Ok, but surely you mean 30mm thick, not 300? We'll probably go with the thicker aluminium (if we can find it cheap enough, B&Q only had 0.5mm aluminium). We've decided to buy a flat pack box from Ikea and cut the "solid birch" up a little to give us the correct dimensions. One mo

I haven't built a 16 step Seq Switch, however it's farily easy link up two eight steppers for 16 steps. You just need a few helper modules. I run the ouptut of the first into the mix input of the second, and use a third 2-step sequencer (running at /8) and inverter to turn each s

I see some mention in the archives of someone thinking about building 2 of these in parallel and Ken mentions to use the reset function to keep them in sync. Did anyone ever get around to building it this way? I would like to build 2 units to run parallel in only sequencer mode.

MOTM style panels are made from a flat, rectangular piece of aluminum, usually 300 mm thick. Modcan B panels are made out of a much thinner sheet of aluminum, with added rigidity from having the edges bent over to form a channel. Here is a picture: http://www.modcan.com/bphoto/re

Hi, Yes, it must be the Modcan B panels. When you say "physically different" do you just mean how they look? My dad and I are going to build a cabinet adapted from the Dotcom instructions with two shelves with 9U to each shelf. I may have to show my dad a few pictures beforehand

There are still plans up on Larry's old site for DIYing them. His magic bus was brilliant! I'll have some assembled ones on my site in a couple weeks, but the brackets will take a month or more. Scott Deyo The Bridechamber contact@... www.bridechamber.com On Aug 25, 2006, at 5:14
2006-08-25 by Richard Brewster
I guess you mean Modcan B series, which is the same form factor as MOTM, although the panels are physically quite different. Be sure to check out the ModularSynthPanels Yahoo group: http://launch.groups.yahoo.com/group/ModularSynthPanels/ I had not see the dot com DIY cabinet pag

There is no hard and fast rule. My earlier modules were all mounted behind the .com/moog sized panels. Now days, I use Serge format. The boards themselves fite behind either. A number of people have designed panels for MOTM, and these can be adapted for use on the .com Ken >Hi, >

Voyager? Isn't that a fictional spaceship? :) I have not found a great way to document patches. I do it in odd ways. I sometimes draw them on 11 x 17-inch graph paper. But that isn't easily reproducible. Describing a patch in writing is possible, but not so easy to read. There ar

The "odd-tip" LOL. Thanks for the compliment, Thomas. You could shift a pulse through the ASR. It can handle inputs in the +/-10V range. But the CGS Gated Comparator module is better suited to pulse shifting, and it has eight stages. Richard Brewster http://www.pugix.com thomas w

Hi, Both my MIDI-CV and PolyDAC(X) MIDI Converters require a stabilised +/-15V DC supply. Ken's CGS14 will work fine with these boards. Similarly so will my PSU-1. Please note that both the CGS14 and PSU-1 require a transformer supply for operation (typically 36VAC centre-tapped)
2006-08-19 by Future Image
Ok, just looking at your MIDI-CV converter, will I need the PSU-2 for that to supply 15V or does the PCB already have a regulator on there? I'd like to have the MIDI-CV as an "external" module so I can take it anywhere to use with any analog synth. --- In cgs_synth@yahoogroups.co

Stick a small resistor in series with each of the 2 power rails (+ve and -ve) and measur the voltage drop across them. Apply Ohms Law and Bobs'your uncle. For example, lets assume the module draws 10mA in each rail. If you put a 10R resistor in each rail then you would expect to
