Microtuning (per real time SysEx messages iirc or a bulk dump) is a feature of the GM standard. Though it's said on that page the standard allows for 128 pitches to be set, all of the devices I ever owned only provided 12 which would repeat every octave. So you can eg tune your GM piano to werckmeister or a flute to an oriental scale, but with the ordinary GM synth it is not possible (I think) to do what is shown on your pic.
Someone already told me elsewhere that softsynths and hardware must provide microtonality. When you say, it is very tricky with midi, I now understand all of that. But software like and provide MIDI and you can play hardware MIDI synths with it. So when it is possible there, there must be a chance for a microtonal MIDI. A new MIDI Standart with microtonality would be helpfull. Anyone played a mono or poly VCO-Synth through MIDI with a microtonal software?
...and only suitable for monophonic lines as long as you don't hack further by using multiple MIDI channels (plus multiple instances of the synth, if it is single channel) That said, for monophonic stuff it does work quite nice. I once built such a thing in the Logic environment (sigh, those were the days). Still, for GM synths as eg Bandstand it is perfectly possible to do polyphonic microtuning. Just that most of them (don't know about Bandstand) will only support tuning the twelve pitch classes for all octaves. So it would certainly be of use for some to have a microtune JS plug. I'd play with it for sure :) Actually I could, using Logic as my luxory MIDI processor, only so few of my plugs support General MIDI standard... Some aspects of GM were actually really useful. Hearing your strings in just intonation is a pleasure :cool:.
