Note the date of the video. The video was just linked in the auction for demo purposes and is not the one for sale. The following is from the description: "The build quality of the Syndrum is typically seventies American ( moog Arp) but seems to do all that's needed occasionally you get a sticky slider or switch but most of us can deal with that if you want to fully restore it is is thankfully fully discreet circuitry and all parts are available i haven used the pads ( loom is included ) i was triggering this from voltage triggers or sound sources i don't think the 4 pads are working properly but its probably only a minor issue with leads or connections it has been describes as 4 Moogs in a box? http://electro-music.com/forum/post-15480.html i can tell you it has a very wide range of sounds and extremely wide range LFOs at times it can get out of control but if you can control it then huge subsonic kicks . crispy snares and melodic toms toms are all there all 4 voices are identical this has a far wider range of sounds than other electro drums of the late seventies ( like Simmons SDS5 - i have owned all of them at some stage ) the book had not been written yet and rules were broken"
"Works great with something like a Behringer BCR2000 [or iPad]. New memory back-up battery. Some power supply improvements that are detailed in the schematic, but missing from this example when I got it. 2 New Voice IC's(£15 each)"
"There are 7 controls on one side Decay, Sweep, Pitch, Balance, Noise Filter, Bite and Output Level. It takes a PP3, 9 volt battery. It has a XRL connector"
