Synth Freq.

gambrino

Hello , i would like to ask if someone changed the code in the library Synth.Spin (which is in Spin language) , to propeller assembly language .
Is it possible or it's very complicated ?
Thank you in advance

gambrino,

It's possible... the main reason I didn't do it was because I didn't want to mess with Assembly division at the time. That said you can pre-calculate the values with Spin, and just pass them into Assembly. The same registers exist in Assembly as do in Spin. Just use the MOV command to set the CTR's, FRQ's, and DIR's from within Assembly.

Since the initial question has been answered, may I ask if anyone has done any
calculations on musical note-to-frequencies using Synth? I'd love to have this list
if someone has done it.

Do you mean a note-to-frequency table? There should be plenty of those on the Web, or you could generate one in Excel. I used one many years ago to play simple tunes on a Z80.

Duh, I didn't think about this not being "Synth" specific! Thanks for hitting me in the head. [noparse]:)[/noparse]
