12db Squawk with 24db Legato
The idea behind this patch is pretty simple: create a smooth lead or bass with harsher 12 or 6 db squawks accenting the first note you play a legato sequence. VCA-B’s trigger input is normalled to the gate out. So, by default, when playing legato you only get a filter blip on the first note. We’re getting the main part of this patch for free.
Oscillators:
1: Set VCO-B to take the pitch from VCO-A.
2: Tune VCO-A and B both to C4.
3: Push up VCO-A triangle wave in the mixer.
4: Patch VCO-B triangle to the mixer, and push the slider up.
Envelopes:
1: Set ENV-A level switch up to receive velocity.
2: Set the ENV-A speed switch to medium.
3: Set the attack slider all the way down for an immediate attack. Set the decay and sustain sliders all the way up. Set a low release time.
4: Set ENV-B’s mode to envelope, and type to AD.
5: Give it an immediate attack, moderate fall, and a fairly exponential decay shape. You can set this to taste, the goal is to create a fast accent-like envelope.
Filter:
1: Tune the filter to B3 (or to taste).
2: Set a moderately high resonance. Don’t let it go into self resonance, but the high Q factor is what’ll create the acid squawk.
3: Turn the VCF level knob up until the signal from the mixer just starts to turn red.
4: Set the pitch FM to about +50%.
5: Set the filter envelope FM amount slider up about halfway.
6: Set the filter mode to LP2 (12db lowpass). Try switching between LP1 and LP2 to see which you like more.
VCA:
The filter output is normalled to the selected mode. However, the goal of this patch is to get a bright and crunchy blip on the attack, followed by a smoother sound on any following notes. To achieve this you need to send LP4 to the VCA-A mixer and modulate LP2 with VCA-B before sending it to the VCA-A mixer.
1: Patch the LP4 output to the VCA-A audio in.
2: Patch the standard VCF out to the VCA-B audio in.
3: Patch ENV-B to the VCA-B CV in.
4: Turn the VCA-B CV amount knob fully clockwise.
5: Set the VCA control switch to the up position.
6: Patch from the VCA-B out jack to the VCA-A aux in. Alternatively try patching out from the LPF-B out jack. See which one you like best. The LFP should make the sound get darker faster.
This variation uses the LFO to move the resonance up and down, bringing the squawks in and out.
1: Take the same patch as before.
2: Patch LFO Y and Z to the sum inputs.
3: Then patch the sum out to the VCF Q mod in.
4: Raise the Q mod slider to about halfway.
5: Drop the Q slider to a moderately low amount.
6: Set the LFO rate knob to tase.
7: Try switching the LFO Y and Z rate divider knobs to different values so the sound will come in and out at less regular intervals.
