  Doubt about the global command 01        Go on top to this Page

Let's say I have a tone loop wav sample tuned to C-4 and want to change the pitch to C#4, during playback, using the sampler global command 01. What's the correct hex value, suposing I'm starting with 0100?

Usually, samplers have another command, which is portamento to note. Psycle's sampler doesn't have it (Sampulse does, but since it is unfinished...).

Also, traditionally, trackers had two ways to do portamento, the amiga way, and the linear (Fasttracker) way.

In the first case it tells how much it increased/decreased the period each tick. Since note frequency increases in power of two, the portamento is not lineal.
The amount was in reference to the period of the note. (856 was the period for middle C. later in PC's it became 1712 to give more space for fine portamento).

In fasttracker, each note was always separated by 64 fine values, and thus, the change of pitch was linear.
The amount was in reference of this fine (except the fine portamento, which is slower).


The problem is that psycle's basic sampler doesn't use any of them. It increases the speed of the sampler, working similar to amiga, but a bit reversed.
This also makes that the pitch is faster or slower depending on the note that you start the portamento.

The truth is just that the internal sampler is too simple, and that Sampulse is unfinished and a bit complicated to use compared to it.

So, basically, is the 01 global command useless?

I didn't say that. I said that one cannot expect it to do the exact same thing that it does in a conventional tracker.

It still does portamento up, and portamento down. It is just not as easy to know how far the change will be.

But in practice, it is. Because it doesn't work precisely. In music it's critical.

Maybe it can be used as a creative tool but I think it's better to use some dedicated vst for this task.
