What is the frequency resolution in Kyma? Can you produce custom scales and intervals that involve fractions or cents or do you round to the nearest cent?

The frequency resolution in Kyma is 0.0026 hz. At 4 c (middle C), that would be about 0.000172 cents. You can specify frequencies in hertz, in pitch (octave number followed by pitch class), or as a MIDI notenumber with an optional fractional part. For example to specify one cent above middle C, you would use 60.01.

Are there any alternate tunings built in?

There is a Tool for setting up new scales and testing them out using any sample or a synthesized waveform. Templates are available for:

- Octave equivalence scales specified as either ratios or cents with respect to the tonic
- Microtonal scales of from 5 to 50 equally spaced steps per octave
- Completely arbitrary mappings of frequencies (specified in hertz) to keynumbers
- Two-interval scales generated by raising an interval to successively larger powers (with wrapping to keep all frequencies within a single octave)
- In addition to arbitrary ratio scales, the tool also has built-in Equal tempered, Just, and Pythagorean buttons for instantly generating scales based on any keynumber as tonic

Once you have defined a tuning, you can save it as a text file, so you can reuse it later.
