dcreatorx Posted November 17, 2005 Report Share Posted November 17, 2005 Hi . . I want to ask how many audio in/outs i have to put in the design. !audio in and 1 audio out x SID ? If not, explain me how this is working please. Thanks ! Quote Link to comment Share on other sites More sharing options...
kokoon Posted November 17, 2005 Report Share Posted November 17, 2005 yes, 1 IN + 1 OUT per SID. although you can chan them internally and have just 1 IN and 1 OUT overall. but it's better to mix them with an external mixer. Quote Link to comment Share on other sites More sharing options...
dcreatorx Posted November 17, 2005 Author Report Share Posted November 17, 2005 Ok, that's right . . .thank you kokoon, as always. Quote Link to comment Share on other sites More sharing options...
dcreatorx Posted November 17, 2005 Author Report Share Posted November 17, 2005 And the same for the MIDI IN/OUTS ? ;D I forgot to ask you that ! Quote Link to comment Share on other sites More sharing options...
thefRont Posted November 17, 2005 Report Share Posted November 17, 2005 afaik you only get one midi in and one midi out per MIDIbox SID.You can get a second midi out + one midi thru if you build the LTC module.but you really need only one midi input because you can address all the SIDs on different midi channels.

kokoon Posted November 17, 2005 Report Share Posted November 17, 2005 yeah just 1 midi in and 1 out. that's the whole point of the 1master+3slaves idea. you can assign each to it's own midi channel if you want. Quote Link to comment Share on other sites More sharing options...
dcreatorx Posted November 17, 2005 Author Report Share Posted November 17, 2005 Ok, I understand . . . just 1 core module will mange the MIDI connections. It should be the one who carryes the master PIC, right ? Quote Link to comment Share on other sites More sharing options...
kokoon Posted November 17, 2005 Report Share Posted November 17, 2005 yes it's that one. the internal communication between the master core and the slave cores is still via midi (sysex) but you don't need to bother with that. Quote Link to comment Share on other sites More sharing options...
dcreatorx Posted November 18, 2005 Author Report Share Posted November 18, 2005 HEy , I'm here asking again ! Talking about audio IN/OUT(s), what kind do you exactly use ? RCA,BIG JACK . . . :) Thanks as always. Quote Link to comment Share on other sites More sharing options...
TK. Posted November 18, 2005 Report Share Posted November 18, 2005 Sidenote: the INs are a nice option, but not really useful. Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
dcreatorx Posted November 18, 2005 Author Report Share Posted November 18, 2005 Yes, I thougt on that before . . . the IN(s) are not so important, since youdon't have to input any audio signals on the box. But . . what kind of parts do you use ? RCA, BIG JACKS . . . Sorry for repeating the question, but i should know it ;D Thanks a lot everybody.

TK. Posted November 18, 2005 Report Share Posted November 18, 2005 Big Jacks, because my ADC (Hammerfall DSP Multiface) has the same onesBest Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
Jurbo Posted November 18, 2005 Report Share Posted November 18, 2005 dcreatorx - You can use RCA (cinch) or 6,3 mm (1/4 inch) jack, whatever suits you best. What decides this is the equipment you are going to use to get the sound out. Most mixers accept a 6,3 mm jack, so that's what I went with. Jack->jack cables are thick and durable. And, when you are connecting to RCA equipment, the jack->RCA adapters (with RCA->RCA cable) are less clumsy and give a better connection than RCA->jack adapters.Although I'm sure other opinions exist... ;) Quote Link to comment Share on other sites More sharing options...
dcreatorx Posted November 18, 2005 Author Report Share Posted November 18, 2005 I have to power the jack-in ? I bought 4 stereo ins and i found that each of them have 4 legs with wholes. Can somebody specify if I have to power them ? If not, I just leave alone the power leg ? Thanks :) Quote Link to comment Share on other sites More sharing options...
Guest analouge Posted November 22, 2005 Report Share Posted November 22, 2005 Hey. I suppose you shouldn't power the jack contacts in any way.Some contacts have a switch in it... that's maybe the reason for the four pins.Else, you should find a schematics for plugs like that (I mean, Jacks, XLRs etc... Then it's very very easy to see what pins to use. There are loads of them on the internet, and if you have a mixing console or any studio/PA equipment, it's very likely that those schematics can be found in the manuals of these ;)I'm not that into the actual SID project, but I work with PA and studio apps almost every day, and that means a lot of cable soldering. And I do not know of any reason why to power any jack contact... You need to use two of the pins on the contact. (Three if it's a stereojack). But to me it seems you got a mono contact with a switch used to cut the contact when there's no plug into it.Hope this helps ;)Have fun!Ingebret Quote Link to comment Share on other sites More sharing options...
dcreatorx Posted November 25, 2005 Author Report Share Posted November 25, 2005 Thank you so much for the information. I'll look for an schematic ! :D Quote Link to comment Share on other sites More sharing options...
illogik Posted November 25, 2005 Report Share Posted November 25, 2005 Hi Synth-o-mania is right; jacks shouldnt be powered unless you wanna blow up your speakers!!For the sid (and most other synths) you don't need stereo jacks because it's a mono signal (like for example a guitar)a mono cable has 2 wires; a wire with the (audio)signal and a wire with ground connections; typical mono jack plug:====>the "====" part is the body (or ring); you connect this to groundthe ">" part is the tip; you connect this to your audio signalso if there are more then 3 pins (on a stereo) jack socket you've got a switched socket; two of the pins (one is usually connected to the tip) are connected together when there is no jack in the sockets; this connection switches off when you insert a jack.hope this helps explain Quote Link to comment Share on other sites More sharing options...
