Posted: Tue Jul 28, 2015 8:03 pm Post subject: Is microtonal tuning possible? |
|
|
Is it possible to specify a microtonal tuning curve across the full length of the keyboard (I'm really interested in trying Partch's 43-tone system, but even being able to implement quarter tones across the keyboard [so, just to clarify, what I'm thinking about is that, instead of 88 keys covering the usual span of octaves, 88 keys would cover half the amount of octaves, with each key being separated by a quarter tone (even less than that in the Partch system) instead of a semitone] would be nice)? I see that the SV-1 Editor allows you to individually tune notes by plus or minus 100 cents, but I don't see anything that would allow you to transpose individual notes.
Thanks. |

Okay, so I've been doing a bit of reading since initially posting this...and I'm thinking there might be another way of setting microtonal tunings across the whole keyboard VIA MIDI.
In this regard, since I don't see anything in the manual about it (except on the implementation chart, which simply states it is supported), how do you enable a manual dump of SysEx data from (and to) the SV-1? |

Korg don't seem to want to share any details regarding SysEx on the SV-1.
The additional soundpacks revealed that there were features (splits) and samples (upright bass) in the ROM on the machine that weren't accessible with the original release firmware.
The SV-1 seems to share a certain amount of heritage with the PA series of keyboards, and the suspicion remains that there are further features and samples that are simply not accessible without additional documentation.
It may well be possible to apply a custom tuning, but without better support from Korg, I don't think you are going to be able to achieve what you want. _________________ PaulR

Thanks for the info. Along with posting this thread, I also sent an inquiry to Korg USA about doing a manual SysEx dump, but I'm guessing from the tenor of your post that I shouldn't hold my breath while waiting for a positive response.
I'm convinced that there simply *has* to be a way of initiating manual SysEx dumps without using the editor, and the limited number of front panel keys on the unit is making me think that it might be worth an afternoon (especially since I have an editor-based backup of all of my presets) to hold down random button sequences to see if I can make any progress through dumb luck.
The thing which is really frustrating to me is that, in the SV-1 editor, it shows frequency information for each individual key in a particular tuning, but the fact that a user can't directly specify a frequency (and the fact that, even after tweaking parameters in the XML file to allow larger values, individual note tuning seems to be locked at plus or minus 99 cents) really limits tuning possibilities. As you said, it really seems like there are more possibilities than what are being allowed (though perhaps, in a roundabout way, that's smart marketing as well -- instead of releasing something which is fully-loaded from the beginning, just slowly unfurl system features in order to extend a product's shelf life). |

I wish (and hope) that the plan is to unfurl more features. Trouble is that the last update (OS 1.2) came out in 2010, so I suspect that further updates are unlikely. _________________ PaulR
