So, whats new guys?? I've seen FM project has been updated, what exaclty? Laters! Fumi

Hello everyone, I'm about to build the PIC programer for finally burn my 18F, however, looking at the board layout (http://www.ucapps.de/mbhp/mbhp_burner_v1.brd) with eagle, I found 2 strange things compared to the circuit design (http://www.ucapps.de/mbhp/mbhp_burner.pdf), that I want to clear off before drawing the thing into the copper side of my board, these strange things are related to the DB25 connector: -there are several pins joint and going to ground on the circuit desing that are not that way in the board layout. -there's a strange track in the board layout that goes from one of the DB25 pin to nowhere, despite looking like a tree... doesn't look as doing something. Thanks in advance Fumi

Great to see midibox growing more and more!

Reverb is ok, maybe a way to enable and disable it? I think you should join TK and see if both can make a new synth together ;-) so maybe all the swin sid capabilites pops up, this way it doesn't have to be a simple sid simulation but something else, more complex, and less specific, right?

Great! :D What about a pic of the yamaha chips side?

not sure if its that easy to implement, maybe someone with more electronic knowledge could answer us this question. However, even the designer has updated its code some time ago "to better support the TDA1543 DAC". Don't know but it seems far from easy...

2 korgs are too much, 3 its an outrageous number :o I wish synths would appeared like daisys in my country as it happens in France... but that will never happen :-\ BTW, je sais français, j'ai allé au lycée français de Montevideo presque tout les annés du lycée. Je un peut oublié le français mais bon... je peut lire parfaitement et j'ecoute musique trés souvant. ;)

yeah, the special mbsid is what we discussed in the sid section. We concluded that the swin sid was hard to make due to rare components (the TDA1543 is nowhere available)

oh its true, I haven't seen the second one. 2 identical sweet korgs, imagine, you have replacement parts so at least one is going to work for a long time... sorry for my ignorance but, isn't it better to make an external CV to midi converter? or none of these Korgs have CV input? or there's a disadvantage I ignore? ???

LOL, I feel like at home in this forum, I think that with my knowlegde on programming and electronics I could fit better in here. What I'm building is the FM, but if you think the price of shipping the sid alone is low enough, then you are welcome. Still, I want to make the FM first and if I succeed then I would follow with a midibox sid.

Yeah, exactly! Thanks TK However, suppose I want to get out of the computer, can I easily add 2 buttons (? back ; ? fordward) to move through the 128 presets? Also, 2 more buttons to jump 10 more positions so I can reach a preset that is far in the list (ex: wanna reach preset nº 85, I would need to press "?" 85 times, while if there are 10-, 10+ buttons available, I would have to press the +10 button 8 times, and 5 times of the +1 button to reach preset 85 in this example) Or better, a v-pot... but it would need an lcd to see in which preset you are on.(unless you guide yourself with your ear...) Thanks in advance TK

:o That synth is gorgeous. Its a Korg PS 3100, priced 1000 $ ~ 2000$ http://www.vintagesynth.com/korg/ps3100.shtml I would probably tremble too much while retrofitting that thing... and probably do it wrong. :-X

I'm stuck too, its not available nowhere here, nor even in Spain :-\ However, its only a DAC, there should be an alternative... a modification to the board may be necessary tho... Still, not going to give up, with or without a SID, I'm building the FM first. ;)

yeah, they look gorgeous. Usually, I just nail the wholes a little bit, before drilling, so the pick can enter the whole without alignment problem. How is the liquid called in english? (the one that eats copper? I haven't found a good translation, I just call it iron perclorhide but I don't think I got it right)

yeah, that was what I thought, the way the midibox uses the sid is much more intensive than how the C64 uses it. Which makes me suspect it could not work the way it should... Taking that off, the SwinSID designer states that the thing has much more features, like wavetable synthesis and other, but as it doesnt have software support, he says, then the only use you can give to a SwinSID is replace a real SID, at least temporally or for experimenting. It could interesting tho, to make use of those special features in a Special MidiBOX for SwinSID, but of course that dream could be real only if the mastermind of midiboxes is interested ;) You are missing these: 1- People could want to have a synth without having to carry a laptop, and even if there tons of soft plugins available, lone hardware is still hardware. 2- no SID softsynth have the amount of IN and OUT that the midibox SID has. Due to that, you can't achieve in software nor even half the sounds you achieve with the midibox SID. 3- LOL, did I read well? you don't have to program the AMTEL, the hex file is available in the site. Just burn and you have a SID wannabe ready for it. Also the board seems simpler if you already built any midibox. 4-The sound doesnt tell me bad things... it sounds different of course, the filter could not be even near, but again, you still have a synth in your hands, no computer involved and no C64 cannibalizing needed. BTW, the differences I found in the ogg demos....its evident that the SwinSID had its built in reverb turned on during the recording of those. The reverb alone could be a good reason for going for it... I think I could dare... if it doesnt work, then the solution is simple: get a real SID and replace the SwinSID. I could still use it to build the portable sid player.... not as fun tho... Mmm, to buy a C64 internationally, there's no way for me I'm afraid. There's no Pay Pal in Uruguay, but me and my family we don't have credit card btw. Moreover, the customs could ban everything that is introduced to Uruguay making the dispatch a very tedious and costly burocratic process so... I'm limited to an FM box, or getting the AMTEL chip, or, try to get a C64 somehow. I still can get the packages from my mother, since its person to person box and even if they will open it to see what the hell is in there, an old C64 wouldn't be attractive enough ban, specially if its scratched etc. Here, the prices of vintage computers are really high, almost double what the AMTEL chip + burner costs, but however, there are tons of MSX, and no C64 for sale. :(
