I actually just thought of this but the SSD has to load every time you go thru a patch, it maybe a bit jumpy because of this. Just a thought. It does not do it every time, but it jumps a patch above or the one below, but when it settles its ok. Honestly think its down to loading patches....but using the up and down button it behaves itself. I also notice it jumps sometimes when scrolling thru samples, both A and B, but its not a deal breaker, but Im glad Im not the only one who has this issue...can u call it an issue tbh?.
