"Works, Ltd. is a small manufactory located in Austin, TX. We are dedicated to the small scale production of high quality goods. We have been building synthesizers under the "Bananalogue" name for 10 years."
"What is the Bananalogue LPFA? It is an analog low pass filter for use in the Frac rack system of modular synthesizers. The design is based on the original Arp 4075 filter submodule. The 4075 was the building block of many Arp electronic music instruments such as the Odyssey III, Axxe, Omni and Avatar.
About the PCB
The PCB for this module was designed by Rob Keeble of the Emulator Archive. The PCB is very high quality with blue solder mask, double sided layout with through hole plating. The PCB is manufactured in the USA.
The board uses 15V and the dimensions were designed to fit within the Frac rack system, but could be adapted for use into any of the other 15V synthesizer systems such as MOTM, dotcom, Modcan etc etc. Pledges for the bare PCB will also include a 9 page .pdf construction manual.
About the Module
The filter has a very smooth and musical quality. It was originally designed by Arp in response to the threatened Moog lawsuit, so as you can imagine it has its own unique character.
The LPFA is thermally compensated on the 1v/oct input so it can track decently over several octaves for use as a sine wave oscillator. The module also has three attenuated inputs for use as a utility mixer if the cutoff is thrown fully open.
The front panel of the module is made of aircraft aluminum, laser engraved with yellow paint filled legends. The faceplates are manufactured in the USA. The module is designed to integrate fully into a Frac Rack system modular synthesizer system. The Frac Rack aka Fractional Rack aka FracRak is a system popularized and supported by PAIA, Blacet, Wiard, MOTM, Metal Box and Bananalogue. There are a wealth of interesting modules available at a good value in this format and we hope the successful funding of this project will allow us to continue supporting this format and the SDIY community.
The cost of parts and metal has sky rocketed over the last few years since we last undertook the manufacturing of the LPFA module. In turn this has prohibitively raised the start up cost for producing a module of this quality. The purpose of this project is to provide the module to the niche market that can utilize it, while simultaneously defraying the initial production costs. We hope you will enjoy your module!"
