V.A.I. 73 : Antonelli Syntorgan 2445 / FBT R-21 Leslie Simulator

video upload by Vintage Audio Institute Italia

"Antonelli Syntorgan 2445.
Lovely and quirky machine with a mono synth and high / low pass filter controls.
It came with legs, preset overlays for a handful of sounds, and a songbook.
There’s a very simple drum machine and auto bass/chords on board as well.
The Antonelli Syntorgan 2445 is actually fun to play and compose with, the two filter types really save this toy keyboard and elevates it beyond Bontempi standards.
Marketed for beginners and kids, it was apparently manufactured by Siel - it’s basically a slimmed down and tinny sounding Siel Cruise : a mono section and a poly section.
On the Syntorgan you can route the poly section through the mono filter, plus it has a kind of hidden two octave bass preset, a drum machine and auto-bass and auto-chord section too.
We used some external effects, this machine really needs it :
the Tekson Fading pedal for phasing the drums, then an odd and crazy rare FBT Dual Channel Equalizer rack-unit for some color, and a Montarbo Analog Delay (actually digital) with a broken chip that somehow distorts things wonderfully.
On some sounds we also pulled out our FBT R-21 Leslie simulator, an optical rack device based around a spinning disc, it looks almost like a tape echo.
