Hurray! Some folks are going to say that we're missing the point of voltage-controlled oscillators, but precise tuning control of both oscillators was one of the Sub Phatty's big selling points for this happy owner (me).

I had a faux tuning issue of my own yesterday, which I'll record here in case someone else has the same problem later.

In the morning I recorded some bass loops into my iPad, and in the afternoon I tried to layer them with Sunrizer (one of the best iPad synths). Something did not sound right! I pulled out my Korg bass tuner and the Sub Phatty was sharp. Odd... I checked the init patch, and it was dead on -- which made me think it was a patch problem, not a hardware problem. Inspecting the panel (which hadn't changed much since I saved the bass patch), I noticed that (a) pitch modulation was considerable and (b) LFO rate was quite slow. I turned down pitch modulation and the faux tuning issue disappeared. Speeding up the LFO to vibrato speed would have worked too, no doubt.

In case anyone else is having tuning issues across multiple octaves since the official Sub Phatty Editor (and associated firmware) release and having no luck with note calibration and fine tuning adjustments... I found that the SubPhatty_Calib_Init_Values.syx file Amos provided in this thread followed by the standard note calibration procedure outlined in the manual solved my problems.

My tuning idiot moment: hooked up my MiniBrute through the Ext Audio In of the Sub, MIDI out of MB to Sub then started palying. *Ugh* the D and the A keys are way out of tune with each other. WTF?!?


um, oh yeah, I left the Sub in MeanTone tuning. Doh!

can someone please repost the SubPhatty_Calib_Init_Values.syx i have some issues in the highest octave

help help anyone please. liek to have my sub in tune again!!
