PotD - Brains Releasequence
Today's Patch of the Day showcases some of the features that make the combination of Brains, Pressure Points and Maths such a flexible & tactile sequencing package.
Here are the patch details:
Cycling Maths Ch1 acts as clock. EOR > Brains CLK.
Linear, R = 0, Fall = 14:30
Envelope controls VCA depth + VCO FM Index.
Maths Ch4 slews Press CV from PP buss (use input, not trigger).
R + F ca. 15:00, exponential.
Slewed CV > VCA (dynamics), Brains 'Run' + Maths Ch2.
Set Ch2 to ca. 22:00 (-ve) and patch to Ch1 Fall VC
Patch PP rows 1-3 > sequential switch. PP row 1 gate > A-152 clock.
Digital out 4 > reset, common I/O > quantiser > VCO.
And here's what's happening:
Although Maths is cycling and providing Brains with a clock, the sequence is blocked from running until the press CV exceeds 1V. On release of the touch plate, the Press CV fades out, allowing the sequence to continue running until it again falls below 1V. An inverted mult of the press CV, which is fed to Ch1's Fall VC via Ch2, controls the speed of the clock. The harder you press, the faster the clock. As the press CV fades, the clock slows. Try different rise and fall times for both channels 1 + 4 and the amount of fall VC from Ch2 to taste. You could, for example, have the sequence get faster as the volume fades. The remaining connections (Ch4 EOC > Brains reset, PP rows 1-3 > multiplexer etc.) are non-essential, but nice.
