I'm in need of constant tone generator for SN and AY sound chips

[+mytek]

 I'd like to calibrate the output of two sound chips I'm using in my CV-NUC+ Project via the audio mixer on the MSX Module. I'm not a coder, and this is especially true concerning the Colecovision, so I'm looking for someone that can put together a ROM routine. Basically it can be dirt simple and just output a full volume sustained tone on both sound chips simultaneously (I can always pull one chip when I just what to scope the other). Or even nicer would be to have each tone activated via a toggle action, so for instance keypad 1 = the SN chip, and keypad 2 = the AY chip, press once to activate and press again to deactivate.

 

A ROM image suitable for running from an AtariMax Ultimate SD cart would be the ticket 👍

 

Thanks in advance

 

EDIT: if there already exists something that will do the trick, please be so kind as to provide a link.

I downloaded it and will give it a try tomorrow.

 

Thank you

Ok it appears that that MusicDemo program is only applicable to the SN sound chip and not the AY sound chip, which is ok for starters, and I did find it very useful. Now if only there were a similar program for the AY chip.

Sorry I didn't read your original post properly.  I haven't made the AY version of that code yet.

No worries. using your provided program let me set the SN output to a proper level on my scope. And once I had that it was fairly easy to match the AY output using a DB meter when playing SGM games. Mission accomplished.
