Just for Information, new SwinSID Firmware is out (ATMEGA 8515) http://www.forum64.de/wbb3/board65-neue-hardware/board288-sid-co/board294-swinsid/33292-swinsid-firmware-updates/#post406561

by the way there is also a new way of getting 8-Bit Filtered Sample out of a Stock SID 6581 / 8580 here are some Demos playback best on a Real C64 or the HOXS64 Emulator others wont playback the new Trick well ;) http://noname.c64.org/csdb/release/?id=72563 http://noname.c64.org/csdb/release/?id=72678 So for the Future I would like to see this new feature in MIDIBOX SID ... yeah an 8BIT Filtered - Sampler without additional Hardware except some RAM / ROM ;)

Under Item number: 130202520908 they also offer now single TDA 1543 so you can grab as much as you need now... Happy Soldering ;D

Also a design suggestion for the DualCore PCB, I would put the 24MHz Oscillator as near as possible to the CLK in, so you may flip the AVRs and put the Oscillator to the left bottom side and the TDA to the right up-side... This would minimise the RF noise of the Oscillator ... I my desgin for the C64 I just put the Oscillator under the AVR but that reguires a thinner socket for the AVR ;) Just my thoughts ... Maybe you share your schematic file? For playing around with the Parts position.

some say sound quality of a TDA 1543 is better that a thing you should decide for yourself and your taste of how the sound is... ;-) but an other thing is price ... look with one TDA 1543 or whatever DAC you choose you can connect TWO AVR's for Sound so the Calculation goes better than any original SID Chip... the Cheapest SID Chip I can get here in Germany will be around 15 Euro for the old 6581 or 20 Euro for the newer 6581 R4AR or the 8580R5 ... for that money you can get a lot of AVR's and even the DAC Chips.... so stop crying about the DAC Price... and start building and using them ;D btw. the AVR mega 8515 used in here is about 1,70 Euro bei Reichelt.de and the 24MHz Oscillator is about 1,55 Euro so for the Dualcore or Stereo SwinSID you need one DAC one 24MHz Oscillator and two AVR mega 8515 ... do the math...

well at voti.nl they still sell the desired TDA1543 for 2,50 Euro ... so where is the problem? This DAC is also used in some external CD Player DAC Projects for it's good Sound also look on Ebay the sell DAC-Kits with this Chip for xxxx Euro Prices very heavy... So I bougth some pieces from voti with no problem at all, fast shipping too... And also very easy to connect, with other DA you need extra clock and parts and so on...

another idea if the normal filter in the sid is not enough, why not just build the SwinSID and ask Swinkels for an improved Firmware with your desired Filter Settings... The AVR is about 1,70 Euro here in Germany (Reichelt.de) ;D

Hi nILS, here ya go and get it ;D http://rapidshare.com/files/112571896/4nILS.zip.html The Song Melissa_D is a Stereo left 6581 right SwinSID The Old_Friends is only the SwinSID But in this Song are either the Samples to silent or the Sid Voices to loud... The Songs with Samples I tested matched perfectly so just listen... 8)

new Firmware also here in the Midibox SID ... SwinSid article http://www.midibox.org/forum/index.php/topic,9386.60.html 8)

@TK ofcource can you... no problem and as I saw Swinkels updated some part of his site with some new Demos ;D If anyone has a favorite Sidtune which he wants to listen played by the SwinSID please tell...

Just ask Swinkels himself and he sends it to you... he is also currently working on his new site as he said to me... but I don't know when this will be ready... or I put it here, I hope it is ok?! http://rapidshare.com/files/112219029/SwinSIDX2.zip.html

Here are the PIC of a DualCore SwinSID, I just piggypacked the 2 AVRs on Top of eachother and so it is very easy to connect em both... of course I used a Socket on the underlaying AVR so I can flash em individually when new Firmware shows up, last Firmware was from 1. May evening ;D which now sound very very close to the original even the pitch matches and the noise generator also

Hi everyone if you like you can download and listen some one on one demos left the 6581 R4AR right the SwinSID with actual Firmware ;D http://rapidshare.com/files/111795777/6581SwinSIDnew.zip.html http://rapidshare.com/files/111815078/6581SwinSID_Test2.zip.html Have fun while listening... and always Remeber the SwinSID can do much more than only SID Sounds! Here is the SwinSID playing alone with Digis ... http://rapidshare.com/files/111795778/SwinSIDnew.zip.html 8)

As I am also in email contact with Swinkel he is going to put everything together on his Site so you can grab all files there in a few days. He also informed me about the new Firmware which is a real Hammer :o so stay Tuned and keep watching his Site. I am also posting for the C64 Freaks in the german www.forum-64.de board for the Computer Part which was the original intend for this chip but as synth in a Midibox it is also a perfect choice an may save many c64's live ;D Soon there will be some more Soundexample of Real SID Tunes Compared to the SwinSID.

