Been a few days since the previous Buddha Machine Variation. The camera died, after it had stopped playing nice with audio. And I got a new, smaller synthesizer case (from Pulp Logic, who were super helpful with plotting it out). This is the first time I’ve ever used an expression pedal with my synth, thanks to one of the three tiles in the upper left corner of the box. (“Tiles” being a term for the shorter modules seen top and bottom here, above and below the ER-301 module.) Very simple little patch. Just a proof of concept. The tiny foot (well, hand) pedal is triggering the recording of a microloop (400 or so milliseconds) of the choral audio coming from the Philip Glass 80th-birthday edition of the Buddha Machine. The expression pedal is varying how much we’re hearing the inbound Glass loop, and how much we’re hearing the microloop. If you’re wondering where the Buddha Machine is sending its audio into the synth, there are jacks in the side of the case itself.
For further patch-documentation purposes, here are two shots of the synthesizer:
This was an experiment in exploring the device as a whole: not just as a set of loops contained in one object, but the sequence of those loops, and the way the loops progress as a result of the object’s design. All the previous Buddha Machine Variations to date have involved one loop per machine. Here the multiple loops of such a device, one from the second-generation of Buddha Machines, are heard not just in sequence, but in overlapping sequences. They’re considered as a suite.
There are three subsets of whatever loop is playing at a given time. Each is a subloop: one three seconds, one four seconds, one five (in the ER-301 module, using the Feedback Looper unit). Each of the subloops is extracted from a different narrow band of the audio spectrum (via the FDXf module). As the piece proceeds, the button on the side of the Buddha Machine is clicked. One or more of the subloops begins recording the new audio almost immediately, but there is some time before the preceding loop is entirely eradicated. At the very end, the audio cable is pulled out of the Buddha Machine, and eventually all the subloops give way to silence. (This was less sudden when rehearsed, but it works OK here. I’ll be trying this all again with a slightly different approach.)
For further patch-documentation purposes, here is a shot of the synthesizer:
One loop from the fifth generation Buddha Machine, little snatches of it glitching out in a semblance of correlation. At first all that’s heard is the unaltered audio of the source loop. That’s the fifth channel of the mixer (lavender cable). And then one by one, the first through fourth channels of the mixer are introduced. Each is set on a mico-looping procedure of the source loop, varying individually between roughly 100 and 300 milliseconds. They are each set to record over whatever was there before, meaning sometimes there will be silences. And finally, once the main source audio is turned off in the mix (at 1:45), all that is heard is this combination of microloops.
If you’re familiar with the ER-301 module, here’s some additional detail: The unit being used is the Feedback Looper. There are four of these running individually. Each is taking a square wave from the Batumi as its on/off switch to record. In addition, each is taking the next channel’s on/off as its trigger to (un)engage (the fourth channel looks to the first channel, squaring the circle).
That runs for quite awhile, and then at 2:55 the relative pace of the four square waves are altered. This has an impact on when the individual loopers are triggered, and then at 3:09 the Batumi is switched from “free” mode to “quad,” and the levers adjusted further.
For further patch-documentation purposes, here is a shot of the synthesizer:
One loop from the first generation of the Buddha Machine, which turns 15 years old in 2020. The loop ends up with three variants in the mixer, channels one, two, and five. The fifth channel (lavender cable) is just the straight audio out of the Buddha Machine (a little noisier than usual, perhaps because the batteries were going). The first channel is the output of the Muxlicer, which switches between eight variants on the audio: six are spectral bands (from the FXDf), and two are channels of the granular synth (the position of which, in the Smog, is shifting regularly). The Muxlicer is going at a steady pace (clocked by the Dixie II, starting when the Muxlicer’s switch is flipped at :28), but the sequence is random thanks to an inbound sine wave (from the Batumi). The second channel, which kicks in at 3:24, is a tiny fragment of a loop that is constantly being overwritten, and it’s set off from the Muxlicer’s beat by a slight, almost half-second delay, which at first gives the contrast a sing-song quality, but eventually disappears as the amassed swell occludes virtually everything. And that’s about it, except that at 4:25 a slow wave is introduced to gently alter the volume of the original, channel-five track.
For further patch-documentation purposes, here two shots of the synthesizer:
This is a Saturday evening trial run at selecting tiny bits of a single loop from a Buddha Machine and having them pulse against each other. Eventually the main source line is eliminated so that only these microloops remain. Toward the end, two of the microloops are further affected by delays that warble by changing ever so slightly within a narrow range at a rapid pace. There’s not much more to it than that. The source audio is the third generation of Buddha Machine, called Chan Fang, which came out a decade ago, back in 2010. The instrument heard is the qin, a Chinese zither.
There are five channels into the mixer. The purple one, channel five, is the unadulterated source audio. Channels one through four each get their own individual micoloop in real time, one at a time. Channels three and four are the ones eventually set to warble (channel four starting at 3:24, channel three at 4:52). The loops and delays occur in the ER-301 (the large synthesizer module in the lower left, running the Pedal Looper and Delay units). The warble is a result of a pair of waves that come from a combination of the Batumi (the one with four vertical levers directly above the ER-301) and the S.P.O. (the one with four black knobs, two to the right of the Batumi). I’m going to explore this approach further, likely combining microloops from various loops of the Chan Fang.
