32. Dream Machine

2012-04-29-IMG_1694.CR2 For producing simple rhythmic patterns with long pauses in between.

Based on binary counter and multiplexer, Dream Machine has 8 outputs and a combined output. At any time, exactly one output is active unless that output has been turned off with buttons in the front. Switching of outputs is controlled by external clock. There is also an auxiliary pulse input which can be turned on or off. When off, the whole sequence in controlled by the primary clock input. When on, control of one of the three bits that select output is transferred to the the auxiliary input.

A rotary switch on the panel allows for changing the sequence pattern. In basic mode, all outputs are cycled periodically, whereas other three modes give more complex pattern with various total lengths. With the rotary switch, different styles can be used select the total length of the pattern. Then the active outputs can be selected to fine-tune the pattern. If unpredictable or very long patterns are desired, the auxiliary input can be connected to complex output of some other sequencer.

31. Ericsson

2012-04-29-IMG_1691.CR2 An example of higher-order recycling, this instrument re-recycles casing and some parts from an older disassembled Koelse instrument. Probably whoever invented the word recycling was thinking of something like this when he put the 'cycle' in there.

Ericsson is a sequenced bank of four voltage controlled oscillators. Each oscillator has its own CV in channel. Sequencing the oscillators is controlled either by external clock input or internal voltage controlled clock. There are outputs for each oscillator separately and a combined output.

Due to serendipitous accident in circuit design, this sequencer is able to power itself from CV inputs. Irregularity of this kind of power supply also causes all kinds of interesting glitches, extending Ericsson's musical possibilities.

One important feature still in the to-do list is a pulse input for muting output. Until it is added, Ericsson is a bit too dominant to be used as a lead instrument, but works very well for generating low volume background soundscapes.

30. Jazz trash robot

2012-04-29-IMG_1716.CR2 Jazz trash robot is old concept, originally we developed it as a proposal for Artbots competition back in 2008. We wanted to challenge the robot concept, as something hightech and intelligent,  and push lo-tech low tech elektromechanic model throught..

They did not choose Jazz trash robot to the artbots, but it did appear in several of our own exhibitions and events.

 Original robot had massive amount of mechanical sequencers, some timers, oscillator, 24 in/24 out patchay and a keyboard that it was hardwired to play.

 Old description text I found says: "We designed this project originally to help us synchronize the equipment. Our aim was to get one step towards the discomusic from the complitely uncontrolled noise we usyally play. Well now that we started actually making this, it seems obvious that this device will make everything rather more complicated and less controllable, but if we are lucky it will play us some discomusic. Basically it is not an actual sequencer, but more like a mechanical signalcutting device. It has 24 inputs and 24 outputs. When you patch an instrument throught the device it will be cut in the sequenses determined by the mechanical sequencers. Our aim is also to build some kind of a robot, a system tha is complex enought to produce surpricing and rich soundscape. Connected with the rest of our experimental instruments it is supposed to form a selfsustaining soundproduction enviroment. "

So Jazz Trash Robot was an important step towards more seqenced, and organized form of producing sounds, even thought it did not help much in practice since it was rather chaotic and complicated machine.

Eventually it broke down and since it was a 230v device we had to rebuild it for for our exhibition in Pori.

Now Jazz Trash Robot has external sync, so it can be synchronized with other equipment.

Two 4014 8-bit shift registers used as two loadable sequencers. Two 4046 vcos, 4069 filters, simple diode vcas and a mixer made of some opamp found on the floor.

My First Sequencer, shortly MFS<3, is a 40106 osc, 4040 divider and 4051 multiplexer. It has a portable cassette player (with carcontroller as motor slowerer) as sound source, two mics for a proper rap battle and six steps. Aight.

I don’t even remember all that’s in here at least a 4522 divider and some other logic chips. LDR´s, leds etc. controlling oscs. Insane device, which sometimes seems to have a life of its own.
