Ieaskul F. Mobenthey Eurorack Modules From Ciat-Lonbarde's Peter Blasser

via Control

"Peter Blasser's - Ieaskul F. Mobenthey modules are now In-Stock. Couldn't be happier to have Peter's stuff in-stock, he's been pushing the limits of instrument design and the philosophy behind it for years with Ciat-Lonbarde and very much encompasses the ideals of what we find inspiring about synthesis, electronics and the makers who make them. Limited Qty available."

Details on each, captured for the MATRIXSYNTH archives, follow. You'll find a video of them previously posted here.

"Ieaskul F. Mobenthey - Denum

The Denum module is essentially a bounds/bounce oscillator. It has the “triangle core” circuitry used in many
oscillators, but it adds a correlated bounds modulation, according to the concept (see below). Here, bounds and
bounce are each given equal treatment, with separate linear and exponential controls and inputs. In addition,
this module has a fully featured bi-polar VCA with complimentary inputs, to get you quickly going sending
“bb-objets” out the left and right channels.

Denum is an 8HP Eurorack module that runs on +12 and -12 volts. Attach power connector positive to “+” and
negative to “-”. Failure to follow proper power polarity will result in instant destruction of unit.

Looking at the front panel of Denum, note that inputs are marked by copper fill. There are three main sections:
bounce, bounds, and the VCA. Bounce is above bounds to emphasize the numerator/denominator relationship
of the two. Each of the two has exactly the same inputs and knobs. The “basis” knob sets the base rate or
position for bounds. There is a linear control input, marked by a a caret. Linear modulation is an alternative
input for pre-enveloped audio, since it has no attenuverter. However, the exponential control input is tied to an
attenuverter, marked by a characteristic bow-tie. An attenuverter works like this: at noon the modulations are
nulled out, they have no effect; clockwise from there they increase in intensity, with positive input meaning
“more”; to the counter-clockwise direction, modulations increase as well, but with negative input meaning
“more”. This knob is essential to controlling how much, and in which direction, your modulations apply.
Between the bounds and bounce areas, there is a range switch. When in middle position, Denum runs at a
standard audio rate. Pointing downward is a low audio rate, and pointing upwards is a definite CV, lowest rate.

The triangle output speaks the position of the waveform in voltage, and square expresses the frequency in terms of
negative and positive 10 volts. The triangle output is bussed into the left and right audio inputs of the VCA,
at bottom. Either can be swapped out for external audio energies, via the “left, right signal inserts”. The “left,
right VCA inputs” are for controlling the amplitude of the signals, with either a linear or exponential mapping. If the
left input is greater than right, sound goes out the “left out”. If right is greater than left, sound goes out the
“right out”. The voltage amount of difference maps to loudness in these channels. The “linear, expo switch”
chooses linear when cocked up, as marked by a caret, and exponential when cocked down, as marked by a
rounded form. There is an optional mute when the switch is in the middle.

Guitar Pickup Simulator

This one in via Tom Whitwell of Music Thing. BTW, you can now follow him on Twitter.

"My latest DIY thing - good for plugging synths into stompboxes and guitar amps.

Simple passive circuit in a 1590a box.

Circuit comes from this article by Jack Orman: www.muzique.com/lab/pickups.htm

It's half a 10k audio transformer (a Triad TY-141P), a standard guitar volume/tone circuit with orange drop .1uf cap, then a 10ohm carbon comp cap and a 470pf cap to simulate a long cable run.

Basically, it rolls off some top end, but also makes the impedance of whatever source you plug it into a bit more like a guitar pickup.

So, synths sound better through stompboxes, particularly finickity fuzz boxes. It's also a bit like a DI box...

The switch selects no/half/full transformer coils. A bit like single coil v humbucker pickups."

Mini Mixer (With Atari Punk Console, Cracklebox & PO-12) : Basic Features : Vaemi (Synthesizer)

via Vaemi Reverb

via Vaemi Reverb

Vaemi's new product, the Mini Mixer, is a mono analog mixer with 4 channels and 3.5mm mini jack inputs and outputs, designed for use in stage performances or recordings with all your line and analog equipment. Each channel features a saturation function, and it has a specially designed jack input for the 4th channel.

When the 4th channel and jack input are empty, the mixer’s master output is rerouted to the inputs, creating a "feedback" circuit. This feature allows the sound gain to increase by approximately 6 times, significantly raising the saturation level of the mixer. If an instrument is connected to the 4th channel, the feedback signal is disabled when the jack is plugged in, and the instrument's sound becomes part of the summing. When the channels are muted, the feedback enters self-oscillation.

