This filter uses the same topology as the Shruthi SMR4mkII, with the following change: OTA / op-amp integrator cells are replaced by OTA-C-Darlington buffer cells. This saves a quad op-amp which wouldn’t have fit on the board. The difference can be heard when increasing the resonance.
While this product is in fact an Ambika originally designed, sold and supported by Mutable Instruments, it is no longer manufactured by them and therefore is not supported by Mutable Instruments. Any requests for help troubleshooting issues as they arise during a build that are sent to Mutable Instruments will be ignored. Please, send any support requests to us, Laurentide Synthworks, or to the SDIY community forums - not to Mutable Instruments.
Although this is not an official Mutable Instruments product, we have been in contact with them during the whole process of continuing the legacy of the Ambika Polyphonic Hybrid synthesizer. All Mutable Instrument's Logos have been removed from all of the products and replaced with our logo (with the exception of the SVF & 4P Voicecards. These were part of Mutable Instruments remaining stock after it was discontinued). A disclaimer on every LSW PCB reads "Originally designed by Olivier Gillet for Mutable Instruments, cc-by-sa". Basically, what this means is this is no longer a supported product of Mutable Instruments, but rather Laurentide SynthWorks. It carries a Creative Common's license which allows anyone with the PCB files and code to manufacture them, as long as any changes to the design are also shared under the same license. Although the license does not require the original designers name/logo to be removed from the product, we felt it best to adhere to Mutable Instruments wishes regarding this matter. They want to distance themselves as far as possible from this product and we ask you, the purchaser, to respect their wishes when it comes time to ask for some troubleshooting guidance.
