New JP-8 inspired voice boards by tiergrinder

Published on Oct 12, 2017 tiergrinder

"Finally I got around and installed the new voice boards to my Jupiter clone. I made a six PCB test batch almost a year ago and build the boards, but never quite got around to install those.

This patch is made using two saw waves, and a bit of detune between the oscillators. VCO LFO modulation modulates both VCO1 and VCO2 with mild LFO modulation.

"This synth is based on Jupiter-8's voice circuits and it shares 100% the same VCO circuits and MOD CON circuits with the original JP-8. Only small differences are that some of the rare transistors are replaced with modern versions.

Polyphony is cut from 8 voices to 4, just because the huge amount of components needed to finish one working voice.

My cover is not an attempt to match the original 100%.
All the tweaks are recorded live even though it might

"Fiddling with Roland Boutique JP08 and Jupiter Clone.
I tested my clone against a real JP8 once and know it sounds pretty much like the real deal, so I wanted to test how the new boutique sounds against a real analog.

I have to say, I simply love the new Boutique 'Jupiter'. It certainly has that jupiter sound and it also has that analog magic to it.
