Xilinx Spartan-3 FPGA emulates an old Hammond B3 organ. Absolutely NO computer or DSP involved, all sounds generated by XC3S400 FPGA. Audio output by CS4334 24bit DAC. Just a Leslie-wannabe added.

Amazing ! Thanks !
-
DUde, do you have any paper for us to read and get into your work? Thanks!
-
A tube in an FPGA circuit? YOU are MAD!
-
Damn Dude!!! this was a great implementation! Good Job!
-
Great job
-
Waouuu ! Incredible !
But the name "HOAX" makes me think it's a joke !
Is it really serious ????

I really like your project. Could you please tell me, how did you cope with multiple keys pressed simultaneously? I mean DSP stuff: summing of several signals and scale them into 24bit resolution.

@amplifier88 Generator resolution is 12 Bit and notes are added to 24 bit busbar accumulators, truncated to 16 bit audio finally. Generator signals are compressed in volume as on a real hammond when pressing several keys that access the same generator note, simulating the load sag.

@MrBuexav
HOAX stand for "Hammond on a XILINX (FPGA)". Yes, it's real (physical modelling). See my other videos for further details.

Very cool!
Where you buy the controls keys?

The drawbars were scavenged from an old WERSI organ. The illuminated momentary switches are from MEC denmark, called IlluMEC.
