new Buchla Music Easel – intermittent or “dead” touch keys?

Here’s a PSA about something we learned from a Buchla Music Easel (the new version) that we didn’t end up having to fix. We were told this Easel had an issue where sometimes, one or two of the keys on the touch keyboard just wouldn’t work. Continue reading “new Buchla Music Easel – intermittent or “dead” touch keys?”

Waldorf MicroWave 1 – SysEx Factory Presets

I hate to have to tell you this but your Microwave 1 will always be noisy. Its low sample rate will make it always click because of waveform phases not lining up as it runs through the wavetables, and the DAC will always produce a high hum and a loud chirp when you turn it off. You should still recap the power supply though.

I did a post about this synth only to put this here: Here’s the Waldorf factory preset sound bank which I edited to convert it from a .mid file to .syx  (System Exclusive) so you can dump it from MidiOx or SysEx librarian instead of grappling with timing the midi sequence correctly.

Note: this file is configured for a Waldorf MicroWave 1 with its device number set to 000. You should be able to send it to your MicroWave and have it load without doing anything to prepare your MicroWave to receive, but if it doesn’t work, check your device number (set via Device Param. menu).

A Moog modular restoration is a very unique and specific kind of restoration experience, which I’ll try to show mainly in photos because it’s less boring for you. It will be like a vacation slide show with a fun anecdote to accompany each picture. Continue reading “Moog Model 15 Modular”

Desoldering Tutorial: Tools, Techniques and Helpful Tips

the frikkin desoldering gauntlet

I would say that desoldering is much harder than soldering. It took me a couple weeks to get good at soldering and several years to get good at desoldering, partly because I didn’t used to do it as often when I first got into electronics, just building circuits from kit PCBs and schematics. Working on old synths though, I have to desolder all kinds of things constantly from different kinds of boards and have refined my techniques pretty well, so I thought I’d share some of what I’ve learned here.

Roland Jupiter 6 – calibration tips

The Jupiter 6 is one of Roland’s two most beloved 80’s polysynths, the other being the Jupiter 8. While I was looking for service documents for the Jupiter 6 though, I came across some absurdly aggressive forum posts from people who don’t like this synth and are pointlessly mad that a lot of other people like it a lot.

a DCO is not a digital oscillator

VCO vs. DCO vs. Digital Oscillator

I keep hearing and seeing people referring to DCOs as digital oscillators, which is not correct, and a sad insult to DCOs in my opinion as a lover of DCO synths. So I decided to fight misinformation by making a post here explaining the actual difference between VCOs, DCOs and digital oscillators. Continue reading “a DCO is not a digital oscillator”
