But note that you probably don't want to define your table in the
"pass" section but either globally or earlier in the same instrument.
Otherwise the table will be recreated every time you jump, which is
unnecessary.

Subject: [Csnd] Simple phase modulation gui
Hi,I'm just approaching to phase modulation,my idea is to build an algorithm
inspired by the classic DX7 but not as emulation, I serve as the basis for a
course on Csound that I will keep, this simple idea is clear enough for a
beginner?thanks

With pvstanal th eonly other option I can think of is having two
tables. reading the file in the new table and then changing the table
number dynamically. Still this will take time and won't be immediate.
Maybe Victor can add a loopend variable to the opcode?

Subject: Re: [Csnd] best way to jump in a song
At the end I resolved in this way: when the loop is activated, I jump to instrument 2 that will use the mincer opcode (it can change start and stop dinamically) and I turn the instrument 1 down. If the loop is deactivated, I do the reverse: move from instrument 2 to instrument 1.
I don't think this is the best option, but until now this is the only solution I have. I will use this code for a software for blind people, so I'll make it clear that if they activate the loop they have to press play again.
If there is another solution please continue this thread! I'm learning a lot about csound from all of you. Michele 2011/11/25 peiman khosravi <peimankhosravi@gmail.com>

With pvstanal th eonly other option I can think of is having two
tables. reading the file in the new table and then changing the table
number dynamically. Still this will take time and won't be immediate.
Maybe Victor can add a loopend variable to the opcode?