Playlist:

1. White Noise! Drums & Percussion from a cheap Ebay module.

"White Noise is a basic ingredient in the creation of electronic musical instruments, especially drums and percussion.

In my Ebay hikes, I found this small and dirt cheap (1.30$) kit that makes healthy white noise and I headed on to make some sounds with it.

Connect the Vactrol in place of resistors R4 or R5, for different effects.
For Modular output level, replace resistor R3 with a value of 8-10K ohms.

Using a self built musical instrument is so much fun!

Strip board Layout for my module

3. A DIY Clock Divider Groove

You can program drums without a sequencer!
A clock divider is a module which creates various divisions of an input clock, the rhythmic base of the system.
I built a module using two cute chips:
The CD4040 divides the clock in multiple of 2: 2, 4 ,8 ,16 ,32 ,64 , 128 etc.
The CD4022 is a simple counter. By deciding how far it counts, we can create more interesting divisions, like 3, 5, 6, 7 etc.
Each division triggers a different drum module, which creates a lovely automatic rhythm.

אפשר לתכנת תופים ללא סיקוונסר!
מחלק שעון (עברית שפה קשה), או Clock Divider הוא סוג של מודוּל שיוצר חלוקות שונות של קלוק, שהוא הבסיס הריתמי של המערכת.
בניתי קלוק דיוויידר (עדיין ללא פאנל) שמורכב משני שבבים חמודים. ה-CD4040 מחלק ל-2,4,8,16,64,256, וכן הלאה ואילו ה-CD4022 פשוט סופר קדימה. ניתן להחליט עד כמה הוא סופר ואז לגרום לו לחזור לתחילת הספירה. כך אנחנו מחלקים את הקלוק למספרים מעניינים יותר...
כל אחת מהחלוקות נשלחת למודול אחר של תוף אלקטרוני וכך נוצר לו מקצב אוטומטי אך מגניב!

5. Adding a Bluetooth input to the Studio Console

This happens all the time!
I meet a musician in my studio and he wants to play me a demo from his phone.
I start looking for a cable to connect to the patchbay, only to realize that it's a new iPhone with no analog audio connector.
A friend who builds studio monitor panels told me he started incorporating a Bluetooth input so I decided to add one to my Control 24 console.
I strolled down to Ebay and found a BT 4.0 module, built a steady power supply and connected it to the patchbay instead of the defunct CD player.
It's compressed audio, but hey, it gets the idea across!
זה קורה כל הזמן.
מוזיקאי שאני פוגש באולפן שלי רוצה להשמיע לי סקיצה מהטלפון שלו ואני מתחיל לחפש כבל כדי לחבר את הנייד שלו למערכת שלי. אם מדובר באייפון 7 ומעלה, אז בכלל אין על מה לדבר כי אין לו בכלל חיבור לכבל אודיו!
איציק אליהו הגאון סיפר שבקופסאות המוניטור החדשות שלו הוא משלב חיבור בלוטוס, איזה רעיון מבריק!
החלטתי שאני מוסיף בלוטוס לקונסולה שלי.
כהרגלי, פסעתי לאיביי ומצאתי שם מודול בלוטוס 4.0 ב-7.5 ש״ח. בניתי מעגל קטן סביבו עם אספקה יציבה של 5V וחיברתי אותו לקונסולה במקום הקומפקט דיסק שכבר מזמן שבק חיים.
זו אמנם דאטה מקומפרסת אבל זה עובד!

the kawai k1m is a hybrid synthesizer that relies on pcm sampling and additive synthesis based on harmonics. it's sound can be morphed via the vector joystick. this blend of synthesis along with circuit bending makes for a truly special and unique synthesizer that would be impossible to achieve otherwise.

under midi you have multi-timbral control, aftertouch, modulation, pitchbend, split points and other features that make this a musical instrument. this puts this in a league beyond circuit bent toys. truly a circuit bent musical instrument.

all bends have been carefully selected and are completely stable.

in the video demo below you'll notice i've setup all the bends under midi. the k1m's bends are open ended and can be controlled under midi with spunkytoofers midi modules. all instruments by spunkytoofers have been redesigned to be a modular system which can be controlled or intermodulated with one another. the k1m gives you complete manual, analog controls over the bends but all instruments are designed to be controlled under midi. on the k1m the bends can be modulated by sequencing or triggering over midi and the sample rate control can be modulated either by footcontroller or outputs from a spunkytoofers midi module freely assignable from midi cc's, notes, etc.

