Hi, yes,it`s a typo. No new type of Sid... :whistle: All Sids gone! Best regards Greg

Hi Folks, here are some leftovers from my 6582-project. 2x 6582 from Wilba-groupbuy 2x 8581 from an old c64 All sids tested and working! Price is 17,50.- euro/each Mail to : Greg303 (at) Freenet (dot) de THX!

Hi everybody, I`m in for one pcb and a case with frontpanel. ;D THX!

Hi all, haven´t been here for a while.... :-[ Still the same probs on my SID. All diodes(direction) and resistors(values) ok,all voltages ok,still the same display message... Pleaaaaase,give me a hint,guys. I`m really out of ideas... :'(

Hi Wilba, D1_Core1-4 are soldered,also R80 is. Have to check the orientation of the D´s to be sure they are correct. Stay tuned,I`ll be back! ;D

Hi Thorsten,hi Wilba, thx for helping me out here,cool! I checked the schematics and think,this is what I was searching for! But I thought the can-bus has been already implemented in the 6582-pcb??? I´m going to add one resistor and four diodes. Do I have to connect the midi ins of all four cores too? THX Greg

Ok, let`s go out to shoot some trouble... I rechecked all ics to sit well in their sockets,tryed to upload the app again aaaand...it works! Cool... But now there`s a message on the display "sid 1 nor ready" and "can bus errors". What should be checked next? Any hints? THX! Greg

Hi, checksum says ok after each block. I`m a bit confused.... ???

Hi Seppo, jeeez, j11 is jumpered! ;) It connects the core to midi out,doesn`t it? If j11 is NOT jumpered there should be no upload-request be sent,right? Mios-upload or the "change device-ids" app are working without any probs. Greetz

Hi all, strange probs here! Nearly finished my mb6582 and all voltages are checked and fine. So I put in the cores (4x) from Smash,preburned with MIOS and device ids from 00 to 03. My display shows a friendly "ready",the core sends one request after powering up,everythings fine until here. But... ...each time I try to upload the application with mios-studio 7.5 ,all blocks of code are sent and no errors are displayed. But the core doesn`t reboot and the display shows nothing at all. When I switch the unit off and on again,the core behaves like no mios is uploaded and spits out the upload request every 20ms. After uploading mios once again,the display shows "ready" again. What am I doing wrong??? Greetz Brother303

Hoooray!!! I`ve done it and it works!!! My midi-interface was the source of trouble. I got myself another very cheap interface,plugged it in and the preset-upload was a piece of cake,no probs anymore! I´m using this interface here : http://www.thomann.de/de/search_dir.html?sw=swissonic Like I said,very cheap,but it even works with my nord-modular-editor without any problems... ;D

Hi, sadly the documentation is only in german,but the pcbs are silkscreened so it`s easy to see where each part belongs to. There`s a little bug in the envelope-section,but it`s well documented easy to fix... ADSR-Bug : http://www.synthwerker.de/Bilder-WEB/adsr-neu.jpg PCBs are available at www.anyware-instruments.de ,it`s not documented on their site but drop a mail to them and they will etch the boards by order. Here is a partlist,all parts are available at www.Reichelt.de . http://www.sequencer.de/forumsynth/simplesynth/simplesizer4/SIMBES.DOC And this is the documentation : http://www.sequencer.de/forumsynth/simplesynth/simplesizer_anleitung1.html http://www.sequencer.de/forumsynth/simplesynth/simplesizer_anleitung_VCO.html http://www.sequencer.de/forumsynth/simplesynth/simplesizer_anl_VCF_VCA.html http://www.sequencer.de/forumsynth/simplesynth/simplesizer_anleitung_LFO.html http://www.sequencer.de/forumsynth/simplesynth/simplesizer_anleitung_ENV.html http://www.sequencer.de/forumsynth/simplesynth/simplesizer_verbindungen.html http://www.sequencer.de/forumsynth/simplesynth/simplesizer_VCO_tuning.html ...and the shematics : http://www.sequencer.de/forumsynth/simplesynth/simplesizer7.html These are the main infos. Perhaps try to use an online translator like this here : http://www.online-translator.com/srvurl.asp?lang=de Greetz Brother303

