This is the prototype of a gunk repeater, i.e. a live performance instrument
for gunk music. Gunk music is approximately something like a meditative
variant of tekkno trance. (Some gunk music with explanation can be downloaded
The term "tekknetion" is an acronym that lives somewhere among "tekkno",
"cybernetics" and "accordion". The instrument of that name repeats multiple
(here up to 4) samples in loops and automatically synchronizes them to
an internal optical metronome (the pattern oscillator) to create rhythmic
patterns in a drum- computer- like way. By singing into a microphone, samples
can be generated and looped in realtime, while the others continue playing.
Each of the 4 channels can hold 1 short sample that can be either started
manually or continuously re-started (looped) by the pattern oscillator.
Also the volume and sample frequency of each channel can be changed in
realtime. All functions are accessible by OBS controls. Also the actually
played sound from the other channels can be re-sampled (through the microphone)
in realtime and then e.g. frequency shifted (scratched), which results
often in very chaotic, but gunky sounds (similar like tribal rhythms).
am not sure how far the way this instrument behaves matches the definition
of a "phrase sampler" (which also seems to be a live performance sampling
instrument). I much later also read about an expensive instrument of the
name "Repeater" by Electrix, which also seems to have a very similar
concept like my device.
Due to this tekknetion is just a simple, mainly analogue prototype, it can not save any samples nor patterns for later re-use, but only hold those up to 4 samples it is currently playing. Also the samples are very short and lo-fi and have only 6 bit resolution at a few kHz (depending on the selected sampling frequency). Though basically the sound and concept of this instrument is not more than "circuit bending to the extreme".
A nasty flaw is that the record button must be pressed a moment (e.g. 0.25s) before recording a sample (the exact time depends on selected sample frequency), otherwise the begin will be missing. The button also needs to be pressed a little longer than the sample, otherwise the end will be missing. This makes the use of the instrument prototype way less intuitive.
The samples also start and end with a quiet click; initially the click was even a loud pop because the battery saving transistor only supplied the module's small power amp IC with voltage so long a sample was played, though I re-wired this amp for direct supply and the pop was gone.
Generally this instrument is much fun to experiment with and it can
make a lot of surprising and gunky sounds, but it behaves often little
predictable and to get a desired result out of it is rather difficult.
(But possibly the same sentence could also be spoken by anyone who tries
out a violin and hasn't trained hard to play it. ;-) )
I yet didn't play the tekknetion often, but I plan to use this as the basis
for a (better sounding) software version for PCs.
