HX3 organ module
The Hammond® B3 and A100 have remained out of reach of tonewheel emulation, even from well-known brands, as common approaches in emulation have failed to catch the true soul and spirit of a genuine vintage tonewheel organ. Primarily, this is due to use digital signal processors (DSPs) or sample players for tone generation and key gating. While this works well for audio effects and low-demand audio generation, the complexity of the “Hammond sound” requires a high-performance approach to address the parallelism found in a tonewheel organ.
Our genuine gate array chip (FPGA) handles all tone generation, key gating, vibrato/percussion effects, and audio processing in parallel. The tonewheel, line box capacitor, and tube has its own dedicated digital counterpart inside the gate array. Furthermore, there are no time-consuming DSP subroutines to call. Therefore, audio generation is instant and latency-free. Even if you lay your arms across each manual, there are no notes missing and no drooping in treble response.
The FPGA does a beautiful job in recreating a rotary cabinet effect in the style of the legendary 122 type amp. It uses a 512-pole FIR filter to exactly resemble the behaviour and frequency response of the Jensen® V-21 driver mounted to its rotating horn assembly.
