Hi Christoffer, random bugs are the worst case... However, I finally found it: the software synthesizer part overwrote the multiplication result registers, this crashed the control surface with a probability of 1:500000000 ;-) Step A3 can now be found under Concepts->MIOS->Download There is still another issue: when you upload a patch to a BankStick via JSynth, there is a (low) risk of dataloss, caused by the MIOS_BANKSTICK_Write routine which takes longer than on the PIC16F. Reason for this is, that the MIOS version also verifies (read-back & compare) the content. Since this routine has never reported a failure yet, I will add a MIOS_BANKSTICK_WriteFast function to the next MIOS version which runs with the same delay like the PIC16F version and therefore solves the upload problem. Temporary workaround: upload the patch twice. MIOS surpresses writes to an EEPROM if the data is equal, this gives the application enough time to correct the missing data which have been lost during the first attempt. Best Regards, Thorsten.

great! :) Best Regards, Thorsten.

Mickey: maybe something for Step Z ;-) I just have updated the MBSID firmware for PIC18F: in the new main page the sound patch can be selected via rotary encoder or inc/dec buttons. The menu is called by pressing any select button. The menu has a new item "SAV" to save (or copy) the patch to the current/a new patch number. Note also that there is a new bootstrap loader especially for MIDIbox SID (and others) which doesn't stall anymore if note events are received during the startup phase. see Concept->MIOS->Download Best Regards, Thorsten.

Search in the web for "yamaha fm" ;-) Yamaha OPL was a very popular sound chip in the early nineteens, supported by nearly every PC sound card. I just have purchased a couple of old soundblaster and galaxy soundcards for 1 Euro each and will evaluate the possibilities in the next weeks - no more info before my first tries. Best Regards, Thorsten.

yes... like it can be found on the SID intro page since 6 months ;-) Best Regards, Thorsten.

Hallo, vor einem 128x* Display kann ich nur dringenst abraten, weil sich auf diesem Display die 2x55 Zeichen der "Host-Message" nicht mehr darstellen lassen. Mittlerweile sind schon drei verschiedene Low-Cost Displays unterwegs zu mir, fuer die es dann bald auch entspr. MIOS-Treiber geben wird. Die Auswahl sollte dann so gross sein, so dass man auch bei EBay mal etwas brauchbares erwischt. Gruss, Thorsten.

Hi Dan, it seems that the three multiplexer select lines @J6 are not in the correct order. Best Regards, Thorsten.

Hi Scott, different things have to be taken into account: ensure that mono or legato mode is enabled (and not poly mode) if the pulse waveform has been selected, the pulse width should be > 0 if the oscillator output is routed through the filter, don't forget to enable LP, HP and/or BP Best Regards, Thorsten.

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.
