I'm away from a real Atari 8-bit computer and a scope, so I was hoping someone in the know can help me with this. What I am seeking is the typical audio output (at maximum volume, peak-to-peak voltage) straight out of POKEY's 'AUDIO' pin-37 with a typical 1K pull-up resistor, and the same for GTIA's 'BELL' pin-15. Thank you in advance, - Michael

At this year's Revision demoparty, I gave a presentation about music on the VCS with a survey on available routines and tools, some thoughts on how this might have influenced music culture (from a demoscene point of view) and finally introducing TIATracker, my new sound routine and sequencer. A recording is available on YouTube in case you're interested:

Hey guys, so a few weeks ago I purchased an "as-is" ColecoVision off eBay. The graphics were all garbled on the display, so I assumed it was either a power or video RAM problem. Being a very novice electronics tinkerer, I figured I could give a go at repairing the console. After replacing the power switch, verifying the power supply was providing the appropriate voltages, replacing the video RAM with the 5v RAM mod, and repairing some broken traces on the RAM bus I got functioning video! However, I am not getting any audio out of the Coleco. I next wired an RCA cord to Pins 7 and 8 on the audio chip and confirmed it is outputting audio. Suspecting a broken trace somewhere between the audio chip and the RF modulator (due to my experience with the memory bus) I used my multimeter to follow the signal from Pin 7 (audio out) along the various hops on the board. Confirming no break between pin 7 and the last point before entering the RF modulator, I removed the metal box from around the modulator, separated the daughterboard from the modulator, and reconnected the board with wires so I may explore inside it. I have found no broken trace or component between pin 7 and C88. The only symptoms I now have are the staticy audio (and no game audio as far as I know), and the video signal occassionaly gives out. I'm stumped as to what the possible issues could be. I've made a YouTube video of the issue in hopes of getting some interesting leads from those on this forum. That video may be found here: https://www.youtube.com/watch?v=ME-nVOafMpA Thank you for any time and advice provided for this.

My NES is being stupid. When I try to hook it up to play, I cannot get the game audio, only a constant, obnoxious buzzing. I've tried hooking it up using different cables... I've tried connecting it to different TVs... I've tried using the RF thingy which didn't work, then I tried the back up RF thingy I have which also didn't work... then I tried using the red/white cables which didn't work, then I tried the back up red/white cables which also didn't work. Everything else seems to be functioning normally, just no audio....and who can play with no audio? I don't want to buy a new system. I've had this one for almsot 30 years and I want it to work. If anyone has any suggestions, or knows of someone I can send it to have it repaired, I'd appreciate it. Thanks!

Hey all, This is my first post here on the forums, so hi everybody! I adore classic gaming and I absolutely love my woodgrained six-switcher Atari VCS / 2600 System I bought a while ago. I love it so much in fact that I want to record the game footage off of the console. So I've searched the net and in many video's and topics I came across the word 'VCR' and 'DVD Recorder' so I went watching for one of those things. The thing is though that most of the topics are from overseas (I live in Europe myself, The Netherlands) so some inputs on the backs of the recorders are different. For instance, I don't have to connect a 'F-connector' to connect the output plug of the Atari into the VCR or DVD Recorder. So, in short; I did not find that much info about it in my own region. This is the method I think will work (I'm not into video electronics or anything, so please correct me if I'm wrong - just my intuition speaking here.) DVD/VCR Combo Player (HR-XV28S, Pictures & English Manual attached below). 1. My Atari VCS output plug will be connected to the AERIAL on the DVD/VCR Combo Player. 2. I will then use the RF.OUT to connect it to my ANTENNA IN on my television to see and hear what I'm actually playing. 3. I will then use the DVD/VCR OUT composite signal to connect it to my capture device and hit record on that. So, here are my questions: -Does a VCR/DVD player duplicate the antenna signal to a composite signal? (So that it comes out of RF.OUT and DVD/VCR OUT like I described above, I'm not certain about this.) -if it does, can I use it as a passtrough device (meaning, without recording anything on VHS or DVD-R) and send it directly into my capture device? Or does it need to record on physical media? -If not; does the signal only come out of one of the two outputs? (composite for example; I'm able to split this signal with some cheap AV 1-to-2 Splitters) Is this the correct setup (and way of thinking) for recording an Atari or any other coaxial retro gaming device? I really want to know! I hope you guys can help me with this, I've been struggeling with it for a while now. Thanks! HR-XV28S Manual.pdf

Forgive me if I'm posting in the wrong area, I didn't see a Commodore 64 specific thread, but I'm using a stupid tablet and it's possible I overlooked it. I have a question regarding the use of digitized sound effect and speech on the C64. I'm pretty familiar with programming, and have even made several games using BASIC with ML subs, but I can't figure this one out. Why is it that some games can play digitized audio over two voice music without stopping all the on-screen action, but some stop all sprite movement and audio before playing the sample? For instance, Way of the Exploding Fist has no trouble playing the digitized samples during the action. Thanks for reading!

Hey all. I would like to write a tune or 2, and have no idea how to "really" start. I found this link: http://knox.ac.free.fr/index.php/pc/aytracker but the software does not appear to be available. I found a link to OpenMPT, but I could not find a way to get anything created there into something I can actually compile into a .rom and run in jvIntv. I also do not understand how to take the code from the sound examples on the wiki and join them with the "hello world" program I successfully built last night for the first time. All ideas appreciated. Thanks!

