I read about tinning your homemade PCB yesterday. This guy used a iron, mounted upside down and this paste used by plumbers to solder copper pipes. It is made of grinded tin and lots of flux I think. I'll post the link whe I find it. Greetings Michael

Hi! I can confirm that. Toner transfer is dead easy once you have found the right paper. For me a simple page from a glossy magazine worked best. Another trick is to sand the copper board (I thinked I used 400 paper) and to wash it faithful with soap so that any copper particles are washed out. Otherwise the toner won't stick to the copper. Another thing I confirm is that Fe03 etching sollutions leaves a green stain. Spilled a little and now some tiles are colored. Never mind. I believe it is the dissolved copper which causes that. Which program did you use to design your board. Looks very cool indeed. Do you mind if I make a 8 by 8 grid for my monome clone. My first lights out should arrive next week. regards Michael

Hi! Is far is I know NI's Traktor only supports 7bit midi signals. But I realized that in the typical +/- 8% pitch range this is sufficient. Nevertheless I included extra fine pitch up and down buttons in my box for even smaller stepped pitching. Best regards Michael

Hi! Du könntest einmal die original midibox64 firmware reinladen um zu sehen ob wirklich alles korrekt angeschlossen ist. Die Schalter dürfen kein Problem sein das ja das System jeden zustand weitersendet. D.h. zB Note on wenn taster offen; note off wenn taster(/schalter) zu. Was du noch kannst (solltest du ein Display haben) ist ein MIOS_Print_xxx einzufügen das dir sagt welcher Taster gedrückt ist. Grüße Michael

Hi! As far is I know traktor can only handle 7bit singnals. It works ok for setting the pitch in a +/- 8% range (typical sl 1210 range). This setup gives you 64 steps in each direction which equals 0.125 % pitch 0 + 0.125 * 64 = 8 (%) 0 - 0.125 * 64 = -8 (%) This might not be as exact as for example Numark TTX-1 (which feature a display so I can tell) and are able so in/de-crease the pitch in a 0.1% grid. [in my opinion technics suck in this aspect, but hey they are 25 years old] I can't tell if there is a second digit internally but I guess not. For finetuning I included a set of two pushbuttons on my traktor controller to increase or decrease the pitch in even smaller steps. Rotary encoders will work for setting the pitch but you need to write a C programm which translates the encoder movements to up/ down midi singnals (you midibox needs to emulate push button hits for positive encoder rotation and negative and you need to assign two functions in traktor). Otherwise you would end with an 0-127 value which is not worse or better than the analog values coming from a pot. See this thread for the code of my traktor box. http://www.midibox.org/forum/index.php?topic=3852.0 ->page 2 I used the encoder trick for pitch bending in my box but this should also work for setting the pitch as well. Regards WW

Hello everybody! Update time again! Finished the c code for use with the C interface. Includes now a working pitch bend and shuttle ring (see first post) sollution. A so called shift button is used to give the encoder and the shuttle further fuctionality -> shuttle_x_alt Faceplate is also finished and sprayed. Pictures will follow. regards M. /* * MIOS SDCC Wrapper * * ========================================================================== * * Copyright (C) 2004 Thorsten Klose (tk@midibox.org) * * ========================================================================== * * This file is part of a MIOS application * * This application is free software; you can redistribute it and/or modify * it under the terms of the GNU General Public License as published by * the Free Software Foundation; either version 2 of the License, or * (at your option) any later version. * * This application is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Hi! Es gibt einen mod für Soundblaster Karten wo man dann mit 2 Tastern lauter und leiser stellen kann. Es gibt dafür Eingänge an bestimmten Soundblaster Karten. Link hab ich leider keinen -> google. Gruß M.

Hi! I invested a couple of days to dig into the C interface and the midi protocol. First of all I want to excuse for the false alarm about the wind bug in T3. Is is still there and very anoying. But I came up with another sollution than sending a reset signal to T3. if (incrementer < 0 && encoder == 0) { MIOS_MIDI_TxBufferPut(0x94); MIOS_MIDI_TxBufferPut(0x00); MIOS_MIDI_TxBufferPut(0x7f); MIOS_Delay(25); MIOS_MIDI_TxBufferPut(0x94); MIOS_MIDI_TxBufferPut(0x00); MIOS_MIDI_TxBufferPut(0x00); } You need to set two midi functions in T3. Deck Tempo Bend [glow=red,2,300]UP[/glow] and [glow=red,2,300]DOWN[/glow] So each time you turn the encoder an note on is sent. But different ones for each direction. After the delay (In my case 25ms) the note is sent off and the motion is stopped. This gives kind of "stepped" feel put it sufficient for beatmatching. You could decrease the delay put you would need to turn your encoder more often. I'll post the code of my full T3-Box in the next days since also programmed a sollution for the alps Shuttle rings. Regards Michael

