As we get closer to the end of our first crowdfunding campaign, we would like to share a rather unique feature of our board with the audiophiles out there. It’s a synth!
We have digitally reconstructed a vintage organ (guess which one!) in the digital interface of ULX3S. With this simulation of a very famous vintage organ’s tonewheel, our lab member EMARD created a polyphonic synthesizer with parameters that are configurable through a MIDI interface.
It is a true polyphonic additive synthesizer, implemented in a parametric VHDL core, with support for realtime performance.
Polyphonic synthesis is inspired by a set of multiple rotating tonewheels with electromagnetic pickups such as those found in a Hammond organ, which has a set of drawbars that mix sine wave harmonics to produce characteristic tonewheel waveforms.
SynthoWheel was not created to reproduce a historical sound, but to generate numerically controlled polyphonic sounds using an FPGA. We are in no way suggesting that it can replace original sound synthesizers and organs.
However, the fact remains that using advanced technology to reconstruct old and obsolete technology allows a wider audience to enjoy that vintage analog synth sound.
Thank you very much for your support. We are looking forward to shipping your boards and seeing what you do with them. (Whether you are an engineer or a musician!)
All the best from the Radiona team!
