Two people who you wouldn't mind listening to in conversation no doubt. Richard D James (aka Aphex Twin) and Tatsuya Takahashi - the guy behind Korg's analogue resurgence first met while collaborating on the Monologue analog synth Korg released as a mono companion to the four voice Monologue.
Richard D James was asked to contribute to the project and one of the things he brought to the party (aside from a bunch of patches) was the ability to introduce microtuning - a way of creating non standard scales - making the difference between notes not equal temperament, which is something almost all current electronic (and mechanical keyboards) adhere to.
In this transcription posted on the Warp Records website of a conversation between RDJ and Tats, we can see that this ability is something that they both hold dear. And while you read it in full, you can listen to a track composed by Richard D. James entirely on Korg gear:
A couple of classic quotes:
RDJ:I just used to select a single note, adjust the master tuning of it to taste and then base the whole track around that, something I've done ever since, just intuition and maybe a bit of rebelliousness.
"It's very simple, but do you want your music to be based on an international standard or on what you think sounds right to you?"
"I recently made a tuning on the monologue that I matched to an improperly calibrated SH-101 that I was fond of"
