Roland Jupiter 8

The Roland Jupiter 8 has a massive sixteen analog oscillators for some serious layers of texture, with eight voices of polyphony, you can quickly see why this was Roland’s flagship instrument, some even argue it still is the best they have made with only around two thousand ever made it commands a high price on the second-hand market.

Using subtractive synthesis with many parameters for sculpting right there on the control surface of the colourful unit, you can pretty much make any sound that you can dream up. Comparable to the Prophet 5 it has left a historical mark in the music industry in many a studio around the globe.

You can split the keyboard into to patches, so bass and pads for example, having a separate patch available on each side. The first models of course did not have midi, but this was added to the later line of models. Speaking of patches, it could store up to 64 patches and with the Encore JP8MK MIDI kit this was doubled to 128, allowing the user to store and recover your sounds over a MIDI connection.

It has CV inputs that can be synced to the onboard arpeggiator, it has balanced plus unbalanced XLR outputs. All sixteen oscillators can be stacked onto one note which is amazing for the time that the Jupiter 8 came out as no other synthesiser had this feature.

Each voice on the unit has 2 VCO’s (voltage-controlled oscillators) with cross mod, sync, pulse width, a non-resonant and a resonant low pass filer, with 12/db. and 24/db./octave options.

 

 

FINAL WORD:

Incredibly deep analog sound rich textures from effects to basslines, used on many a hit recording spanning across many different genres. If you can afford to get one that comes up for sale buy it!
