I'm trying to create a sweep with white noise with both pitch and volume increasing in a seamless fashion, but Axy does nothing at all and 1xx creates a weird almost like a sputtering noise then settles on one pitch.

help please?

Using the instrument editor, use the volume and arpeggio effect to achieve the sound you want.


Either that, or you could tediously set the song to a higher speed with Fxx and do something along the lines of this:

0-# 00 1 F02
1-# 00 1 ---
2-# 00 2 ---
3-# 00 3 ---
4-# 00 4 ---
5-# 00 5 ---
etc, etc.


Welcome to the forums!

is there any other way? because using the instrument editor, the result is far from seamless for each parameter can only be increased at a large amount, not anything small to not notice, and the speed way is just plain tedious

I'm looking for a nice slow sweep, almost like a cymbal roll, used as a build up to make my song sound more full

and thanks for the welcome =]

You can add zeroes in the arpeggio or pitch section to slow the sweep down. For example { | 1 0 0 0}

I'd just do it the way Mex demonstrated, by using different notes and adjusting the volume column.

just add more 0s before the 1 in the pitch envelope to make it longer.

of course, the slower you make it, the more you'll notice the laddering on the noise timbres (and the less reason you'll have to even make an instrument when you could do it in the patterns.) it isn't possible to get a perfectly smooth noise sweep.

You use 2xx instead of 1xx, but even so it will be too fast.

So I made something too. I add two spaced [u]pitch[/u] envelopes together, for example:
P'[0 0 1] + P'[0 -1 0 0]
= P'[0 0 1 0 0 1 0 0 1 0 0 1] + P'[0 -1 0 0 0 -1 0 0 0 -1 0 0]
= P'[0 -1 1 0 0 0 0 0 1 -1 0 1]

Where P[ ] is a pitch envelope. Similar variations are V[ ] (volume), HP[ ] (hi-pitch), A[ ] (arpeggio), D[ ] (duty) and so on. A dash ' means that the envelope is looped.

This syntax will be the one I am using in the future.
