Foona

Thanx guys! But it would have been really hard without the support from this forum. I bet you allready figured out im having fun, filling those banksticks with presets. I'ts like i have too much memory..... And still it would be cool to double the ammount of banksticks :P Smithy: Yes those poo coloured ones, as you put it so nicely are not very attractive. I found these green ones at a electronics shop in neighbouring town here in Sweden. They have em at three sizes and they don't cost too much. Easy to solder and cut, and also...they are [glow=green,2,300]green[/glow] :) <edit> Cr*p! Im out of 6581's and thats a real pain in the bonker. One of my SID has a dead bass engine. All i get from it is highpitch noise. I did have one more chip. Bass engine worked, but audio output level is to low. I had to use almost 70 dB's of amplification to hear it haha. But the darn thing works and thats gotta count for something ;D

Thanx guys! ;D Buhler: i can't wait to see your SID! "Luke...(trouble breathing)...i am your mother!"

You should try getting bugfight to slap you. Thats hot too mmm ;)

Im finished with my SID! : ;D Pictures I should have been more carefull. I coloured the case using a spraycan. It turned out well, though i forgot about the clear coating..... The case gets kinda sticky when it's hot indors...like today.. Dust and other stuffies attaches itself to my precious case...not very smart. Iv'e also managed to scrath the case..but i wont show that :P Bottom right picture, one can see how badly i cut the panel for theLCD'n. Not very nice. I've exchanged the original red LED with an amber LED. Goes together well with the silver knob. :) Despite all the mistakes im satisfied. It both sounds and looks raw. mmmm...... There is two 6581's in my shebeast. I recorded some sounds yesterday...but it was boring. So i sat down yesterday and produced this little thing. Israeli Psychedelic Trance inna Astral Projection style. Been a few years since i used to produce stuff like this, but it turned out pretty well. Name of the song is "Mosquitos" and it is aprox 7 min long. The Mp3 file is at 128Kbps and it is about 6,6 Mb large. It might be a bit bassy.. Sounds in the song comes from my SID and moog emulators from Scope Fusion Platform (SFP). Drms from SFP to. Voice synthesis from Analog X say it. And the song is right here: Foona - Mosquitos Thanx everyone for helping me accomplish this! :-*

This was my solution to :) I hate roughin it up with bonehead plugins.

Slowly means more time for perfection! ;D

I do realize that emulating the SID will never make it SID. But thats not why im building it. 1. Building is fun 2. It can emulate SID 3. It's cheap 4. It has more waveforms 5. Building cheap stuff with more waveforms is FUN ;D Same here. What version of Cubase are you using?

Are these the right AVR's? ATmega8515

I can understand that stuff like this takes alot of time. You have my fullest support, cuz i know i ain't gonna get dissapointed, the day im finaly holding one of those boards in my hand.

I see. Well i do love the 6581's too. But when performing live, i need more puch in the filters. Im gonna try installing 8580's and see what happens. Either way, this is the first MbSID iv'e built. And even if the 8580's have more puch in the filter, this one is going to stay 6581. The next one i build will have a wooden box, 6582's and a full controll surface. <edit> even if the filters sound a bit "tiny"..damn i love the sound of the beast. She's just perfect. ;D Gotta go assemble the case now.

That doesen't matter. I was placed in a borg maturation chamber at the age of 5, and internet was hooked up into my brain with elektrodes. For 10 years i was fed information about bakery, history, science and the mating rituals of bugs. I tell you, when they finaly cracked that chamber open, i looked like a bag of sh*t with legs. And if anyone doesen't believe me i can assure you, i am not sick, just special. :P ..and oh..you need school for some stuff. But the internet itself, is also like school. All the information of this world available with just a few clicks. So don't worry. And if it doesen't work out, i can tell my drone neighbours to stop by on their way to assimilate Risa, to install an ocular inplant in your head. Will make you read stuff faster.

Yes the word ass is really beautyfull isn't it. Back to the beast... Iv'e been sitting just playing around with the shebeast, and I get filter response, but no way as near as in the sound example at this page: http://www.ucapps.de/midibox_sid_manual_l.html Under the section "FILter menu". What type of SID was is being used in the sound example. Cuz that sound example is extremely fat! My 6581 SID(s) sounds like this (resonace maxed out, tweaking cutoff): Clip5 Iv'e tried two 6581 SID's and they both have these "tiny" filter responses. Though the 6581 im using now has a much higher audio output. I nearly blew my speakers! For those who have more SID experience. Are my filters shot, or does the 8580/6582 have better filters?

I see........ ..Would you care to elaborate?

Seems i cant stop making an ass of my self. ;D

"Sig rule #7"?

