"Take a good Eurorack Oscillator and with a couple of key modifications make it a great performance Oscillator! First remove the single turn potentiometer that controls frequency and replace it with a high precision ten turn potentiometer. This gives you much finer control than even the existing fine tune knob. Speaking of which, since the primary potentiometer is now much finer than the ‘fine’ tune knob, replace it with a +/- Octave switch. This makes it easier to move up or down an octave depending how you have set the frequency knob.
You can set the amount you want to move up or down by adjusting these added trimpots for the +/- octave switch.
This original idea was from Darwin Grosse (20 Objects) who likes to perform as often as he can and uses his Eurorack modular primarily when he does perform. He told me ‘I think there is enough room to fit a ten turn pot in this Pittsburgh Oscillator.’ After carefully taking one and cutting out the front PCB I realized there was. I quickly made a couple for him and one for myself and now I must say I am spoiled and wished more Eurorack modules had these ten turn pots!"
"A quick patch project based on some Euclidean Rhythm ideas recently discussed on the Muffwiggler's Forum. Since I don't own a single module like the COTK C969 Eclidean Bi-Clock Sequencer, I decided to rig up my modular to impersonate the general idea.
Patch details include...
The kick drum, snare and bass line are using variations on 16 beat patterns. The other two elements are 12 beat with 2 fills and 11 beats with 4 fills respectively.
The patterns are as follows...
kick = 16 beat 7 fill
snare = 16 beat 6 fill
bass = 16 beat 4 fill
RM voice = 12 beat 2 fill
second voice = 11 beat 4 fill
The 20Objects.com Ardcore 001 & Ox are handling the 16 beat patterns with the AC14 Gate Sequence sketch.
The Synthesizers.com Q960 Sequential Controller is generating the main clock and the 12 beat pattern with 2 rows of six beats and the first beat output.
The Q119 Sequential Controller is handling the 11 beat pattern by using the voltage output as a gate.
The STG Soundlabs VMS is sending pitch voltages to the 12 beat pattern's VCO's (ring modulated voice).
The Sputnik WCRS is generating quantized random pitch voltages to the 11 beat voice.
All pitch voltages are quantized through the dual Q171 quantizers from synthesizers.com.
The bass line pitch voltage is using a slow square wave LFO through a Q125 signal processor and a channel of a Q171 quantizer for a shifting 2 pitch pattern.
The kick drum is a Polivoks Filter resonance. The snare is white noise through an Oakley Diode Ladder Steep and mixed with the enveloped white noise then a touch of room reverb from a Strymon Blue Sky reverb.
The patterns were first realized using Wouter Hisschemöller's "Euclidean Rhythms Generator" java script. See: www hisschemoller dot com for further info."
"This is an example video for the ArdCore Output Expander. It generates a clock signal, and provides a number of alternating triggers for the output. In this case, different triggers are used for two sequences, a sample and hold module and an amplitude envelope. NOTE: this ArdCore is equipped with the optional switch on the A3 input for turning the clock on and off."
Update: ArdCore stands for Arduino Core. You can find info on it at 20Objects here. SnazzyFX produces a eurorack version.
"Drums!!! Alfonso Alba (fac) submitted an amazing drum player sketch with CV control of pitch and sample select. This adds quite a bit of functionality to the Ardcore and shows what can be done if you know how to program! But Alfonso has made it easy to bring drum sounds into your modular without knowing anything but how to load up a new program."
Just thought I'd consolidate everything into one post. First is the flickr set of pics I took (288 in total) in the order taken, followed by the videos in the order taken. Links to the individual posts at the bottom.
Saw these at NAMM. They are open source and fully programmable. These modules can basically turn into whatever you want. Very impressive. I should have a NAMM floor vid coming up in a few days.
Playlist: 1) ArdCore Sketch 18: Variation Generator Uploaded by 20Objects on Mar 24, 2011 This is a simple example video showing the ArdCore sketch #18 running on a hacked-together version of the ArdCore module. It produces output variations that can be used for clocking other modules, or for creating rhythmic drum tracks.
2) ArdCore Sketch 04: Drunken Note Uploaded by 20Objects on Apr 4, 2011 This is a demo video of the various functions of sketch 04 for the ArdCore modular synthesizer. For more information, check out www.20objects.com
3) ArdCore Sketch 16: Clock Multiplier Uploaded by 20Objects on Apr 6, 2011 This is an example video for sketch 16 - the clock multiplier. It's useful for creating polyrhythms or for using ratcheting effects.
4) ArdCore Sketch 23: Voltage Recorder Uploaded by 20Objects on Apr 8, 2011 This sketch provides some interesting options for recording voltage streams within a modular synthesizer.
5) ArdCore Sketch 02: Quantizer Uploaded by 20Objects on Apr 10, 2011 An example of how to use the ArdCore quantizer within a your modular
6) ArdCore Sketch 06: Trigger-to-Gate Uploaded by 20Objects on Apr 12, 2011 This sketch shows the use of the ArdCore to transform trigger events into gate voltages, under both manual and modular control.
"In Eurorack and 5u there is the forthcoming ARDCORE module.
It has ins and outs, CLock in, trigger and gate outs, a usb port, etc and is based around Arduino and Darwin Grosse's custom library of programs focused on Modular Synthesis. (25 programs and counting)
voltage recorders, quantizers, drunken walk generators, lfos, shift register, trigger multipliers, etc
My company (snazzy fx) is releasing the Eurorack version and Darwins company 20Objects is releasing the 5u."
