Hi William, don't know, it will be your job to find a solution ;-) As I already wrote in another thread: the Mackie protocol was designed for stupid slaves, such extensions normaly have to be integrated into the host application Best Regards, Thorsten.

done Best Regards, Thorsten.

Hallo Lemonhorse, die Verbindungen sind ok, allerdings muss im .asm File (bspw. main.asm) noch das ENABLE_AOUT flag gesetzt werden. Letztes Wochenende hat uebrigens ein Bekannter einen analogen Synth (RFE kobol expander) vorbeigebracht, er war voellig perplex, welche Klaenge sich herausholen lassen, wenn man die CV Eingaenge mit der MIDIbox SID ansteuert --- probiere mal die Random Patches (Tip: am besten sind die PW und Filter AOUTs geeignet, da sich der Offset ueber den Pulsewidth/CutOff Regler anpassen laesst) Gruss, Thorsten.

The server was down for ca. 1 hour, reason unknown. Currently a lot of update processes are running, maybe they are doing something against the fails? Best Regards, Thorsten.

Hi Robin, from that what I can see I can only presume that you need to change your workflow. I can see a lot of syntax errors which will (normaly) be reported by the assembler (take a look into the main.err file), they need to be fixed first, the assembler will tell you faster what is wrong (in principle) then I ;-) Second problem I see: since you are trying to implement the whole thing without validating changes step by step, there is a high chance that you will have a lot of trouble to debug the application if nothing works (e.g. if the application crashes). Try to begin with simple extensions and check if your changes are working like expected. Thereafter start to enhance the code in little steps, always check the effects. This will prevent a lot of frustration Best Regards, Thorsten.

Great! (also success stories are welcome :)) Best Regards, Thorsten.

Hi James, thanks for the kind words! :) Regulator: so long it doesn't fail, it's ok. You could mount the regulator directly on the metal case of your sequencer in order to improve cooling. The regulator of my own MBSEQ doesn't get hot, since the core module is powered by a (unregulated) 6V AC source encoders: swap the two cables which are going to the DINX4 module to change the direction Datawheel: I'm not sure, but possibly you have to change the encoder type in the setup_mbseq_v2.asm file from MIOS_ENC_MODE_DETENTED to MIOS_ENC_MODE_DETENTED2 Thereafter rebuild the application like described here: http://www.ucapps.de/howto_tools_mpasm.html Best Regards, Thorsten.

fine! :) Best Regards, Thorsten.

Hi, I think it's the same like for the C64, you can test this by measuring the voltage between pin 14 and 28 when the C128 is powered Best Regards, Thorsten.

Hi Redhead, for motorfaders you have to include the loop into the LC_MF_FaderEvent function (-> lc_mf.inc) Best Regards, Thorsten.

Hi Sebastian, if there is no other volunteer, you can send the stuff to me (not only the PIC, but also the core and SID module) - just write me a mail to get the Packstation address However, before please doublecheck if the loopback in MIDI-Ox is disabled (-> http://www.ucapps.de/mios/bootstrap_sysex0.gif), theafter open "View->Port Routings" and check if the MIDI In data is still forwarded to MIDI Out And please also try to download MIOS with Serge's SysEx Loader Best Regards, Thorsten.

No, you have to use at least one 74HC165 Best Regards, Thorsten.

Maybe the cheapest solution to bring a SID into the box made by David: And Ludos very compact and nice looking MIDIbox SID: More pictures can be found at his webpage: http://www.tatapoum.net/photos/sid/

Wouter just wrote me that he has received a new batch of encoders "Das lange Warten hat ein Ende" :) Best Regards, Thorsten.

You have to change the settings in main.asm of the midibox64 application to 8 (pots) and 0 (no multiplexer), rebuild the application (like described here: http://www.ucapps.de/howto_tools_mpasm.html), and then you can connect your pots directly to the pins of J5. It shouldn't be so difficult - just try it out and you will understand what I mean ;-) Best Regards, Thorsten.

