How it is made
Original sOURnd design blending general techniques: three parallel trapezoidal band-pass filters at typical published formant frequencies of eleven vowels, fixed peak gains, geometric interpolation between two vowels, an LFO and input envelope follower on the morph, with makeup gain and a soft shoulder.
