I would prefer a Yamaha OPL before a YM2149, because the FM concept offers new possibilities (the YM2149 is similar to the SID, but with reduced features, it wouldn't make fun). Since OPL3 and OPL4 are normaly integrated in ASICs or only available as SMD, how about this easy solution? ;-) Best Regards, Thorsten.

Hi, LED-rings and meter bridges are driven multiplexed - this saves a lot of pins :) See also http://www.ucapps.de/mbhp/mbhp_doutx4_ledrings.pdf So: for 16 LEDrings and 16 meters you need 2 DOUTX4 modules Best Regards, Thorsten.

Hi, a resolution of at least 240x32, better: 240x64 is required so that all 55 characters of the host message can be displayed on screen. Currently only one LCD type is supported (see documentation), but more drivers for cheaper LCD types will be written soon. Best Regards, Thorsten.

Hi Kieran, yes, the 512k(bit) == 64kbyte derivative should also work and MIOS allows to access the upper address page. But there is no application yet which allocates more than 32k Best Regards, Thorsten.

Btw.: USB drivers are no problem: under Windows ME/2000/XP, Mac OS X and Linux the standard drivers for MIDI USB have been integrated. The USB device on the other side only needs to send the required USB descriptors to open multiple MIDI In/Out ports (I already tried this by hacking my MIDIman midisport 2x2 interface which runs with a Cypress chip) So - the show can begin once some DIY friendly PICs with integrated USB interface are available. ;-) In the meantime this router will only be useable as mega-merger or whatever. Best Regards, Thorsten.

sure, it can :) But so far as I don't own this chip, I cannot give support. :-/ Best Regards, Thorsten.

Hallo Martin, mit einem Jog-Shuttle habe ich noch nicht herumgespielt, aber zumindest mit MIOS sollte es sehr einfach zu adaptieren sein. Man muss es ja lediglich an vier pins anschliessend, den Status ueberwachen und bei einer Aenderung ein entsprechendes MIDI-Event senden. Die frage ist nur: welche MIDI Events sind von der Host-Applikation (also Traktor, Logic, etc.) dafuer vorgesehen? Gruss, Thorsten.

Using the ICP option while the PIC is also powered by an external supply could be a possible reason why your JDM has been damaged. Ok, since you didn't use this option and used the JDM standalone, since the programmer failed during the burn process, since the MCLR voltage is very high compared to the recommented value, a possible reason could be that you destroyed the internal programming unit of your PIC. But exchanging the transistors to ensure this shouldn't hurt - on the other hand I never heard (from more than 100 users) that the transistors get damaged after some burning processes. Best Regards, Thorsten.

Hi Vybe, today I've double-checked this issue on my MB64 - works ok so far, button numbers 17-20 are the right ones. Best Regards, Thorsten.

Hi Cyril, ok, here my first questions: did you check the polarity of the MIDI plugs (see the MBHP core schematic on the right side)? Did you mix MIDI In and MIDI Out? Which MIDI interface are you using (Gameport?) Best Regards, Thorsten.

Hi Seb, based on the statement in this posting: http://www.industrycommunity.com/ee/ee-2/messages/521.html your display possibly requires a negative voltage at pin 3 (contrast input) However, Douglas Pederick noticed the same problem with his HD44780 display and he found this solution: http://www.ucapps.de/mbhp/mbhp_lcd_neg_voltage.gif http://www.ucapps.de/mbhp/mbhp_lcd_neg_voltage_connection.gif When you study the schematic of the core module, you will notice that some components of this circuit (like the 1000uF cap and the 7805) are redundant. Just inform me if you have problems to build the circuit based on these plans, in this case I will test the circuit by myself and draw a new schematic especially for the MBHP core module --- but it can take some days until I will find the time for this. Best Regards, Thorsten.

Hi Kent, please try it, because it will be hard to get a cheap non-euro size PCB. :-/ Maybe it's better to put CON9 in the middle and to arrange two slaves at the left, two at the right side. The slaves itself are selected over the data bus when A0=1. Every slave has one dedicated select bit. For the slave ID setup I plan to provide a seperate MIOS application which initiates a special password sequence to change the ID. Only one slave should be connected to the bus at this time. The slave will save the ID in EEPROM so that this procedure is only required once. Best Regards, Thorsten. P.S.: although my plans are clear, I don't will find the time to realize this application before May. Other projects have higher priority

Hi Pezkall, an AOUT interface to external effect gear (also Moog filter, etc), accessible via Control Matrix and CC, is planned. :) Best Regards, Thorsten.

Danke fuer das freundliche Angebot, aber erfahrungsgemaess hilft ein Redesign der Homepage oder Menuestruktur nur kurzzeitig, weil sich bei meinen Designs die Fakten, Prioritaeten, Moeglichkeiten, etc. quasi woechentlich aendern. ;-) Um Aufwand zu sparen, moechte ich zuerst die PIC16F Projekte komplett auf MIOS portieren, bevor ich die Homepage Struktur komplett neu gestalte (so dass sie auch wieder lesbarer wird). Gruss, Thorsten.
