Buddha Machine Variations No. 24 (Shudder Valve)

A series of focused experiments

The goal here was to push the Muxlicer by altering its clock as time passes. The clock is what sets the pace of the changes that you hear. The Muxlicer, from the manufacturer Befaco, is the module toward the upper right corner. It’s the one with all those red faders that go up and down. The way the Muxlicer works (in this scenario, for there are various others) is you put in one master audio line that is then spread across the eight stages, the relative volume of which are individually set according to those faders. And then you can slot in alternate audio in as many of those eight stages as you like. So, as the clock clicks through its paces, you hear each of the eight stages in sequence, with the alternate audio occasionally replacing the main audio, and the volume of each stage shifting as well.

I’ll get to the source audio itself in a moment, but first about that clock situation. Initially while patching this, I just had a steady clock coming from a trigger pulse from the Dixie II (manufactured by Intellijel). If you want to know what the Muxlicer’s clock pulse is, keep an eye on the rate of the little light toward the top of the Dixie II, which is the seventh module in from the left on the top row. To give the steady pace some vibrancy, I had another wave, a sine from the Batumi (from the manufacturer Xaoc), create a random-ish, ever-shifting sequence as to which of the eight Muxlicer outs would play at any given moment. So far, so good.

But I wanted to push the clock further. This effort came in two phases of the patch’s development. The next thing I did was feed a slow moving square wave from the Batumi into the pitch control of the Dixie II. This meant every time the Batumi wave was on, the pitch of the Dixie II would suddenly level up, meaning the clock signal sent to the Muxlicer would speed up. This worked well, but an interesting thing happened. Since the square wave initiated this change in regular increments, going back and forth, the change in speed of the Muxlicer fairly quickly came to feel rote. If, as Brian Eno said, repetition is a form of change, then this was an example of how change (the clock going from fast to slow to fast, round and round) became a form of repetition. Something needed to change, in other words, for this to feel less repetitive. Something else needed to make that change occur.

I should note that the square wave going into the pitch of the Dixie II is squashed in height a bit by the S.P.O., from the company Steady State Fate. Initially this decision was made in order for the change in clock pacing to not be too significant. But then something occurred to me: the S.P.O. can combine signals, so I put a second, more chaotic wave also into the S.P.O., meaning that every once in a while, the square wave affecting the speed of the clock out of the Dixie II would itself be altered with a rapid little uptick. As a result, the change in the rhythm evidenced by the Muxlicer became more complex. If you keep an eye on the Muxlicer, there are eight horizontal red lights just below the faders. Watch those, and you’ll see how the clock changes. Where that additional, chaotic wave form comes from is it’s an envelope from the Detect-Rx, which is following the volume of one of the bands coming out of the filter bank. Which is to say, there’s some chaos going into the clock, but at some level it is correlated with the sound of a Buddha Machine itself

There’s more going on regarding the audio inputs. The blue one is first generation, and the peculiar color is second generation. The blue one (with the green audio cable) is split, and half the signal goes into a filter bank while the other half goes into a granular synthesizer. Three bands come out of the filter bank. One goes into the main Muxlicer in, one into an alt-in, and one into an envelope follower (more later). The left channel of the output of the granular synthesizer also goes into the Muxlicer alts (twice). The right channel of the granular synthesizer goes into a second channel of the mixer. Its volume is then altered thanks to a square wave coming out of the Batumi. However, I wanted to find a complement to the sudden jerks (the shudder) of the clock, so I put a burst-like signal into the trigger of the granular synth. The signal is a square wave, the frequency of which is being altered by a different square wave, the frequency of which is itself being altered by a sine wave (all within the Batumi; I believe this is referred to as self-patching). If you look at the lights of the four red faders of the Batumi (fourth module in from the upper left), you’ll see when that rapid burst kicks in. And, of course, you’ll hear it.

Which leaves a question: where’s the second-generation Buddha Machine? It’s not heard here. A patch starts in one place, and ends in another. At some point I disconnected the second Buddha , was pleased with the result, and never patched it back in. I didn’t fully recognize this until I was done.

For further patch-documentation purposes, here’s a straight-on shot of the synthesizer:

Buddha Machine Variations No. 23 (Voltage Redress)

A series of focused experiments

The batteries were dying on one of the Buddha Machines, so I recharged them. But only a bit. Just enough to let them last for this recording. The green one on the left is the one giving out the dying-whale sounds, the dying Buddha. The blue one is fully charged. Both are sending loops of drones into the synthesizer.

