BARTON MUSICAL CIRCUITS. SIMPLE CV QUANTIZER. This circuit takes a continuously variable dc voltage and outputs only voltages related to each other musically, using the 1v/octave standard. It utilizes a preprogrammed PIC which is included with purchase of a PCB. It is has a very low parts count, requires no calibration, and is small enough to be used either as a seperate synth module or as a daughter board to be attached to the input of an oscillator or output of a sequencer/s&h/other cv generator.

If you have a rev 2.0 board, here is the old documentation on that.If you have a rev 4.0 board, here is the old documentation on that. Price for 1 board and 1 preprogrammed PIC $14.

Tron is a simple 16 step, 8 part drum pattern programmer.
It isn't as fully featured as others, nor as expensive. It's designed to be small, cheap and simple to use. It also sits well with GorF and Zira. I've long been wanting a drum pattern programmer to drive my Chameleon when it's running the fahrenheit soundskin to drive the TR-808 sounds. It uses one Atmel Mega32 micro to do all the leg work. It has MIDI in and MIDI out, four 7-segment displays and 16 step buttons. I finished coding this over a three week period, with the majority of work being done whilst I was on holiday in late September 2010. The software can be updated via MIDI sysex the same as GorF, so that people without the programmer and compilers can get updates into their sequencer.
A list of features and specifications can be found on the specs page. For images and movies, visit the Gallery page. GORF seq. Available Now! Gorf is a simple 8 step sequencer. It isn't as clever or complex as the Sequentix P3 nor as expensive as certain other sequencers. I was bored one sunday, and wanted to build a simple sequencer I could use to test Defender and other synths I was building. I wanted something simple, small and that only used bits I had lying around, So Gorf was born. It uses one Atmel Mega32 micro, eight pots, ten switches, four 7-segment displays and a handful of other commonly available parts. Since my original concept GorF has become a full fledged MIDI step sequencer with a lot of extra functionality, including step length, ability to send CCs, patterns can be chained giving you 16 steps and there's the unqiue Bank Play mode, letting you play 8 patterns with varying numbers of repeats and varying order.
GorF is now available to purchase fully assembled with a case by visiting the order page. ADASYNTH. Anonymous asked: Any news about the project? Have you had the time to get back on it? Been trying to make a living with indie app development. Nobody told me it was going to be this hard! You can see what I’ve been working on for the last year with a friend at LSD programming. For the last year I have been busy with many other projects; helping start LSD Programming, developing Mac apps, and now working on a hopeful app for iOS.
I have had lots of ideas for ADASYNTH, just no time to bring them to life. This September, I plan on picking this project back up. I want to bring you all the cheapest and simplest modular synthesizer possible. here’s dSeq, touch screen sequencer module i made for a school project, controlling ADASYNTH. features include: - 4 modes (forwards, backwards, ping-pong, and random) - loop start and end points are adjustable - adjustable speed - 2 voltage outputs (same voltage on both of them, for now) - 1 trigger output (x’s mark the spot) Only when I answer them. Introspectiv. Subatomic. Monday 04.03.2006 6pm came home today to find the 9090 PCBs from Trevor came through my mail slot. 2 PCBs and 4 ICs. 9090 boards from trevor arrived I found some nice scans of the PCBs on c0nsumer's 9090 wiki. PCB scans Tuesday 05.09.2006 6pm Recieved group order of original 909 parts from marco.
These should substitute for a few of the modern parts in Trevor's BOM... making the 9090 closer to the stock parts listed in the original Roland TR-909. Parts from the group order... 909 | 9090 ---------------------------------- M5218A == TL072 opamp 2SC2603F == BC549 npn transistor 2SA1115F == BC559 pnp transistor 2SA798 == BC559 pnp matched pair (Q65-66, 80-73, 77-78, 79-82) 1SS133 == 1N4148 diode CA3080 D1469SD 2SC2878 Sunday 06.04.2006 6-12pm Created a sortable/collapsable parts list (bill of materials) based on Trevor's 'official' 9090 parts list. Download: 9090_partslist_ver1.0.6-subatomic.xls Monday 09.04 - 09.08.2006 6pm Put together a group order for the remaining parts for the 9090. Pots/knobs. Curious Inventor. Curious Inventor Forum.

