DIY Analog Modular Synth

A short clip of my DIY Analog Modular Synthesizer . No Midi, Keyboard, knob twisting, overdubs or computer - It's playing on its own in real time.
Module designs from MFOS, CGS, Electro-Music.com and wherever I could scrounge schematics.
Sorry about the real poor digital camera vid and audio.

monophonic? It depends what you mean by that...

There are 7 VCO's and four sequencers at last count. If I use a keyboard only - yes, it's monophonic - one key pressed at a time. But I don't use a keyboard much.

@bchris1776 how did you use the casio keyboard? i just took the keyboard assembly out of the shell, i have yet to pop the board with all the diodes off the keyboard (for lack of the proper sized philips head and didn't want to make too much noise with my drill at 2:19 am ;) ) is the keyboard assembly digital or analog? all i see atm is ribbon cable so i cant tell.

[bchris1776]

@TelcoBob Pull all the diodes, jumper the common grounds, and trace each 'bubble switch' to a point on the PCboard. Solder a wire to each bubble switch point and run it to a resistor ladder. I used the MFOS Keyboard controller with it.

Next time I'll avoid bubble switches and use a better quality key assembly.

DIY?! Did u make it in your self?

great work! i tell u mate.

[bchris1776]

Thanks yasushi73 - Yes, I've built it over the last 3 years...and still working on it. Quite a few modules have been added since this clip.

How do you get a keyboard for the module? I plan on getting my first Modular synth, and all I find are Modules, not keyboards WITH modules.

[bchris1776]

Although no keyboard was used for this clip, I do have a 1V/Octave keyboard I built... I hacked an old Casio (CT-310?) for the key assembly and built the Ray Wilson (MFOS) circuitry.

You could also purchase a midi-CV adapter and use any midi controller - that's probably the easiest way.

nice to see something logical coming out of a modular setup

rare on youtube indeed

sounds alive dope!!!

*raises coffee cup* Few people use modulars to actually make good music. much less even making the system itself.. You sir, are one of the only truly deserving people to own such a great machine... All others just have way too much money to throw away.. I can't wait to get my Lunetta modular finished. Truly inspiring video

It's really good ;)
