBs will also not be made for the simple reason that we would like to guarantee quality control over the VCF-74 build, calibration, and testing.
NoisySix
Is the NoisySix compatible with Tubbetec products, such as the ModyPoly™ and Polysex™?
Yes. The NoisySix is compatible with both the ModyPoly™ and Polysex products. There are no known issues as of this time (8-July-2016).
Is the NoisySix™ compatible with the KiwiSix™ upgrade for the Polysix™?
No. The NoisySix is not compatible with the Kiwisix™. The Kiwi upgrade for the Polysix replaces the original CPU board (KLM-367A), which has essential components and configuration, per original design of the Polysix, that must be present in order for the the NoisySix to adapt properly.
How do you install the NoisySix?
The Installation guide for the NoisySix can be found here. Please review the document entirely before purchasing and attempting installation of the NoisySix. In summary, it is advised to have the NoisySix installed by someone with experience and proficiency in soldering and reworking printed circuit boards, especially in the domain of vintage analog synthesizers. While a moderate amount of experience is necessary to follow the instructions, it is recommended that you adhere to all ESD practices. Also, please read the health and safety warnings, and disclaimer in the installation guide.
What is the range of frequency for the LFO?
The range of frequency is generally 2 minutes at the slowest speed and as high as 100Hz for the fastest speed. However, while each module is calibrated before being packaged and shipped, the rate of oscillation will vary slightly from each upgrade kit. The minimum guaranteed range is 2 mins -to- 100Hz, regardless.
