Yeah Andrew! TRACOPOWER with symetrical 12V is good for CV outputs.... after do more tests ( was busy this week) I found that the random noise in the video is from an ethernet powerline device . not from the supply or seq! (mesured at 50mV (100mV P-P)) 10 cm between core and PSU. internal ripple of the seq is consequent with the meanwell! 30mV (60mV P-P) Peter your filter rocks! attenuation of 30mV ripple to 5mV (10 mV P-P) and good sleekage. with the scope and filter it's ok! but without the scope and with the filter the CS crash immediatly after power on! i see the real benefit of the filter and hazard made the filter permit me to "force" bug! (extra cap of 2200uF will act as reserve of power) the seq current is 270 mA , without (for the moment) the IIC and midi indicator external leds. i test with USB powa' or classic transfomer/7805 and lab PSU and the seq is stable.... The crash is caused by low load of switching PSU , the PSU go to "idle" mode! (5.050v to 4.930v)... Have to do tests with more load on the PSU... perhaps a regulator or UBEC to load the switching PSU would do the trick! Or SEQ with extra external ledstripes! The simplest way is to go with classic design PSU and leave the idea of powering BLM from SEQ... from this switching PSU. a supply for BLM another one for SEQ and one for the line driver CV rack! there will be for everyone also it's a bad idea to have long extension of power rail with high current low voltage...

Ok here it is :) 1 fader pack with PID and LED pcb, also keeping the original fader PCB which interconnect passive part of the fader, audio and signaling PFL circuit everything fit in original studer cassette InOut pcb with 8 ch AD-DA and 64Din 64 Dout 19' rack with hi Q vero PSU +5 and +/-15, the core32 and the line transmiter And the beauty :) I'm proud of what I done, and really like to thanks Thorsten for the beautiful software and all other for help around this place. At this point everything working great, but it's not finished... I have to run it with full 8 fader pack to be sure it's a viable system, and I'm not able to fund this in a short range. Zam
