My new supersaw demonstrator
by rocknrollkat » Tue Dec 26, 2017 2:36 pm
Hi gang !
Yesterday the topic of Roland's supersaw came up, a feature of the Roland JP-8000, from 1997.
They used 6 sawtooth oscillators with the capability of tweaking the parameters; frequency (fine tuning), phase and levels, so I decided to 'build' one before breakfast this morning.
I haven't done any heavy research into the JP-8000 and this schematic makes no claim to actually 'emulate' a JP-8000, but the hookup demonstrates how detuning and phase shifting can fatten an already harmonically rich waveform.
The schematic comes preset at one pitch, fine tuning at '0' cents, and the Output levels at 50%.
That's your starting point, 6 dull as dishwater sawteeth (!), start fiddling with the dials and see what happens next !
In case you're wondering, a 'cent' is 1/100th of a semitone, seemingly insignificant until you kick out one of the generators a few cents, try it and see !
And remember, those level controls are there for a reason.
One of these gizmos can be a true Joe Meek leasebreaker !
Have fun and happy 'Boxing day' !

A good demo for those not aware of the possibilities of detuned Saw waves.
Did you check out my Quilcom 7SAW?

Thank you Spogg !
I'm aware of your Quicom 7SAW, but I haven't delved into it as yet.
I will get to it shortly and let you know, I'm sure it's top shelf !