Hallo Dominik, ich habe meine Empfehlung fuer das Pollin Netzteil (weiter oben) korrigiert - schade, dass die Ausgangsspannung absinkt (passiert eigentlich nur bei Ueberlastung, doch da es eigentlich bis zu 1.4A liefert, tippe ich eher auf einen Designfehler) Reichelt PSA 31U-150: extrem teuer, ich weiss nicht, ob sich das lohnt - und vor allem - ob es problemfrei funktioniert. Dann schon lieber ein eigenes Netzteil zusammenbauen (fuer das MF Modul benoetigst Du lediglich ein Netzkabel, eine Feinsicherung+Halterung und einen Transformator, z.B "EL 54/18,8 112" fuer 6 EUR, die Stabilisierung uebernimmt das MF modul). Dabei solltest Du Dir jedoch darueber bewusst sein, dass das Arbeiten an 220V nicht ungefaehrlich ist. Der Transformator sollte nicht frei herumstehen, sondern am besten in das Gehaeuse montiert, und dann erst angeschlossen werden. Nach dem Verloeten des Netzkabels die 220V Anschluesse mit einem festen Klebeband isolieren, um die Gefahr zu vermeiden, dass Du (oder jemand anderes!) irgendwann einmal versehentlich mit der Hochspannung in Kontakt kommst. Fuer das Core Modul benoetigst Du dann noch einen zweiten Transformator, hier bietet sich fuer eine "normale" MIDIbox "EI 42/14,8 106" an, fuer eine MBLC (wegen der vielen LEDs) "El 48/16,8 106" Preisliche unterschiede zwischen den verschiedenen Netzteilen: haengt vom Hersteller, von der Qualitaet und natuerlich vom Innenleben ab. Stecker-Netzgeraete bestehen meistens aus einem Transformator (ptional mit mehreren Ausgaengen fuer verschiedene Spannungen) + Gleich-riecht-er + Elko. Ein Schaltnetzteil enthaelt keinen Trafo, ist aber nicht fuer jedes Geraet geeignet (wie Du bereits gemerkt hast), ein Festspannungsnetzgeraet ist fuer eine bestimmt Spannung optimiert, und ein stabilisiertes Netzgeraet kannst Du zwar an das MF/Core Modul anschliessen, ist jedoch nicht unbedingt notwendig Gruss, Thorsten.

Hi Steve, in MIOS applications the PIC runs at 40 MHz - the external 10 MHz will be quadrupled by the internal PLL. I guess that the name of the MP3 player (nice work) either doesn't know about this feature and uses a 1:1 clock, or that he has some good reasons for a lower frequency Best Regards, Thorsten.

Hi Wise, in the meantime it should be ok to use the "latest and greatest" version Once I've finished the documentation of MIDIbox FM, I will continue with the C stuff. I'm planning a C testsuite (some kind of reliability test) which ensures that the most important C constructs are working, and that all MIOS functions can be accessed Best Regards, Thorsten.

Hi Volg4, in the last years it turned out that especially in the UK it's very hard to find a cheap (online) shop for electronic parts. It's cheaper to order the stuff from the US The simplest solution: order the kits from SmashTV! Extremely good value, and you can get a preburned PIC, too (this saves you from building a JDM programmer)! :) Best Regards, Thorsten.

Hi bount, you are mixing digital inputs with analog inputs. The J5 solution is only for people who don't want to use analog pots - the example is directed to programmers (not for users) You have to connect your pots to J5, there is no other port where you could do this. Buttons have to be connected to a DINX4 module Best Regards, Thorsten.

Hi uclaros, appart from the high danger of destroying other MIDI interfaces like you've already mentioned, I don't see problems. I would suggest 5V DC. 12-15V will heat up the 7805 too much Best Regards, Thorsten.

MIDIbox64 doesn't support motorfaders, but (after a lot of effort from my side), you can use MIDIbox64E as an alternative firmware. This package includes a setup_midibox_ng.asm configuration which matches with the MIDIbox LC layout, and which can drive 8 motorfaders, 8 V-Pots, 1 datawheel, 8 LED rings, 64 LEDs and 64 buttons. LC/MC clone: It's not only the display which makes the difference, it's the whole concept. A MIDIbox64(E) can work independent from a host, you can control any MIDI gear with it. Advantage: very generic approach, disadvantage: a lot of effort to integrate this perfectly into a sequencer software (e.g. if you want to control VST(i)s) A Mackie/Logic Control requires support from the host software. Advantage: perfect integration. E.g., if you insert some VSTs into the channel strip, you will see the parameters automatically on LCD. No need for creating different MB64E setups. Disadvantage: beside of the higher prices for the parts, you are limited to the functions which are provided by the host (see some postings above, where somebody wants to create a grouping function) Best Regards, Thorsten.

Hi Redhead, you could add a loop to LC_ENC_SendVPot (lc_enc.inc) which sends 8 increment events from CC #16-CC #23 so long a certain button is pressed. But I disbelieve that such a function is really useful - let's assume some pans are full-left, some others are full-right, and you want to bring them to mid position. When you are moving a V-Pot which is full-left to the middle, the V-Pots which are full-right will still stay in this position. There is no real feedback from the host (even the LED ring position doesn't always help due to the reduced resolution), this means that you are not able to determine how much a single V-Pot has to be incremented until it reaches a certain position. Best Regards, Thorsten.

Hallo Thomas, in der MIOS Download Section gibt es ein 8x8 Button Matrix Beispiel, das natuerlich auch mit einer 3x4 Matrix funktioniert Gruss, Thorsten.

You didn't mention how you've changed the device ID and the MIDI channel, therefore I assume you made it wrong. Did you try the Program Change on all MIDI channels? Yes, it should work even if no SID module is connected Best Regards, Thorsten.
