uclaros is right, for a minimal test surface i mounted 6 buttons and an encoder on some vectorboard together with one 74HC165 register and 8 resistors. Good way to avoid all the wires... (unless you plan to use panelmount switches of course)

You can use J5 on the Core as either AIN (multiplexed or not), 8pin DIN or 8pin DOUT... There is an example under MIOS Downloads -> j5_din_v1_3 (using J5 as digital input).

His info on chip revisions might be interesting to keep... ---------------------------------------------------- SID Chips: Any SID fan is well aware that each SID especially based on year and batch sounds slightly different, thus I wanted to build a collection that offers the sound of each type and have at least two for mono or stereo play and if possible extras in case a chip dies. 6581 R1: the original revisions these are unmarked. 6581 R2: the second revisions these are also unmarked. 6581 R3: the third revisions these are marked with an R3. 6581 R4: the third revisions these are marked with an R4. 8580R5: The revision 5 chip, widely used for midis but also supports some newer SIDs. 6582: these are extremely rare and a bit of a mystery. Some say these were a proto-type for the R5 which oddly is dated before these and others claim these were the R6 but for whatever reason were never released. These use the same filters and settings as the R5. Revision 1 (R1) original chips: The 1981-83 are R1 chips for certain. 1984 are probably R1, but actually could be an R2. 6581:2482 6581:1683 6581:2983 6581:0484 6581:2084 Revision 1 or 2 (R1 or R2) chips: 1984 are probably R1, but actually could be an R2. Unless you are a SID chip expert it's unknown. 6581:2484 6581:2684 6581:2884 6581:3384 Revision 2 (R2) chips: The 1985 unmarked 6581 CBM are Revision 2 (R2) chips made just before the R3 came out. These were hard to come by so I only have two, no backups. 6581 CBM:2885 6581 CBM:3085 Revision 3 (R3) chips: The 1985 marked 6581 with R3 are obviously Revision 3 chips. 6581R3:4285 6581R3:4285 6581R3:4485 6581R3:4585 6581R3:4585 6581R3:4885 Revision 4 (R4) chips: The 1986 and 1987 marked 6581 with R4 are the last of the 6581 chip. 6581R4AR:2286 S 6581R4AR:2286 S 6581R4AR:2286 S 6581R4:3586 S 6581R4AR:0287 14 Revision 5 (R5) chips: The 1988 and 1989 renumbered chip to 8580 and marked with R5 are the revision 5 chip. 8580R5:1488 25 8580R5:0488 25 8580R5:3188 25 8580R5:3589 25 6582 (R6?) chips: The 6582 chip appears to be made in 1992. Because these are ultra rare; mainly due the fact they were never used in commercial computer. Some people have told me this was the R6 chip and yet others say it was a proto-type to the R5, not sure what the truth is. The 6582 uses the same filter and jumper settings as the R5 (so it can ONLY be used in a C64 that contained the R5 and NOT a C64 that was 6581 based). 6582A:2392 25 6582A:2392 25

Does anyone know a good (DIY/commercial) alternative to the Radial X-Amp? This thing converts a low impedance line level signal to a high impedance (high-Z guitar) signal... which i guess is what i need to be able to use stompboxes/guitarpedals as insert or send/return FX. more info about the X-Amp: http://news.harmony-central.com/Newp/2003/X-Amp.html thanks in advance for any help! cheers, Hastings

Firestarter is making LSDJ MIDI-capable... http://www.firestarter-music.de/hardware.htm

... and it's free.

http://www.urr.ca Hmm... looks interesting! A midi generator/convertor/clock generator that can run on old 486 systems under DOS using a SoundBlaster or sumtin. Allows to convert jockstick input to midi data + convert audio into midi (??) And it looks darn sexy! ;D

That is probably next after the ISA bus interface....

Try to rule out that it is your midi interface that is giving you problems. I had a problem with my SBLive and kx drivers: http://www.midibox.org/cgi-bin/yabb/YaBB.cgi?board=troubleshooting;action=display;num=1061838430

Wel ik ben nog op zoek naar een tweede 6581 SID, dus als iemand me kan helpen mag die me altijd een PM sturen... :) cheers!

I have two 6581s: the first one seems to be playing ok. If i switch chips and try the second one, i only get an extremely faint signal, and i guess what i hear is the oscillator running (keeps playing after note off, disappears when changing patch)? Does that mean... it's gone to SID heaven? :'( update: Seems it's pretty dead alright... I tried running audio through the filters and i get lots of pots 'n' cracks and random behaviour if i run the Resonance from 0 to 127. Also i only hear output going through the fillters when "Chn" is set to 123, regardless of the "Ext" setting... It could not be the caps, can it? I'm using the recommended 470pF...

PIC18F452-I/P is the one, you need the "PDIP 600mil" package ones (PIC18LF452-I/P works as well, this is the low voltage type) You can also order the bankstick ICs: 24LC512 or 24LC256 (also PDIP) cheers!

Have fun! ;D

Aan je andere posts te zien is je probleem nog steeds niet opgelost, of wel?

Als je de midibox aanzet, krijg je nu éénmaal "F0 00 00 7E 40 00 F7" te zien? Kan je een ping doen via midiox? Stuur "F0 00 00 7E 40 00 0F F7" via sysex en je zou een antwoord moeten krijgen. Domme vraag misschien maar heb je de contrast pot bijgedraaid? (Ik had van die trimmers met een vijsje en bleek dat ik daar toch wel een tijdje aan moest draaien voor er wat te zien was...) Als je er enkel Mios heb op gezet zou je toch iets moeten zien ("MIOS 1.4 T.Klose" en dan "Ready" geloof ik...)

hiya, Every button must send a different value for Control number (CC) 0x03. Haven't tried yet, but i would expect value to be value 0-7 for pattern A1-8, 8-15 for pattern B1-8 etc. Hope this helps, will check it myself later. cheers

Huh? Awel men neme een 18F Core en ge doe: stap 1: bootstrap loader branden (zie ucapps) stap 2: mios opladen via midi (sysex met midiox, zie ucapps) stap 3: sid app opladen via midi (idem) Poepsimpel... ;D

From the MIDI Monitor page... ;)

1) Maybe this helps to answer the question: http://www.midibox.org/cgi-bin/yabb/YaBB.cgi?board=parts_q;action=display;num=1057652794 2) I've used 2200µF and that seems to be ok. hope this helps

Hmm... well i have the option of building it with a 16x2 or a 20x4... I think i'll go for 20x4 then and adapt the code to shift everything 2 lines down and have some other info displayed on the top rows. If this gets somewhere i'll submit it to midibox.org.
