the squarewave parade - bleak mixer v.b

passive analog summing mixer

"this is a very compact four channel passive analog mono mixer with mutes and volume controls for each channel along with a master volume control. it can be used to process either audio or control voltages and it can be used backwards as a splitter. being a passive design means that it does not impart any "color" or filtering of any kind and yes you can use this as an analog summing buss with your computer. it is the same design used in devices costing 10 times as much. being passive also means that it doesn't require a power source but because of that it may require a slight amplification after the main output to bring it back to up the desired level, measuring it during audio use showed a nearly 20db drop in volume, this new version [ v.b ] has less of a drop then the first, and no the mutes do not pop when used. there are different colored TSP stencils used. they are a little slapdash, orange, red and green. the remaining two are just black. cases are powder coated black

::: CONTROLS :::
channel attenuators: reading from left to right are the 4 input volume controls
mutes: diagonal up and to the right is each channel's mute switch
main attenuator: far right knob is the main output volume
i/o jacks: each jack is in line with it's knob "

passive shaker / noise box

"yet another limited run of shaker boxes but this time in ultra compact aluminum cases. only 21 made in this batch with some TSP grid stencils here and there. the paint is baked but they can still be scratched or chipped if you like

there is a piezo element used as a contact mic which i’ve attached to the inside wall using industrial epoxy, then i filled the case with marbles and bb's this time. i think its the best sounding version so far. as usual i've sealed the inside components in black rubber to keep them protected from wear or breakage. it will also work as a contact mic and when placed in front of an loud enough amp it will feedback. no extra controls on this one" more info

"the TEASPOON by tsp

instant playback looping audio sampler

this teaspoon was originally sold in my store but it never reached its home, after a few months of being lost and after refunding the seller it was returned to me.

this is one of the audiobulb limited edition run. only 15 of these will ever exist

the teaspoon is a lo-fi instant playback looping audio sampler designed to achieve the classic glitching / stuttering / skipping effect by pushing a single button. there really isn't much more to say.

i have modded this to include a hold toggle switch (not shown in photo) in addition to the normal pushbutton to keep it looping even after you let go of the button.

SAMPLES and VIDEOS can be found here. forum talk"

"I've recently been commissioned by Dave Formula of Magazine/Visage to build a controller for his Proddy ASB (Magazine have reformed for a couple of gigs here in the UK, and unfortunately Dave couldn't risk taking his Mk1 Oddy on the road). Lucky for me that a mutual friend of ours spotted one of my modulars, and suggested to him that I may be able to do the job...

The keyboard and midi PCB's were taken from a CME M-Key (nice semi-weighted keyboard, but comes with a terribly flimsy and almost, but not quite entirely, useless joystick!) The joystick was replaced with 3 Wheels - two of which, plus two foot pedals, are programmable. Although I have just found a bug which prevents normal control of one of the foot pedals - GRRRRR!!!!

Any problems... Well, quite a few along the way, the hinging mechanism was a bit of a pain, but ended up using a couple of "Side hanging Window friction hinges". Tolexing was fun - though being stuck in a room for 3 days sniffing glue is not advisable : )" via zamise

CHD ELEKTROSERVIS JP4-KBD: Roland Jupiter-4 MIDI Interface

"JP4-KBD MIDI retrofit enables Roland Jupiter-4 to be controlled via MIDI. You can remotely control the keyboard and speed of the arpeggiator by MIDI commands. The instrument works like polyphonic MIDI sound expander.

Features:
* Instrument's keyboard can be controlled manually and by MIDI Note On/Off commands simultaneously.
* The keyboard can be transposed in whole range of MIDI notes.
* Four modes of key priority can be chosen: Last / Higher / Lower / None.
* Tone generators can be tuned by MIDI Pitch Wheel command. The bend range is from 0 to +-2 octaves.
* Arpeggiator can be synchronized with internal tempo generator or external MIDI clock.
* Number of MIDI channel for communication is user programmable. OMNI mode can be chosen, alternatively.
* Default values of all parameters are user programmable - they can be stored into internal memory.

MIDI implementation - reception only:
* Note On / Off
* CC 16 - "Key Shift" parameter setting
* CC 17 - "Key Priority" parameter setting
* CC 18 - "Pitch Wheel Range" parameter setting
* CC 19 - "Arpg Clock Rate" parameter setting
* CC 64 - Hold
* CC 120 - ASO
* CC 121 - RAC
* CC 123 - ANO
* Pitch Wheel
* System Clock
* System Exclusive - setting and programming of all parameters, selection of MIDI channel"
