JP6K is a synth dedicated to emulating the famous Super Saw sound, first found in the Roland JP-8000 synthesizer in 1997. It aims to capture the essence of the sound and the behavior of the original oscillator. Even after a decade, the Super Saw is still sought after by people all around the world, and is a crucial part of such music genres like Trance.

There are several factors that make the Super Saw in the JP6K different than other synths that provide a similar sound. The original Super Saw from Roland was aliasing, thus creating a bright and “airy” sound. To prevent the sound from sounding harsh below the fundamental harmonic, a high pass filter was possibly used to remove the unwanted frequencies. The JP6K uses the same design to achieve that special oscillator waveform giving it a unique tone.

Another important aspect of the classic Super Saw, was its special detune curve. It was non-linear, which gave the user greater control over the detune amount. Even when the detune control was half way, the spread of the detune was small, which made it possible to make very smooth sounding pads. The curve then gradually increased, and at higher values, the detune rapidly spread out to maximum. This unique curve is accurately modelled in JP6K, making it nearly identical to the detune in the hardware.

The JP6K also emulates other features from the JP-8000 like the filters, key tracking and the EQ, to give it an even more authentic way to shape the Super Saw sound. The synth has been optimised to use minimal amount of CPU, so it is possible to use multiple instances.

Key features:
 ● 32 voice polyphony
 ● Two Super Saw oscillators, an upper and lower with panning
 ● 1 noise oscillator
 ● Three filter modes: low pass, band pass and high pass with -12 & -24 dB/Oct
 ● Three independent LFOs controlling the filter, amp and pitch
 ● Pitch envelope
 ● Glide (Portamento) / MIDI pitch-wheel support
 ● Built in delay and EQ
 ● 114 presets, which includes presets from CFA-Sound, MASCHINENBAUERMUSIC, Mikey O’Hare and Grzegorz


All sounds are straight from the JP6K. Some pad sounds use a slight amount of reverb.

Demo by CFA-Sound.

    This has become a contest to see how retarded this thread can get. The Mac guys are in the lead with no signs of letting up. The reason for no Mac has been stated. Many.Times.Over.

    Roland should contact you to make a Roland JP8000 VSTi – kond of like LinPlug and Rob Papen worked together…your G.U.I on the JP6K is fantastic and it sounds fantastic for it’s simplicity ( in a good way ) and it’s no-brainer price. I really wished Roland would pay you Big Bucks and hire you to Work on such a Project…I wonder anyway why Roland or Yamaha don’t sit down and produce something like Korg did with it’s highly beloved Legacy Collection. Seeing how much money Native Instruments or Arturia make with their Software Synthesizer even through cracked Software is everywhere should make them think? I wished you would design a Emulation of the Roland D50 or somebody would convert Yamaha’s FDSP Synthesis into a VST Instrument…so much potential out there…sad.

    You did a fantastic Job with the JP6K and I hope you will add more functions of the original JP8000 on a Update or Updated Version – I will sure be one of the first to grab my Debit Card out of my pocket…thank you for bringing us modern Homestudio Producers a “Supersaw” capable and affordable VSTi with professional GUI that hardly uses any CPU Power – highly recommended for all Trance Producers out there that want that typical Sound of 90ies Trance Classics in their repertoire.

    Wow, so many negative replies with a touch of insulting people. If everyone would think about it (without letting the anger take over) it is pretty obvious why some Mac folks keep asking: The guys over at SynthMaker did point out that there is a chance that they will make a Mac version if there is enough demand. Probably people try to show that there is a demand by posting here (thinking that Adam may prove feedback to the SynthMaker developers). Maybe these posts should be understood in a way that Adam has created something very extraordinary where some folks would be prepared to pay much more than the nice price tag which is set.

    I have a JP8080 where one of the oscillators is broken. I would like to down load onto a 64 bit windows 7 machine, will it be compatible?

    To clear up any unsubstantiated rumors, the official word from the guys at Synthmaker is to stop pestering about Mac support. They have never said that more whining would increase the chances of Mac support. In fact all the incessant whining seems to be pushing them in the other direction. They are NOT interested in their customers submitting more evidence of demand.

      It seems the contact form was disabled it works now. If the paying language is in swedish (I dont know why, for me its in english when I try it) then change the “se” in https://www.paypal.com/se/cgi-bin/ to “us” like https://www.paypal.com/us/cgi-bin/

          i’ve solved this problem now, but i can’t buy with paypal, i have problems since a few months. I’ve tried everything, it didn’t work. Can i buy it somehow else? via normal bank transfer e.g.? your massive soundset was one of the reasons i’ve bought massive a few days ago, if i can’t buy your soundset, that would be bad :/
