Ok, you are always gonna need the bootstrap loader and MIOS. In order to test your display I would then load lcd7_t6963c_v.zip. The Sid program does not support GLCD's. If your goal is to use it with the Sid, (I think) you will need to adapt the code to your display. Justin

Thanks Driftz! I didn't catch that. I'll try it tonight. Justin

Hey I have a question. I only have one DOUT module for my Sid step C. I want to use this for the modulation matrix. I see in the cs_menu_io_tables.inc where I can change the pin assignments for the other LEDs, but the mod matrix isn't there. I checked the cs_menu_matrix.inc file, but I don't see any obvious (to me) places to change this. I want to change the matrix from Shift Register 7&8 to Shift Register 3&4. Can anyone help? justin

If you are working with the 18F just print out page 217-252 of the datasheet. These are the instructions. Also print out TK's macros.h file. Then do like Driftz says and run the examples from the on paper with binary numbers. Then run some examples going through TK's macros. This should help you learn what they do. Justin

Ok, I tried that and it didn't work for me, but I'll try again tonight. Justin Edit: I just tried it again. Same result. It only shows 4 items like it is supposed to, but if I go to the ENV page, and turn the menu encoder to the right, I can't get to the REL parameter. For the record, I am using a panel just like TK's with 5 menu buttons and a menu encoder. Justin

Hey, I was going to sell one of my spare 16x2 lcd to someone building a SID, so I hooked it up to my SID first to test it. I changed the config in the text file to 4 and turned it on. My experience is that it doesn't work properly. I still couldn't get to the last menu item i.e. the release on an envelope. I think some of the menus worked fine - the cfg menu for example. Hopefully someone else can try it on there box. Justin

Yes, I have had to replace about 10 PSUs in my office. Luckily none of the computers were damaged when they blew. I hope yours is ok too.

No I believe he is talking about using a wallwart. If you use the C64 PSU you don't need any heatsinks, all the heat is in the PSU. I don't have any heatsinks on mine, and the regulators don't get hot at all. If you do use a wallwart, then you can buy heat sinks at Radioshack for pretty cheap, or scavenge them from broken equipment. in a pinch, you can even make your own by drilling a hole in a rectangular piece of metal and then bending it into a U: |_| . Installation is just a matter of bolting the heatsink to the regulator with a small bolt and nut.

Hey, I saw this and remembered your question. http://www.bobblick.com/techref/projects/lcdterm/lcdterm.html I don't know if this is of any use. Justin

from:http://www.ucapps.de/mbhp_sid.html Hook the wallwart output to J1 on the core and J1 on the SID as well. The polarity doesn't matter since you have the bridge rectifier. Yes (in my experience) this is noisier than the optimized PSU which I highly recommend. You can use the wallwart to get up and running, and then when you get your hands on a C64 PSU, use it. That is what I did. Justin

Yes these will work. I bought 4 of them awhile back. They mount with two screws (not included). Justin

I would recommend you stay away from the EL ones too. Especially if this is your first project. I have bought a lot of displays on EBAY and haven't had any problems yet. An easy way to find some is to search for HD44780. If the seller doesn't have the datasheet, you can almost always find them on the net. It might take a bit of work, but I have found them on all the displays I have purchased (provided the seller lists the ID on the LCD i.e. Sharp LM40X21B). I think that a 2x40 is overkill for a SID. I think that you would have to modify thorsten's code to display more than 5 items on it. By the way, I have three extra 2x16 backlit HD44780 lcd's laying around that I'll sell for cheap if anyone is interested. Justin

Hey, the first C64 I bought had the sid soldered on it. I thought I could get it out quicker by using a torch instead of unsoldering each pin. Bad IDEA! I thought I had fried it and so I threw it in a drawer. After I built my sid module, I used a different sid, but on a whim I threw the other one in and it worked fine. I guess they are pretty tough chips. I would try it. Get your module working good with your other one and then swap the old one in. I don't think you'll fry your module if the chip is bad. Good luck... Justin

Hey thanks for mentioning this. I have a question: I changed the #define CBM8580_FILTER_FIX 1 to #define CBM8580_FILTER_FIX 0 to disable the filter fix (I am using the 6581), but after reassembling with no errors, converting the hex to sysex, and programming the chip, I don't get any sound out of my sid. If I change it back to 1 and do it again, it works fine. Is this what you did Stigmata?