Hi! I would be interested in 100 pieces. Thanks Regards Michael

Hi! I think I didn't explain very well what I want. I copied your code into the C skeleton, compiled and loaded up. As I understand in your app the Encoder is connected to the pins 2 and 3 of the first shift register und the activate button to the first?!!!!? When I turn the encoder it stays a 64 so I presume the activate button hasn't been pressed. Where can I define where the encoder an the buttons are attached? Regards Michael

Hi! Just checked again. And it works. I'm using an alps fader with an notch at 64 so in can tell that it is right in the middle. Also checked with the display and it says 64. Traktor starts to wind when reaching 67 or 60 in the opposite direction and does not keep increasing the speed. You can even set the wind to around 86 and it keeps playing along just like you would have hit play. Application is MB 64E without any modifications. Had anybody have luck with the code postet in this thread? It just seems that I can't figure out how to set the activate button. regards Michael

Hi! Just wanted to announce that the Traktor wind bug is gone. Just tested it with a regular pot. The track doesn't move any more when the wind is set to 64. Traktor Version is 3.0.2.098 Regards Michael

Hi! Just one hint. Check out traktor 3 before cutting your frontpanel. You will definitively want to include controls for the filter section. m.

Hi! Take care as the 1210's pitch faders are linear but not 10k ohm. These are 20k. I know this because I was messing around with a broken technics the other day. Regards Michael

Hi! The backlight is connected to the supply voltage via a resistor and a transistor and not to an I/O of the pic. Therefore the backlight (I am speaking about the led backlight here) can't be turned on or of. But I am sure you can get the letters to blink. Another way would be to to connect the backlight to an output of the DOUT Module. But I think this can only be done with the help of another transistor since the DOUT is not able to drive the backlight. Regards M.

Thanks for your PM and thanks for the effort you put in this. One question, though. Do you think that is possible to automate the "wind reset" procedure by sending the reset signal after a certain amount of time when the encoder has not been touched? Which traktor version do you use. Has Native Instruments been informed about this bug? [Hmm. I think I need to learn C ...] Thanks a lot. Regards Michael

Hi! Just wanted to bring this up again! Has anybody had sucess with this code? Is development still going on? Regards Michael

Hi! Have you made any progress. Can you show some pictures oder ideas? Regards Michael

Hi! Get yourself an ohmmeter and check all resistors on the DIN module. Had also random midi events which turned out to be faulty resistors. regards Michael

Bought a Midisport UNO yesterday for about 40€. It is very small an neat and I feel a bit guilty for breaking it apart. However....it contains only 2 chips. 1 optocoupler and one of these http://www.stmicroelectronics.com/stonline/products/literature/ds/5521.pdf in an M-Audio OEM Version. The pcb itself is only 60 by 25 millimeter so it will fit pefectly inside my box. First had a bit of trouble because the midisport wouldn't like my front usb port but after plugin it into the back of my computer and updating the driver it worked. http://stud3.tuwien.ac.at/~e0327352/ Pictures on my website Regards Michael

Hi! I would be very happy if someone could code something for the shuttle ring. I started experimenting with 74HCxx chips (Inverter and NOR) to get direction and position. Not very elegant though and space consuming. I am no assembler coder and don't know how much effort this would be. I am thinking of emulating a pot with the shuttle (with jumps of course) Regards Michael

Danke erstmal für die Antwort! Ich hab mich aber glaub ich missverständlich ausgedrückt. Wenn MIOS bootet stehen alle Regler "intern" auf 127 (wie auch auf dem Display). Sobald ich an den Encodern drehe geht der Wert nur runter (<127). Weil weiter rauf geht ja nicht mehr Ich hätte gern wenn MIOS bootet das die Werte auf 63 stehen und ich mich dann von dort nach oben oder unten arbeiten kann. Eine zweite Frage ist aufgetaucht. Jeroen hat das hier programmiert: http://www.midibox.org/forum/index.php?topic=5794.0 Leider werd ich nicht ganz schlau wo ich den Code reinkopieren muss damit das funktioniert. Weil das ist genau die letzte Funktion die mir auf der Midibox noch fehlt. Danke nochmals. Gruß Michael.

Hallo! Kann mir jemand sagen ob man den Startwert von Pots oder Virtuellen Pots (Encodern) einstellen kann. Normal ist es ja so das alle Regler bei 127 starten. Ich hätte aber gerne das sie genau in der Mitte starten weil sonst hab ich immer Sprünge drinnen wenn ich den Pitch an meiner Traktor Midibox einstelle. Danke. Michael
