Wersi CX-1 based 19" midi drum expander

Published on Mar 1, 2020 Stereoping

"Test- and demosong for a little DIY project - an analogue rack #midi drum expander based on some soundcards of the #Wersi #Wersimatic #CX-1. Together the 3 PCBs supply 14 different sounds, some quite interesting. One is called "Synthedrum", an oscillator with 3080 VCA allowing several interesting mods, they are demoed at 1:20. The video also shows some pictures of the building process. All drums in the song - except the tabla - coming from this unit. Other gear: #Waldorf #Pulse, Deep Bass 9, Roland #Integra7, #Boehm Dynamic 12/24 and a beautiful Flute from the #Akai #S900 through a Roland #DEP-5."

"I had the opportunity to take care for this magnificent peice of instrument for while. tI has been one of biggest dreams to own one since i was a boy with toys. Now that I tested it for some time i can say that for the price, I'd rather go for the Moog One. Sure, I still want one but only, more or less, as a collectors item. But It can still perform and make sounds like no other."

"This synth is in incredible condition for its age, it has been very well cared for and has never left my studio as long as I’ve had it. There are no issues whatsoever with the synth everything functions perfectly as it should and it sounds incredible. It hurts me to have to let it go but I’ve moved into a smaller studio and no longer have room for all of my full keyboard synths :( I have shipped quite a few vintage synths with no issues but I will be purchasing Reverb’s shipping protection just to be safe. Rest assured it will be packaged extremely well. This is a beautifully preserved piece of Roland’s history. Fast, free shipping!!"

Best Ambient Synth Shootout #81: Böhm Dynamic 4x9 - Song 2

Published on Mar 1, 2020 Christian's Sonic Spaces

"This is the second song with the Boehm Dynamic 4x9. It's a German FM-synthesizer from mid-80s that were only available as DIY project. It uses 12(!) Yamaha ICs of the type YM2203, which were commonly used in home computers from NEC as well as in arcade games until the early 90s. Each of the ICs has 3 FM-voices for an overall 36 voices 4-part polyphony.

I used for the recording the following FX for the song:

T-Rex Twister, DigiTech Obscura, Alesis Ampliton, Pigtronix Echolution 2 Deluxe, GFI System Specular Reverb 2.

Depending on the recorded track some FX are deactivated.The signal went through a Presonus StudioLive 16.0.2 into the PC for recording. To create the complete song I recorded consecutively several stereo tracks. The final song was then mastered with a bit EQ and compression on some tracks and some limiting on the master track."
