Hi all,

the URL of the calculation-tools:
http://www.modular-planet.de/_aspekte/tools.html

Various calculations are possible:
- frequencies of half-tones (adjustable steps)
- detune with cent-values
- cent-values of different frequencies

Unfortunately the descriptions are in German!
Who can translate it into English descriptions? (My English is tooooo 
bad :-(((((

Hi Josef

These is a very interesting calculations. For the translations see below.

Sorry for the slight offtopic: I had another wish, which is not really
required for modular systems but would be very useful for older samplers: 
The relation of the transpose/pitchbend value against a certain detune or
BPM with a given Pitchbend amount. I give an example:

I have an Casio FZ-1 Sampler. I load a Sample with 108 bpm, but I need it
at 132 bpm. The pitchbend amount is set to two half notes. To get the
detination tempo I have to transpose the sample for let say 3 half notes
and a certain MIDI-pitchbend value. I'd like to have something like:

 1.) base tempo (Ausgangstempo)
 2.) pitchbend range 
 3.) -> resulting transpose value 
 4.) -> resulting pitchbend MIDI value 


I tried this already back in atari times with GFA Basic, but I was not
lucky.

The first one is not that easy, because the terms are not really correct -
also in german. But the approach is very interesting. Lets see:



Frequenz-Berechnung von Teiltönen
1. Grundton              -> base frequency
2. Stufe des Teiltons    -> which step shall be calculated, if...
3. Anzahl der Stufen     -> ...one octave is divided in n steps
4. Frequenz des Teiltons -> resulting frequency of the step given in #2

"Teiltoene" is the same as "Obertoene" which is translated with "partials",
but this is not correct. You say: we have an octave. This octave is divided
in n steps, where n is given in the field #3.

Example with temperatured classic 12 note octave:  
1. 440 Hz
2. 6th step
3. of 12 steps 
4. -> 622.2539674441618 Hz

The same can be reached with 
1. 440 Hz
2. 3th step
3. of 6 steps 
4. -> 622.2539674441618 Hz





The other ones are easier:


Verstimmung um Cent-Wert 
=> get the frequency with a certain detune amount (in cent)

1. Ausgangs-Frequenz             -> base frequency
2. Verstimmung (Cent-Wert)       -> detune in cent
3. Frequenz des verstimmten Tons -> resulting frequency






Cent-Wert-Ermittlung 
=> get the detune amount (in cent) with a known detuned frequency

1. Frequenz des verstimmten Tones   -> frequency of the detuned tone 
2. Zugehöriger Halbton              -> the base note
3. Cent-Wert (Grad der Verstimmung) -> required detune in cent

Hi Florian,

thanks for translation and correction!

There you find the English version of the tools:

Is all correct?
