Pianoteq is easy and fast for designing and hearing tunings. Organteq does not tune up as intuitively.
Tuning scripts can be generated online at Scale Workshop
The Peterson StroboPlus HDC tuner can be calibrated for cents deviation and is accurate to the tenth of a cent.
The Just Intonation Primer by David Doty is a very concise and beautifully written explanation of the concepts.
Dorico Music Notation software allows sampled instrument to be retuned with Helmholtz-Ellis Pitch Notation. Download HEJI fonts at plainsound.org.
HALion Sonic sampled instruments are bundled into Dorico and work with HEJI. The string instruments have vibrato which defeats the point of tuning. Some composers are using Note Performer with Dorico. I use Kontakt Cremona Quartet, vibrato can be turned off. Below are settings required for this to work.
In Dorico, Library/Expression Maps/Expression Maps Data/Microtonality playback/Pitch Bend;
Pitch bend range/2
In Kontakt, the sampled instrument needs to be set to receive pitch bend information from Dorico. In Kontakt: press wrench button/click on: Edit All Groups (turns brighter red)/Add Modulator/External Sources/Pitch Bend. The slider needs to be set at 1 semitone.
I have designed charts which help me keep track of the HEJI accidentals and spellings.
Below is the tuning lattice. My 1/1 is A, the key for the female voice in Khyal, Hindustani North Indian vocal music. The lattice could extend in any direction infinitely; this is a screen shot of a TouchOSC midi controller that I designed to play out these tunings. Download pdf here.
Below is a chart that I designed to navigate the harmonics and corresponding pressed notes to the 13th harmonic of the string quartet in ratios with HEJI accidentals spellings. Download pdf here.
