Since SOF only allows a maximum multiplier of -2.0 it takes a lot of (paired) SOF instructions to implement (even numbered) left shifts. Why not take the LOG, adding N during the LOG, and then take the EXP to multiply by a factor of 2^N? Since the assumed format for a LOG output is S4.19 we can mult...

(1) A minor point: Jumping to any page indicated within the table of contents in the SPINAsmUserManual.pdf actually takes you to a different page. The offset of the table of contents entry to the page jumped to is 3 pages off. (2) SPINAsmUserManual.pdf, page 33 or 36 (in the XOR description). This l...

Frank: Sorry, I now see that I failed to indicate where number 3 was relevant. I was referring to this location: Knowledge Base => SpinAsm instructions and syntax => AND (or OR or XOR). I also noticed that PACC is mentioned in the AND and XOR explanations but it is absent from the OR explanation. I ...

I have a number of questions relating to the accuracy and resolution and the values of some of the internal operations. 1. What are the accuracy, resolution and dynamic range of the LOG2 operation? I did not see this stated anywhere. The LOG2 output is divided by 16, indicating at least a 16 bit dyn...

Frank:

Thank you, I will check both of those sites out.

Frank: (1) OK, thank you. I did not know if there was anything specific to guitars or other musical instruments that would be bad for electronic organs in your reverb and chorus algorithms. (2) As I previously stated, an explanation of what each pneumonic acronym stands for would be useful in your d...

I must explain that I am hearing impaired; I can only hear sounds up to 3KHz and I am totally deaf to sounds at 5KHz and above. I am also not musically inclined, hence these acoustically related questions. (1) Would the default programs in the FV-1 provide for suitable Reverb and Chorus effects for ...
