LEPLOOP V2

"Only a few of these were ever produced, hand made in Italy by engineer Tony Light.

This particular unit was made in 2013 and only used a handful of times. Everything is in perfect working order electronically and the case is in great condition. As it is handmade, you will see a small split in the bottom right corner of the wood case where the edges attach. It was like this when I originally bought the unit from Tony Light, so he sent me a replacement case if I was ever to need one, but the current one is sturdy and hasn't shown any signs of needing to be replaced. I am including the original unit, the replacement case, and the US power adapter in this auction. Due to the fragility of the item I am selling it as is.

This is a very unique sounding synth unlike anything else currently out there! It is also highly interesting for anyone involved in modular synthesis as it has many inputs and outputs for external signals. Just let me know if you have any questions - all specs are below:

DETAILS
The Leploop consists of two VCOs; the first with selectable wave form, the second with FM (source: VCO1, EG1 or LFO). Ringmodulation is possible, too. In the mixer section you can route and mix the oscillators. Of all sections the VCOs have the most modulation possibilites, even inverted envelope 1 or external CVs.
Further sound sources are a noise generator and the Cassa, a heavy bass drum with hard distortion, nasty distortion and attack. An external audio input is available, too.

Modulation sources: two attack-decay envelopes, a LFO with three wave forms, a flexible sample & hold generator and the sequencer. These can be routed by switches to almost all sections.
The sequencer has four tracks, memory and adjustable sequence length, depending on the number of tracks.

The filter is a resonant 24dB lowpass with modulation of cutoff and resonance. The input can be noise, the oscillator mix, the cassa or the external signal.
VCA1 is modulated either by the LFO, the 1st envelope or the S&H. noise, VCO1 or VCO2 can be used as audio sources.
VCA2 is modulated by the 2nd envelope only and it's input can be the filtered signal or the first VCO.

The final mix of Cassa, the 1st and 2nd VCA and the filter is set in a separate section.

CONNECTORS
S&H outputs: CV and Gate
sequencer outputs: CV and gate
LFO out, Cassa gate out, clock out
VCO2 and oscillator mix (3.5mm outputs)
CV inputs for both oscillators
CV outs for both AD-envelopes
external audio input
MIDI Input (5 pin DIN socket)
Audio output, Cassa individual output (1/4" sockets)"

"One off opportunity - Crumar Unique DBM BIT MIDI master keyboard for sale

Crumar keyboards were only around for a short period and this one boasts a very solid all steel construction (looks very similar to the Crumar Bit One). A 72 note weighted keyboard!, 3 way keyboard split with overlap and a nostalgic 4000 note 4 track sequencer built in.
The keyboard is great being 72 note, a must for a controller in my opinion.

LOOKS LIKE NEW, WORKS PERFECTLY ONLY THE ODD VERY MINOR MARK ON IT, collectors condition, would have said nearly mint, looks like just been brought out of a shop amazing condition considering its 30 years old.

This has a number of midi sockets and a four track sequencer which is the first time I have ever seen that in a midi controller - I did a video of it to show you how easily the sequencer is to use, it also stores songs you save after powerdown, all buttons and keys work like new, the synth is a collectors vintage item, remarkable condition weighs a lot so collection preferred but it will be packaged extremely well for full protection to survive a fall from a 4 story building, will be sent by reputable courier fully tracked and recorded from me to you insurance can be bought at additional cost after sale.

KORG mini 700

via this auction

" Hi. This is my beloved old Korg mini-700 synth. I bought it secondhand about 30 years ago.

This synth was bought by my mate from someone in a Melbourne band (neither of us can remember which band it was, but I've got it feeling it might've been 'The Primitive Calculators'). He also used it in the seminal Melbourne '80s electro outfit The Metronomes. I bought it off him.

I've never gigged with it myself (I'm a singer who dabbles amateurishly with a range of instruments), but it did get used in a Beach Boys tribute band I was in for a while, about 5 years ago (basically for an imitation theremin sound, I think). I haven't even turned it on since then, to tell the truth.

I plugged it in and checked a few things while photographing it. Everything seems fine. Love those sounds."

Rob Hordijk's BENJOLIN - EXAGONAL STUDIOS CUSTOM

Published on Feb 21, 2015 Nicola Locci

"The Benjolin is a analog, complex sound generator designed by synth pioneer Rob Hordijk.

'The Benjolin is a ‘noise box’ that is ‘bent by design’, meaning that it always has a definite amount of unpredictability while it is still intuitive to play. The Benjolin features two eighteen-octave range voltage controlled oscillators that drive a ‘rungler’ circuit, circuitry that in essence uses a special interference technique feeding back into the oscillators to force them into wild chaotic behaviour.
A special slightly chaotic filter is both excited and modulated by the signals from the rungler circuitry processes, producing sounds between fat drones to grungy noise havoc.'

The container of this version is designed by
EXAGONAL STUDIOS and is powered by two 9 V batteries.
