I've just update b9 with some optimisation of the launch time for MOD files.
Also added:

PLAY MODSAMPLE sampleno, channelno [,volume]

See the CMM2 manual for PLAY MODSAMPLE.

Here are some great mod files from https://modarchive.org/index.php?request=view_top_favourites to get you started

modfiles.zip

So much memory's with the mod files

Thank you Peter

I have to test on the marble pico with 8mb ... if my work give me some free time !

Theory is when we know everything but nothing work ...
Practice is when everything work but no one know why ;)

Sadly not so good results by now..

OPTION COLOURCODE ON
OPTION KEYBOARD GR
OPTION SDCARD GP10, GP12, GP11, GP13
OPTION AUDIO GP6,GP7

When I try, to Play a MOD File, I get a "Mod playback not enabled"

But when I try to reserve the MODBUFF, unfortunately my pico gets into panic

I was only able to persuade him to continue working with flash_nuke.uf2

It panics, even if I try to set the modbuffer right after reinstallation without any options

As Jim says the size is in Kbytes

Quote If sizeinK is not specified then it will default to 128Kbytes

However, it shouldn't have let you put in a silly value. This was a bug in my parsing which I will fix.

NB: also in the next version it will force the value to be divisible by 4 (needed for flash erase)

Thank you, even if i just reflash the mmbasic Version it still "panics".

Tested b9.

On a working system (VGA) with A: drive containing 30+ files: *** PANIC *** after OPTION MODBUFF ENABLE 128. The PANIC is a non-volatile panic. After reboot, the pico connection to USB terminal program, but no video is shown. Something is realy confused.

After nuking the flash, and a clean install I could OPTION MODBUFF ENABLE 128 and modbus plays the MAXITREK MOD file.

Apparently pico cannot free up space when the A: drive already is used.

Volhout

P.S. Does the MODBUFF contain the whole .MOD file? Or only the samples data ?

I've updated the downloads to avoid the panics (hopefully)

https://geoffg.net/Downloads/picomite/PicoMite_Beta.zip

The whole mod file is loaded into the buffer so it needs to be at least as big as the biggest file you want to play - now checked properly

Yes. I get perfect sound from both versions powered by the USB. My cards use a linear regulator and there are various Pico clones that also don't use switchers

Have you downloaded again? This is fixed in the latest download. Timestamp on the latest in the zip file is 10:45

Yes, but it was overwriting things it shouldn't have. Set MODBUFF to be bigger than the biggest file you want to play.

On my boards with a 16Mb flash I set it to 1024

Tried latest b9, all looks well. Perfect job...

Only in doubt what MODBUFF size to keep on a standard picoVGA. No dynamic allocation, so A: will get small if you reserve 512k. I guess I'll stay with 128k for now.
Impressive these example files. So much music in such small files.

Incase PWM is 32kHz and you update 16kHz, what is in the "in between" samples ? average ?

Two the same. It just keeps the PWM frequency up while not hammering the cpu.
In the case of the DAC it is only updated every second time
