Any idea on how to make a glissando on a sampled sound ?
Depends on how you’re playing it, but basically just a ramp on the playback speed of the sound will do the simple version. The problem is that, since you’re just changing the speed, it only sounds like a convincing gliss over a very narrow pitch range. Arguably, it’s just not convincing at all, since the formant is moving with the pitch…
There are more sophisticaed ways, but they get much more tricky. You could take a look at the CNMAT stuff posted in the "analysis to additive resynthesis" topic (under MaxMSP as well, one level up!).
You can do it using a harmonizer with a short delay (< 200 ms) in a
feedback configuration. It won’t sound like a glissando on the
instrument most likely, but you might find it interesting.
optional lowpass filter (NON-RESONANT!)
back into harmonizer
The optional lowpass filter allows you to stop the glissando (more or
less) at a given frequency.
Note that this is a continuous glissando, so it’s always going,
regardless of input.
Yes, sorry this was a stupid question…
I’ll twice next time.
