Using Pro 3īs CV outs to control Rolandīs System-500 modular system.

Using Pro 3īs CV outs to control Rolandīs System-500 modular system.

So Iīve tried this by reading the manual (page 116-118). If I tune note A correctly then A, B and C in the same octave are in tune, but then it starts to drift off. Adjusting the CV scale and offset doesnīt help much except that I can move the tuned area of 4 notes up and down by changing the offset.

If I use a USB cable and play the Pro 3īs keyboard via Kentonīs USB Solo CV/gate interface then the System 500 is perfectly tuned over 4-5 octaves.

Does anyone have any experience with this problem or clue how to fix this?
