This first idea was inspired by the MOOD pedal from Chase Bliss, Just a quick trick to get some strange randomish ambience out of a simple melodic synth line:
Isolate the melodic line on the tape track (Make it the only thing sending to the tape input) then set the timing for 2 or so, something short, put a trigger for the tape loop halfway through the sequence, holding till beat 13, then, And This Is The Important Thing, set the sequence length (Using track and shift) to 3 measures rather than 4. This results in the tape track mangling different chunks of the melody on each pass. Then you run Just The Tape Track through the delay (And reverb too if you’re feeling adventurous!), and adjust that to taste. Of course, all the variables can be adjusted to fit, the main point being to get the tape track running at a different interval than the melody so it grabs different chunks as it runs.
Another add on to this, is to increase the attack time on certain steps, and then use the spark component to say to the notes “Hey, you know that attack adjustment that makes the note sound reversed? Only do that sometimes at random.” Its the Parameter Spark set to 9 that will achieve that.
So, also, a second smaller tip for your randomized sequences (And this is a Staple, so you may have heard it before): Throw some delay on that sucker and listen as the sequence becomes instantly more musically relevant as the random sequences repeat themselves. Obviously you can use the automation of the delay track to make the delay heavier or less present as the loop goes along, and if you set the delay track for a 3 bar sequence as we did with the tape track in the first example, you get a nice sort-of-random ocurrance of delay.
Hope ya’ll have a lovely weekend.
