That's not for every plugin a big problem. I noticed that the phaser gets finer LFO-changes than those displayed. So if I klick the arrow 2 times then the 2-decimal-value doesn't change but the LFO-frequency changes. Back to the AM pitch shifter: Changing the values with an editor in the .rg-file works. Not really user-friendly but it's a workaround.

Unfortunately my Ubuntu 11.10 has not the needed library- and header versions, so I can't compile RG here and try to find the bug My holidays before christmas should give me the time zo update my Ubuntu to 12.04 LTS.

Using the AM pitch shifter thing as a test bed, the knob that moves in integer increments seems to be working just fine. The knob that lets you set a floating point value has big problems. The display appears to be limited to two decimal places of precision, but the arrow buttons obviously let you make changes in finer increments than that. The result is that you have to click repeatedly in order to see a visible change. Once you've made the change, either by using the arrow buttons or by typing a value directly, that change gets corrupted somewhere along the way. Try to change to 1.03 and the result is the knob gets set to some fantastically wrong number like 1e-10. That kind of wildly nonsensical number is usually an uninitialized variable, but it seems like there could definitely be type conversion and/or precision issues mixed up in here too. I'm weak on floating point math, so this might be a common pattern I don't even recognize. I spent some time poking around, and only started to get the idea of how all of these many intricate little puzzle pieces fit together. This would just take more time than I have to sort through and work out, but it's probably a really simple and obvious problem. -- D.

[Rosegarden-user] Entering values for LADSPA plugins directly
Hi all, some plugins are unusable for me because I cannot enter arbitrary values. The AM pitch shifter plugin has a range from 0.25 to 4. But I cannot enter values directly. It doesn't seem to be a language problem (messing with , and .). Even if I start Rosegarden with LANG=en_us.utf8 rosegarden I cannot set the values directly. Setting them with the mouse (turning the knob) works but is way too coarse. Entering the value in the input field or using up and down arrows always leads to the minimum value of 0.25. Rosegarden version is 11.06. Any ideas? -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
