Hi Steven, I second Hector suggestion. During these days, while exploring Blue, especially since I've discovered the BSB, I had the instinct of moving the knob and the sliders in the BSB windows to tweak the sound in realtime. Without too much change in the CSD file generation, and without the need of digging in the csound api, you can implement this with OSC, simply replacing the values of the krate variables filled with the gui controls with variables that you read via OSC and setting them to the gui objects value at the beginning of the playback. There should be ready made OSC library for java, IIRC. To keep the compatibility with the non realtime rendering you could sum the OSC values with the ones you get from the BSB guis and consider the initial position of the widget = 0. Keep up with the good work, c. Steven Yi wrote: > Hi Hector, > > Thanks Hector!
