Sequence 152 by and per se and published on 2014/02/12 09:34:12 +0000 Creating two longer and more varied sequences from a couple of short sequences, using the Doepfer A152. Two 8-note sequences go into A152 switch inputs 1 and 3, and are multed to 2 and 4, while the 5th digital out goes into the reset in. When clocked at 1/8 the rate of the input sequences, the A152 thus creates a simple 4 bar ABAB meta-sequence, which goes to one channel fo the A156 for quantisation. To make this more interesting, the 4th digital out goes through an attenuator to the A156 Transpose in, so the bar structure now goes ABAC. The amount of transposition wasn't what I intended it to be, but in the end I liked the chord change, which reminds me of Philip Glass or "Music for the Masses"-era Depeche Mode. A happy accident. The quanitised CV then goes to a Dixie II, whose triangle goes into Optomix, which is struck by a uScale pattern. For further variation, the 3rd A152 gate out goes to the Optomix Control in, changing the dynamics on the third bar. That's the blippy melody that runs through most of the track. To create the bassline, the first sequence goes to the A152 T&H common input, and the 1st and 3rd T&H outputs go through a mixer into the second channel of the A156. The bassline thus follows the melody on the 1st and third bars (though the mixer settings attenuate the sequence CVs to get a different series of notes), but gets held at the last note of those bars through the 2nd and 4th bars. Actually, the fact that I use a mixer rather than a switch means that the last held notes are probably transposing the other bits of the sequence, but I haven't investigated further. The quantised CV then controls a Rubicon with variable PWM, the output of which goes into the second Optomix channel with the Control slightly open to give long held notes rather than just plucks. I still haven't truly figured out the T&H column of the A152, but this is an example of using all three columns to get a range of sequences and variations out of relatively simple inputs.
