Hi Just tried om-synth cvs Some questions arose: When trying to load the example patches I got messages: Unable to find object /amp_env/Delay Time (s) Unable to find object /amp_env/Attack Time (s) Unable to find object /amp_env/Hold Time (s) How to know which ladspa library is missing and where to get it? (I already have installed swh, blop, cmt from debian repository.) When exchanging patches, how to ensure, the other system can load and play the patches? Will there be any way to save the plugins (embeded) together with the patch? In the "Load Plugin" dialog (text-)keyboard input didn't work. Is there any simple tutorial/example, that would explain, how to make a polyphonic synth (how to let it play 6 notes at once, when pressed on the midi-keyboard). suggestions: allow selected plugins to be duplicated (cloned), including the connections. allow selected plugins to be moved/copied to sub-patches. ladspa-plugins should have a short description of their functionality, how and when to use them. impression: I very much like om's gui, it's really nice the (bezier-)cables (patches) are cool! scrolling is smooth, the zoom function is great ! emanuel
