The FFT ed­i­tor

Computer Music - - Make Music Now -

The FFT Ed­i­tor is a sort of EQ on steroids, giv­ing you exquisitely fine con­trol over the har­monic con­tent of the sig­nals out­put by the Ba­sic and Shape Os­cil­la­tor types. Es­sen­tially, you use it to ad­just the lev­els of both har­monic and in­har­monic bands in one of three modes.

Har­monic mode presents all the har­monic and in­har­monic bands as a row of ver­ti­cal slid­ers – sim­ply drag them up and down to raise and lower their lev­els. The light­est bands are the oc­taves above the fun­da­men­tal – the num­ber be­low each one tells you which oc­tave it is, with the fun­da­men­tal be­ing 00. The darker bands – in­di­cated by the 7th mark­ers be­low – are the quint par­tials; and the dark­est bands are the in­har­monic bands of the next har­monic to the right. While Har­monic mode snaps your ed­its to spe­cific har­mon­ics, quint par­tials and in­har­mon­ics – ie, a se­lec­tion of mu­si­cally use­ful bands – Bin mode gives you ac­cess to all 256 har­mon­ics, with the abil­ity to zoom in on the dis­play us­ing the mouse wheel. Next, there’s Free mode, which lets you draw in your own har­monic re­sponse curve com­pletely free­hand.

The row of knobs at the bot­tom of the FFT Ed­i­tor dial in low- and high-pass fil­ter­ing with vari­able slope set­tings, and ‘spec­tral sweep­ing’, which means shift­ing the edited bands and har­mon­ics left and right. The Flip set­ting, mean­while, pro­gres­sively in­verts the bands, so that cuts be­come boosts and vice versa.

Per­haps the most in­trigu­ing FFT con­trols, though, are the VSpeed and VStrength pa­ram­e­ters, which dial in the rate and depth of LFO-style up/down mod­u­la­tion for in­di­vid­ual bands, let­ting you cre­ate spec­tac­u­lar mor­ph­ing ef­fects.

The FFT ed­i­tor is far more than a fre­quency anal­yser, let­ting you scoop and morph the sound in new ways