Hi all, does anyone here know the "Simplesizer"? It`s an analog diy-synth (CV/Gate) I built some time ago,pcbs are still available,only common parts are used. 2x OSC Saw/Pulse with sync 1x RingMod 1x Noise 1x LFO with triangle and squarewave 1x S+H 1x Moog 24db lowpass 1x AD envelope to VCF 1x ADSR envelope to VCA many ins and outs available pcb: http://www.sequencer.de/forumsynth/simplesynth/simplesizer_base/simplesizer.jpg some sounds: http://www.sequencer.de/forumsynth/simplesynth/simplesizer5.html A frontpanel-layout example: http://www.sequencer.de/forumsynth/simplesynth/simplesizer_base/simplesizer_synthesizer.gif This nice lil`unit together with a mb303 sequencer would be fine! What do you think?

No,that`s not true. The Bass-station,Bass-station keyboard and the Superbass-station are true analog units! The drumstation is an emulation and also the K-station/Nova/Supernova are. ;)

Hi, @Playbo$$: Did you ever built such a unit? Did you ever tweaked a real 303 and compared it to other clones? Did you ever hear a FR777 next to a TB303? If you don`t know the things you`re talking about just let it be,please! It IS a difference,believe me! ;) Brother303

Hi, @x-ten: a 303-clone without the "obsolete" parts with modern/available will never sound like the original. Believe me,I own a TB303,a x0x and two ML303 (v5 + v6). There is a noticable difference in sound if you only switch from the original Roland-vca (BA662) to a substitute vca like the BA6110. Or change the SK30-o and use another j-fet transistor instead,it`ll be different. (...and very soon you`ll end in a MB33-styled TB-sound!) That`s because I find it much more interesting to take the 303Seq and add it up with a Bass-station-styled 2osc synth or an fm-sound engine like the opl3. And it`s easier to desolder these chips than you think... ;) Greetz Brother303

Hi, why another 303-clone? In my opinion it would be more interesting to build a standalone 303-style sequencer to trigger my pulse or bass-station.A-outs could be added as well for non midi gear. What about a standalone sid303? Put in a pt10 with a x0x/ML-like user interface. Or a mbfm303? Using the opl3 as a kind of (powerful) osc with aditional analog filter+vca section. Just some ideas... ;) Greetz Brother303

Hi nILS, thanks you!!! :-* Brother303 ;D

Hi all, one stupid question to make myself sure if I´m doing right : What`s the correct direction for the control-surface leds of the mb6582? -Long leg (anode) to the round side of the silkscreen -Short leg (cathode) to the flat side Is this correct??? Thanks Brother303

Hi, @Wilba : Thanks for posting this here and,yes,my design was clearly inspired by the 6582mb. ;) I took all the panel elements from TKs rackmount-unit and simply matched it to a pt-10. For me it was very important that I had to make no changes on the firmware,that`s not my cup of tea... :P @nILS : Nice one,really! Do I see a sequencer there at the bottom of your panel? Cooooool!!! Greetz Brother303

Hi all, wasn`t able to get a screenshot of my fp out of Frontdesign. But I sent the file to Sasha and Wilba,perhaps they could post it here? Thank you! ;) Brother303

Hi Nebula, lots of information,thank you. Have to read this closely once again... ;) One idea : Since it isn`t planned to put everything on one single pcb,wouldn`t it be cool to divide the pcbs into "control-surface" and "base"-pcb,similar to the mb6582? Greetz Brother303

NEEEEEEEBUUULAAAAAAA, ;D ;D ;D ;D ...can U hear us? ;)

Hi, no prob! I sit at work here right at the moment,but when I´m back home it`ll be ok... Stay tuned! ;D

Hi TK, wouldn`t it be nice for a mbfm v2 to have tempo(midi)synced lfos like in the sid v2? And what I really like to see is a sequencer-option like in the sid v2. 303 bassline with the fm-engine and tr-styled for the drums. Perhaps a double core solution? Only some ideas... ;) Greetz Brother303
