Quote from: plexified on January 21, 2023, 02:04:55 PMThe BOSS tuner registers the sound of the actual guitar tuning and the adjustment range of the tuner is +/- 435Hz to 445Hz. You can also use an external tuner and tune any way you wish.What I would point out is that your guitar is now the reference point for Alternate tunings INSIDE the SY 1000 COSM. Now the SY 1000 will be able to tune in the range of whole tones and Cents for Fine tuning. Lets use a few real world examples. You go to a jam session and you tune to the bass player or another guitar player or a keyboard. No problem. Your in tune with everybody. If you tune to A 440Hz its a Concert tuning same thing, your in tune with the Concert tuned instruments. If you wish to tune to 432Hz you should have no issues if you are the only player or others are tuned to 432Hz. You can use the Alternate Tuning inside the SY 1000 to be tuned A = 440Hz at the guitar and 432Hz (-32 Cents) inside the COSM module. Here you can use the conversions to do this. Because things are not perfect in tuning world you have to do what works for you. A = 440 would need to be lowered by -31.76 cents. Your Fine tune ablity inside the SY 1000 is +/- 50 cents for each string, a very fine tuning feature. Example : Frequency Difference(432 Hz -31.76 cents)435 Hz −19.78 cents436 Hz −15.81 cents437 Hz −11.84 cents438 Hz −7.89 cents439 Hz −3.94 cents440 Hz ±0 cent441 Hz +3.93 cents442 Hz +7.85 cents443 Hz +11.76 cents444 Hz +15.67 cents445 Hz +19.56 centsgenerally 4 cents per tuning interval. So if you used the SY 1000 tuner @ A = 440Hz you could go inside the COSM area and you would tune the entire guitar down - 32 Cents for each string.Conversely, you could tune to 432Hz and raise the COSM tuning inside + 32 Cents to meet A = 440Hz. Here is a conversion site that can allow a deeper dive into tuning and making it all work, scroll through ! : http://www.sengpielaudio.com/calculator-centsratio.htmSo Tuning is one of the magical features of the BOSS/Roland Modeling. Each string can be tuned octave up or down and +/- 50 Cents for each patch.
Quote from: GearSounds on January 21, 2023, 02:21:16 PMUnfortunately you would be wrong on multiple levels but allow me to clarify. Firstly let me just say that the oscillating synth function of the sy1000 is the only thing that differentiates it between the sy300 meaning that if you cannot use the oscillating synth function you might as well just get an sy300. I tune to 432 Hertz so right now I cannot use that function as it will automatically play a 435 Hertz note or whatever the synth is tuned to. What is worse is that it is also listening for a 435 Hertz note so oftentimes it will even play the note below what I'm actually playing as I am tuned to 432 hertz. This means that having a guitar tuned to 432 and the synth tune to 440 would most of the time trigger the correct notes but many times would trigger the wrong notes making it completely useless and unusable for 4:32 Hertz players like myself. Now that I see that I lost $500 on this unit I'm pretty upset as it doesn't seem there is any way to actually tune the oscillating synth notes to 432 hz. Those notes don't actually react to Bends and are simply triggering a sound.
Quote from: GearSounds on January 21, 2023, 02:24:35 PMI hate to say you're wrong but I believe you're wrong. I don't know a single Roland product that does 432 hz and I can't find a programmer to help.
Quote from: Bill Ruppert on January 22, 2023, 06:43:13 AMWhy would you want to tune to 432?
Quote from: Bill Ruppert on January 22, 2023, 07:39:47 AMOh....Thanks, Todd
Quote from: Brak(E)man on January 21, 2023, 03:18:20 PMThe OSC synth and gtm would be the only thing ( with maybe the exception of the harmonist fx , haven't tried that) that would be affected when in chromatic mode not when set to non chromatic. But that said it works fine in all pitches for me with fretless in non chromatic mode. And btw you're mistaken, the OSC synth do react to bends, slides gliss etcThe synth doesn't really listens for a 435 or 440 hz note otherwise.The instruments, the dynamic synth , the GR300 , vio etc etcplays the string as an oscillator in whatever pitch it's in.And the OSC synth is definitely not the only thing that differentiates the SY-1000 from the SY-300.There's tons of things that's different.I use both units with both fretless and fretted guitars and the micro and quarter tones as well as the long gliss would not be possible if what you describe is plausible.When I fi use the sequencer set to different pitches it's always relative to the pitch I'm playing. In other words if I'm playing a quarter tone let's say a sharp minor second then all the intervals in the sequencer will be in relation to that exact pitch.

Quote from: GearSounds on January 23, 2023, 03:31:37 PMThe sy 1000 osc synth does indeed "lock" to notes and many of my favorite patches in the sy1000 function this way. I will get it on video but try doing bends on every patch and you'll find what I'm referencing.
