Roland Juno-106 VS Juno-106 Gravitational Slingshot Synthesizer Comparison

On the bottom tier is the wonderful Roland Juno-106 in all its original glory. No mods, no apologies. Going against the upper tier Juno, not only are the Gravitational Slingshot chips installed but also having the Analogue Renaissance waveform chips as well. I'm auditioning the same patches as loaded on both. Are you ready for a showdown? Which one comes out on top?

These patches are available for download at GUMROAD Audio recorded direct to iPhone via Roland GO:Mixer Pro-X via Soundcraft EPM6 Mixer. Aside from some normalization, no additional effects or processing were used.

Roland Juno-106 Synthesizer - That Juno Sound (no talking)

Today I'm auditioning some of my original patches the Roland Juno-106. I just love the 106 for those plucky arps, sweepy portamento pads, classic chorus circuit, weird resonance chops, and not forgetting those basses. The range of sounds inside the simple architecture is littered with sweet spots. I've lovingly crafted a bank of patches to harness these attributes, now these patches are available at Gumroad. Audio recorded direct to iPhone via Roland GO:Mixer Pro-X via Soundcraft EPM6 Mixer. No additional effects or processing were used.

JU60-VCF Eurorack Filter Adaptation Roland Juno-6/60 Jupiter-8 Now Available

JU60-VCF is an analog 4-pole low pass filter adaptation of Roland Juno-6/60 using a vintage IR3109 chip with a BA662 OTA chip in the resonance feedback loop. This topology was also used on the Jupiter-8, with a switch for tapping the 2-pole mode. Resonance will self-oscillate and produces a nice sine wave alone. JU60-VCF won’t turn your system into a polyphonic synth, but it has a classic sound at a sweet price. Time to get out your favorite stereo chorus modules and pedals!
