on my experience with my Oberheim MC 1000, which is the only MIDI equipment I’ve ever used with ReNoise, I can say that the two wheels and the two sliders it has (wooww!! ) jump at about one value out of 10 rate.
Maybe the wheels jumpt at a slightly higher value, but this is mainly due to the different kind of movement.
My hands are really not for surgery, so it could also be due to me
Alright, so I finally got an answer out of the good people at Edirol.
I’ll post this, in case other people have the same problem.
The following is the answer from Chris Douglass, Lead Product Specialist, at www.Edirol.com;
Hi there,
Where did you get your PCR-50? The very first shipment of the PCR’s had this issue. But it’s very unlikely that you would find one of these new. You can have your keyboard upgraded at an Edirol Service Center. If you’re in the U.S.A. that service center is here at our facility. If you’re in Europe, you should contact info@edirol.co.uk to find a service center to upgrade your keyboard.
If you’re in the U.S., let me know & I can arrange for this. We charge $20 for this upgrade.
