Hallo,

I have the following problem: I wanted to use 'samphold' to
generate a noise LFO, that means, an LFO that changes it's
output value at an adjustable (low) rate. I first generated
noise using 'rand' then passed it to 'samphold'. The 'gate'
port of the 'samphold' was fed by a vco in squarewave mode
with a very low pulse width.
It worked fine, but there is a little thing I don't like. The
low pulsewidth vco is not an ideal 'gate' generator for the
samphold. I want the gate function to be 0 all the time except 1
sample every cycle of it's frequency. How can this be done ?

My idea is that this is something we aren't able to do easily
in csound at the moment, so I would suggest a new opcode called
'aout spike kfrequency'. It should generate spikes with
adjustable frequency that are just 1 sample period long. Maybe
we could add another parameter that defines for how many sample
cycles the output should go to 1. This would then be a
super-precise PWM oscillator (which generates nice aliasing (-;,
but it's use would be the triggering of samphold, not to create
an audio signal).

Or do I miss something, an this functionality can already be
done with another opcode ?
