puddingbrumsel Posted July 17, 2007 Report Share Posted July 17, 2007 Hi TK!Nice to see you testing the Swin ;D Do you think it's worth to build the swin as a 1to1 replacement and wait for further updates ?What do i need to burn the firmware ?I ask because i'm using a not fully working SId (mentioned in a early thread @german) and before searching eb** i would try the swinsid. It looks promising also without any special functions.best regardsChristian Quote Link to comment Share on other sites More sharing options...
TheAncientOne Posted July 17, 2007 Report Share Posted July 17, 2007 Not got time to try this, but there is some AVR Moog filter code in the latest version of AVRsynth fromhttp://krue.net/avrsyn/ there are samples on the site. This might be patchable into the SwinSID. I have the AVRsynth board up and running, but I can't do any panel work until some other stuff is clear, so I haven't done more than a functional test. The filter samples are a lot better than the original AVRsynth filter.My long term interest in the AVRsynth is to split it into Master/slaves and make a polysynth.

swinkels Posted July 17, 2007 Report Share Posted July 17, 2007 I have used a simplified avr programmer like this and It works very well. http://elm-chan.org/works/avrx/stk200.pngThe new avrsyn filter is quite good, but too bad it is noisy ( probably 8 bit calculations ) I will try to port my own implementation of lowpass filter from SwinSID2 to original SwinSID soon.

puddingbrumsel Posted July 19, 2007 Report Share Posted July 19, 2007 Hi Swinkels!Does this mean you are working on a new version of the old SwinSID with only 3 channels ( like the original ) ??OK. the atmega adapter should be no problem but what software do i need to transfer the firmware ??

swinkels Posted July 20, 2007 Report Share Posted July 20, 2007 PonyProg is a very nice program for flashing AVR. Yes, i will try to add more new features to standard SID emulation instead of pseudo-reverb effect. I will release new firmware this weekend with following changes:- Linear Attack support - Logarithmic Decay and Release- 2 x oversampling instead of interpolation- No reverb effectAfter some testing from you I will implement a lowpass filter soon.

swinkels Posted July 27, 2007 Report Share Posted July 27, 2007 Here you can download and test the new firmware with features as abovewww.swinkels.tvtom.pl/swinsid/swinsid_20070727.hexTK already tested it and found some distortions with high frequencies but in most cases it should work fine.

swinkels Posted August 3, 2007 Report Share Posted August 3, 2007 While playing high notes with full spectrum waveforms like sawtooth and pulse you can hear some harmonics. , but this is a standard effect with simple wavetable synthesizers. I am still working to improve sound quality and add new features to SwinSID with help and testing from TK. When I finish we will release music demos and comparisions, so please be patient Quote Link to comment Share on other sites More sharing options...

nebula Posted August 20, 2007 Report Share Posted August 20, 2007 I guess the wavetable-related harmonics on high notes sound like aliasing? If so, I'm just imagining an acid-type line (bassline engine) played using high notes on an unfiltered SwinSID - it could sound pretty trippy. :o :o :o Quote Link to comment Share on other sites More sharing options...
puddingbrumsel Posted August 29, 2007 Report Share Posted August 29, 2007 how is the fusion going ??is it possible to run the swinsid mono like the orig. SID ?? and what parts do i need therefor ?? Quote Link to comment Share on other sites More sharing options...
TK. Posted August 29, 2007 Report Share Posted August 29, 2007 Don't worry, development is still in progress; Swinkels sends me a new firmware almost every day!!! :)I'm sure that you would be frustrated, if you would have build the circuit based on the schematic of two weeks ago, just to notice that it isn't compatible with the future firmware anymore.I can already bring you down from the illusion, that a 100% accurate SID emulation cannot be expected.An AVR is not a Pentium, sample rate is low and it is impossible to oversample the sounds often enough to eliminate alias effects. So, for everybody who wants pure SID sound, keep searching for the original......and use SwinSID in addition! :)Main advantages of SwinSID: - you will be able to access a wavetable synth with the mighty MBSID V2 engine! - no ADSR envelope bug - more waveforms - Swinkels is planning to add FM and Morphing effects - a fat and --> dirty <-- filter! - nobody prevents you to add analog circurity in addition!Since I'm currently more busy with testing SwinSID than writing demo tunes, I'm not able to give you some typical chip effects and tunes which can be realized very easily and which sound very similar to the SID.Therefore I will just give you an untypical bassline (created with the Lead engine) just to demonstrate how cool the filter sounds since about 3 hours :)-> http://www.ucapps.de/mp3/swinsid/swinsid_preview1.mp3Note that this is not a representative demo - SwinSID is not just an "additive synth emulation", the potential is much higher!Some hardware related info:please wait before buying the stuff - as mentioned above: specs are not stable yet.Meanwhile I've switched to a PCM1754, which is a pretty good audio DAC (normaly used in CD players).I especially like the de-emphasis options, which adds some crunchynessBut this chip has two disadvantages: like the TDA1543 it isn't produced anymore (Farnell and Digi-Key has some in stock see findchips.com), and it's a SMD part. But it shouldn't be too difficult to solder, even for beginners.So - if you want to support design, please help to find alternative solutions. Second fact: yes, there will be a PCB. Swinkels just suggested today to use two AVRs instead of one, since it would only cost you 2 EUR more, but would bring so much more...Of course, everybody who is interested could already join the beta testing process - just build the circuit given at Swinkels homepage. If you are not able to find the TDA1543, search for the PCM1754. The pin mapping and audio output circuit is described in the datasheet.Another tip: the 24 MHz crystal "24,0000-HC18" from Reichelt cannot be used (it's a 3rd overtone crystal) - just use an integrated oscillator like "OSZI 24,000000" instead.Please be patient, and don't bring us into pressure - something really cool is growing up, and this needs time! :)Best Regards, Thorsten.