Hey I just got a T6963C Graphic lcd real cheap. I know this isn't the best display to use but I just want to hook it up and play with it. My question is this: in the power schematic with the MAX759CPD: http://www.ucapps.de/mbhp/mbhp_glcd1.pdf shows a component L1 - what is this? Also do you just supply the max with +5v and ground? Finally, the board that this lcd was mounted on came with a NMV0512SA DC-DC converter, a 7805 and another component labeled NS-206 -I haven't id'd this yet. Can I use this to get the proper bias voltage? Thanks.. Justin

Ok, I'm using a patch that has the wave table sync activated, and I have cubase sending midi clock and midi timecode. I also have a fader on my midicontroler set to CC#120 (wavetable rate). When I play back a midi clip of just one held note, the wavetable sequence is not related to the tempo of the sequencer. If I change the wavetable rate it still changes the speed of the wavetable. Shouldn't this be disabled? Or am I misunderstanding something. Thanks Justin EDIT: Ok, I think I got it working, now the tempo affects the wavetable rate, but it is not locked with the metronome. Is there a certain rate that I must set the wavetable rate to to get 16th notes?

Yes! I am interested in this also. I have set my sequencer to generate midi clock, but changing the tempo seems to have no effect on the wavetable speed. I would also like to know what effect the wavetable rate has when the patch is set to sync the wavetable. Justin

I think I made a mistake. The ain64 test example only shows you how to drive the pots, leds and buttons. It doesn't have any midi implementation. I think your code is correct though. It doesn't matter if you have a dout or not. I think that the only example programs that send midi are the encoder examples and the midi tc box. You might have to look at the encoder examples and try to put similar routines in the ain64 test example. Sorry if I confused you. Justin

See this thread: http://www.midibox.org/cgi-bin/yabb/YaBB.cgi?board=concepts;action=display;num=1062654403 I think until the MB64 18f port is done, you just have to change the text files manually and reassemble the main.asm. I know what you mean about not having a clue. I have just started trying to learn how TK wrote this stuff, and it takes quite a bit of work. Have you loaded the ain64_din128_dout128_v1_3 firmware. This is where I would start if I were you. Justin

This is awesome! Just wanted to let you know that none of the jpgs for the kits open up when I click them (in the order section). Justin

Hey that is a great design! The only thing I might say is to consider using encoders instead of the pots - except the one that is shared with the fader. This way when you change to a new preset, your values won't jump. Also, the lcd looks too small to me for a 16x4 it looks like you have space for a 16x2. I like your idea for the switch to change between the fader and pot. I did the same thing on my first mid box, and it worked pretty darn well. Great job! Justin

Yeah, I was thinking along the lines of TK's handling in the MBSEQ - if you turn the BPM all the way down, it goes to external sync. I thought about starting with the Magic Midi Delay, because it is smaller, and perhaps easier to understand, but I will take a look at the code for the 18f sequencer version and see if that would be better.

Hey I had an idea that might be a good MIOS project: Implement a midi "wavetable" controller that would be similar to TK's cool wavetable function for the SID. It would trigger on an incoming note and then play through the wavetable with the BPM set by an encoder. The controller would go through a list of events just like the SID wave table and send out notes and controller values based on the table contents. The controller would just keep looping through the table until the note is released, or it could be just played through once. It would be able to send out to different channels assigned to different sounds on your synths. I think I will try to make this using the Magic Midi Delay as a starting point. What do you all think? Let me know if you have any ideas! Justin

I can do it for you if you want. That way you can just send me the total amount. Let me know.... Justin