Hi I have drawn a Shematic for the SWINSID STEREO option... so where should I load it up... or who wants to have it for checking and maybe testing... ::)

http://rapidshare.com/files/102892761/SWINSID-DEMO.mp3.html just listen an tell which channel plays the Original SID and which Plays the SWINSID I made a PCB which holds em both and recoded this SID Tune which was originally a mono tune, so I had coded it to play on both SIDs at the same time. Best Regards Crisp

Hi TK, could you please tell more about how the 2 AVRs are connected, you mentioned on the SWINSID Site something like a free parallel port of both AVRs? Do you have a shematic to share? Maybe Eagle like? ;) I already completed a single SWINSID, and I also miss the Information that you have to Burn the AVR FUSE (low=c0) to recognize the external 24MHz Oscillator... so there is definitly more Info to spread for people to build this thing. Thanks in advanced Crisp

Just wanted to keep this one alive and also wanted to know if there is any news on what parts to buy ;D my soldering iron need work to do ::)

Yep I know and the audio examples are also nice... but what speaks against it to use the SID also for Talking Singing and so on? The thing that annoys me about the speakerjet is that you have at the moment an extra RS232 connection to a PC for the letters to speak... I think it would be better to make a MIDI Note to Letter conversion... Like pressing on the MIDI Keyboard C-1 and let it SAY 'AAAAAA' Or let it say 'AAAA' when a controller ist set to the desired value and controlling the pitch with the keys... while thinking about it ... controller would be the better solution... But thats only my thought... ;)

Yep that were Really cool examples, and that's why I thought about porting this C64 code to the PIC because our Speech System don't uses Samples only the 3 SID VCOs and therefore it doesn't need so much cpu Time for generating Speech... So my Idea for this is to use one SID for Singing in Robotic Voice and another SID for the Music or something like that 8)

Here I present you the link to a page where you can grab the Sourcecode of the SID Speech Synthesizer, maybe someone can port this to the PIC Processor so we can use it with the MIDIBox SID ;) http://noname.c64.org/csdb/release/?id=48099 and the DEMO for watching and especially listening http://noname.c64.org/csdb/release/?id=48042 ;D

Hello here is something that might be of interrest for the upcoming MIDIBOX SID V2 Look here for a small 4k C64 Demo with Realtime Formant Speech Synthesis! Based on the Klatt Speech Synthesizer www.c64.sk ftp://ftp2.untergrund.net/breakpoint/2007/C64_demo/BP07-Demo.d64 This might be some funnie thing to add to the new MIDIBOX SID. Enjoy watching... Runs on WIN VICE (www.viceteam.org)

Hallo da ja viele C64 für den Sid geschlachtet werden, wollte ich mal fragen ob vielleicht einer hier im forum so nett ist für einen kleinen Unkostenbeitrag einen oder mehrere 8565 VIC II zu überlassen bevor die auf den schrott wandern. Habe einen defekten C64 mit eben diesem Chip kaputt. Vielen Dank schon mal. Grüsse

Hello, I surfed the net for some informations about Soundhardware and found an interesting PPT file which has a very interesting information on Page 20 with following readings...: Yamaha FM registers in apparently random order (like Japanese House numbers) Bug found by Williams/Watts in 1985 in YM3526 Did a workaround so quick time to market for Commodore computers Bug found again by Linux programmers when trying to emulate Soundblaster registers 2004 - OPL2 core now integrated into the South Bridge of the motherboard's chipset Bug now in every PC? (>1 Billion?) The twenty-two registers (20-35, 40-55, etc.) have an unusual order due to the use of two operators for each FM voice. Channel 1 2 3 4 5 6 7 8 9 Operator 1 00 01 02 08 09 0A 10 11 12 Operator 2 03 04 05 0B 0C 0D 13 14 15 you can find the PPT here: http://research.microsoft.com/users/lyn/soundcardhistory.ppt I just wanted to know if this bug even exist in the opl3 used in the MIDIBOX FM? Thanks a lot... I am building it at the moment... also a SID Module... Greets and Thumbs up for the good work!
