Noob question about sampling and Octave change


Well this question has been bugging me for long time and I would like to get some info.

So lets say I record a sample in Note C and then insert it in Renoise pattern writing the original semi note lets say “C-3” But what happen if I change to D, C# etc? How can it be a D or E if the original sample was a note C?

If you have original instruments in Renoise or VST this “problem” will not occur because the notes coming straight from the instrument but not when sampling. How do people here work it out?

Maybe there is a sheet for this?

Cheers! :grinning:

If you are sampling a synthesizer, you could press the e on the synth, sample it, and link it to the e note in the renoise sampler. When you do this for all notes, sample f and link it to f in Renoise etc, it’s a lot of work, but you get a good replica of the sampled synth.

If you just sample one note of your synth, let’s say your c, by default it’s spread over all notes of the keyboard in the Renoise sampler, but then, for all notes which aren’t the c, the pitch is changed by Renoise, so you can create a melody. But since it’s the same sample, the higher the note goes, the shorter the played sound will be, because it’s the same sample, only played at a higher pitched. The good thing is, it’s less work :slight_smile: But then again, it won’t sound as your original synthesizer, when playing notes that are away from the c base note.

Thank you alot! That was very helpful

So this method must be more flexible anyway then running VST’s and External synths that taking lots of CPU right?

It will take some time surely but I think the results gonna be very good :slight_smile:

And followed question: If I have a tb-303 pattern going how do I know which note I should put so it sounds correct? Or is there an option to play it without a specific note?

Just sample the whole tune, you will never get it to sound like a 303, when you chop the sample up in specific notes.


Yes, using samples usually don’t take a lot a CPU. :+1:

By default samples are played at their original sounding at C4.
More you are close to C4, more the sample sound will be close to the original sounding, around -3/+3 semitones is find to keep the original sounding.
Of course you can go over this limit as you want, to create a melody or play sample in other ways.

If you just sample ONe note ,you can play it along te whole keyboard because renoise transposes the sample(up down).
If you want to record mulitple samples ( froma rhodes or drummachine), root-base note is verry crucial
If you sample a note F3 , what should you play to get the original F3 note ?
This all depends on the Root note which you set in the mapping editor , so for F3 it’s obvioulsy F3
If you sample a Snare drum from your drum machine which is D3 , if you then play C3 , the sample will not sound like the original because renoise has transposed it 2 semitones down.
So Root note should be set to D3
For intruments the same , you then decide how much the sample will be stretched up down from the original sample .
I mostly sample 4 notes to get a full octave , so each note set to base key(same as original note ) and tranposed 2 semtiones up , to get 12 notes in an octave.
Some only records 3 notes to get full octave , tranposing 2 semi up and 1 semi down .
Basic oldskool sampling stuff :slight_smile:
