Kawai K3: favorite sounds

video upload by Najvrtson

"Most of these sounds were created by me, but honestly I forgot which ones... Kawai K3 is an excellent sounding digital-analog hybrid synthesizer. If you have an opportunity to acquire one, do not wait!"

Tiracon 6V + Vermona Synthesizer + Vermona SK 86

video by Najvrtson

"Three wonders from East Germany, three keyboard instruments unique in their era: The only monophonic synthesizer, the only polyphonic synthesizer and the only arranger keyboard made in GDR together in one a little bit strange composition! This composition has been already used in my older video, but then I played it on Electronica EM-25, Delicia HT-61-BD and Vermona SK-86 (you can watch and listen here:)"

Vintage Analog Synthesizer RMIF Opus: Sound Demo

Published on Feb 28, 2017 Najvrtson

Here's something most have likely never seen before, a vintage soviet RMIF Opus. I believe this is the first one to be featured here.

"The tune (russian folk song Polyushka Polye - despite the fact, that the instrument was made in Riga, Latvia) was entirely recorded on RMIF Opus, except of drums (JVC KB-700) and some reverb and delay effects. Opus was made cca in 1988, but technically wise it was obsolete at the time. It is based on divide-down technology, but has very nice filter (LPF, BPF and HPF with resonance), excellent chorus unit, ring modulator and some other fine features. Enjoy its sound!"

Vintage Synthesizer 3-83 UNISONO from Czechoslovakia

Published on Jun 5, 2012 Najvrtson

"This is a short video showing the sound possibilities of Synthesizer 3-83 Unisono - a very rare monophonic synthesizer made in Czechoslovakia in first half of eighties. The synthesizer has an unusual design with two VCO's, VCF one and one VCA with limited edit possibilities. The audio track was recorded by Jiri Krivka and given to me by Moimir Papalescu, the photo of the instrument was taken by Ivan Hirländer. My big thank to them!

YAMAHA EX-7 Sound Demo

Uploaded on May 8, 2010 Najvrtson

"Here I recorded a short demo as a homage to Yamaha's EX-Series synthesizer workstations. I use it more than five years for each performance on the stage. EX-7 is my favorite instrument for (not only) syntesizers, el. pianos, organs and guitar sounds."

GEM (Generalmusic) S - Series workstation - sound demo

Uploaded on Apr 23, 2010 Najvrtson

"A short sound demo of this excellent Italian synthesizer workstation. This demo is actually played on GEM S2R rackmount version, but the sounds were mostly created on my previous GEM S2 Turbo, which I unfortunately sold. Actually I have found one S3 Turbo and I'm planning to record a second demo."

"Just a few textures from preset mixes of Alesis QS6.1 synthesizer... The sound is unfortunately compresed due to mp3 format, the original is much more deep and clear."

Solton K160 Sound Demo

YouTube Uploaded by Najvrtson on Mar 27, 2011

"Solton K160 was made by Ketron Laboratories in Italy, sold under the name of company Solton and finally, in Czechoslovakia was sold as Delicia Solton K160 with power adaptor and soft case made in Czechoslovakia. This instrument is almost forgotten now, so I decided to buy one and to make this sound demo. K160 was cheap 8-voice polyphonic preset synthesizer with analog filters (CEM3389). There are only very limited possibilities to modify the sound. All sounds presented here are factory presets as they are coming from the instrument. I only added the reverb to the pipe organ sound.