puddingbrumsel Posted August 30, 2007 Report Share Posted August 30, 2007 Good morning TK!Nice to see the project growing. There will be no pressure, because most of us are still looking for the original SID. But i like the idea of an independent SID-like synth. "Cheap", dirt and "lofi" with the advantages of a real synth is just what i want.best regardsChristianps. found some TDA's over @segor.de Quote Link to comment Share on other sites More sharing options...
stryd_one Posted August 30, 2007 Report Share Posted August 30, 2007 a 100% accurate SID emulation cannot be expected.Fine by me :D It's great so far, just the way it is!Swinkels just suggested today to use two AVRs instead of oneOhh yes please ;D Quote Link to comment Share on other sites More sharing options...
Sasha Posted August 30, 2007 Report Share Posted August 30, 2007 Swinkels, TK, take your time. I don`t believe we are in hurry. I`m sure we already have more projects on "do to" list than we have time to build it.Personally I don`t expect exact SID emulation at all, more something new, different. And what swinSID advantages sounds really great. Now that Wilba is selling 6582`s and those nice PCB`s everybody can build one even if no C64 around.Semo sounds really great, I wish there are few more, but please don`t make it if you don`t feel like. Better spend more time developing. :) Looking forward to see the fruits of your collaboration. ;) Quote Link to comment Share on other sites More sharing options...
Jaicen Posted August 30, 2007 Report Share Posted August 30, 2007 Sounds to me like it's growing into quite a chip project! I wonder when you mention wavetables, could it produces results like the Elba Monowave? If so, that would be awesome! I know that uses a moog style filter rather than a DCF, but I think I'd prefer the nasty aliasing you get from the DCF. There's all manner of smooth sounding synths, who needs another Moog clone ;) Quote Link to comment Share on other sites More sharing options...
cube-c Posted August 30, 2007 Report Share Posted August 30, 2007 Another tip: the 24 MHz crystal "24,0000-HC18" from Reichelt cannot be used (it's a 3rd overtone crystal) - just use an integrated oscillator like "OSZI 24,000000" instead.Ah, that's the point. I built one using this crystal type. I made a test in a c64 and swinsid outputes only random noise. So I have to replace the crystal with the osc...

Therezin Posted August 30, 2007 Report Share Posted August 30, 2007 TK, you're right - that filter is filthy.I need a shower.And a SwinSID. Quote Link to comment Share on other sites More sharing options...
Shadyman Posted December 6, 2007 Report Share Posted December 6, 2007 *bump*How goes the SwinSID work? Can't wait for the SwinSID modules :)Any chance you could post the unassembled code with it, too? I'd be interested in trying a dsPIC version, (16-bit pic, filters, and whatnot), even if just for fun. ;DI've got the 16-bit dsPIC tools and such, just need a reason to crack open the box and get'em going 8) Quote Link to comment Share on other sites More sharing options...
Goblinz Posted December 7, 2007 Report Share Posted December 7, 2007 Hmnnnnn...... I want one, sounds a bit like a 303. Dunno if I want to substitute a couple for some 6582s in my Wilbabeast though, wouldn;t be a MB-6582 then. I think I may have to build another midibox, which is good. By building the MB-6582 I feel that I'm missing out on learning about the MBHP and how it all fits together.... So quite a few projects now... MB-6582, Mr Midi thingy, MB-FM, Swinsid and something else I'm looking at ;) Think I may have to cancel some holday at some point. G Quote Link to comment Share on other sites More sharing options...
Wilba Posted December 7, 2007 Report Share Posted December 7, 2007 By building the MB-6582 I feel that I'm missing out on learning about the MBHP and how it all fits together....Sorry for the off-topic, but I disagree... they are the same MBHP modules just assembled onto one PCB, and where possible, I've even kept the same part numbers. The PCB makes it smaller, and a bit easier to put together (less wiring, no DIY power supply/BankStick), but you still can and should learn how it fits together by looking at the schematics and wiring diagrams.

Goblinz Posted December 7, 2007 Report Share Posted December 7, 2007 I understand it's the same modules that make up the MB-6582. Don't get me wrong, I'm not against the MB-6882 in any way, I think it's an amazing thing you have done for the community there. I just feel that it will be a greater learning experience for me to learn about building the modules seperately as well, I certainly want to build a set up so I can mix and match, try different things out and learn how they all work. Eventually i'm looking at designing my own midibox so I need to learn about each module in depth, unfortunately the only way I seem to be able to learn and take information in is by doing rather than reading.
