The interesting thing is that code exists for PowerSDR already. It is probably part of the Open Source portion of the code since it is purely display/control related. It is also using later code as you can see in the demo that it is using the Pretty Betty skin. I am guessing that this part of the code has not changed much and therefore would drop into the current beta code with a minimum of hacking. This would go a long way toward squelching the, "gotta have a tuning knob that doesn't change with the focus," crowd. It would also show that you can have both a control surface and "virtual knobs" on the display and have them work together. The only fly in the ointment will be that the knobs won't turn as someone manipulates the virtual knobs in the display. I don't think that knob-oriented people will notice and as soon as you turn one of the smaller knobs, the corresponding slider on the display will jump to the appropriate position. That seems to me to be a small idiosyncrasy. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 br...@lloyd.com +1.767.617.1365 (Dominica) +1.931.492.6776 (USA) (+1.931.4.WB6RQN) _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/
