Re: OricExos - making the impossible

So how are the audio signals going to be handled - summed? I could imagine a 4-voice polyphonic Oric synth with summed signals might have some distortion/drive issues, or at least .. I'd hope that would be the case.. ;) I'm just a software guy, all I know is that on the AY the volume from 0 to 15 o...

Re: OricExos - making the impossible

Sorry for the confusion - I am actually *pro-* having actual physical controls, but this is because I'm a musician/composer and for me thats sort of a vital aspect of instruments these days. But, anyway, was just an idea .. Oh but i can totally see the point of physical controls while creating some...

Re: Novalight - very fast tape loading

It does not work under WIN7 64bit. Is there a solution to work on this system? Thank you. error Access Denied Which version and command line are you using? When I run novalight_1.1k.exe from the command line I get the list of parameters, so that tells me that at least the compiler used does work fi...

Re: OricExos - making the impossible

I know a few who would hang you for this comment :lol: I'm not saying that the Amiga has horrible sound, just that the non merged stereo is horrible, specially with a headset: There's a reason why pretty much every single Amiga game or music disk you can find on Youtube has been remastered with cor...

Re: OricExos - making the impossible

All 4 sound output are "as is" - standalone without mixing. The 4 speakers will be attached with wires and proper connectors to every board (next to the purple/white wires which connect the master reset button on the picture). If anyone has an idea for something better - now is the right time to sh...

Re: OricExos - making the impossible

Regarding the music, there are two known midi players, midipsg from Fabrice (but I could not find the sources), and another one from Wasky which replays the Game of Throne music and comes with the sources: https://github.com/DJChloe/got Spectrum coders have a bunch of converters as well (midi2ay, mi...

Re: Novalight - very fast tape loading

I assume you have checked already if any of the code of your loader happens to match sections of the ROM, in which case you could also do something like a generic "create" routine that copy snippets of code from ROM.

Re: Better code generation (for CC65)

That's actually a nice difference, specially in term of code size. Maybe everybody should try to rebuild their programs in -O3 and see if they notice any bugs, because there used to be some code generation errors, which is why it was not enabled by default, but if it works, that could be a good firs...

Re: OricExos - making the impossible

For the audio - it's OK, both options are easy but what type of connectors do you need, so I can prepare them? The ideal would just be a standard stereo female headphone jack, can easily connect that to my videocapture card or audio input on my speakers. I think the pseudo-code formulas to describe...

Maybe it should just be put in a transparent case, with some blinking things :)

Nice info about Telestrat and Microdisc connectors:
(...)
So, the hand-written notes on your pictures are confirmed. :)
That's borderline criminal...
I wonder how many telestrats and microdiscs got destroyed because of that, why did they use the same connector???

Re: OricExos - making the impossible

Awesome :)

So, two questions:
- What did you finally came up with for the soundchips: Mono, Stereo (and if Stereo, how is it split?)
- What are the video mixing algorithms you have implemented

So basically I can start thinking about what I can do :D

Re: Microdisc connectors

I'm actually having the same (similar) issue. I do have have a Master Microdisc, a Slave Microdisc, and a HxC floppy emulator. My old Oric Microdisc PSU is scary, heavy, and doing some zzzzzzzzz noise, so I'd like to replace by something modern and compact that could power up to 4 drives, and the Or...
