Dynamic ramping parameters during a perf-pass.

Dynamic ramping parameters during a perf-pass.

Subject	Dynamic ramping parameters during a perf-pass.
	Hi Csound, I have a slider that outputs to a global variable: gktarget. gktarget is meant to be the target value of a linear ramp. The ramp has to respond to the change in this variable so that it always ramps from its current value to the new gktarget, i.e., the old ramp is overridden by the new one and creates zigzags. It takes the fixed amount of time for each dynamic ramp to finish. It seems all ramping opcodes take only i-rate parameters, but here I seem to need k-rate changes. But if I used reinit for the ramps, there might be artifacts. In PD, it seems to be as simple as to hook up a slider to trigger (target-var,delay) message that is fed to the line object and the output will be like what I described above. I wonder what would be the standard way of doing this in Csound. If I can use a few opcodes instead of an explicit logic, that would be great.

	Have you tried putting the signal from gktarget trough portk opcode before setting it to any parameter? 2016-02-11 1:34 GMT+01:00 Beinan Li <li.beinan@gmail.com>: Hi Csound, I have a slider that outputs to a global variable: gktarget. gktarget is meant to be the target value of a linear ramp.

	I can't tell you how many times I've written custom code to do exactly what tlineto does. If no one is against the idea, I might add linto and tlineto to the list of 'Envelope Generators' in the user manual. That's the first place I would go to when looking for such an opcode?

Subject	Re: Fwd: [Csnd] Dynamic ramping parameters during a perf-pass.
	Yes, that might make sense. Many users might not think "envelope generators" when they need automation. Then again, the envelope generators could be included in the automation category, along with line, linseg, transeg, expseg, cosseg, jitter... 2016-02-11 12:10 GMT+01:00 Richard Dobson : > Maybe add a category for "automation"?
