You also mentioned the possibility in an earlier message on this thread that the pitch adjustments on the DX7S may not have the required resolution whether on the coarse or the fine setting.?
Resolution for microtuning on DX7S is 1.17 Cent, any key can be retuned to any frequency in whole range of instrument. That means that scales with many steps in octave can be done, steps can be equal or unequal, and there’s also no need to keep octaves pure, octave interval can be omitted. Also inverted keyboard is possible, or different tunings in different keyboard zones.
To get exact whole numbers of Cents is not possible, some approximation is always necessary, but resolution is enough dense to mask it - nobody can hear such small steps. It can only be a small problem in chords because of beating but still it’s usable.
Very interesting that there are a few stretch tunings Daniel.
Those differs only by width - some have smaller slope, some larger.
What do the columns marked -2 … 8 represent ? Are these the settings for fine tuning on the DX7ii ?
It has nothing to do with coarse or fine tuning in FM algorithm. I suppose they are Cents deviation, so it has to be translated in DX7S/IID/TX802 steps in microtune function.
Not microtonal in the strict sense, Wendy Carlos in her album Switched on Bach 2000 used many alternative tunings on synthesizers using her own custom tuning tables and software implementations.
E?
Yes, of course… I did also microtonal works, using ethnic, historic or my own tunings.
