It’s called Avenir Heavy.

The TENORI-ON is a unique 16 x 16 LED button matrix performance instrument with a stunning visual display. For DJs & producers it is a unique performance tool enabling them to perform using MIDI and load the TENORI-ON with samples to jam and improvise within their set BPMs.

By operating and interacting with the LED buttons and the light they produce you gain access to the TENORI-ON’s numerous performance capabilities. The TENORI-ON provides six different performance and sound/light modes for broad performance versatility, and these modes can be combined and used simultaneously for rich, complex musical expression.

And from 18. – 20. April 2008 there will be a hands-on hacking workshop in Berlin-Mitte called hardhack. The preliminary schedule:

Friday, April 18th:
12:00 doors open
15-18 Room 1: wifi access point workshop with Stephanie Lange

Saturday, April 19th:
10-13 Room 1: unzap workshop with fd0
10-13 Room 2: sound and motion triggered photos with Nadya Peek
13-15 lunch break
15-18 Room 1: microcontrollers and eeproms with Daniele Bianco
15-18 Room 2: white noise/RNG/high frequency sniffing with xxxxx

Sunday, April 20th: free day to do what you want.

There is a certain possibility of meeting me on those two occations.

The plan now was to check if the built-in drum pads can be substituted by regular professional pads like Roland’s V-Drum pads. Actually they work like a charm and so we began taking apart the first DD-11.

As you can see, the DD-11’s eight pads are made of aluminum discs covered with rubber. A simple piezo buzzer converts the hits into short current peaks. Commercial or diy drum pads (like this tutorial at the eDrum project shows) work absolutely the same way. For this project, we only want the DD-11 circuitry and will abandon the orginal case, built-in loudspeakers and trigger pads (which we will keep for future projects).

We hurried a little with this first version, so we kept all the internal electronics. When I do the second conversion, I’ll try to leave out the original amp circuit as well. The amp and power supply circuits are a single module and I could not yet figure out what parts can be left out.

The green mainboard is the most important item here. The small board on the right holds the power switch and volume slider. The brown board on top contains the MIDI in/out (left part) and power/amp circuits (right part). We had a little trouble finding a proper case for the electronics. Most commercially available cases are too small or too expensive and we finally settled for a sturdy metal tool case from Bauhaus (diy store) for 7 Euros only.

I’ll skip the build process itself because drilling holes is not really interesting. Here’s a summary of what we did:

• get everything needed out of the original case, desolder everything else
• cut out the original button/display area and reattach it to the board
• solder eight 1/4″ TRS jacks to the original pad connectors
• desolder all original jacks and relocate those needed to new jacks in the case (MIDI out, Audio out)

There’s no way to change settings without opening the case, but Fabian decided that would be okay for know. The device just starts as soon as a power line is connected, always using its “00″ setting with a certain fixed allocation of pad number to MIDI note. The sound to be played on that event will be set on the sampler to be connected to the MIDI out. In the end there’s no use for opening the case.

Fabian dubbed his new spanking red contraption the Triggerlution. Please ask in the comments if you want to know more. I just found this description of a similar conversion (putting a DD-11 into a 19″ rack) on the net. He did what I was also thinking about for Triggerlution v2: Relocation of the keypad area by rebuilding it on a new board.

Basically, NitroTracker will now act as a wireless sequencer for any software (or computer-connected hardware) instrument. I believe this is a first. It’s not the wheel, but the first wireless MIDI sequencer software evar (though you can use M-Audio’s MidAir technology similarly).
Vice versa, NitroTracker now plays back samples via incoming MIDI note messages. I can’t think of a sensible application for that feature right now, but surely the crazy people on the interwebs will put it to good use.

I’m sure there are legal reasons to consider, but I really can imagine that you could sell a bundled DS launcher card pre-loaded with this and other software some time in the future, say NAMM/Musikmesse 2008. Running homebrew and all that diy fumbling can be a little to arcane to some musicians and I guess there always is a target group that just wants a boxed product.

An M-Audio Oxygen8 v2 MIDI Controller (25 keys, 8 knobs and some switches) and a pink Nintendo DS. Yes, pink.

The geek friends’ peer pressure (and the fact that 0xtob made the fantastic wireless MIDI software DSMIDIWifi; basically only that) finally convinced me that I needed a DS too. Still waiting for my R4DS card that will enable me to use all that fine homebrew software, though. Orders from Hong Kong seem to take some time due to the recent earthquake in Taiwan. Until then I have to resort to Brain Age as my only (borrowed) game.

The Oxygen works nicely and came with a “lite” version of Ableton Live which I’m now trying to get addicted to so that at one point I just have to invest the 260 Euros for an upgrade to the full version. Talk about follow-up costs.

So I ordered two AD781s and one AD633 for this ring modulator thing. They are sent from different shipping centers and the single AD633 arrived yesterday. See if you can spot it on the picture. Should I feel bad now for saving $25 worth of chips and at least the same amount on international shipping? I guess not.

I also odered some 555 and 556 timer circuits to toy around with and build the so called Atari Punk Console and similar things. Actually, I do not really need the finished devices, or rather, I don’t know yet what to use them for — like with Lego bricks, the creation is the more satisfying part of the game. That usage may appear spontaneously or not at all, but I like having strange artifacts laying around for visitors to play with. In case of the noisemaking device (I’ll post some pictures in the next days) I will give it away as a gift to a musician friend.

Still in the thought queue of things to make:

• An analogue tape echo/delay. The plan is to hack up four (identical) walkmen and a fifth tape player with a recording head, fix it all on some wooden board and have a tape loop running continuously. Electronics would include switches for the echo depth, basically switching the play heads on/off and a pot for motor speed, ie. echo delay time. Another simpler idea is to use an old double tape deck with one tape loop in two prepared cassette shells, so that audio is continously recorded on deck 1 and played back with a delay by deck 2.
• I recently bought another b/w TV on ebay, a 70s model in an orange plastic case. I want to fit one of the above noise maker circuits inside and feed the output into the deflection coils like in the Wave Vessel/Wobblevision. The sound must not necessarily be heard, so it would be some kind of piece of digital interactive art: A TV with several unlabeled knobs and switches that shows a strange picture you can alter using these controls.
• Another idea from today involves an old 70s turntable, also in an orange plastic shell turned into a new instrument. Besides a speed controller for the motor (to play records at unusually low or high speeds), I would add a small noise circuit like the aforementioned APC and one or two small sampling circuits. These are found in cheap “memo” devices that can record several seconds of audio in low quality. I tinkered with a free giveaway memo keychain once and produced nice aliasing effects by changing the resistor on the small board, enabling ultra-low sampling and playback rates. So the turntable would feature two of these memo circuits to sample audio snippets from the record and to play them back once or continuously. Add some controls to mix the various sound sources and you have a strange sonic artifact.
