> Step by step Get­ting started with Au­dioThing The Orb CM

Computer Music - - Free Software -

1 To in­stall The Orb CM on your sys­tem, down­load the PC/Mac in­stall­ers from vault.com­put­er­mu­sic.co.uk (reg­is­ter is­sue 241), or find them on the cover DVD that comes with the print edi­tion of this mag­a­zine. Dou­ble-click the in­staller for your sys­tem and fol­low the sim­ple pro­ce­dure to in­stall. 2 Open your DAW, then load up an in­stance of The Orb CM as an insert ef­fect over a har­mon­i­cally-rich sound. Un­der its fu­tur­is­tic blue hood, the plugin uses a for­mant fil­ter (a trio of ze­ro­feed­back par­al­lel band-pass fil­ters) to mimic the res­o­nances of the hu­man mouth. Crank Mix up to 100%, so we only hear the fil­tered sig­nal. 3 The Orb CM’s main cen­tre sphere is di­vided into five seg­ments, each rep­re­sent­ing a vowel. To fil­ter your sound, sim­ply click and hold on the dot, then drag it around the orb. For now, keep the dot’s range of mo­tion within the bot­tom seg­ment (the ee vowel) as you sweep it about. Hear the dis­tinc­tive “eee” fil­ter­ing ef­fect we’re cre­at­ing? That’s for­mant fil­ter­ing, folks! 4 Each of the orb’s five vowel seg­ments can be changed to one of ten vowel types – ah, e, ee, u,o, i, ae, aw, a and er – by click­ing on the vowel name and se­lect­ing one from the drop­down menu. Here, we’ll click our bot­tom ee vowel header and change it to the er op­tion for… er… an er ef­fect! 5 The dot’s dis­tance from the orb’s outer edge de­ter­mines the fil­ters’ Em­pha­sis (ie, res­o­nance) amount: keep the dot in the cen­tre, and the fil­ter sounds like a reg­u­lar band-pass type; drag the dot to the orb’s edge, and the fil­ter takes on a sharp, nasal, vowel-like tim­bre. 6 Now click and sweep the dot from our bot­tom er seg­ment to one of the ad­ja­cent seg­ments (u or e) – keep the dot along the outer edge for max­i­mum Em­pha­sis to hear the ob­vi­ous voice-like ef­fect. No­tice how the tran­si­tion be­tween dif­fer­ent vow­els is pretty smooth? Well, the Smooth dial de­ter­mines how smooth: 0% gives a harsh, stepped tran­si­tion; while 100% gives seam­less in­ter­po­la­tion. 7 The bot­tom-cen­tre Gain dial (-inf to +12dB) sets the for­mant fil­ter’s gain, and Mix (0-100%) lets you blend be­tween the dry and fil­tered sig­nal. Keep­ing the Mix at the max 100% re­ally thins a sound out, so if you want to dial back its ef­fect, set a low Mix of 10-20%, then crank up the fil­tered sig­nal’s Gain un­til the fil­tered sig­nal adds an ex­tra di­men­sion to the dry sig­nal. 8 The Orb CM’s res­o­nant for­mant fil­ter­ing can get pretty wild, caus­ing jumps in level now and then – so the plugin has an out­put Lim­iter to pre­vent over­shoots, which is tog­gled via the top More drop­down. Ei­ther side of that is a

Ran­dom but­ton for ran­domis­ing all set­tings, and an On/Off switch for by­pass­ing the plugin.
