If it works, why not. I have tried lots of ways to create cool music on the Lynx. The problem is the limited memory. You cannot just turn MIDI to Lynx music. It eats up all memory.

You can ?

Just have to stream the midi commands from the card -> see my synth examples

I am not an expert here. But basically setting AUDIN is like:

 

    and #$10
    ora #$b
    sta IODAT

So the bit to set corresponds to the mask $10

 

I think this is teh reason that not the register, but a shadow variable is set

i know that feeling

Thanks, this confims what I saw/understood.

Do you confirm that AUDIN to use is bit 5 of IODAT and not AUDIN ?

some old code i found. maybe this explains how i do it

file_test.inc

[AUDIN - reality and emulators]

The boot loader needs to be in both AUDIN switchable banks, as the power up state is undefined or better, differs between different lynx versions.

Thus the first thing the bootloader code has to do is to bring the bit to a defined state.

Where you put your directory is then up to you.

I decided to have it in bank0 only, and switch AUDIN back and forth each time I access it. the bank is encoded in the upper bits of the offset as the block number is already using 8 bits.

[Lyxass 0.51 binary for windows]

maybe a bad idea :-((((

luckily i was able to find the problem within minutes.

 

[Lyxass 0.51 binary for windows]

ugly bug:

 

lyxass accepts

stx (tmp)

and

sty (tmp)

but translates it to

    STA ($00)    ;
    STX $00        ;
    STY $00        ;

really? i never got simis runnign in the emulator even with eeprom. good work

So a quick search and I found that Duranik has a mod player for the Lynx that you can convert 4ch mods into lynx music, though I'm unsure how you implement the player or where you would find that. Has anyone used their tracker before?

yes sure, you find the source code for asm and cc if you look for it. but it is very limited in terms of cpu, memory and supports no effects. But this was discussed already 17 years ago...

somewhere i still have the source files to access 8 and 16 bit for different kind of eeproms for cc65. if you need it i might dig them out.

Somebody broke sound in Gates of Zendocon from 0.971 to now. Doesn't seem to work in 0.98 or this 0.99 version. The laugh of Zendocon is my first test for sound compatibility.

there is no offical numbering. everybody numbers his compiled release different. would be nice if you meantion the source of your download.

[HandyMusic]

Just a remark: the instrument export is really bad. I agev up on making it better. Thus you better optimize them afterwards or take from sass.

[HandyMusic]

what a strange coincidence, indeed.

well it does not write out this complicated SASS files, but directly the assembler code (with macros for better readability).

As it is creating directly a lnx file (and there is a reason the lnx file looks very similar to the handymusic example :-)), you can easily see how to include the files into your own project.

[Sound loop programming for HandyMusic]

so you want your keyboard sound like a lynx, not connect the keyboard by midi to a real lynx?

You can do it at 60Hz as well. I think HBL is not best suited since you lose the time you would otherwise have in Vblank. But it should work as well in HBL ?

The tree is nice In general you'd want motives with vertical gradients to show off the colors.

ONe question: how much is the music distorted if you use this?
