Welcome to the Music and Sound forum on GD.net. Pull up a chair, listen to some tracks by your peers and discuss all things music and sound. We're happy to have you.

I was wondering if someone would be able to tell me at what frequency middle c is played at, and by how much the frequency is changed every half step. From this I can make better DLS Instruments, and in the end better sounding stuff. Show me what you got
Traditionally the A above middle C is given the frequency of 440 Hz. Every octive above doubles that freq. (ie the next highest A is 880 Hz) and every octive below halves the freq (ie the next lowest A is 220 Hz)
To find the change in each half step take the 12th root of 2 (because there are twelve half steps to an active) and that will be the change in frequency each note. I'd give it to you but I don't have a good enough calculator handy.
Multiply any frequency by that and the result will be the next half step up. I didn''t really make that clear in my last post. The difference bewteen every half step is different over the whole range of notes.