Hi everyone I'm proud to present the MidiBox TIA Cartridge! This is the first FULL midi synthetizer based on the TIA chip and cartridge cased. This is a DIY project, the firmware is opensource. It was not easy. Not because of the technical issues, just bad karma. In 2011/2012 I made a working firmware and a manager under Max/MSP. Because of personal reasons, I put the project on hold. End of 2012, I received a message from Eptheca who asked me the status of the project. With his help we decided to print 3 PCB’s. Unfortunately during this period, the hard drive of my computer suddenly decided to leave me, and I lost all my work: (( I sent the drive to Shanghai to try to recover my data, but of course my disc was one of the non-recoverable 10% (always this bad karma). So now we had the box and the electronics but nothing to put in it. In February I decided to rewrite everything but it took me some time. ... Done! We've now got a new firmware and the application to manage the box. I am inspired by the version 1 MB-SID. I kept all the features of this engine. I improved the management of banks, I dedicated two envelopes to the voice of the TIA which is free, and a few small details that might please you. Here is the features of it: 1 dedicated envelope for each voices(so 2) with optional non-linear curve and Sync which can be assigned to Amplitude and pitch. 3 specifics Mode to mix Modulation matrix and this env Env+Mods, Env*Mods, Env+(Env*Mods). 2 additional envelopes with optional non-linear curve and Sync which can be assigned to Amplitude and pitch. 4 additional LFOs with different waveforms and Sync which can be assigned to Amplitude and pitch. Pitch Bender Portamento/Glide function with Optional "Constant Time Slide". Delays 1 Arpeggiator for each voice(so 2) with optional Sync. Poly, Mono and Legato Mode Separate keyboard zones for each voice (key splitting) allows to play voices separately Extended Mode for keys(all note reponse) or non extended with offset and length. 1 velocity response for each voices (so 2) with optional CC assignment Free controller assignments to Modulation Wheel and Aftertouch LFOs, Envelopes, Arpeggios optionally syncable via external MIDI clock (one for each;) Bankstick support (4 banks of 128 sound patches per stick, up to 8 can be connected) so 32 banks. And much more. Coming soon: wave and CC sequences which allow more percussive sounds (Wavetables) with dedicated banks. Drum or Fx Kit Presets with dedicated banks. 8 Analog I/O 4bit sampling Atari 2600 Joystick and Video touch pad support. There's no CS on the cartridge version, but there's enough room in FW to add it. If someone wants to create it, you are welcome. This firmware is only for 18f4685. You can add MB-Link too if you need it, PORTA.0-7 and PORTB.0-3 share 8 I/O on the AUX connector. No CS; but I designed a Max/MSP Application (windows and Mac compatible): And it has iDevice support(sorry for those who boycott Apple products): I'm trying to finish a Max4Live version, with a common file between both applications that will retrieve the names of banks, patches and all parameters without having to open the input of the midi track and make a CC request (there's no SysEx in Ableton Live). Now i suppose you want to hear it: http://soundcloud.com/bdupeyron/mb-tia-mantua-preset Voilà!!!

I recently purchased a broken Sega CD Model 1 off an auction and did a bunch of small repairs. So far I've gotten everything to work perfectly except one annoying problem that I can't seem to figure out, stuttering choppy audio. All of the obvious things have been checked & contacts have been cleaned thoroughly and the Genesis runs fine on its own. When connected to Sega CD the sound is stuttering from the Genesis headphone port as well as the TV and even when the mixing cable is used. The only time it sounds clear is when a aux cable is plugged into the Sega CD mixing jack with nothing connected to the other end, which I assume is disabling the sound that is coming out of the Sega CD side of things. Anyone ever experience this before?

After a bit of bugging around: It looks like the combination prescale 0/backup 0 is behaving completly strange. a) It will never work with LINKING (channel 0-3 links to 1-4). b) It will not produce sound with some (many?) waveforms prescale 0-2 with backup 0-2 have strange behaviour with some waveforms. even if you change the timer/backup, the audible frequency does not change (but, the linked timer does!). My educated guess: with 1us reload 0 we have 1MHz clocking. Might be the chip is not able to perform the linking anymore. beeing close to 1MHz with the other prescale/realod combinations, it might be that the polycounters do not work as expected. For example, a simple len 2 polycounter (on-off) will just deliver _no_ output signal. There seems to be a difference here in integrate and square mode!? -> Timing issues??? If this is the case, can we emulate this? Most likely not. Anyway, I you like to check out a few things yourself, you are welcome. Maybe then we find out whats going on.

For those who care. Interesting: There is a difference between Attenuation OFF and minimal Attenuation $F (=15). The attenuation register is anyway ...named misleadingly.

For those who care. What is plotted, is NOT the DAC value, but the volume used for square waves. the behaviour of DAC value might be slighly(?) different. Interesting: Maximum volume is 128 (NOT 127). Known: negative values have same output as positive values (aka 1= -1 =255, 127=-127=129). Only 128!=0. Apart from very low values everything looks linear. The "lower nibble" squirk has not been observed.

I added a potentiometer to the RC circuit in Pitfall II: http://www.youtube.com/watch?v=EWONwis4D9Q The music sounds normal with the pot tuned about 2/3 of the way. Overall, the tempo seems to be unaffected. What do you guys think?
