A basic mono synth built around a Ramp function and a glitchy Scrambler, it’s Rambler!

I’ve had my Organelle 3 days, this is my first PD patch!

Rambler is a basic single oscillator mono synth taking input from the Organelle keyboard.

When a note is received from the keyboard, Rambler starts a ramp up to full level and then ramps back down to zero. This gives a basic fade in/out from a single keypress.

Knob1 controls the total length of the ramp up/down operation in milliseconds. The range is 1,000ms to 20,000ms.

Knob2 is the octave for keyboard input. 0 = standard pitch, -12 drops it an octave, -24 drops 2 octaves. Turning knob2 all the way to the left will give -24, all the way to the right is 0 and -12 happens somewhere in between the two. Essentially 3 positions.

Knob 3 controls the rate of the scrambler component by changing the rate of a metronome outputting regular bangs. These bangs trigger a random velocity modifier that takes the oscillator signal and attenuates it so with each bang you end up with a signal that is either unaffected or attenuated by a random amount. This happens at an interval set by the scrambler rate in milliseconds.

Knob 4 controls the amount of scrambler signal, ranging from 0% to 100%. 0% is all clean signal with no scrambler, 100% is just scrambler and no clean signal.

Finally there is a simple 10s delay with 5 not-quite-evenly-spaced repeats bouncing from left to right channels and a basic display on line 5 showing progress through the current note’s ramping envelope.