There are only two channels into the mixer at the end of the line. One of them is straightforward, the second of the two. It is passing a tiny bit of sampled audio that changes every so often. That audio being sampled and looped is a snatch of one band of the blue Buddha Machine; that’s after it’s been extracted from the broader audio spectrum. The playing of the loop is being triggered by a square wave from the same module that is providing the overall clock for the rhythm heard. The moment at which the sample occurs, however, is triggered due to another square wave, which is moving at a slower pace. That’s channel two.

Channel one is built around the Muxlicer from the manufacturer Befaco. This is the first Buddha Machine Variation to include the Muxlicer. (All the other modules have been used in previous variations, so I’m not mentioning them in detail here.) The Muxlicer does many things. What it’s doing here is as follows. It has one main input, which received the direct line of the “dying Buddha,” the green one. There are eight “outs” from the Muxclicer. The dying Buddha is the default audio for each, its volume altering based on those eight faders. However, four of the tracks have alternate inputs, which override the dying Buddha. Of these alternate inputs, the first is a copy of the blue Buddha. The third, fifth, and sixth are all bands extracted from the blue Buddha. And on top of all that, the sequence of which of the eight outs is playing at any given time changes continuously, because they’re being randomly assigned by a sine wave that’s not sync’d to anything else. Sometimes the same out even plays twice in a row.

Buddha Machine Variations No. 22 (Glitch Cycle)

A series of focused experiments

One Buddha Machine, first generation, one loop. It’s split into three strands. One strand goes straight into the mixer. That’s channel one. One strand goes into the low-fidelity looper, which spits out little instant-recall snippets into the filter, which then sends three bands of audio spectrum to the mixer. Those bands are channels two, three, and four. And the third strand goes into the granular synthesizer, which yields channel five.

The first and second of those mixer channels, in turn, have their audio impacted by slow-ish waves (slowish to the extent that they’re not themselves audible): the second by a square wave; the first by a square wave that is, at heart, sync’d to the first, but is then delayed a smidgen. The brokenness of the overall beat comes from the combination of that delay and the underlying tiny loop.

All these modules have been used in recent patches in this variations series, with one exception: the looper, which is the UL1uloop from soundmachines.

Buddha Machine Variations No. 21 (Dark Pixels)

A series of focused experiments

This variation on a loop from the first generation of the Buddha Machine was as much a test for the AV Squad as it was for the Music Department. I’m trying out a new camera, and the good news is the audio sounds good (as with yesterday’s, the audio was recorded straight to the camera, rather than with the device’s built-in microphone). Clearly I need to get a better viewing angle (at least it isn’t all fish eye like yesterday), and better light, but sound-wise it’s a step forward. And sound is the point.

As for the patch, the loop is heard in five simultaneous modes, left to right in the mixer. Leftmost is the raw audio, and next to that is audio out of the granular synthesizer. Both are having their relative volumes tweaked by sine waves pulsing in sequence. More on those in a moment. The third, fourth, and fifth of the mixer’s channels are all bands of the audio spectrum from the original signal.

The volume of the first and second channel are being raised and lowered in accordance with the relation between the three pulsing waves (the “and” and “or” paths in the Cold Mac module from Whimsical Raps). It’s more subtle than I’d hoped for, because there’s little if any overlap to build on, and I’ll work on that in the future. The third and fourth channels are the main place that pulsing comes from. A square wave at the start of the rotating sequence of pulses is triggering one, and then a gate delay (in the Ornament and Crime module, running Hemisphere) is pushing the other back a moment. In addition, the trigger on the granular synthesizer is receiving a trigger pulse from a square wave at the end of the four-pulse sequence. (I’m not listing the devices in detail because they’re the same ones I’ve mentioned here in recent projects.)

Buddha Machine Variations No. 20 (Pattern Cognition)

A series of focused experiments

This is a short one, and a change of approach. It’s a test run, really. (Every entry is an experiment of some sort.) Samples extracted from three different loops of the first-generation Buddha Machine, which dates from 2005, were recorded on the Teenage Engineering PO-33 K.O! and then run as a series of patterns, the patterns chained into a sequence. The samples are tuned. Audio goes out to a GoPro, via a Zoom H4n. That about covers it. The Buddha Machine shown here was the source of the samples, but it’s displayed for decoration only, since the sampling occurred prior to the video being shot.