Ah! ;D --- Iv'e been playing around with my beast and come to some conclusions. 1.The 6581 im using now has a dead filter. Really nothing i can do about it, just wanted to share this uncomfortable fact ;) 2.No sound out of the Bass engine. 3.Iv'e got loads of latency when using the Multi engine. I have no idea what's casing the latency. No problems at all playing Lead engine. 4.Regarding the Drum engine. say im playing BD1. I then change parameters. Playaround some more, then suddenly sound dissapears. All other Drum instruments play. I keep playing drums then suddenly SD1 dissapears to. --- Regarding the volume. This isn't really a flaud functionality. Just very annoying. In the settings the volume it's maxed out. And i just don't think it's enough. "Damit scotty, give me more power" Iv'e googled for schemtics concerning "volume boosters"/amps. But most of the curcuits i found is either big and bulky or very noisy. And some have both of these traits. Anyone here who has implemented a prefeable noiseless volume amp into their SID machine?

Thanx nILS! ;D Ah =) Im on it now. Thanx for the advices! <edit> I just noticed you avatar hahaha ;D Any special reason? <edit> I've exchanged the 24awg cables for a shielded HiFi cable for the audio output. And iv'e moved the audio output as faar away from the power cables as possible. Result: Clip4 But i still have a very very low output volume. I had to use the preamp in my Focusrite VoiceMaster Pro, to give the signal a full 60+dB boost on the input. I also added a full 6+dB on the Focusrite output. And still the signal is a bit low. Is it like this for everyone? <edit> wait...before you answer that, i'll check on the volume settings first.

Thanx Buhler! Im am shure that you and many others here understand perfectly what im feeling now. Well celebrating is over. Now it's time to even out the rough edges on my beast. In this topic further back in post #57, i uploaded this Soundclip, and it contained noise. This was when my SID stoped playing sounds. The only sound i got was this noise. At that point i realized i had forgotten to put in that last 2200uF cap, between Vs Vc at J2 on the SID module. I corrected this error. But the background noise did not dissapear. I've got three soundlips here for you: This one tells me every thing is fine =) (exept for the background noise) First the init *blips*..then wait a few seconds...then a melody. Clip1 This is just the same melody with my own first lead preset. Nothing fancy..added some chorus and delay. Oh, some drums to. Drums come from the Scope fusion Platform. Clip2 Here one can hear whats going on in the background. And those two sound spikes in the beginning is me changing presets with the encoder. The clicks don't bother me. This is a SID trait right? Either way, I don't like that sound from the background though..... Clip3 Well, the background noise in clip3 is there from the moment i turn the beast on. And it stays there untill i turn her off..reluctantly...me..turning..her off.. ..i don't like doing that.. Anyone here that might know where this sound is comming from?

Iv'e been over to my friend now, and he had a look at my curcuit. He couldn't see anything wrong with the circuit either. So we started measuring, and we got random voltages. He got so irritated he threw the curcuit in the trash.. Well the story doesen't end there. He pulled out new components and gave me a protoboard. He then told me to make the curcuit while he was watching. It was somewhat embarassing.. After completion we checked all the voltages, starting with the C64 PSU and forward. Then came the BIG one. Measuring between 14+ and GND. And the result.. 14VDC Now that this is corrected i'll hook it up and try to get some noise out of my Shebeast. I want to thank all of you for your support!

14 volts...at a 14 volt output....you must be joking.. :P

Iv'e rebuilt the OPT curcuitry, and now i did it so it looks exactly like the C64 OPT schematics. Now im reading 5.23 volts between 14+ and ground. What voltage am i supposed to read here? <edit> For the fun of it i tried swapping the 9V regulator for a 12V regulator.. Im still reading 5.23 volts.............. Ok thats it! Im giving up. Im gonna go bang my head into a wall. And then, if im still alive, im gonna call a friend of mine. He's an electronics expert, and if i let him compare the schematic against my curcuit, just mabye he'll be able to tell me whats wrong. He can't be blind too.

Im not. Im feeding it 9VCA. The right pins of the C64 PSU are connected to the rigth pins on the OPT cuircutry. Iv'e checked probably hundred of times, and im still checking the connections, every time i measure something. Thats why this problem im having so confusing. It doesen't make any sense. I must be missing something. I didn't. I used the original OPT schematic when building the curcuit using a protoboard. In the end my protoboard looked different from the OPT curcuitry. And just to make it easier for others to see what iv'e done, i wrote a schematic on how my curcuit looks. :)

Regarding the Bridge rectifier, would this do? B80C1500R

Thanx for the pointers! I'll try it out. hehe drawing error i can assure you.

..ok im almost at the point of surrendering to this project.. Im in need of your eyes. Sometimes you do so much stuff, you get completely blind from it. Even the most obvious mistakes can be overseen. You have all been very helpfull and patient, i admire and respect that. So please have some more patience with me. Iv'e made a drawing of the OPT cuircutry that I have made on a protoboard. Is there something wrong with it that i am unable to see? The red connections are wired on the top side (component side) of the protoboard. The black connections on bottomside (copperside). NOTE: diodes are regular 1N4148's. and the Electrolytic for the 5VDC is a 25v instead of 16v. This is exactly how i have made my curcuit.
