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.


Download demo version:
Demo restrictions: Preset saving is disabled, silence every 60 seconds. (Because of the demo limitations, automation is not available in some hosts, but is fully functional in the retail version)
Requirements: Win 32/64 compatible system with SSE2 (or higher).

This is a 32 & 64-bit VST for Windows only! All future updates are free!
Please evaluate the demo thoroughly before purchasing!

Why no Mac version?
Unfortunately, FlowStone does not yet support export to AU, Mac VST yet. As soon as FlowStone supports this, the synth will be available in this format.

    Does it load sysex file, can it generate sysex file ?

    Will this work on a 64-bit system? Hoping for a Mac-version for several years but im on pc now so eager to try this one! Cant see the plugin in Ableton though.

    Best regards

    Alright mate synthmaker is now 64bit, so a 64bit version would be awesome. Seeing as Cubase 9 is dropping 32bit bridge support, I can’t even bridge it. Though bridging it in 8.5 isn’t very reliable either.

      Where did you read that synthmaker is 64 bit? Its still only 32 bit as far as I know.

        There is no plan to port Synthmaker/Flowstone to 64-bit. In fact it will probably never be 64-bit.

        Synthedit, yes, it is currently on the fire with a lot of VST makers used as beta tester (among them me and many friends) but there are still many bugs, the progression of the project is extremely slow and it will probably not be ready before at least one or two years. At least…
        But Synthmaker/Flowstone no, the project has even never been started and probably will never be, the company refusing to port Flowstone to 64-bit.

    JP6k is must have plugin for trance music. In my opinion great powerful sound the same as we know from jp8000. Adam, when can we expect a version for mac?

    I have to say, this synth totally captures the sound I was looking for, and its incredibly easy to use. Worth every penny imo!

    Hi Adam, maybe you can get in touch with developers with some C/C++ and DSP knowledge to build a native 64Bit version for PC and Mac?
    Synthmaker with 32Bit only is a no go.. Sorry!

      JBridge is an excellent tool. Sorry.

    Such a great and exact emulation of the original JP8000 super-saw, except it needs one more crucial element… the chorus effect. See if you can update the JP6K by adding in the exact chorus effect as the original JP8000’s built-in chorus effect to fatten up the super-saw sound and give it its legendary flanging twang effect. But overall, this is such a great and legendary JP8000 emulation!

      Ah the chorus effect, yeah that would be the completetion of this emulation.
