Muff's:
"we (Roman Filippov and Alex Pleninger) are glad to introduce the result of almost a year of development, coding, electronic tests and just complex work in general - Sputnik Defect Processor Model 289.
this device is crafted to precisely comply the modular standards of Buchla Electric Music Box better known as Buchla 200 and Buchla 200e.
the core of the 289 is a Digital Signal Processor which takes all the computations in sound transforming and generating. around it one may observe some controllable analogue parameters such as Balance and Regeneration, they are independent for each audio channel. both DSP cores have 8 independent Programs or Algorithms per core and each such algorithm has three voltage controllable parameters, varying from program to program. each core can be expanded via another 8 programs on external EEPROM chip. one of the most exciting feature is the variable Timebase which affects a lot of nuances in every algorithm's behavior.
apart from conventional stuff like reverbs, delays and various modulations the Model 289 offers quite unique solutions such as fm-synthesis, wide sonic range generators, human throat modelling, simple spectrum transfer facility, pitch-to-cv conversion, pitch shifting, audio looping, several sound destructors, pitch class generator, karplus-strong synthesis and many others, including some auxiliary programs. and the program list is ever-growing, new programs are always on the way.
we hope this module will take its place in every Buchla system whether it is a baby 4U boat or two 18U cabinets mighty electronic workbench.
ALGORITHMS
OSCILLATORS
we offer two oscillator programs, both of them work in audio range from 25 to approximately 3000 hz.
the controls are the following:
x - pitch.
y - wavemorphing.
z - wavefolding.
audio inputs 1 and 2 support amplitude and frequency modulations respectively.
on the output 1 you'll get final waveform morphed and folded, if any.
the second output provides the sub-oscillator one octave below the main one.
as for y and z controls, the first one continuously morphs the osc core (saw or triangle, depending on chosen program) from saw through triangle to half-inverted saw or from triangle through sine to square. in the case the wavemorphing is set to square, the wavefolding performs as pwm controller. in any other situations z-pot folds the wave in a manner of mathematical reflection at the given threshold. all these are pretty straight-forward, even if sounds a bit messy. you may observe the oscillators behavior in the attached [above] video footages.