along with the instruments ability to be fully controlled under a midi modular system all instruments are also supported. i will back my work for free warranty work and will assist customers with any instrument they purchase from me as they are instruments i work with in my music performance and sound programming.

the video below demonstrates very simple setup under midi. the pads on a akai keyboard controller are used to toggle bends on and off under midi. this would be the same as manual control over bends except that it's easier for me to trigger the bends all from one controller. the banana cords are routed from spunkytoofers midi matrix module to the k1m's banana jacks. the midi module is also sending potentiometer control over midi to the k1m at the 1/4" trs jack with a sequence from the dave smith evolver and via midi mod wheel on the keyboard for more variation. please note i choose to modulate the module under 10k control. this can accept any value foot controller or potentiometer value beyond 10k and is capable of a much larger range of control. no effects are applied and the k1m is recorded direct from the module's output."

MITS Audio Sweep Generator

via this auction
"This is a working vintage tone generator which can be used for testing oscilloscopes or for producing cool vintage synth sounding effects. It is marked "MITS Audio Sweep Generator". It big dials on the front, some switches and screw terminals for connecting to whatever you want.

From left to right the dials are: "SWEEP RATE (10MS to 1 SEC)", "FREQUENCY (1 to 10)", "FREQ. RANGE (switch between 10, 100, 1K, 10K, 100K)", "WAVEFORM (switch between sine, triangle, square)", "AMPLITUDE (0 - 5)" and "ATTENUATOR (switch between 0DB, 20DB, 40DB)".

Along the bottom row, left to right: on/off switch; power indicator lamp; SWP terminal; SYNC SWP and WAVE terminals; OUTPUT DIR, GND and ATTEN terminals; SWEEP mode switch (SWP or CW); SWEEP reset buttonl SWEEP RATE switch (x1 FAST, x100 SLOW).

Condition wise the front panel looks awesome. It has a brushed chrome panel. The top cover is powder coated black and has a few chips and flaws. There's a silver label on the back with serial number "E11063", Mits logo and the text "Micro Instrumentation and Telemetry Systems Inc."

Dimensions of unit: 13" x 7" x 4"

circuit bent e-mu xl7 command station w/ mm1 module

"this auction is for the circuit bent emu command station and the mm1 midi module the unit was purchased as a brand new instrument. the previous owner said the command station was used for only a few hours. i have confirmed this and the unit internally is pristine. all knobs, buttons, outputs, velo pads, ribbon, etc are in pristine shape and just like new. the outer shell was painted and salvaged from a emu mp-7. internally it is a xl7 and is absolutely in mint shape. i've had this unit for a few weeks now and can confirm everything is working perfectly both in mm1 and emu command station. this is a one-off offer and most likely will be the only one in existence

the following audio is several drum tracks played in realtime with a simple appegiator programmed for each sound. the emu sports 32 independant arpeggiators. the drums are then circuit bent and leads into a formant synth texture controlled with a wind controller.

Teenage Engineering "Pocket Mixer"... Say What?!

Published on Feb 7, 2016 djthomaswhite

"The demo explains everything really, but to make it quick I made a mixer and sync distribution device to use all 6 currently available Pocket Operators at the same time with an audio mixer and 1/4" out jack. Fun! If you like what you see let me know in the comments. With enough demand I may make these with powder coated case, silk screen and color coded knobs.

For the curious - Technically this is a passive summing mixer with 100K Pots and 10K summing resistors. The sync is simply split from the input jack to the output jacks with one single copper wire. Easy peasy. I will use Log (audio taper) pots in the final design. Pan and stereo outs would be hard without adding active circuitry.

Don't be afraid to get your hands dirty. You can do it! Thanks for stopping by to check out another one of my projects captured on video."

miniMusic MixPad

"MixPad is a full featured MIDI file player/recorder/editor. It will let you take any raw MIDI file with you on your Palm compatible handheld or phone. You can play the song with our Krikit audio engine, on connected MIDI hardware, or on a sound card if your handheld has one. MixPad differs from any other MIDI file applications for the PalmOS; it includes powerful graphic support for simple viewing and mixing.

Usable for real performance situations, or music practice, MixPad gives you a powerful real-time mixer interface to control channel volumes, panning, and solos and mutes for every track during playback. The main display gives smooth scrolling of all MIDI data (including velocities and controller data) and zooming. Unlike other MIDI file players that use hundreds of kilobytes (or even megabytes) of memory for sound samples, our software synthesizer generates audio without any recorded sound; it's only 10k! Song files are also very small (usually under 100k)."
