[CAUT] IPod and Tune lab

[Jim Busby]

Hi Keith,

My graphs do NOT look like these. Mine are more arched. I've tried to play around with things, and I did make it better for one tuning. What I really want is a tutorial that takes me step by step through the setup. I can't find one.

Do you know of anything better than the downloadable manual? It seems to lack the instructions I need. Are there any standard files for common pianos? That might be a good place to start. I know you say that the learning curve is greater, but it seems like I'm having to reinvent the wheel here...

I'll play with the instructions you gave below and see if it makes sense. One of my friends tunes very well with his tune lab, but he cannot make mine work like his. (Mine's an IPod and his isn't)

Thanks.

Usually I use either the 4-2 singleoctave or the 2-1 singleoctave. You have to hit the auto button to adjust the upper curve to the new selected partial scheme. Notice the increase in the center spread on the lower graph and the sharper treble on graph 2, 2-1 octaves. Narrow gap in the bottom graph is desireable
You can now use the manual adjust to vary the upper graph. I use the 8 button adjuster. Usually I don't need to adjust much.

The upper graph is the curve the program sets the piano to when you hit the exit button. Nothing else changes the curve except going back to the graphs and changing things there. Play with it. There is more of a learning curve with tune lab but you can do stuff like perfect 12th tunings etc.

If I don't get a graph that looks like these, I retake the readings. Sometimes the split scale method has to be used

All,

I'm still trying to get Tune lab to work on my IPod. (I touch)  Here's the problem; when I take the readings for the Tune Lab on the IPod, then tune while comparing the tuning to both the SAT and Verituner the Tune Lab is 4 or 5 cents different at B2 (or around the break). Verituner and SAT are fairly similar. At A4 (A440) all 3 are dead on. Aurally I can't stand it either, so it's not just that the Tune Lab is different - it's just not right or I'm doing something wrong because friends that use Tune Lab on their PDA's end up with great tunings.

How can I get a good tuning w/o trying to tweak the specs??? Anyone know? I mean, with SAT and Verituner it's hard NOT to get a good basic tuning even w/o messing with it.

Thanks.
