I built this fantastic machine a couple of months ago to add to the 2 original Wasps I have and help me rebuild them. Jasper is a high quality instrument in comparison to the questionable quality of the original Wasp. Take a look at the Jaspersynth website for further information. I bought the really nice case made by Clockout which you can see in the last photograph. An external power supply is included and I will also include the unused parts should you wish to add the battery power option.Details from Jaspersynth website.Jasper is a clone of the Wasp synthesizer that was made by the small British company EDP (Electronic Dream Plant) for a few years from 1978 to 1982.The Wasp was one of the first commercially available digital/analogue hybrid synthesizers. Designed by Chris Huggett and Adrian Wagner who created it as an affordable synthesizer using the then newly and widely available inexpensive CMOS digital logic chips. Jasper retains the features and controls of the Wasp, including the touch keyboard, and the Link port to allow digital connection between similar equipment. It also adds a few extra features while retaining the essential nature of the original. Jasper is fitted in a very professional metal case with oak side cheeks. Jasper shares all the main features with the original Wasp:Two digitally controlled oscillators (DCOs) with pulse and ramp waveforms.Digital pseudo-random white noise sourceLow frequency oscillator (LFO) for control (about 0.55Hz to 100Hz)Voltage controlled filter (VCF)Voltage controlled amplifier (VCA)Two envelope generators for controlling the filter and VCATwo octave capacitative touch keyboardHeadphone and line out portsBuilt-in speaker amplifier to power an 8ohm speakerLink port to connect to other Jaspers (Wasps, Gnats or Spiders)Battery power optionalExtra features in JasperJasper has a few extra features not on the original Wasp synthesizer:Mix level control for each oscillator similar to Wasp DeluxeAudio input, with variable gain. This can be mixed with the oscillators or noise source (the Wasp Deluxe had external input, but this apparently was wired directly to the oscillator switches meaning you had to switch out an oscillator if you wanted to process external audio).Enhanced waveform for each oscillator. These are pulse width modulated square waves, controlled by simple fixed 0.3Hz LFOs the same as implemented on the Gnats single oscillator. This enhanced wave is available on the oscillator waveform switches, expanding the available palette of sound. Notch filter mode, in addition to low, high and band pass filtering. The low-pass and high-pass filter signals are mixed cutting out the signal at the filter frequency.Envelope hold switch. Two variants are available, which can be selected using a DPDT on-off-on switch. The first holds the envelope open as if holding down a key; the second prevents the envelope from decaying. Useful for making drones or setting up sounds. The first version of Jasper only allowed for the second hold variant.External envelope trigger mod. This allows for a switched jack socket to enable external triggering of the envelope, useful for synchronising Jasper with external equipment.Low dropout voltage regulator for longer operating time on batteries.Power LED to show when the synth is switched on.MIDI interface fitted so that the Jasper can be played via MIDI. Note that you can play nearly 3 Octaves (C0# to C3) over MIDI but limited to 2 octaves on the keyboard.Additional 1/4″ output jack fitted at rear to supplement the 3.5mm jack on the side
If you Google Jasper synth there is additional information available plus some good videos on YouTube. I am not going to let this go for a low price, I would rather keep it so sensible bids please.
I’m happy to ship outside of UK but shipping cost will need to be confirmed.
