"quick demo to showcase the Zoom ER-200 analog BBD delay and spring reverb currently for sale.
Unit was slightly modded to double the original delay max time.
Synth used is the Realistic Concermate MG-1 by Moog"



via this Reverb listing

"rare made in Japan analog BBD and spring reverb. It was also sold as Deki or Cosmic AE-7000 and is quite similar to the Evans Echopet 250 / Rolling Rec 4.

The EQ (tone) is applied to the preamp too so can be used to shape the sound of the input source even without effect, and the delay sound passes through the reverb tank, so even when echo volume is down but if there are some repeats, the delay sound will pass throuhg the reverb. This can give some nice results.

Quite lo-fi sounding, bit noisy but great on synths, check the demo I made.

The unit was modded to double the max delay time.

Everything is working as it should. Input gain is quite sensitive, even in instrument input so you'd better lower the output volume of your source to get the best S/N ratio without clipping."

BOUCAN as Wavefolder & Waveshaper | Eurorack Demo Test


video upload by SOVAGE ENGINEERING

"A quick one-take video showing BOUCAN, being used as an odd wavefolder / waveshaper instead of its noise generator usual duties.
No editing, no cuts, just raw sound exploration.
If you like this format, let me know in the comments! It’ll motivate me to upgrade my video gear and make a lot more demos like that one with different modules."

Korg Wavestate | green hands on the soundpack "RELAXATION"


video upload by xu.sounddesign - dirk rohde

"Just playing with my soundpack RELAXATION for Korg Wavestate Mk1, Mk2 and Native VST.

No external effects were used in the demos. All effects are internal effects of the Wavestate. No other hardware was used. No compressor, no limiter, no equalizer, nothing, but the pure Wavestate.

No additional samples, but purely the factory samples were used.

I designed all the sounds myself. If you´re interested in my soundpacks, please send me an email (xu.sounddesign@gmx.net)."
