Let's dive in.
Subtractor: Filter 1 Frequency, LFO 1, Amp, FM
NN-19: Filter Frequency, LFO, Amp
NN-XT: Filter Frequency, Mod Decay, LFO1 Amt, Filter Resonance, Level, LFO1 Rate.
Thor: Anything (via Mod Routing)
This is not a bad list at all, and you can, in fact, make tons of great patches with just the front panel controls, except for Malstrom, which has no BC front panel controls.
But what if... you want breath to control Subtractor's noise oscillator, or the filter resonance on NN-19, or anything on Malstrom? Or even control parameters on a Scream 4 distortion?
Technique Number 2 - RPG-8 Arpeggiator Technique
Step by Step
- Create a new Combinator by dragging a Combinator from the tools window over to the rack. (You can show the tool window by pressing F8)
- Add a line mixer 6:2 by dragging it from the tool window to the combinator. I start every combinator with this device.
- Add an RPG-8 Arpeggiator by dragging one to the Combinator window while holding the Shift key so that nothing is auto-routed. We aren't using the RPG-8 for its sound but for its CV signal routing capabilities. Turn the Arpeggiator off by clicking the 'ON' button so it is dark. Label this device 'BC Router'
7. Connect the Breath CV output of the RPG-8 to the Split A input on the Spider. This turns our 1 breath output into 3 breath outputs and one inverted output. The 3 regular outputs track our breath input normally -- 0-127 goes in, 0-127 goes out. The inverted output outputs 127-0 for an input of 0-127. Why is this useful? Well, if you want one value to go up and another to go down, you could use the inverted output to make the value go down.
a. Filter: 64
b. Shift: 32
c. Level: 85
10. Congratulations, you just created a Breath Controlled Malstrom!
