The Infinity project is my holy grail. If you just tuned in recently, you might ask what is that? Well, In a nutshell: “Polyphonic sustain,…
My holy grail… It’s been on the back burner for far too long since after its inception in 2014, giving priority to other projects such as the…
This D string was driving my pitch detector nuts. It’s jumping from fundamental to octave and back all over the place. Can’t make up its…
I needed to implement real-time, multichannel pitch detection in software using a small ARM Cortex-M4 microcontroller (MCU). My all-time favorite is the STM32F4 family from…
Gone are the days of DIP (Dual in-line) ICs. Most modern ICs are no longer offered in easy to use 2.54 mm (0.1 inch) pitch…
Infinity… It’s all about sustain. Our goal is and will always be polyphonic sustain. Polyphonic sustain, plus extensive processing for each string, will give us musicians full control…
What do I do on Christmas eve? What else, but hack some C++ code. I got a new highly optimized sustain driver design that also acts…
After a few iterations using my favourite graphics tools (Photoshop, Illustrator, iDraw, and Solidworks (for anything 3D)), I think this is the minimal interface I really like.…
From 3D model to actual prototype, here’s the Infinity Driver v0.93, front and back views. The coils are 16Ω gauge 35 magnet wire, with Neodymium N42 core. The…
