Jupiter 8 modified with Pyxis aftertouch demo

Published on Aug 20, 2013 kpsiegel

"I had my Jupiter modified to accept a New England Analog Pyxis aftertouch system along with an aftertouch pressure pad. It allows me to do the following:

Bend VCO1 and/or VCO2 with aftertouch in the same or different directions. Very nice for aftertouch detuning.

Open the filter cutoff and/or add an additional triangle or square wave LFO as a filter modulation if desired with aftertouch

Modify the VCA volume and/or add a triangle or square wave LFO tremolo wtih aftertouch

The rate of the Pyxis LFO can also be affected by the aftertouch sensor.

Basically a lot of cool stuff. This mod also allows you to have the aftertouch active or not at either split point for split keyboard mode patches.

For this demo the Jupiter 8 had NO filter modification done by anything other than the aftertouch system. No envelopes at all come into play. An H3000 D/SE was used as an effects box for reverb and delay."

Jupiter 8 improvisation

Published on Nov 3, 2013

"I recorded an improvisation on my Jupiter 8 with a pyxis aftertouch system. I used an Eventide ModFactor for Chorus, a vintage delay on the Eventide TimeFactor, and a Hall reverb on the Eventide Space. I have the Jupiter set up as two layered patches which I fade between as things go on. This was all recorded directly into my DAW.

Aftertouch controls the filter cutoff, VCA level, and some vibrato. At one point I set it to allow me to bend oscillators individually. I have this switchable so they can bend in different directions if I want to do detuning effects with the aftertouch.

It starts with a classical feel with apologies to Brahms in the beginning and then things get moving. Rhythmic filter cutoff bouncing is done with the aftertouch as the mod lever sets the cutoff up and down around which the aftertouch filter control works. A nice effect to play with."
