Sequential Circuits Prophet 600 – Gligli Upgrade

Sequential Circuits Prophet 600

This Prophet 600 was brought in for a Gligli P600FW upgrade, which is a CPU/firmware upgrade using a Teensy ++ microcontroller board. It offers improved resolution for all parameters (128 values instead of like, 15 or 7!), a new LFO just for vibrato, arpeggiator MIDI sync and more, which you can read about here. The firmware is generously offered for free by the developer and in order to install it, we procure a Teensy 2++ board, do some modification to the Teensy, flash the firmware onto via USB, and install it in the Prophet 600 in place of the original Z80 CPU. We can do this mod for only about $100 including parts. Continue reading “Sequential Circuits Prophet 600 – Gligli Upgrade”

SIEL DK-600

SIEL DK-600

This is a really good one. SIEL was an Italian company that always quite clearly had their own way of doing things. It is a 6-voice DCO polysynth with the ability to make just beautiful, delicate, lush tones. The square wave can go so low that it just sounds like a lawn mower in the distance. That’s not a very useful feature, but for some reason it always delights me when I encounter it. Continue reading “SIEL DK-600”

50 underrated 80s polysynths

Here’s another article I wrote for Reverb.com, devised as a sort of year-end-list for 2017, profiling my favorite vintage polysynths I’ve worked on that can still be had for under $1000. This one’s for all of you who feel like you can’t afford to own a cool vintage synth. Some of these can be found for as little as $300!

Roland Juno 60

We had a week full of Junos (Junoes?), with three Juno 60s and four Juno 106es here all at once. These are the ones I did last week in between grinding away at various aspects of an insane Minimoog Model D restoration I’m working on and building a new power supply for a Rhodes Chroma.

Roland Juno 106 (#8) – common problems with the Juno chorus

yet another Juno 106

Since I always do pretty much the same work on every Juno and have posted about it 7 times, this time I’m going to go more into depth about two specific, very common problems a Juno 106 chorus/jack board can have. Continue reading “Roland Juno 106 (#8) – common problems with the Juno chorus”

Sold! Now FOR SALE in our Reverb shop!

I bought this Juno from a guy named Mike in South Jersey, with a shaved head and a gold chain. I met up with him at his garage studio behind a roller rink, where the Juno had been used for over 25 years by musicians providing live accompaniment for the roller skaters. Now the music is performed by two “old cowboys” (his words) on two Hammond console organs. I also met Mike’s overweight English bulldog, who he introduced to me as his girlfriend. I think her name was Bethany. Continue reading “Roland Juno 106 (#7) – this is New Jersey”
