I think alot of people here started programming on the C64 (in basic?) hehe, well i did. Follow toolchain info on the wiki, and also check some examples on http://ucapps.de/mios8_c.html or http://ucapps.de/mios32_c.html, as well as the many C tutorials online.

Thats great Technobreath, 1.2.8 to 1.2.1 is a huge improvement in version number. change log?

I recently got a Presonus FireStudio Projects. Im glad i went for the 8in 8out rather than something smaller. it also has a stand alone mode where you can use it with out a computer, but you need the computer to set up the different mixes.

Take up Drums... and playing for 6 hours a day. or learn photo shop :P

I am involved in the Blender (www.blender.org) community, and stuff like this happens fairly often. People take the source, change any mention of blender in the program and change it into some other bit of software and sell it. Blender is GPL though, so this is entirely legal. Where they go wrong is by using art to advertise the software, with out permission from the artist, and claiming it was made using the renamed software, which it wasnt. so the images get taken down, they have nothing to advertise with, and after a few weeks the software disappears and everything returns to normal.

Best way to start is design what you want it to look like, in Photoshop or illustrator. (or gimp/inkscape) once you have the layout done, you can start working out how many midibox modules you need.

Hey, estoy utilizando el traductor de google para traducir esto en español, por lo que podría ser un poco apagado. Im la construcción de una pantalla táctil similar a esto en MIOS en este momento. ¿Sería capaz de obtener su código para tener un visita? ¿Está utilizando un cable 4 pantalla resistiva? gracias, Levon Hey, im using google translator to translate this into spanish, so it might be a bit off. Im building a touch screen similar to this in MIOS at the moment. would i be able to get your code to have a look at? are you using a 4 wire resistive screen? thanks, Levon

I have some TLC5940's but im still working out how to get them to talk to midibox, im not that experienced at programing so it might take some time.

there have been some posts on this before Basically the SRIO doesnt update fast enough to do anything higher than 3bit PWM, this is reduced more when doing a LED Matrix. I have some TLC5940 PWM LED drivers, and im hoping to get that working with MIOS, but writing code to drive the TLC5940 is just a bit above my programing skills at the moment. check out these threads: My plan is to use the TLC and a DOUT module to drive a matrix, i have got this working on arduino all ready as it has drivers for the TLC.

You can find most of the information available on the midibox SID on the wiki at http://www.midibox.org/dokuwiki/doku.php?id=midibox_sid Once you have read that, if you have any specific questions we would be more than happy to answer them for you. If you already have 1 SID chip, and can get 1 more, you might be interested in the sammichSID, a kit made by Wilba to make a 2 SID chip synth. http://www.midibox.org/dokuwiki/doku.php?id=sammichSID

For anyone wanting to get some SPST momentary footswitches, i have a bulk buy going

doh, file didnt attach :|

Im going to buy some Momentary Footswitches soon, and can get them for $3 Australian at current exchange rates thats 2.07 euro, or 2.76 USD, If i get 50 or more. PM me with how many you want CLOSING DATE FOR PM IS 23RD OF AUGUST

Seems it is my soldering, I've loaded mios back onto it, and still have the black line. I've tried resoldering the pins and header, no luck, just gonna have to play round a bit more.

Before I uploaded sammichSID, when I turned it on, it showed the top line black for 2 seconds then "ready" but I uploaded sammichSID without the top board on so I don't know if it it showed the uploading info.

Ive finished my sammichSID after some uploading issues (thought the optocoupler was dead..... i had midi input going to break out plug lol) All hardware is put together, besides the Bankstick IC's, SID's and Capacitors for the SID's I've uploaded Setup_sammichSID.hex from the RC37 folder, which uploaded successfully. Now when i turn the Sammich on, the LED's flash a bit (se pic 'turning on', then stop and the following is displayed on the LCD (see 'on') LCD is from Wilba. If i press F1, then one column of LED's turn on. I have sent midi data to the Sammich, and the LED's flash on an off deppending on which notes are played, pressing F3 makes the F1 row flash on and off. Anyone got some advice as to what might be going wrong? cheers

bump... anyone have some more info, im lost at the moment.

a little OT, but... OSC, Is it going to be coded into the MIOS32 so any app can run it easily, ie easy to modify an app that outputs midi to output OSC? will you be able to take the 10bit readings out of the Core and transmit over OSC? cheers.

Ive found a bit of a hack to get around sending Sysex messages via a knob/slider. have a look at the image. Im working on an editor for a Roland TD6V Drum kit, which only uses SysEx. Using the string template, you can make sure the string never changes length. The strSysex updates everytime the Knob moves, so it provides realtime sysex updates. hope it helps.

Ok, no replies, lets try again..... Darlington array's or not? the original BLM doesnt require these, but the protodeck uses ULN28003 darlington array's and BC547 NPN transistor's. i have seen posts where people say you can not provide enough power with out these, but the BLM seems to work with out it. anyone have any input? Original post: Im working on a LED matrix, just standard Red LED's designed in Eagle CAD to go under my Nintendo DS touch screen (when i get it working ) Im using a PIC18f452, custom coding my MIOS app. DOUTx4 board for the LED's and i would rather use an LED matrix than 2 DOUTx4 boards. Have a few questions. 1) the Protodeck uses ULN28003 darlington array's and BC547 NPN transistor's, but the MB 6582 SID doesnt use them for the LED matrix. Are these required? 2) I was thinking of having 2 LED matrices one which is 8x8 red LED's, and another that is 2x8 LED's. is it possible to treat this as one 10x8 matrix? 3) anyone with experience in PCBs, is my design ok? the LED's are on one side, and the resistors are on the bottom. 4) the DIL's pinning for the LED's are not what the BLM code expects, is it easier to change this in the code to the correct order? or by the wires going from this board, to the DOUT board? cheers,

However you may find that the Synth expects non 7bit sysex message.. like my roland TD6V drumkit, to change the sound, has 1024 different values, so it uses 2 bytes to choose it. to change the pitch, also is 920. etc. and somethings may be on/off.

Could i ask what your programming it in? i want to make a similar thing for another piece of hardware, but have no idea where to start, i have done a bit in python, but not the most portable. Edit, never mind i see synth edit. cheers

the MAX5401 look like they will do the job, doing it this way you could probably get rid of the AOUT module and just use digital pins. Im not sure if the DOUT multiplexer would work though... nils?

I dont think motor faders would work, as for MidiBox they have to be 10K linear, and the core requires feedback from the fader. the EHX micro synth doesnt use 10k pots/sliders. http://www.effectsdatabase.com/model/eh/bassmicrosynth has the schematic. However i guess you could use motor faders of 10K linear into the Core, and then output CV from the core and try http://www.instructables.com/id/Make-a-Voltage-Controlled-Resistor-and-Use-It/ for the CV to Resistor.. but its a bit of a hack,i doubt it would work to well.. im sure someone else will know a better way of doing this. you can use a FET to do 0- +5V to control resistance too. Google voltage controlled resistor.
