Sept 17: Dual Trills by C C O published on 2017-09-30T13:58:55Z This month we have a patch using two unrelated square LFOs for trills on two VCOs. One is static and the other modulated. Here are the Dual Trills. First, we have an Addac 701 as the first LFO doing a minor third on a Cwejman VCO6 (using the square 1 output). The 701 square also clocks an Audio Damage Sequencer 1 (I use the inverted output on the 701 so that the sequencer advances on the lower note of the minor third). Basically, the sequencer is just used to create random modulation values from the internal LFOs. The gate output also triggers an ADSR-VC2. Then, we have a second 701 and also a second VCO6. The 701 again is in LFO mode and creates octave trills on the VCO6 (where the saw “PWM” wave is used). Both VCOs are then routed to a MMF6 and then to an Addac 802 for the final VCA and out to the DAW. The 802 VCA is gated by the ADSR-VC2, while the second envelope on the ADSR modulates the MMF6. Furthermore, there’s FM on the MMF6 from the octave trill VCO, a slow LFO from a Doepfer A143-3 and “key tracking” from the square LFO doing the minor third trill. The A143-3 also provides PWM to the two VCOs and vibrato on the octave trill VCO. Finally, as mentioned, two S/H LFOs are created internally on the clocked Sequencer 1 (using the + / 0 / - setting, which basically provides three different values that are chosen randomly). The first randomizes the ADSR decay, the second the frequency of the LFO doing the octave trill. Finally, the A143-3 LFO doing PWM on the minor third trill VCO is used to PWM the LFO doing the octave trills. The patch is also very much based on playing with the level of the filter audio inputs. The buildup takes a bit of time. I recorded everything in one take, no edits needed. Couldn’t resist adding a return track from a RE201 after the fact (you can hear its noisefloor rather well in the quiet beginning). As always, some delay, reverb (Valhalla Vintage Verb in plate mode), EQ and compression in Ableton to bring it together. Hope you enjoy it and cheers!
