BOSS DR-220 Eurorack Modules

How can you not love late 80’s drum machines?  No CV control, you say!  Well, here we had to add CV control over some of the choice bends and latching switches to allow complete manual control.  Trig inputs for all of the percussion too!  A TTLFO which can be used as master clock, or used to turn on and off the 8 CV controlled bends, that have been meticulously gone through to find some of the best ones!  One of my best conversions to date. 😀

FUN with FM Radio and euro modular!

I have an ADDAC 102 voltage control radio module and it has not gotten much use, so I had an idea to add some spark. They sell these cheap FM wireless transmitters that are pretty cool and pretty cheap. They contain a Li-Ion battery and are USB rechargeable. I switched out the mic with a plug, added a 250K trimpot and now I can use whatever source I want to bring in an out of reception. I might make a couple of them just for different sources using a sequencer. Anyway it has brought back life to using my voltage controlled radio!

Merry Video Synth Christmas to me!

Hosa sent me some free cables to try out!  Now that I have had some time to check them out I can honestly say that Hosa sent me a great Christmas gift indeed!  I have put these cables through their paces and I am impressed!  I have received crap from some of my friends over the years for using Hosa cables.  But I find them absolutely indispensable!

Here are a few pics of my finally finished eurorack video synth and I have used my new Hosa cables to make some sense of it.  I am using various LZX modules and a couple of my own design/hack modules.  Using LZX modules means you will be dealing with Red, Green and Blue signal sources.  These new cables from Hosa are standard primary colors and that is great for these.  Looking at the pic below can you easily find my RGB signal routing? Having the velcro ties makes this easy too!  I can pull the three color combo signals and keep the cables together. Even after receiving several free cables from them, I went and bought some more just for my video synth!  Check em out HERE!


Custom Korg MINI KP eurorack module

One of my favorite types of emails are from people who love their non-eurorack gear so much that they want to find out, ‘if’ it is possible to convert over to eurorack, and what would be involved in doing so.  At first I was not sure if conversion of the Korg MINI KP would even be possible.  I usually have to go back and forth with the inquirer and see if they can ‘carefully’ open the ‘back panel’ and look inside and see what we would be facing.  I ask for a couple of pics and some measurements.  Basically the main hurdle in euro conversion is the physical size of the PCB’s that are inside the synth/pedal/effect box you are trying to convert over.  Yes, current use, digital functionality, midi conversion, voltage needs, among other concerns need to be addressed, but the size of the PCB’s is the most critical ‘show stopper’ that has to be addressed first!

I asked Ali a few questions about his MINI KP and the journey with it so far.

What is your history with the Korg MINI KP?
I’ve owned one since about 2009 when I bought it to run my Nord Electro through live Continue reading

Will Moog release a complete eurorack system?

This month marks the two year anniversary of the Mother 32 Eurorack module release from Moog.  That was a glorious moment for Eurorack enthusiasts worldwide. Moog gave us hope and insight to what their possible role would be going forward into the Eurorack modular synthesizer world.  Since then we have seen other possibilities from them, with a handful of various Eurorack prototypes, mostly from their limited access Moogfest VIP engineer attendee’s course.  But as time ticks by some us have started to become concerned that we will not see anymore publicly released Eurorack modules with the Moog brand on them.  SO, we hope to inspire Moog with our re-panels of some of their existing line of synths and effects that we have carefully converted over and now display as a combined cohesive custom Moog Eurorack system.  Since Moog has re-released previous 5U combined modular synthesizer systems, maybe they would entertain releasing a complete Eurorack modular synthesizer system similar to what other Eurorack module makers have done in years past?  Maybe they have dozens of Eurorack module designs, ready in the wings, just waiting for release?  We are hopeful and Christmas is just around the corner, maybe we will have a happy modular holiday season after all!

Here we show the Eurorack converted Moog MoogerFoogers, MF-101, 102, 103, 105, 107, and 108.  A Moog Minitaur Bass Synth, and a Moog Werkstatt synth.  A Circuit Abbey Unify mixer with expander.  A 2HP mult and two Div 6 16 step sequencers to round out the system’s functionality.  All of this housed in a custom 9U Goike case.

Sorry for the open mic noise. I forgot I had it on. Watch out for the Lamborghini, it’s gonna run you over! This is mostly all bottom end, so forget about output from crappy computer speakers.

Starts with the Minitaur, then the Midi Murf which is output to the Phaser, then Freqbox is fed into the Cluster Flux which is the Lamborghini!



Where would you use a custom Moog Eurorack Synthesizer like this one?  How about sitting on your Rhodes piano?

Minitaur Eurorack DIY Conversion Kits

Do you want a bad ass analog bass synth in your eurorack? This is the way to go! These kits are over two years in the making. If you don’t want to or can’t DIY then send me your Minitaur and I can convert it for you. For an additional fee.

NO LONGER AVAILABLE!!

Moog MF-108 Cluster Flux Eurorack Module

This is getting exciting now!  This  is one of my favorites from Moog.  If Moog was to only convert one of their MoogerFoogers over to the eurorack format, it should be this one.  What’s not to like?  Chorus, Flange and Vibrato driven with original bucket brigade device chips.  Multiple waveform LFO, which you can sync multiple ways, including MIDI. And feedback that sucker till you go deaf with happiness!

Moog MF-105 Midi Murf Eurorack Module

The Midi Murf has taken more time to convert over than I had originally anticipated.  There were several challenges in getting all of the control hardware to fit in a reasonable sized HP space.  Based on the effort it took I can say with confidence that I will not be converting a lot of these over!


Moog Werkstatt 01 eurorack module

Ok, yes, I have converted these before, but not in the same aesthetic of Moog’s current eurorack line. I was able shave off a few HP’s too making it smaller than the original conversion. These custom conversions are leading to somewhere right? More coming soon 😀
