Hi guys

Some more analyses on the bump : I have noticed that the bump is very likely a product of the envelope itself . By measures it should be around 60ms (50ms clip +10ms decay) and its amplitude should be equal to the top sustain level for VCA and maximum cutoff point for the channel filters; it relates to both Filter EG and VCA EG.
By the way , I have the feel that the highest cutoff you can reach with the channel filters controls is NOT 25KHz but rather something around 12KHz. This results from an FFT ( wav file: 32bit/192KHz ; FFT:welch , 65K harmonics, 70dB amplitude range) of open LPF or HPF without resonance ; my guess is that can relate either with the EG and the master Brilliance control, the former to prevent an excessive excursion of the AL at high cutoffs and the latter to allow some further modulation space .
Anyone can enlighten me about these statements?
Please dont' leave me without an answer........ :-(
