Hi Matteo, since your MIDI In is working, you don't need to exchange the CNY17-II by a 6N138. Only the additional line to the LCD is required. And the new firmware of course. Maybe you will notice a better performance with your breath controller, since LCD accesses don't slow down the ADC driver anymore. Best Regards, Thorsten.

This time a question by me ;-) Under Linux I've a small but really usefull tool called "xpaint" which allows me to edit bitmaps for the graphical display very efficiently. It provides a high zoom level of 20 and more and it features a grid view which is very important for editing small characters and icons. Does anybody know a tool for Windows which offers similar features? high zoom factor grid view basic drawing tools (pen, line, circle) text editing two-colour bitmaps optionally export to the .xpm file format It's not for me, but for the users who want to change the bitmaps for their MIDIbox NG. ;-) Best Regards, Thorsten.

Hm, sieht eher nach einem Mix aus Houston und Mackie Protokol aus (oder die Houston Leute haben einfach das HUI Protokol abgekupfert ;-)) Ich selbst werde fuer dieses Protokoll kein "MIOS Application PlugIn" programmieren - bin halt Logic und somit LC user - aber wer moechte, kann es von einer der demnaechst erscheinenden Applikationen ableiten. Gruss, Thorsten.

Fine Ian - it seems that bad solderings are mostly the reason for the fails, so I can only suggest to check the connections again, again, next day again and again ;-) You made a cool panel foil, Dan! Hopefully I will find a similar foil in germany for my control surface... :) I will add the pictures to the gallery soon! Best Regards, Thorsten.

Hi David, All MIDIboxes can send NRPN by using "Meta events" (programmed sequences of MIDI events). However, MIDIbox64 works with 8 bit resolution internally, the max. resultion is 10 bit, but this requires some additional programming effort. MIOS offers 10 bit by default (see Concepts->MIOS->Status) For higher resolutions it's better to use rotary encoders, because more than 10 bit cannot be handled by affordable pots/faders Best Regards, Thorsten.

Hi Rogic, the receive button requests a dump from the MIDIbox (-> MIDI In/Out has to be connected). But I think that you want to send a dump? Best Regards, Thorsten.

Hi Dave, some pictures can be found here: http://www.midibox.org/midibox_lc_photos/index.html http://www.midibox.org/midibox16e_photos/index.html http://www.ucapps.de/midibox/midibox64_foto3.jpg http://www.ucapps.de/midibox/midibox64_mf_inside.jpg (expired design) Best Regards, Thorsten.

Hallo Johannes, gibt es ueber diesen Controller eine detailierte Spec, in der alle gesendeten und empfangenen MIDI-Events aufgelistet sind? Andererseits: wahrscheinlich wird sich die Baby HUI nicht sonderlich von der MC unterscheiden, man muss vielleicht nur die LC_ID anpassen... Gruss, Thorsten.

The old settings have been overwritten as I updated the forum software. However, if more people don't agree with the default settings, I will change them. ;-) Best Regards, Thorsten.

Yes, the LCD should work when you only connect the first 14 pins (ground ... D7). Don't forget to adjust the contrast pot! Best Regards, Thorsten.

Thanks again - yes, the button map is really usefull! Frank has nearly completed the .ini file for a complete emulation. But in the meantime we also found some imperfections, which will not be fixed for PIC16F (due to the required effort), but only for the PIC18F version: All PIC16F MIDIboxes: flashing LEDs not supported MIDIbox64: MSB of v-pots ignored, so that it makes no sense to use pots as encoder replacement. MIDIbox16E: MSB issue has been fixed since the last release, a new release will be done in a few days. Encoders can work with a resolution up to 14 bit now. But only the first 8 encoders, due to memory limitations. A solution for all encoders could be possible, but this would lead to a completely different MB16e variant with a new data structure. LED rings not working correctly. MIDIbox MF: no additional issue found yet As I want to reduce my own effort for this type of emulation (the Mackie Control emulation is working perfectly, and thats the most important for myself... ;-)) the "perfect houston emulation" will only be realized for the PIC18F Best Regards, Thorsten.

When you've experiences with vectorboards, build every module on vectorboards in order to save the money. Mostly I solder my circuits also on this way. Best Regards, Thorsten.

It makes the project status more transparent: http://www.ucapps.de Concepts -> MIOS -> Status Best Regards, Thorsten.

finally!!! :D I hope that it will work again after the next power-on ;-) The LCD issue was just a possible problem, normaly it works w/o problems (my SIDs are running since some months w/o any damage, although one of them is stuffed with a LCD) Don\t forget to provide some new patches! Best Regards, Thorsten.

Yes! perfect! :) Best Regards, Thorsten.

So it's clear now: there must be a weak connection between the +5V input of the SID module and IC2 (possibly the other ICs also). Start measuring the voltage between J2:Vs (ground) and J2:Vc (+5V input). Thereafter follow the two power supply tracks with your probes in order to find the broken contact or connection. This should help! :) Best Regards, Thorsten.

Please measure the voltages between ground and the given pins Best Regards, Thorsten.

This will be possible with the upcoming PIC18F firmware -> see news section :) Best Regards, Thorsten.

Hi RAF, no, thats a graphical LCD which is not compatible. See some threads below for the upcoming solutions. Best Regards, Thorsten.

Ok, your PIC is still working - perfect. With the test firmware, the voltage level of Pin #22 can be ignored. Now check the interconnections between Core and SID module (again) Thereafter measure the voltages on the 74HC595 chips: Pin #10 and #16 of IC2 and IC3: >4V Pin #2 of IC2: >4V Best Regards, Thorsten.

Very good! :) Best Regards, Thorsten.

Hi Rogic, you can use Serge's MIDIbox editor to change the channels. Or you can just upload the "midibox64_generic.syx" example from the mk_syx archive which has been created especially for software synthesizers Best Regards, Thorsten.

Ok, so the 74HC595 shift registers are not serviced by the PIC. Now it's important to know if the firmware is running before debugging the SID module. Here some voltages, which have to be measured against ground: Pin #1: > 4V Pin #17: ca. 2 V (must be > 1V and < 4V) Pin #19: < 1V Pin #20: > 4V Pin #21: < 1V Pin #22: > 4V Best Regards, Thorsten.

Another check to determine if the SID can be accessed by the PIC: at power-on, the reset signal of the SID (Pin #5 of the SID chip) is going low for about three seconds, thereafter it goes to +5V. This can be measured Best Regards, Thorsten.

There is possibly a way to freeze the LCD driver, and thats a floating signal at pin RB7 of the PIC. Dan: could you please temporary remove the LCD and solder a 1k or 10k resistor from Pin #40 of the PIC to ground? If this doesn't help, I will provide a very reduced test program for the SID which *must* work. Best Regards, Thorsten.
