	Late 2023 versions of HX3.5 sound engine do have a nice spread modulation, but suffer from modulation artefacts, especially on rotary FAST due to a too high "diffusor spread" modulation. We reduced spread modulation in 2024 FPGA sound engine versions to avoid these.		Late 2023 versions of HX3.5 sound engine do have a nice spread modulation, but suffer from modulation artefacts, especially on rotary FAST due to a too high "diffusor spread" modulation.

			Diffusor spread modulation is derived from LFO Mod factors, it has no separate parameter to tweak. We reduced spread modulation in 2024 FPGA sound engine versions to avoid these.

	While clipping will sound like a very hard overdive, modulation artefacts are "swirling" noises and non-harmonic "alias" frequencies. Modulation artefacts are independant from swell pedal setting; they may occur when modulation depth of vibrato, phasing rotor or rotor/horn delay is set too high. Mostly modulation artefacts are caused by rotary horn modulation, especially on rotary FAST.
