STM32F103 on eBay: ebay.to/2HPiuT7
This is a digital Leslie emulation I made this afternoon using a STM32F103C8T6 microcontroller and a R2R Ladder 16bit DAC.
This setup features:
ADC at 48KHz sample rate
32bit internal operations
pedal connection for speed toggling
configurable fast speed
configurable low speed
configurable ramp up speed
configurable ramp down speed
configurable mic distance to the speaker
delay unit with configurable time and feedback
What's missing:
improve the signal/noise ratio in the input stage
implement dynamic frequency filter according to the rotor position
implement separated upper and lower rotor effect
implement stereo
implement MIDI to control the speed
I'm playing a Hammond-like sound on my Yamaha Motif ES6 with some distortion, but without any Leslie.
