MICROTONALITY

Greetings,

I don't know where seems to be the problem (as i'm so new to Absynth) but microtuning dosen't work propely.

I went on ahead to adjus the Hz of each note and played with only the default pure sine wave to check it plays the correct frequency.
However when i play note C3 that i assigned to play 117Hz, the synth plays a completely different frequency (about 62Hz)!
I don't have this problem with FM8 when i assign it to play 117Hz by tuning the A# plus 7 cents, but it lacks the option to adjust any key to any frequency regardless of cotaves. That's even why i had to dich MASSIVE & FM8 and start tuning with Absynth, but even there i am missing something...

Can someone please help me with this one?

(Ps. For all i care this thread is open for other interestng microtonality discussions as well)

Sincerely;
VACCALEEN

 

Total noob at micro-tuning, but searching for info on this led me to this thread.

I think it's because the octave numbering is different in Absynth, so C3 might actually be C2, or something like that.

I've just tried setting Absynth C3 to 117, and FM8 toA# + 7 cents and tested it in my DAW(Sonar), setting note to C for Absynth, and the A# below the C for FM8.

Got exactly what you described, but to get the same frequency of ~62Hz I had to drop the FM8 note down an octave. As a further test I bumped up both 3 octaves and played simultaneously, to hear them easier and check if they were the same pitch, which they seemed to be, some very minor beating but that could be down to phasing or slight differences in sine wave produced.

So, I think it's just down to the octave numbering being different. Which could make sense as Absynth has an 8 ocatave keyboard in the GUI whereas FM8 has 6.

As a noob though, I could be completely and utterly wrong

 

hi,

maybe this helps. go to patch view.

from the manual, page 47:

"5.3.2 Frequency Menu and Frequency Control

Frequency menu in Trans mode

All oscillators can be set to react to incoming notes in various ways. Thys are kency modes. Using anel’s Frequency menu and its companion thcy control sitting at its right, you can to choose from the following Frequency modes:

• Trans: The oscillator follows the pitch of the played note. The Frequency control deter- mines the transposition in semitones. For example, setting the Frequency control to 1.5 will lead to a transposition of one and a half tone compared with the pitch of the played note. The Frequency control has a resolution of 1/1000 of a halftone.
  
  
• Ratio: Tranposes the oscillator according to a frequency ratio (for example along the har- monic sequence: 2 corresponds with a transposition of 12 halftones, 3 with a transposi- tion of 19 halftones, etc.). This mode is especially useful when using frequency modula- tion and ring modulation.
  
  
• Hz: Fixed pitch in Hertz. In this mode, also useful for frequency and ring modulation, the oscillator ignores the pitch of the note played. Rather, the pitch of the oscillator does not reacts to information like pitch bend or to signals coming from an LFO, but it can be controlled via an Envelope.
  
  
• Note: Fixed pitch corresponding to a selectable MIDI note. This mode is similar to the Frequency Mode Hz, but is more appropriate when you want to use the oscillator on a note-bound frequency (e.g. 60.5 = C3 plus a quarter-ton)."
  

 

Hi 33tetragammon,

I believe what Vaccaleen is trying to do is create his own tunings, which is different to an oscillators trans mode.
This is done on the the Tuning tab on the Perform page. It's covered in 10.7 page 152 of the manual.

Here's a Wiki on Microtuning, which explains it far better than my attempts to:

Cheers!

 

thanks for that! you are right!
i thought the Osc Trans Mode would make a difference, but it didn't when i checked just a few minutes ago.
my bad!

carry on!

 

For the record, the lowest pitch is called C-2, so this is the Yamaha numbering. EG: middle C is called C3.
