[sdiy] paia midi2cv8 question

[Michael Ruberto]

i use the el-cheapo 4124 trannies for this purpose in my own modules. i was 
planning to run the LEDs supply from the midi2cv8's 5 volt supply since the 
analog output section is powered from a separate +-15V. however, the 7805 
regulator on board is supplied from the +15. shouldn't the regulator 
compensate for most of the current switching interference and keep it 
reasonably isolated from the analog supply?