Subatomic worklog. x0xb0x worklog Tues 10.25.2005 6:30pm I happened to be home sick today. Tracking info at the fedex website said the x0x was "on the truck" at 6:30am. After waiting all day, the box of x0x arrived at the front door. x0x was "on the truck" at 6:30am.
Tight pack job, bubble wrap goes all the way around 1st thing I see, some parts are stuffed inside the hard x0x project case. unpack it all, this is it... found the gold tag (plus the invoice) at the very bottom of the box in a sealed envelope. Wed 10.26.2005 7:30am - 9:30am Printed current manuals, fab, user, mods, schematics. UPDATE 8.10.2006: I've done tests with beta 250 up to beta 400, and there is a difference, read the analysis printed manuals. 8:30pm - 10:30pm Unpacked first Bag-o-Parts (pots, knobs, bulky stuff), Organized these into 2 tackle boxes (Plano model #1354-20).
Unpacked 1st bag, big pile of knobs and buttons. starting to process. 1st bag processed, 2 bags to go! Halfway through the 2nd bag, will resume tomorrow Thurs 10.27.2005. Subatomic mod guide. I created this guide to mod my x0xb0x as shown above, it's mostly cut-n-paste from the x0xd0x wiki, with several annotations, parts lists, wiring diagrams, and other clarifications made by myself... Basically I did this so I could have a paper copy while I worked... Feel free to integrate any of this info back up to the x0xd0x wiki. The mods were selected for 1.) simplicity 2.) dramatic effect 3.) ability to turn off and return the x0xb0x back to stock (most important to me was to not lose the x0xb0x sound!).
Total cost of parts are around $20-$30, and for this small amount, we get some nice additions to our x0xb0x arsenal, check out the sound clips While modding my box, I took pictures, which you will find below at the appropriate places Sound Clips (with mostly qualitative descriptions x0xmod2.mp3(good diversity of mods shown here: frying pan insect buzzing zippering, massive distortion, groaning creaking rubber bands demonstrated) Cosmetic: Functional: See my Tutorial on making cables.

(or, "Snuggling with Sandin") --Originally for a lecture at Bent 2010-- Wed Apr 28 14:19:16 EDT 2010 So, Bent 2010 is over, and as such my arbitrary deadline and excuse for spending time and cheddar on this particular device has been pulled. The above are the final circuits I presented with at the lecture. The thing on the right is the "Video Mess Tool". The thing in the back is a color synth I made for Christams 2009. So before finally throwing these guys into the mothballs for who knows what/how long, I made a couple more videos. This might be it for this project for awhile, so feel free to write to me or get on the forum if there's anything else you'd like to know about!
Xoxo, TB Wed Apr 21 22:11:27 EDT 2010 I LIVE! Xoxo, TB Wed Apr 21 10:27:47 EDT 2010 Yesterday the PCBs for the Mess Tool came in and I populated them.

New steps in factory testing procedure.Re-flashed the firmware on 225 Tides (last minute bug fixes, tiring…).Approved final panel design on new module 2, and started PCB layout.
Thanks Hannes! Finished building prototype of new module 1. A few PCB hacks were required because I used by mistake some I/O pins which were reserved for the JTAG interface O_o. Board bring-up status: 75% operational (remaining 25% next week).Tested and packed 250 Volts power modules.Shot the photos of the new modules and updated the site.18 shipments to dealers.Finished assembly of module 3 prototype.

They have been one of my best weapons to use when making sounds. If you have a wavetable synthesizer that can load single cycle waveforms you might find them useful as well.

The new commodore 64, soon to be dismantled 8:00pm-10:00pm Used Thorsten's "optimised" power supply diagram to build something that takes the original c64 PSU and converts it to 14VDC and 5VDC, with an additional low current connection for the case LED. 7:00am-8:00am Finished the power board. The finished power board, converts the c64 power adapter to 5VDC and 14VDC. Installed the power board into the c64 case, nice fit, you'd never know it's not a c64 inside by looking at this panel... 3pm I ordered "waldorf" knobs from albs.de (Germany), part number 863062.
