Hi list,

I wrote an alternative intonation system, performed by indexing with pchmidinn decimal part.

With array it works. With table some index fails the right reading.

Does not work table opcode or am I wrong something?

I attach two examples.

Greetings

Andrea S.

	Quick read of the code suggests that table opcode requires a power-of-two length table. Will check further.... you should use te tab opcode instead. ==John ff On Sun, 23 Dec 2018, Andrea Strappa wrote: > Hi list, > I wrote an alternative intonation system, performed by indexing with pchmidinn > decimal part. > With array it works.
