All,
Paul, So you finally come over here too! ;O)
Now I can see I can use a sine oscillator, square it and this will give me the bell curve, only problem here is that I get two 'bell curves' for the price of one cycle, which brings me neatly onto my next problem..
Notice that squaring the sine gives you a DC-shifted sine of double frequency.
What I need to do is to change the amplitude and/or pitch of each 'pulse' at the zero crossing, great I can use Zerox, but, how do I then change the value?
I had though of feeding the output of Zerox into a 'sequencer' which controls the pitch and amplitude of the sine oscillator, but I can't see a 'sequencer' type of module..
As always in chuck, if it ain't there, you program it! Straigh chuck-code will do.
So, There are two questions firstly, Is there a sequencer module planned? and secondly, if not, how can I get round this? can I use the output of Zerox to increase a counter and use an 'if' statement to change the values of the sine oscillator? will the use of multiple 'if' statements be quick enough?
I've been pondering over doing a generalized sequencer. However, the feature that I lack is the ability to have a number of control-values that I either control manually or have control signals fiddeling around with. I want to unplugg things and hook things up independently with the execution of that sproc. Some work has been going on to investigate that over here, but I don't know what has happend in 1.2 in relation to that. The modulars/Synthi-A sense of plugging and unplugging/rerouting signals as they go on is powerfull and how one works in real life. On the Synthi-A one naturally "plays" by just briefly patch in one of the patch-pins into the matrix. Infact, just having that patchability in graphics would be cool, but I'd guess the OpenGL interface is doomed to do that work, no? Cheers, Magnus
