"great and very rare semi-modular synth hand made produced in 2009/2011
VolFram is semi-modular noise synthesizer and fx-proccesor based on digital 8-bit echo chip Ht-8970
it can be used as flexible delay/reverb processor, fuzz and complex. All these fx-capabilitys can be mixed and controlled with much flexibility
Only 56 unit were made
It has a very rare Dimitri's modification: very usefull sensitive knob on the right (see pic)
Great for noise/experimental synth, released a few years ago for a specific art project by Russian genious artist ::Vtol:: aka Dmitriy Morozov.
Part of a set of other semi modular machines, it is a stand alone dekstop device that offers different frequencies, from nasty high-pitched noise, to throbbing medium basses. Suggested for artists working with industrial, noise, power electronics, drone, and experimental.
A great piece of artisanship that I didn't use much but was worth the money. released in 55 models
fx-proccesor based on digital 8-bit echo chip Ht-8970.
Needs a BOSS type 9- power supply
demos on line are not as exciting as the machine really does great potential."
